JPMorgan Chase Financial Company LLC
Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust due October 1, 2020

Fully and Unconditionally Guaranteed by JPMorgan Chase & Co.

The notes are designed for investors who seek a fixed return of at least 42.00% at maturity if the Final Value of the least performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust, which we refer to as the Underlyings, is greater than or equal to its Initial Value.

Investors should be willing to forgo interest payments and be willing to lose some or all of their principal amount at maturity.

The notes are unsecured and unsubordinated obligations of JPMorgan Chase Financial Company LLC, which we refer to as JPMorgan Financial, the payment on which is fully and unconditionally guaranteed by JPMorgan Chase & Co. Any payment on the notes is subject to the credit risk of JPMorgan Financial, as issuer of the notes, and the credit risk of JPMorgan Chase & Co., as guarantor of the notes.

Payments on the notes are not linked to a basket composed of the Underlyings. Payments on the notes are linked to the performance of each of the Underlyings individually, as described below.

Minimum denominations of $1,000 and integral multiples thereof

The notes are expected to price on or about March 27, 2018 and are expected to settle on or about March 29, 2018.

CUSIP: 46647MQZ9

Investing in the notes involves a number of risks. See “Risk Factors” beginning on page PS-10 of the accompanying product supplement, “Risk Factors” beginning on page US-2 of the accompanying underlying supplement and “Selected Risk Considerations” beginning on page PS-3 of this pricing supplement.

Neither the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of the notes or passed upon the accuracy or the adequacy of this pricing supplement or the accompanying product supplement, underlying supplement, prospectus supplement and prospectus. Any representation to the contrary is a criminal offense.

If the notes priced today, the estimated value of the notes would be approximately $941.10 per $1,000 principal amount note. The estimated value of the notes, when the terms of the notes are set, will be provided in the pricing supplement and will not be less than $930.00 per $1,000 principal amount note. See “The Estimated Value of the Notes” in this pricing supplement for additional information.

The notes are not bank deposits, are not insured by the Federal Deposit Insurance Corporation or any other governmental agency and are not obligations of, or guaranteed by, a bank.

All references in this pricing supplement to the closing value of the Index mean the closing level of the Index as defined in the accompanying product supplement, and all references in this pricing supplement to the closing value of each Fund mean the closing price of one share of that Fund as defined in the accompanying product supplement.

The notes are not commodity futures contracts or swaps and are not regulated under the Commodity Exchange Act of 1936, as amended (the “Commodity Exchange Act”). The notes are offered pursuant to an exemption from regulation under the Commodity Exchange Act, commonly known as the hybrid instrument exemption, that is available to securities that have one or more payments indexed to the value, level or rate of one or more commodities, as set out in section 2(f) of that statute. Accordingly, you are not afforded any protection provided by the Commodity Exchange Act or any regulation promulgated by the Commodity Futures Trading Commission.

The following table illustrates the hypothetical total return and payment at maturity on the notes linked to two hypothetical Indices. The “total return” as used in this pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount note to $1,000. The hypothetical total returns and payments set forth below assume the following:

The hypothetical Initial Value of the Least Performing Underlying of 100.00 has been chosen for illustrative purposes only and may not represent a likely actual Initial Value of any Underlying. The actual Initial Value of each Underlying will be the closing value of that Underlying on the Pricing Date and will be provided in the pricing supplement. For historical data regarding the actual closing values of each Underlying, please see the historical information set forth under “The Underlyings” in this pricing supplement.

Each hypothetical total return or hypothetical payment at maturity set forth below is for illustrative purposes only and may not be the actual total return or payment at maturity applicable to a purchaser of the notes. The numbers appearing in the following table have been rounded for ease of analysis.

PS-2 | Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

If the Final Value of each Underlying is greater than or equal to its Initial Value, investors will receive at maturity the $1,000 principal amount plus a fixed return equal to the Contingent Digital Return of at least 42.00%, which reflects the maximum return at maturity.

If (i) the Final Value of one or more Underlyings is greater than or equal to its Initial Value and the Final Value of the other Underlying or Underlyings is less than its Initial Value by up to the Contingent Buffer Amount of 20.00% or (ii) the Final Value of each Underlying is less than its Initial Value by up to the Contingent Buffer Amount of 20.00%, investors will receive at maturity the principal amount of their notes.

If the Final Value of any Underlying is less than its Initial Value by more than the Contingent Buffer Amount of 20.00%, investors will lose 1% of the principal amount of their notes for every 1% that the Final Value of the Least Performing Underlying is less than its Initial Value.

The hypothetical returns and hypothetical payments on the notes shown above apply only if you hold the notes for their entire term. These hypotheticals do not reflect the fees or expenses that would be associated with any sale in the secondary market. If these fees and expenses were included, the hypothetical returns and hypothetical payments shown above would likely be lower.

An investment in the notes involves significant risks. These risks are explained in more detail in the “Risk Factors” sections of the accompanying product supplement and underlying supplement.

The notes do not guarantee any return of principal. If the Final Value of any Underlying is less than its Initial Value by more than 20.00%, you will lose 1% of the principal amount of your notes for every 1% that the Final Value of the Least Performing Underlying is less than its Initial Value. Accordingly, under these circumstances, you will lose more than 20.00% of your principal amount at maturity and could lose all of your principal amount at maturity.

If the Final Value of any Underlying is less than its Initial Value, you will not be entitled to receive the Contingent Digital Return at maturity.

Investors are dependent on our and JPMorgan Chase & Co.’s ability to pay all amounts due on the notes. Any actual or potential change in our or JPMorgan Chase & Co.’s creditworthiness or credit spreads, as determined by the market for taking that credit risk, is likely to adversely affect the value of the notes. If we and JPMorgan Chase & Co. were to default on our payment obligations, you may not receive any amounts owed to you under the notes and you could lose your entire investment.

As a finance subsidiary of JPMorgan Chase & Co., we have no independent operations beyond the issuance and administration of our securities. Aside from the initial capital contribution from JPMorgan Chase & Co., substantially all of our assets relate to obligations of our affiliates to make payments under loans made by us or other intercompany agreements. As a result, we are dependent upon payments from our affiliates to meet our obligations under the notes. If these affiliates do not make payments to

PS-3 | Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

us and we fail to make payments on the notes, you may have to seek payment under the related guarantee by JPMorgan Chase & Co., and that guarantee will rank pari passu with all other unsecured and unsubordinated obligations of JPMorgan Chase & Co.

We and our affiliates play a variety of roles in connection with the notes. In performing these duties, our and JPMorgan Chase & Co.’s economic interests are potentially adverse to your interests as an investor in the notes. It is possible that hedging or trading activities of ours or our affiliates in connection with the notes could result in substantial returns for us or our affiliates while the value of the notes declines. Please refer to “Risk Factors — Risks Relating to Conflicts of Interest” in the accompanying product supplement.

In addition, the benchmark price of each Fund’s Underlying Commodity (as defined under “The Funds” below) is administered by the London Bullion Market Association (“LBMA”) or an independent service provider appointed by the LBMA, and we are, or one of our affiliates is, a price participant that contributes to the determination of that price. Furthermore, our affiliate is the custodian of the iShares^® Silver Trust We and our affiliates will have no obligation to consider your interests as a holder of the notes in taking any actions in connection with our roles as a price participant and a custodian that might affect the Funds or the notes.

Payments on the notes are not linked to a basket composed of the Underlyings and are contingent upon the performance of each individual Underlying. Poor performance by any of the Underlyings over the term of the notes may negatively affect your payment at maturity and will not be offset or mitigated by positive performance by any other Underlying.

If the Final Value of any Underlying is less than its Initial Value by more than the Contingent Buffer Amount, the benefit provided by the Contingent Buffer Amount will terminate and you will be fully exposed to any depreciation of the Least Performing Underlying.

If we or our affiliates are unable to effect transactions necessary to hedge our obligations under the notes due to a commodity hedging disruption event, we may, in our sole and absolute discretion, accelerate the payment on your notes and pay you an amount determined in good faith and in a commercially reasonable manner by the calculation agent. If the payment on your notes is accelerated, your investment may result in a loss and you may not be able to reinvest your money in a comparable investment. Please see “General Terms of Notes — Consequences of a Commodity Hedging Disruption Event” in the accompanying product supplement for more information.

The commodity futures contracts that underlie the Index are subject to legal and regulatory regimes that may change in ways that could adversely affect our ability to hedge our obligations under the notes and affect the level of the Index. Any future regulatory changes, including but not limited to changes resulting from the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), may have a substantial adverse effect on the value of your notes. Additionally, under authority provided by the Dodd-Frank Act, the U.S. Commodity Futures Trading Commission on December 5, 2016 proposed rules to establish position limits that will apply to 25 agricultural, metals and energy futures contracts and futures, options and swaps that are economically equivalent to those futures contracts. The limits would apply to a person’s combined position in futures, options and swaps on the same underlying commodity. The rules, if enacted in their proposed form, may reduce liquidity in the exchange-traded market for those commodity-based futures contracts, which may, in turn, have an adverse effect on any payments on the notes. Furthermore, we or our affiliates may be unable as a result of those restrictions to effect transactions necessary to hedge our obligations under the notes resulting in a commodity hedging disruption event, in which case we may, in our sole and absolute discretion, accelerate your notes. See “— We May Accelerate Your Notes If a Commodity Hedging Disruption Event Occurs” above.

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

Market prices of the commodity futures contracts included in the Index tend to be highly volatile and may fluctuate rapidly based on numerous factors, including changes in supply and demand relationships, governmental programs and policies, national and international monetary, trade, political and economic events, wars and acts of terror, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, weather, and agricultural, trade, fiscal and exchange control policies. The prices of commodities and commodity futures contracts are subject to variables that may be less significant to the values of traditional securities, such as stocks and bonds. These variables may create additional investment risks that cause the value of the notes to be more volatile than the values of traditional securities. As a general matter, the risk of low liquidity or volatile pricing around the maturity date of a commodity futures contract is greater than in the case of other futures contracts because (among other factors) a number of market participants take physical delivery of the underlying commodities. Many commodities are also highly cyclical. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

If an exchange on which the commodity futures contracts underlying the Index are traded increases the amount of collateral required to be posted to hold positions in those futures contracts (i.e., the margin requirements), market participants who are unwilling or unable to post additional collateral may liquidate their positions, which may cause the level of the Index to decline significantly.

The notes are linked in part to the Index, which tracks commodity futures contracts, not physical commodities (or their spot prices). The price of a futures contract reflects the expected value of the commodity upon delivery in the future, whereas the spot price of a commodity reflects the immediate delivery value of the commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and the spot price at a given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity and expectations concerning supply and demand for the commodity. The price movements of a futures contract are typically correlated with the movements of the spot price of the referenced commodity, but the correlation is generally imperfect and price movements in the spot market may not be reflected in the futures market (and vice versa). Accordingly, the notes may underperform a similar investment that is linked to commodity spot prices.

The Index is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts normally specify a certain date for delivery of the underlying physical commodity. As the exchange-traded futures contracts that compose the Index approach expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in August may specify an October expiration. As time passes, the contract expiring in October is replaced with a contract for delivery in November. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “contango,” where the prices are higher in the distant delivery months than in the nearer delivery months, the purchase of the November contract would take place at a price that is higher than the price of the October contract, thereby creating a negative “roll yield.” Contango could adversely affect the level of the Index and thus the value of notes linked to the Index. The futures contracts underlying the Index have historically been in contango.

The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the effect of precluding trading in a particular

PS-5 | Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the level of the Index and, therefore, the value of your notes.

The notes are linked in part to an excess return index and not a total return index. An excess return index, such as the Index, reflects the returns that are potentially available through an unleveraged investment in the contracts composing that index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts.

Accordingly, you will not benefit from any regulatory protections afforded to persons who invest in regulated investment companies or commodity pools.

Each Fund does not fully replicate the performance of its Underlying Commodity due to the fees and expenses charged by the Funds or by restrictions on access to the relevant Underlying Commodity due to other circumstances. Each Fund does not generate any income, and as each Fund regularly sells its Underlying Commodity to pay for ongoing expenses, the amount of its Underlying Commodity represented by each share gradually declines over time. Each Fund sells its Underlying Commodity to pay expenses on an ongoing basis irrespective of whether the trading price of the shares rises or falls in response to changes in the price of its Underlying Commodity. The sale by a Fund of its Underlying Commodity to pay expenses at a time of low prices for its Underlying Commodity could adversely affect the value of the notes. Additionally, there is a risk that part or all of a Fund’s holdings in its Underlying Commodity could be lost, damaged or stolen due to war, terrorism, theft, natural disaster or otherwise. All of these factors may lead to a lack of correlation between the performance of each Fund and its Underlying Commodity. In addition, because the shares of each Fund are traded on a securities exchange and are subject to market supply and investor demand, the market value of one share of each Fund may differ from the net asset value per share of that Fund.

During periods of market volatility, a Fund’s Underlying Commodity may be unavailable in the secondary market, market participants may be unable to calculate accurately the net asset value per share of that Fund and the liquidity of that Fund may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares of a Fund. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of a Fund. As a result, under these circumstances, the market value of shares of a Fund may vary substantially from the net asset value per share of that Fund. For all of the foregoing reasons, the performance of each Fund may not correlate with the performance of its Underlying Commodity as well as the net asset value per share of that Fund, which could materially and adversely affect the value of the notes in the secondary market and/or reduce any payment on the notes.

The investment objective of the SPDR^® Gold Trust is to reflect the performance of the price of gold bullion, less the SPDR^®Gold Trust’s expenses. The price of gold is primarily affected by the global demand for and supply of gold. The market for gold bullion is global, and gold prices are subject to volatile price movements over short periods of time and are affected by numerous factors, including macroeconomic factors, such as the structure of and confidence in the global monetary system, expectations regarding the future rate of inflation, the relative strength of, and confidence in, the U.S. dollar (the currency in which the price of gold is usually quoted), interest rates, gold borrowing and lending rates and global or regional economic, financial, political, regulatory, judicial or other events. Gold prices may be affected by industry factors, such as industrial and jewelry demand as well as lending, sales and purchases of gold by the official sector, including central banks and other governmental agencies and multilateral institutions that hold gold. Additionally, gold prices may be affected by levels of gold production, production costs and short-term changes in supply and demand due to trading activities in the gold market. From time to time, above-ground inventories of gold may also influence the market. It is not possible to predict the aggregate effect of all or any combination of these factors. The price of gold has recently been, and may continue to be, extremely volatile.

The iShares^® Silver Trust seeks to reflect generally the performance of the price of silver, less the iShares^® Silver Trust’s expenses and liabilities. The price of silver is primarily affected by global demand for and supply of silver. Silver prices can fluctuate widely and may be affected by numerous factors. These include general economic trends, technical developments, substitution issues and regulation, as well as specific factors including industrial and jewelry demand, expectations with respect to the rate of inflation,

PS-6 | Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

the relative strength of the U.S. dollar (the currency in which the price of silver is generally quoted) and other currencies, interest rates, central bank sales, forward sales by producers, global or regional political or economic events and production costs and disruptions in major silver-producing countries, such as Mexico, China and Peru. The demand for and supply of silver affect silver prices, but not necessarily in the same manner as supply and demand affect the prices of other commodities. The supply of silver consists of a combination of new mine production and existing stocks of bullion and fabricated silver held by governments, public and private financial institutions, industrial organizations and private individuals. In addition, the price of silver has on occasion been subject to very rapid short-term changes due to speculative activities. From time to time, above-ground inventories of silver may also influence the market. The major end uses for silver include industrial applications, jewelry and silverware. It is not possible to predict the aggregate effect of all or any combination of these factors.

The investment objective of the SPDR^® Gold Trust is to reflect the performance of the price of gold bullion, less the SPDR^®Gold Trust’s expenses, and the iShares^® Silver Trust seeks to reflect generally the performance of the price of silver, less the iShares^® Silver Trust’s expenses and liabilities. The prices of gold and silver are determined by the LBMA or an independent service provider appointed by the LBMA. The LBMA is a self-regulatory association of bullion market participants. Although all market-making members of the LBMA are supervised by the Bank of England and are required to satisfy a capital adequacy test, the LBMA itself is not a regulated entity. If the LBMA should cease operations, or if bullion trading should become subject to a value added tax or other tax or any other form of regulation currently not in place, the role of the LBMA gold and silver prices as a global benchmark for the values of gold and silver may be adversely affected. The LBMA is a principals’ market which operates in a manner more closely analogous to an over-the-counter physical commodity market than regulated futures markets, and certain features of U.S. futures contracts are not present in the context of LBMA trading. For example, there are no daily price limits on the LBMA which would otherwise restrict fluctuations in the prices of LBMA contracts. In a declining market, it is possible that prices would continue to decline without limitation within a trading day or over a period of trading days. The LBMA may alter, discontinue or suspend calculation or dissemination of the LBMA gold and silver prices, which could adversely affect the value of the notes. The LBMA, or an independent service provider appointed by the LBMA, will have no obligation to consider your interests in calculating or revising the LBMA gold and silver prices.

Each Fund is linked to a single commodity and not to a diverse basket of commodities or a broad-based commodity index. Each Fund’s Underlying Commodity may not correlate to the price of commodities generally and may diverge significantly from the prices of commodities generally. As a result, the notes carry greater risk and may be more volatile than notes linked to the prices of more commodities or a broad-based commodity index.

The calculation agent will make adjustments to the Share Adjustment Factor for each Fund for certain events affecting the shares of that Fund. However, the calculation agent will not make an adjustment in response to all events that could affect the shares of the Funds. If an event occurs that does not require the calculation agent to make an adjustment, the value of the notes may be materially and adversely affected.

The notes will not be listed on any securities exchange. Accordingly, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which JPMS is willing to buy the notes. You may not be able to sell your notes. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

You should consider your potential investment in the notes based on the minimums for the estimated value of the notes and the Contingent Digital Return.

The estimated value of the notes is only an estimate determined by reference to several factors. The original issue price of the notes will exceed the estimated value of the notes because costs associated with selling, structuring and hedging the notes are

PS-7 | Structured Investments

Contingent Buffered Digital Notes Linked to the Least Performing of the Bloomberg Commodity Index^SM, the SPDR^® Gold Trust and the iShares^® Silver Trust

included in the original issue price of the notes. These costs include the selling commissions, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. See “The Estimated Value of the Notes” in this pricing supplement.

The internal funding rate used in the determination of the estimated value of the notes is based on, among other things, our and our affiliates’ view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for the conventional fixed-rate debt of JPMorgan Chase & Co. The use of an internal funding rate and any potential changes to that rate may have an adverse effect on the terms of the notes and any secondary market prices of the notes. See “The Estimated Value of the Notes” in this pricing supplement.

We generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. See “Secondary Market Prices of the Notes” in this pricing supplement for additional information relating to this initial period. Accordingly, the estimated value of your notes during this initial period may be lower than the value of the notes as published by JPMS (and which may be shown on your customer account statements).

Any secondary market prices of the notes will likely be lower than the original issue price of the notes because, among other things, secondary market prices take into account our internal secondary market funding rates for structured debt issuances and, also, because secondary market prices (a) exclude selling commissions and (b) may exclude projected hedging profits, if any, and estimated hedging costs that are included in the original issue price of the notes. As a result, the price, if any, at which JPMS will be willing to buy the notes from you in secondary market transactions, if at all, is likely to be lower than the original issue price. Any sale by you prior to the Maturity Date could result in a substantial loss to you.

The secondary market price of the notes during their term will be impacted by a number of economic and market factors, which may either offset or magnify each other, aside from the selling commissions, projected hedging profits, if any, estimated hedging costs and the values of the Underlyings. Additionally, independent pricing vendors and/or third party broker-dealers may publish a price for the notes, which may also be reflected on customer account statements. This price may be different (higher or lower) than the price of the notes, if any, at which JPMS may be willing to purchase your notes in the secondary market. See “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement.

The Index is composed of exchange-traded futures contracts on physical commodities and is designed to be a diversified benchmark for commodities as an asset class. Its component weightings are determined primarily based on liquidity data, which is the relative amount of trading activity of a particular commodity. The Index is an excess return index and not a total return index. An excess return index reflects the returns that are potentially available through an unleveraged investment in the contracts composing the index. By contrast, a “total return” index, in addition to reflecting those returns, also reflects interest that could be earned on funds committed to the trading of the underlying futures contracts. See “Commodity Index Descriptions — The Bloomberg Commodity Indices” in the accompanying underlying supplement.

The SPDR^® Gold Trust is an investment trust sponsored by World Gold Trust Services, LLC. The investment objective of the SPDR^® Gold Trust is for its shares to reflect the performance of the price of gold bullion, less the SPDR^® Gold Trust’s expenses. The SPDR^® Gold Trust holds gold bars. We refer to gold as the Underlying Commodity with respect to the SPDR^® Gold Trust. For additional information about the SPDR^® Gold Trust, see “Fund Descriptions — The SPDR^® Gold Trust” in the accompanying underlying supplement.

The iShares^® Silver Trust is an investment trust sponsored by iShares^® Delaware Trust Sponsor LLC. The iShares^® Silver Trust seeks to reflect generally the performance of the price of silver, less the iShares^® Silver Trust’s expenses and liabilities. The assets of the iShares^® Silver Trust consists primarily of silver held by a custodian on behalf of the iShares^® Silver Trust. We refer to silver as the Underlying Commodity with respect to the iShares^® Silver Trust. For additional information about the iShares^® Silver Trust, see “Annex A” in this pricing supplement.

The following graphs set forth the historical performance of each Underlying based on the weekly historical closing values from January 4, 2013 through March 9, 2018. The closing value of the Index on March 13, 2018 was 87.8767. The closing value of the SPDR^® Gold Trust on March 13, 2018 was $125.78. The closing value of the iShares^® Silver Trust on March 13, 2018 was $15.61. We obtained the closing values above and below from the Bloomberg Professional^® service (“Bloomberg”), without independent verification. The closing values of the Funds above and below may have been adjusted by Bloomberg for actions taken by the Fund, such as stock splits.

The historical closing values of each Underlying should not be taken as an indication of future performance, and no assurance can be given as to the closing value of any Underlying on the Pricing Date or the Observation Date. There can be no assurance that the performance of the Underlyings will result in the return of any of your principal amount.

You should review carefully the section entitled “Material U.S. Federal Income Tax Consequences” in the accompanying product supplement no. 4-I. The following discussion, when read in combination with that section, constitutes the full opinion of our special tax counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of notes.

Based on current market conditions, in the opinion of our special tax counsel it is reasonable to treat the notes as “open transactions” that are not debt instruments for U.S. federal income tax purposes, as more fully described in “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Notes Treated as Open Transactions That Are Not Debt Instruments” in the accompanying product supplement. Assuming this treatment is respected, the gain or loss on your notes should be treated as long-term capital gain or loss if you hold your notes for more than a year, whether or not you are an initial purchaser of notes at the issue price. However, the IRS or a court may not respect this treatment, in which case the timing and character of any income or loss on the notes could be materially and adversely affected. In addition, in 2007 Treasury and the IRS released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary

PS-10 | Structured Investments

income and impose a notional interest charge. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the notes, possibly with retroactive effect. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the notes, including possible alternative treatments and the issues presented by this notice.

Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax (unless an income tax treaty applies) on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities. Section 871(m) provides certain exceptions to this withholding regime, including for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations (such an index, a “Qualified Index”). Additionally, a recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2019 that do not have a delta of one with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on certain determinations made by us, we expect that Section 871(m) will not apply to the notes with regard to Non-U.S. Holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the notes. You should consult your tax adviser regarding the potential application of Section 871(m) to the notes.

Withholding under legislation commonly referred to as “FATCA” may (if the notes are recharacterized as debt instruments) apply to amounts treated as interest paid with respect to the notes, as well as to payments of gross proceeds of a taxable disposition, including redemption at maturity, of a note. However, under a recent IRS notice, this regime will not apply to payments of gross proceeds (other than any amount treated as interest) with respect to dispositions occurring before January 1, 2019. You should consult your tax adviser regarding the potential application of FATCA to the notes.

The estimated value of the notes set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using the internal funding rate described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The estimated value of the notes does not represent a minimum price at which JPMS would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the estimated value of the notes is based on, among other things, our and our affiliates’ view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for the conventional fixed-rate debt of JPMorgan Chase & Co. For additional information, see “Selected Risk Considerations — The Estimated Value of the Notes Is Derived by Reference to an Internal Funding Rate” in this pricing supplement.

The value of the derivative or derivatives underlying the economic terms of the notes is derived from internal pricing models of our affiliates. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the estimated value of the notes is determined when the terms of the notes are set based on market conditions and other relevant factors and assumptions existing at that time.

The estimated value of the notes does not represent future values of the notes and may differ from others’ estimates. Different pricing models and assumptions could provide valuations for the notes that are greater than or less than the estimated value of the notes. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the value of the notes could change significantly based on, among other things, changes in market conditions, our or JPMorgan Chase & Co.’s creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which JPMS would be willing to buy notes from you in secondary market transactions.

The estimated value of the notes will be lower than the original issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the original issue price of the notes. These costs include the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, the projected profits, if any, that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. A portion of the profits, if any, realized in hedging our obligations under the notes may be allowed to other affiliated or unaffiliated dealers, and we or one or more of our affiliates will retain any remaining hedging profits. See “Selected Risk Considerations — The Estimated Value of the Notes Will Be Lower Than the Original Issue Price (Price to Public) of the Notes” in this pricing supplement.

For information about factors that will impact any secondary market prices of the notes, see “Risk Factors — Risks Relating to the Estimated Value and Secondary Market Prices of the Notes — Secondary market prices of the notes will be impacted by many economic and market factors” in the accompanying product supplement. In addition, we generally expect that some of the costs included in the original issue price of the notes will be partially paid back to you in connection with any repurchases of your notes by JPMS in an amount that will decline to zero over an initial predetermined period. These costs can include projected hedging profits, if any, and, in some circumstances, estimated hedging costs and our internal secondary market funding rates for structured debt issuances. This initial predetermined time period is intended to be the shorter of six months and one-half of the stated term of the notes. The length of any such initial period reflects the structure of the notes, whether our affiliates expect to earn a profit in connection with our hedging activities, the estimated costs of hedging the notes and when these costs are incurred, as determined by our affiliates. See “Selected Risk Considerations — The Value of the Notes as Published by JPMS (and Which May Be Reflected on Customer Account Statements) May Be Higher Than the Then-Current Estimated Value of the Notes for a Limited Time Period” in this pricing supplement.

The notes are offered to meet investor demand for products that reflect the risk-return profile and market exposure provided by the notes. See “Hypothetical Payout Profile” and “How the Notes Work” in this pricing supplement for an illustration of the risk-return profile of the notes and “The Underlyings” in this pricing supplement for a description of the market exposure provided by the notes.

The original issue price of the notes is equal to the estimated value of the notes plus the selling commissions paid to JPMS and other affiliated or unaffiliated dealers, plus (minus) the projected profits (losses) that our affiliates expect to realize for assuming risks inherent in hedging our obligations under the notes, plus the estimated cost of hedging our obligations under the notes.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer by notifying the applicable agent. We reserve the right to change the terms of, or reject any offer to purchase, the notes prior to their issuance. In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes, in which case we may reject your offer to purchase.

You should read this pricing supplement together with the accompanying prospectus, as supplemented by the accompanying prospectus supplement relating to our Series A medium-term notes of which these notes are a part, and the more detailed information contained in the accompanying product supplement and the accompanying underlying supplement. This pricing supplement, together with the documents listed below, contains the terms of the notes and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, fact sheets, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in the “Risk Factors” sections of the accompanying product supplement and the accompanying underlying supplement, as the notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the notes.

All information contained in this pricing supplement regarding the iShares^® Silver Trust (the “Silver Trust”), has been derived from publicly available information, without independent verification. This information reflects the policies of, and is subject to change by, iShares^® Delaware Trust Sponsor LLC, a subsidiary of BlackRock, Inc., the sponsor of the Silver Trust. The Bank of New York Mellon is the trustee of the Silver Trust, and JPMorgan Chase Bank, N.A. is the custodian of the Silver Trust. The Silver Trust trades under the ticker symbol “SLV” on NYSE Arca, Inc.

The Silver Trust seeks to reflect generally the performance of the price of silver, less the Silver Trust’s expenses and liabilities. The assets of the Silver Trust consist primarily of silver held by a custodian on behalf of the Silver Trust. The Silver Trust issues shares in exchange for deposits of silver and distributes silver in connection with the redemption of shares. The shares of the Silver Trust are intended to constitute a simple and cost-effective means of making an investment similar to an investment in silver.

The Silver Trust does not engage in any activity designed to derive a profit from changes in the price of silver. The Silver Trust’s only ordinary recurring expense is expected to be the sponsor’s fee, which is accrued daily at an annualized rate equal to 0.50% of the net asset value of the Silver Trust and is payable monthly in arrears. The trustee of the Silver Trust will, when directed by the sponsor of the Silver Trust, and, in the absence of such direction, may, in its discretion, sell silver in such quantity and at such times as may be necessary to permit payment of the Silver Trust sponsor’s fee and of Silver Trust expenses or liabilities not assumed by the sponsor. As a result of the recurring sales of silver necessary to pay the Silver Trust sponsor’s fee and the Silver Trust expenses or liabilities not assumed by the Silver Trust sponsor, the net asset value of the Silver Trust will decrease over the life of the Silver Trust.

Information provided to or filed with the Securities and Exchange Commission (the “SEC”) by the Silver Trust pursuant to the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, can be located by reference to SEC file numbers 333-216971 and 001-32863, respectively, through the SEC’s website at http://www.sec.gov. The Silver Trust is not a mutual fund or any other type of investment company within the meaning of the Investment Company Act of 1940, as amended, and is not subject to regulation thereunder. In addition, the Silver Trust is not a commodity pool within the meaning of the Commodity Exchange Act, as amended, and is not subject to regulation thereunder. For additional information regarding the Silver Trust, the sponsor, the trustee and the custodian, please see the Silver Trust’s prospectus. In addition, information about the Silver Trust may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents and the public website of the Silver Trust maintained by the sponsor at http://us.ishares.com. Information contained in the Silver Trust website is not incorporated by reference in, and should not be considered a part of, this pricing supplement.

The price of silver is primarily affected by global demand for and supply of silver. Silver prices can fluctuate widely and may be affected by numerous factors. These include general economic trends, technical developments, substitution issues and regulation, as well as specific factors including industrial and jewelry demand, expectations with respect to the rate of inflation, the relative strength of the U.S. dollar (the currency in which the price of silver is generally quoted) and other currencies, interest rates, central bank sales, forward sales by producers, global or regional political or economic events and production costs and disruptions in major silver-producing countries, such as Mexico, China and Peru. The demand for and supply of silver affect silver prices, but not necessarily in the same manner as supply and demand affect the prices of other commodities. The supply of silver consists of a combination of new mine production and existing stocks of bullion and fabricated silver held by governments, public and private financial institutions, industrial organizations and private individuals. In addition, the price of silver has on occasion been subject to very rapid short-term changes due to speculative activities. From time to time, above-ground inventories of silver may also influence the market. The major end uses for silver include industrial applications, jewelry and silverware. It is not possible to predict the aggregate effect of all or any combination of these factors.
