Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries and have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts on our unaudited condensed consolidated balance sheet have been reclassified to conform with our current period presentation.
Consolidation	In the normal course of business, the Company has transactions with various investment entities. In certain instances, the Company provides investment advisory services to pooled investment vehicles, each, a Single Asset Fund ("SAF"). The Company does not have discretion to make any investment, except for the specific investment for which a SAF was formed. The Company performs an assessment to determine (a) whether the Company’s investments or other interests will absorb portions of a variable interest entity’s expected losses or receive portions of the entity’s expected residual returns and (b) whether the Company’s involvement, through holding interests directly or indirectly in the entity would give it a controlling financial interest. The Company consolidates entities in which it, directly or indirectly, is determined to have a controlling financial interest. Consolidation conclusions are reviewed quarterly to identify whether any reconsideration events have occurred. The Company has a majority ownership interest in Forge Europe GmbH ("Forge Europe") and accounts for Forge Europe as a fully consolidated subsidiary. The remaining interest, held by Deutsche Börse Aktiengesellschaft ("DBAG"), is reported as a noncontrolling interest in the unaudited condensed consolidated financial statements. DBAG is a related party of the Company. There have been no changes to the Company's significant accounting policies described in the audited consolidated financial statements for the year ended December 31, 2024, that have had a material impact on these unaudited condensed consolidated financial statements and related notes.
Segment Information	Segment Information The Company operates as a single operating segment and reportable segment. The Company’s chief operating decision maker ("CODM") is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating the Company’s financial performance. Accordingly, we have concluded that we consist of a single operating segment and reportable segment for accounting and financial reporting purposes. The CODM uses net income as the measure of profit or loss for purposes of assessing segment performance and deciding how to allocate resources, primarily by monitoring actual results against the forecast.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such management estimates include, but are not limited to, collectability of accounts receivable, the fair value of financial assets and liabilities, the useful lives of acquired intangible assets and property and equipment, the impairment of long-lived assets and goodwill, the fair value of warrants, equity awards and share-based compensation expenses, including the derived service period for the awards containing market-based vesting conditions, and the valuation of deferred tax assets. These estimates are inherently subjective in nature and, therefore, actual results may differ from the Company’s estimates and assumptions. The Company bases its estimates on historical experience and also on assumptions that it believes are reasonable. Further, the Company applies judgment in determining whether, directly or indirectly, it has a controlling financial interest in the SAFs, in order to conclude whether any of the SAFs must be consolidated. The Company believes the estimates and assumptions underlying the unaudited condensed consolidated financial statements are reasonable and supportable based on the information available as of March 31, 2025. These estimates may change as new events occur and additional information is obtained, and related financial impacts will be recognized in the Company’s unaudited condensed consolidated financial statements as soon as those events become known.
Cash, Cash Equivalents	Cash, Cash Equivalents, and Investments The Company considers all highly liquid investments with original maturities of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist primarily of bank deposit accounts, term deposits (less than 90 days), investments in money market mutual funds, and U.S. government treasury bills.
Investment	The Company's investments consist primarily of term deposits in excess of 90 days, corporate debt securities and U.S. government and agency securities. The Company's debt securities are classified as trading and are reported at fair value, with unrealized gains and losses reported in earnings. Purchase premiums and discounts are amortized or accreted using the effective interest method over the life of the related security and included in interest income in the unaudited condensed consolidated statements of operations.
Goodwill and Other Intangible Assets, Net	Goodwill and Other Intangible Assets, Net Goodwill represents the excess of the aggregate fair value of the consideration transferred in a business combination over the fair value of the assets acquired, net of liabilities assumed. Goodwill is not amortized but tested for impairment annually on October 1, or more frequently if events or changes in circumstances indicate the goodwill may be impaired. The Company has one operating segment and reporting unit, and therefore goodwill is tested for impairment at the entity level. The Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of the reporting unit is less than its carrying value and if so, perform a quantitative test. Events or circumstances that could indicate an impairment include a significant change in the business climate, regulatory environment, established business plans, operating performance indicators, or competition. Potential impairment indicators may also include, but are not limited to, (i) the results of the Company’s most recent annual or interim impairment testing, (ii) downward revisions to internal forecasts, (iii) declines in the Company’s market capitalization below its book value, and the magnitude and duration of those declines, (iv) a reorganization resulting in a change to the Company’s operating segments, and (v) other macroeconomic factors, such as increases in interest rates that may affect the weighted average cost of capital or volatility in the equity and debt markets. If the Company's market capitalization continues to decline or future performance varies from current expectations, assumptions, or estimates, including assumptions related to current macroeconomic uncertainties, this may trigger a future impairment charge. No impairment charges were recognized during the three months ended March 31, 2025 and March 31, 2024, respectively.
Concentration of Credit Risks	Concentration of Credit Risks Financial instruments that potentially subject the Company to concentrations of credit risk primarily comprise cash and cash equivalents and restricted cash, investments, accounts receivable, term deposits, payment-dependent notes receivable, and payment-dependent notes payable. Cash and cash equivalents and restricted cash may, at times, exceed amounts insured by the Federal Deposit Insurance Corporation and the Securities Investor Protection Corporation. The Company performs periodic evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company's investments consist of corporate debt securities and U.S. government and agency securities. The issuers of these debt securities are financially sound and subject to minimal credit risk. The Company has not experienced any losses on its deposits of cash and cash equivalents, restricted cash and investments to date. The Company’s exposure to credit risk associated with its contracts with holders of private company securities (“sellers”) and investors (“buyers”) (sellers and buyers collectively "counterparty" or "client") related to the transfer of private securities is measured on an individual counterparty basis. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, the Company’s exposure is monitored in light of changing counterparty and market conditions.
Comprehensive Loss	Comprehensive Loss Comprehensive loss consists of Net loss and Other comprehensive income or loss. The Company's Other comprehensive income or loss is comprised of foreign currency translation gains and losses. Accumulated other comprehensive loss, as presented in the unaudited condensed consolidated financial statements consists of changes in unrealized gains and losses on foreign currency translation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03 Income Statement- Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to improve financial reporting by requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements of interim and annual reporting periods, including amounts and qualitative descriptions of employee compensation, depreciation, and intangible asset amortization. The standard is effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The standard should be applied prospectively, although retrospective application is permitted. The Company is currently evaluating the impact of adopting ASU 2024-03. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-09 on its financial statements and has not yet determined its transition approach.
