Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Organization VPC Impact Acquisition Holdings (“VIH”) was a blank check company incorporated as a Cayman Islands exempted company on July 31, 2020. VIH was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. VIH’s sponsor was VPC Impact Acquisition Holdings Sponsor, LLC (the “Sponsor”). The registration statement for VIH’s Initial Public Offering was declared effective on September 22, 2020. On September 25, 2020, VIH consummated the Initial Public Offering of 20,000,000 units (the “Units”), generating gross proceeds of $200.0 million. Simultaneously with the closing of the Initial Public Offering, VIH consummated the sale of 6,000,000 warrants (the “private placement warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to the Sponsor, generating gross proceeds of $6.0 million. On September 29, 2020, the underwriters notified VIH of their intention to partially exercise their over-allotment option on October 1, 2020. As such, on October 1, 2020, VIH consummated the sale of an additional 737,202 Units, at $10.00 per Unit, and the sale of an additional 147,440 private placement warrants, at $1.00 per Private Warrant, generating total gross proceeds of $7.5 million. Following the closing of the Initial Public Offering on September 25, 2020 and the partial exercise of the underwriter’s over-allotment on October 1, 2020, an amount of approximately $207.4 million ($10.00 per Unit) from the proceeds of the sale of the Units in the Initial Public Offering and the sale of the private placement warrants, net of transaction costs, was placed in a trust account (the “Trust Account”). On October 15, 2021 (the “Closing Date”), VIH and Bakkt Opco Holdings, LLC and its operating subsidiaries (f/k/a Bakkt Holdings, LLC, “Opco”) consummated a business combination (the “Business Combination”) contemplated by the definitive Agreement and Plan of Merger entered into on January 11, 2021 (as amended, the “Merger Agreement”). In connection with the finalization of the Business Combination, VIH changed its name to “Bakkt Holdings, Inc.” and changed its jurisdiction of incorporation from the Cayman Islands to the State of Delaware (the “Domestication”). Unless the context otherwise provides, “we,” “us,” “our,” “Bakkt”, the “Company” and like terms refer (i) prior to the Closing Date, to Opco and its subsidiaries and (ii) after the Closing Date, to Bakkt Holdings, Inc. and its subsidiaries, including Opco. Immediately following the Domestication, we became organized in an umbrella partnership corporation, or “up-C,” structure in which substantially all of our assets and business are held by Opco, and our only direct assets consist of common units in Opco (“Opco common units”), which are non-voting interests in Opco, and the managing member interest in Opco. In connection with the Business Combination, a portion of VIH shares were exchanged for cash for shareholders who elected to execute their redemption right. The remaining VIH shares were exchanged for newly issued shares of our Class A common stock. Additionally, all outstanding membership interests and rights to acquire membership interests in Opco were exchanged for Opco common units and an equal number of newly issued shares of our Class V common stock. The existing owners of Opco other than Bakkt are considered noncontrolling interests in the accompanying consolidated financial statements (the “financial statements”). Refer to Note 4 for further discussion on the Business Combination. Our Class A common stock and warrants are listed on the New York Stock Exchange under the ticker symbols “BKKT” and “BKKT WS,” respectively. Description of Business We offer a platform with three complementary aspects - a digital asset marketplace, a loyalty redemption service, and an alternative payment method. Digital Asset Marketplace. Our digital asset marketplace enables participants to seamlessly transact in a growing universe of digital assets and has applications for individual consumers, businesses and institutions. Through Bakkt Trust Company LLC (“Bakkt Trust”), we have an institutional-grade custodian for bitcoin and ether. Bakkt Trust is a New York limited-purpose trust company that is chartered by and subject to the supervision and oversight of the New York Department of Financial Services (“NYDFS”). In September 2019, Bakkt Trust, along with ICE Futures U.S., Inc. (“IFUS”) and ICE Clear US, Inc. (“ICUS”), both of which are wholly-owned subsidiaries of ICE, brought to market an institutional-grade, regulated infrastructure for trading, clearing, and custody services for bitcoin. Bakkt Trust acts as a qualified custodian for bitcoin, which enables Bakkt Trust to offer end-to-end regulated, physically-delivered bitcoin futures and options contracts to financial institutions and market makers. In addition, Bakkt Trust offers non-trading- related, standalone custody of bitcoin and ether to institutions and certain high net worth individuals in cryptoassets, subject to NYDFS regulatory oversight. Loyalty Redemption. Our loyalty redemption service, an institutional-grade loyalty platform born out of our acquisition of Bridge2 Solutions in February 2020 (Note 4), provides seamless and cost-effective options for consumers to use their loyalty points. Our loyalty redemption platform, which is cloud-based and delivered through major web browsers and mobile devices, connects loyalty programs to leading commerce partners allowing consumers to redeem a spectrum of loyalty currencies for merchandise, services and gift cards. Alternative Payments. Our alternative payments platform provides choice and convenience to both consumers and merchants. Through Bakkt Marketplace, LLC (“Bakkt Marketplace”), we have an integrated platform that enables consumers and enterprises to transact in digital assets. Alternative payments users have a digital wallet that enables them to purchase, sell, convert, and or spend digital assets. Users can also use their digital wallet to spend fiat currency with various retailers and convert loyalty and rewards points into fiat currency. We have received money transmitter licenses from all states throughout the U.S. where such licenses are required, have obtained a New York State virtual currency license, and are registered as a money services business with the Financial Crimes Enforcement Network of the United States Department of the Treasury. Bakkt Trust’s custody solution provides support to Bakkt Marketplace with respect to bitcoin and ether functionality within the consumer app.
