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. On October 15, 2021 (the “Closing Date”), VIH and Bakkt Opco Holdings, LLC (then known as Bakkt Holdings, LLC, “Opco”) and its operating subsidiaries consummated a business combination (the “VIH 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 VIH 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 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 VIH 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. On April 1, 2023 we completed the acquisition of 100% of the ownership interests of Apex Crypto LLC ("Apex Crypto") and subsequently changed the name of the legal entity to Bakkt Crypto Solutions, LLC ("Bakkt Crypto Solutions"), effective June 12, 2023. On March 20, 2024, Bakkt Crypto Solutions merged with and into Bakkt Marketplace, LLC ("Bakkt Marketplace"), with Bakkt Marketplace as the surviving entity in the merger. Bakkt Marketplace was then renamed to Bakkt Crypto Solutions, LLC ("Bakkt Crypto"). Description of Business We provide, or are working to provide, simplified solutions focused in the following areas: Crypto • Custody. Our institutional-grade qualified custody solution is primarily provided by our subsidiary, Bakkt Trust Company LLC (“Bakkt Trust”), a limited purpose trust company that is supervised by the New York State Department of Financial Services (“NYDFS”) and governed by an independent Board of Managers. In connection to the acquisition of Apex Crypto, we acquired third-party custodial relationships with BitGo and Coinbase Custody, which are currently used by Bakkt Crypto for custody and coin transfers, where applicable. In addition, Bakkt Crypto also self-custodies select coins to facilitate consumer withdrawals. Refer to Note 20. • Trading. Our platform provides customers with the ability to buy, sell and store crypto via application programming interfaces or embedded web experience. We enable clients in various industries to provide their customers with the ability to transact in crypto directly in their trusted environments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Our accounting policies are as set forth in the notes to our Annual Report on Form 10-K for the year ended December 31, 2023 (our "Form 10-K"). Basis of Presentation The accompanying unaudited interim consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim consolidated financial statements include the accounts of the Company and our subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In addition, certain reclassifications of amounts previously reported have been made to the accompanying consolidated financial statements in order to conform to current presentation. In the opinion of management, all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation have been included. The interim results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or for any other future annual or interim period. These unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited financial statements and accompanying notes thereto included in our Form 10-K. On April 29, 2024, following approval by our stockholders and Board of Directors, we effected a reverse stock split (the “Reverse Stock Split”) of our Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”), and Class V Common Stock, par value $0.0001 per share (“Class V Common Stock” and collectively with the Class A Common Stock, the “Common Stock”), at a ratio of 1-for-25 (the “Reverse Stock Split Ratio”). Our Class A Common Stock began trading on a reverse-split adjusted basis on the New York Stock Exchange (the "NYSE") as of the open of trading on April 29, 2024. All outstanding warrants and share-based awards were also adjusted on a 1-for-25 basis. As such, the Reverse Stock Split has been retroactively applied to all share and per share information throughout this Quarterly Report on Form 10-Q (unless otherwise noted). Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates and assumptions on historical experience and various judgments that we believe to be reasonable under the circumstances. The significant estimates and assumptions that affect the financial statements may include, but are not limited to, those that are related to going concern, income tax valuation allowances, useful lives and fair value of intangible assets and property, equipment and software, fair value of financial assets and liabilities, determining provision for doubtful accounts, valuation of acquired tangible and intangible assets, the impairment of intangible and long-lived assets and goodwill, our issued warrants, and fair market value of stock-based awards. Actual results and outcomes may differ from management’s estimates and assumptions and such differences may be material to our audited consolidated financial statements. Liquidity and Going Concern The accompanying unaudited consolidated financial statements are prepared on a going concern basis in accordance with U.S. GAAP. This presentation contemplates the realization of assets and the satisfaction of liabilities in the normal course of business and does not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described below. At each reporting period, in accordance with U.S. GAAP, we evaluate whether there are conditions or events that raise substantial doubt about our ability to continue as a going concern within one year after the date the financial statements are issued. In accordance with U.S. GAAP, our initial evaluation can only include management’s plans that have been fully implemented as of the issuance date. Operating forecasts for new products/markets cannot be considered in the initial evaluation as those product/market launches have not been fully implemented. Accordingly, our evaluation entails analyzing prospective fully implemented operating budgets and forecasts for expectations of our cash needs and comparing those needs to the current cash and cash equivalent balances. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, we evaluate whether the mitigating effect of our plans sufficiently alleviates substantial doubt about our ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. Evaluation in conjunction with the issuance of the September 30, 2024 unaudited Consolidated Financial Statements We have incurred net losses and consumed cash flow from operations since our inception and incurred losses and consumed cash through the date of this filing in excess of our cash inflows from operations and fundraising. Due to these ongoing losses and a limited supply of remaining cash and available-for-sale securities, we have been executing a strategic plan to optimize our capital allocation and expense base since the fourth quarter of 2022, which has reduced our annual cash expenses year over year and which we expect will continue to reduce our cash expenses in 2024. As a part of those plans, we have and expect to continue to align headcount and employee-related costs to further reduce cash expenses. This expense restructuring initiative is expected to result in aggregate cash savings of approximately $13.0 million, excluding severance, over the next 12 months. We completed a reduction in force on October 28, 2024 that is expected to result in aggregate cash savings of approximately $3.4 million, excluding severance, over the next 12 months. We expect to enact additional personnel and discretionary spending cuts such as incentive compensation, marketing, professional services and administrative travel to preserve cash to fund operations. It is critical to our plan to mitigate our cash burn that we significantly expand our revenue base to be able to generate a sustainable operating profit. There is significant uncertainty associated with our expansion to new markets and the growth of our revenue base given the uncertain and rapidly evolving environment associated with crypto assets. For the nine months ended September 30, 2024 we incurred a net loss of $63.1 million and consumed $52.6 million of cash in operations. We have historically relied on our existing cash and available-for-sale securities portfolio to fund operations. As of September 30, 2024, we had $29.0 million of available cash and cash equivalents that was not restricted or required to be held for regulatory capital (Note 13) and $6.7 million in available-for-sale securities. We do not have any long-term debt to service but have commitments under long-term cloud computing and lease contracts as described in Notes 14 and 17. We expect to continue to incur losses and consume cash for the foreseeable future. As discussed in Note 8, Opco executed a secured revolving credit facility with Intercontinental Exchange Holdings, Inc. (the “Lender”; the credit facility herein referred to as the “ICE Credit Facility”), with Bakkt and certain subsidiaries of Bakkt as guarantors, which provides the Company with a $40.0 million secured revolving line of credit that matures on December 31, 2026. The $40.0 million ICE Credit Facility is available in defined commitment amounts at specified dates in the future. We believe that our cash, short-term securities and access to the ICE Credit Facility will be sufficient to fund our operations for the next 12 months from the date of these financial statements. Recently Adopted Accounting Pronouncements For the nine months ended September 30, 2024, there were no significant changes to the recently adopted accounting pronouncements applicable to us from those disclosed in Note 2 to the consolidated financial statements included in our Form 10-K. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures , which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard will be effective for our annual periods beginning in fiscal 2024 and interim periods beginning in the first quarter of fiscal 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures , which will require additional tax disclosures, predominantly related to the effective income tax rate reconciliation and income taxes paid. The updated standard will be effective for our annual periods beginning in fiscal 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.

We have one reportable segment to which our revenues relate. Deferred Revenue Contract liabilities consist of deferred revenue for amounts invoiced prior to us meeting the criteria for revenue recognition. We invoice customers for service fees at the beginning of service performance, and such fees are recognized as revenue over time as we satisfy performance obligations. Contract liabilities are classified as “Deferred revenue, current” and “Deferred revenue, noncurrent” in our consolidated balance sheets. The activity in deferred revenue for the nine months ended September 30, 2024 and September 30, 2023 , respectively, was as follows (in thousands): Nine Months Ended Nine Months Ended Beginning of the period contract liability $ 7,480 $ 7,084 Revenue recognized from contract liabilities included in the beginning balance (3,703) (3,055) Increases due to cash received, net of amounts recognized in revenue during the period 826 3,191 End of the period contract liability $ 4,603 $ 7,220 Remaining Performance Obligations As of September 30, 2024, the aggregate amount of the transaction price allocated to the remaining performance obligations related to partially completed contracts is $12.4 million, comprised of $7.8 million of subscription fees and $4.6 million of service fees that are deferred. W e recognize our subscription fees as revenue over a weighted-average period of 19 months (ranges from 2 months to 24 months months) and our service fees as revenue over approximately 45 months. As of September 30, 2023, the aggregate amount of the transaction price allocated to the remaining performance obligations related to partially completed contracts is $20.5 million, comprised of $13.3 million of subscription fees and $7.2 million of service fees that are deferred. We recognize our subscription fees as revenue over a weighted-average period of 29 months (ranges from 1 month to 36 months) and our service fees as revenue over approximately 14 months.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combination and Asset Acquisition	Business Combination and Asset Acquisition Bakkt Crypto On April 1, 2023 we completed the acquisition of 100% of the ownership interests of Bakkt Crypto Solutions. We recognized goodwill from the acquisition due to the assembled, experienced workforce and anticipated growth we expect to achieve from Apex Crypto’s sales pipeline and product capabilities. The total consideration as measured at April 1, 2023 included $55.0 million in cash, approximately $10.5 million in Class A Common Stock payable based on Bakkt Crypto Solutions’ performance in the fourth quarter of 2022, and $11.8 million of cash paid for net working capital, which was predominantly cash held in banks. In addition, we may pay up to $100.0 million of our Class A Common Stock as additional consideration depending on Bakkt Crypto Solutions’ achievement of certain financial targets through 2025 (the "contingent consideration"). As part of the purchase price allocation, the value of the contingent consideration was estimated to be $2.9 million. The following is a reconciliation of the fair value of consideration transferred in the acquisition to the fair value of the assets acquired and liabilities assumed. ($ in millions) Cash consideration paid $ 55.0 Cash paid for working capital and cash 11.8 Class A Common Stock at transaction close 10.5 Estimated fair value of Class A Common Stock contingent consideration 2.9 Total consideration $ 80.2 Current assets $ 31.8 Safeguarding asset for crypto 689.3 Non-current assets 0.3 Intangible assets - developed technology 5.6 Intangible assets - customer relationships 10.2 Goodwill 52.0 Current liabilities (19.7) Safeguarding obligation for crypto (689.3) Net assets acquired $ 80.2 The above fair values are as of the acquisition date. The acquired intangible assets and goodwill required the use of significant unobservable inputs including partner activation forecasts, expectations about customer trading volume and frequency, customer attrition rates, and estimated useful lives of acquired technology and discount rates (level 3 inputs). The acquired customer relationships were valued using a multi-period excess earnings model. The acquired developed technology was valued using a relief from royalty method. Acquired crypto safeguarding asset and obligation were valued based on the midpoint of a bid-ask spread as of the acquisition date (level 2 inputs). Other assets and liabilities were carried over at their acquired costs which was not materially different than their fair values. The contingent consideration payable in Class A Common Stock to Bakkt Crypto Solutions' former owners based on the performance of the business in the 2023 through 2025 annual periods was estimated using a Monte Carlo simulation given the range of possible outcomes. As of December 31, 2023, we determined the value of the contingent consideration was zero, based on our forward-looking projections and minimum profit requirements associated with the contingent consideration and reversed the accrual through acquisition expenses. As of September 30, 2024, we determined the value of the contingent consideration remained zero. The following unaudited pro forma financial information presents the Company's results of operations as if the acquisition of Bakkt Crypto Solutions had occurred on January 1, 2023. The unaudited pro forma financial information as presented below is for illustrative purposes and does not purport to represent what the results of operations would actually have been if the acquisition of Bakkt Crypto Solutions occurred as of the date indicated or what the results would be for any future periods. The unaudited pro forma results reflect the step-up amortization adjustments for the fair value of intangible assets acquired, acquisition-related expenses, and share-based compensation expense for newly issued restricted stock units. Pro forma revenue for the nine months ended September 30, 2023 would be $1,011.0 million. Pro forma net loss for the nine months ended September 30, 2023 would be $148.3 million. Bumped Acquisition On February 8, 2023, we acquired 100% of the units of Bumped Financial, LLC, which we subsequently renamed Bakkt Brokerage, LLC ("Bakkt Brokerage"), a broker-dealer registered with the SEC and the Financial Industry Regulatory Authority, Inc., for cash consideration of $0.6 million. Because of the limited scope of its historical operations, we determined that substantially all of the purchase consideration in the transaction would be allocated to the in-place licenses Bakkt Brokerage held and, as such, have accounted for this transaction as an asset acquisition.

Income Tax Disclosure [Abstract]
Tax Receivable Agreement	Tax Receivable Agreement On October 15, 2021, we entered into a Tax Receivable Agreement (the "TRA") with certain Opco equity holders. Each Opco common unit, when coupled with one share of our Class V Common Stock is referred to as a “Paired Interest.” Pursuant to the TRA, among other things, holders of Opco Common Units may, subject to certain conditions, from and after April 16, 2022, exchange such Paired Interests for Class A Common Stock on a one-for-one basis, subject to the terms of the Exchange Agreement, including our right to elect to deliver cash in lieu of Class A Common Stock and, in certain cases, adjustments as set forth therein. Opco will have in effect an election under Section 754 of the Internal Revenue Code for each taxable year in which an exchange of Opco Common Units for Class A Common Stock (or cash) occurs. The exchanges are expected to result in increases in the tax basis of the tangible and intangible assets of Opco. These increases in tax basis may reduce the amount of tax that we would otherwise be required to pay in the future. These increases in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

Related Parties	Related Parties ICE Credit Facility On August 12, 2024, Bakkt and Opco entered into the ICE Credit Facility, with certain subsidiaries of Bakkt party thereto from time to time, as guarantors, whereby the Lender agreed to provide for a $40.0 million secured revolving line of credit to us for working capital and general corporate purposes. Any borrowings under the facility made prior to December 31, 2024 require the consent of the Lender in its sole discretion. For the period beginning December 31, 2024 through March 30, 2025, Opco can borrow up to an aggregate principal amount (excluding any capitalized interest) of $10.0 million. For the period beginning March 31 through June 29, 2025, Opco can borrow up to an aggregate principal amount (excluding any capitalized interest) of $20.0 million. From the period beginning June 30 through September 29, 2025, Opco can borrow up to an aggregate principal amount (excluding any capitalized interest) of $30.0 million. On or after September 30, 2025, Opco can borrow up to an aggregate principal amount (excluding any capitalized interest) of $40.0 million. As of September 30, 2024, no loans were outstanding under the ICE Credit Facility. Loans under the ICE Credit Facility do not amortize and mature on December 31, 2026. Borrowings under the ICE Credit Facility accrue interest at a rate equal to, at Opco’s election, either the secured overnight financing rate (“SOFR”) for a term of one, three or six months plus 12%, or the prime rate plus 11%. Interest is payable quarterly in arrears with respect to borrowings bearing interest at the prime rate or on the last day of an interest period, but at least every three months, with respect to borrowings bearing interest at the term SOFR rate; provided, that Opco can elect to pay interest in kind by adding such interest amount to the principal amount of the outstanding borrowings under the ICE Credit Facility. For any interest period for which Opco has elected to pay interest in kind, the applicable margin on the outstanding loans will increase by 1% per annum. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the ICE Credit Facility at a per annum rate equal to 2% above the otherwise applicable interest rate. Opco will pay a commitment fee of 0.5% per annum on the daily average of the available commitment that can be borrowed, less the outstanding principal amount of all loans (excluding any capitalized interest). Fees are payable in cash quarterly and at maturity. Loans under the ICE Credit Facility can be prepaid without penalty, subject to customary breakage costs for loans bearing interest at the term SOFR rate. Amounts repaid under the ICE Credit Facility can be reborrowed prior to the maturity date, subject to certain customary conditions set forth in the ICE Credit Facility. The ICE Credit Facility contains customary affirmative and negative covenants, including negative covenants limiting the ability of the Company and its subsidiaries to, among other things, incur debt, grant liens, undergo certain fundamental changes, dispose of assets, make certain restricted payments and prepayments, enter into restrictive agreements, enter into transactions with affiliates, make investments, and amend certain agreements relating to debt, in each case, subject to limitations and exceptions set forth in the ICE Credit Facility. The ICE Credit Facility also contains various customary events of default that include, among others, payment defaults, breach of covenants, inaccuracy of representations and warranties, cross defaults to certain other indebtedness, bankruptcy and insolvency events, judgment defaults, and events constituting a change of control, subject to thresholds and cure periods as set forth in the ICE Credit Facility. The obligations under the ICE Credit Facility are required to be guaranteed by Bakkt and certain material domestic subsidiaries of the Company and secured by substantially all of the personal property of the Company and such subsidiary guarantors.

Other Liabilities Disclosure [Abstract]
Warrants	Warrants As of September 30, 2024 and December 31, 2023, there were 7,140,508 public warrants outstanding. Public warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the public warrant. Holders of public warrants are entitled to purchase one share of Class A Common Stock for every 25 public warrants. The exercise price associated with such warrants is equivalent to $287.50 per share of Class A Common Stock. The public warrants became exercisable on November 15, 2021. The public warrants will expire on October 15, 2026, or earlier upon redemption or liquidation. We may redeem the outstanding warrants when various conditions are met, such as specific stock prices, as detailed in the specific warrant agreements. The warrants are recorded as a liability and reflected as “Warrant liability” in the consolidated balance sheets. During the three and nine months ended September 30, 2024, we received zero and less than $0.1 million, respectively, in proceeds from the exercise of the public warrants. During the three and nine months ended September 30, 2023, we did not receive any proceeds from the exercise of the public warrants. We recognized a gain from the change in fair value of the warrant liability during the three and nine months ended September 30, 2024 of $20.0 million and $13.9 million, respectively. We recognized a gain from the change in fair value of the warrant liability during the three months ended September 30, 2023 of $0.2 million and a loss during the nine months ended September 30, 2023 of $0.9 million. In connection with the Concurrent Offerings (Note 10), we issued and sold to the Third-Party Purchasers (as defined below) an aggregate of 1,396,701 shares of the Company’s Class A Common Stock, including 196,701 shares of Class A Common Stock issued upon exercise of certain of the Pre-Funded Warrants (as defined below) prior to the Third-Party Closing, Class 1 Warrants (“Class 1 Warrants”) to purchase an aggregate of 922,722 shares of Class A Common Stock, Class 2 Warrants (“Class 2 Warrants”) to purchase an aggregate of 922,722 shares of Class A Common Stock and Pre-Funded Warrants (“Pre-Funded Warrants”) to purchase an aggregate of 448,742 shares of Class A Common Stock. Concurrently, under the terms of the ICE Offering we entered into a securities purchase agreement (the “ICE Purchase Agreement” and, together with the Third-Party Purchase Agreement, the “Purchase Agreements”) with ICE, pursuant to which we issued and sold to ICE an aggregate of 461,361 shares of Class A Common Stock, Class 1 Warrants to purchase an aggregate of 230,680 shares of Class A Common Stock, and Class 2 Warrants to purchase an aggregate of 230,680 shares of Class A Common Stock. The consummation of the transactions contemplated by the ICE Purchase Agreement occurred on March 4, 2024 and April 25, 2024. The Class 1 and Class 2 Warrants have an exercise price of $25.50 and have a five-and-a-half year term. The Class 1 and Class 2 Warrants may be exercised at any time after the 6 month anniversary of the relevant closing. The Class 2 warrant agreement contains an alternative exercise clause that entitles the holder to exchange two warrants for a share of stock if certain conditions are met. The Class 1 and Class 2 Warrants issued in the Concurrent Offerings are initially recorded as a liability at fair value and reflected as “Warrant liability” in the consolidated balance sheets. The warrants issued on April 25, 2024 were valued at $2.6 million using the Black-Scholes-Merton model for Class 1 Warrants and a binomial lattice model for the Class 2 Warrants. Prior to the second quarter of 2024, we used a Monte Carlo simulation to measure the fair value of the Class 2 Warrants. During the second quarter of 2024, we adopted a binomial lattice model as our valuation technique as we believe it provides a more accurate and relevant measure of the fair value of the Class 2 Warrants. The Class 1 Warrants and Class 2 Warrants issued on March 4, 2024 were valued at $27.7 million using the Black-Scholes-Merton model for Class 1 Warrants and a Monte Carlo simulation for the Class 2 Warrants. During the three months ended September 30, 2024, Class 2 warrants exercisable for 288,350 shares of Class A Common Stock were exercised under an alternate cashless exercise, resulting in us issuing 144,175 shares of Class A Common Stock. As of September 30, 2024, all Class 1 Warrants and Class 2 Warrants exercisable for 865,050 shares of Class A Common Stock remain outstanding. During the three months ended March 31, 2024, holders exercised all of the Pre-Funded Warrants. The proceeds received from the exercise of Pre-Funded Warrants were immaterial. We recognized a gain from the change in fair value of the warrant liability associated with the Class 1 and Class 2 Warrants during the three and nine months ended September 30, 2024 of $19.4 million and $15.2 million, respectively.

Equity [Abstract]
Stockholders’ Equity	Stockholders’ Equity 2024 Registered Direct Offering On February 29, 2024, we entered into a securities purchase agreement with certain institutional investors (the “Third-Party Purchasers”), pursuant to which we agreed to sell and issue a combination of Class A Common Stock, Class 1 Warrants, Class 2 Warrants and Pre-Funded Warrants in a registered direct offering (the “Third-Party Offering”). In a concurrent registered direct offering (the “ICE Offering” and, together with the Third-Party Offering, the “Concurrent Offerings”) on February 29, 2024, we entered into a securities purchase agreement with ICE (a related party), pursuant to which we agreed to sell and issue a combination of Class A Common Stock, Class 1 Warrants and Class 2 Warrants. We raised net proceeds from the Third-Party Offering of approximately $37.6 million, after deducting the placement agent’s fees and offering expenses payable by us, and raised net proceeds from the ICE Offering of approximately $9.8 million, after deducting offering expenses payable by us. Approximately $2.4 million of proceeds from the ICE Offering were received concurrently with the closing of the Third-Party Offering, with the remaining $7.4 million received in a subsequent closing of the ICE Offering on April 25, 2024 after we obtained stockholder approval for such issuance. We intend to use the net proceeds from the Concurrent Offerings for working capital and other general corporate purposes.

The noncontrolling interest holders' weighted average ownership percentage for the three and nine months ended September 30, 2024 was 53.1% and 56.1%, respectively. Members’ Equity Prior to the VIH Business Combination, Opco had three classes of voting units – Class A, Class B and Class C voting units – and incentive units granted under the Opco Incentive Equity Plan (the “Opco Plan”). In connection with the VIH Business Combination, Class C warrants of Opco ("Class C Warrants") automatically converted into the right to purchase 31,734 Paired Interests in Opco at an exercise price of $126.00 per Paired Interest. Class C Warrants may only be exercised for a whole number of Paired Interests. Holders of Class C Warrants are entitled to purchase one Paired Interest for every 25 Class C Warrants. The Class C Warrants expired on September 23, 2024. As of September 30, 2024, 172,055 Class C Warrants vested but expired unexercised, and the remaining 621,297 Class C Warrants did not vest and expired. No expenses were recorded during the three and nine months ended September 30, 2024 and September 30, 2023, since the service conditions were not probable of being met in those periods.

Share-Based and Unit-Based Comp

Share-Based and Unit-Based Compensation	9 Months Ended

Share-Based Payment Arrangement [Abstract]
Share-Based and Unit-Based Compensation	Share-Based and Unit-Based Compensation 2021 Incentive Plan Our 2021 Omnibus Incentive Plan, as amended (the “2021 Incentive Plan”), became effective on the Closing Date with the approval of VIH’s shareholders and our Board of Directors (the "Board"). The 2021 Incentive Plan allows us to make equity and equity-based incentive awards to employees, non-employee directors and consultants. As of December 31, 2023, there were 2,096,295 shares of Class A Common Stock reserved for issuance under the 2021 Incentive Plan which can be granted as stock options, stock appreciation rights, restricted shares, restricted stock units ("RSUs"), performance stock units ("PSUs"), dividend equivalent rights and other share-based awards. On May 31, 2024, the 2021 Incentive Plan was amended to increase by 938,625 shares the number of authorized shares of Class A Common Stock available for issuance for a new aggregate total of 3,034,920 shares authorized. No award may vest earlier than the first anniversary of the date of grant, subject to limited exceptions. Share-Based Compensation Expense During the three and nine months ended September 30, 2024, we granted 15,756 and 1,044,308 RSUs, respectively, to employees and directors. During the three and nine months ended September 30, 2024, we granted 221,065 PSUs. During the three and nine months ended September 30, 2023, we granted 3,713 and 311,323 RSUs, respectively, to employees and directors. During the three and nine months ended September 30, 2023, we granted zero and 26,945, respectively, PSUs to employees and directors. We recorded $2.4 million and $12.5 million of share-based compensation expense related to RSUs during the three and nine months ended September 30, 2024, respectively. We recorded $2.7 million and $12.1 million of share-based compensation expense related to RSUs during the three and nine months ended September 30, 2023, respectively. We recorded $0.2 million and $0.5 million of share-based compensation expense related to PSUs during the three and nine months ended September 30, 2024, respectively. We recorded $0.3 million and $2.2 million of share-based compensation expense related to PSUs during the three and nine months ended September 30, 2023, respectively. Share-based compensation expense for both RSUs and PSUs, except for share-based compensation expense related to the Company's restructuring efforts discussed below, is included in “Compensation and benefits” in the consolidated statements of operations. Unrecognized compensation expense as of September 30, 2024 and December 31, 2023 was $11.8 million and $14.3 million, respectively, for the RSUs and PSUs. The unrecognized compensation expense as of September 30, 2024 and December 31, 2023 will be recognized over a weighted-average period of 1.59 years and 1.38 years, respectively. RSU and PSU Activity The following tables summarize RSU and PSU activity under the 2021 Incentive Plan for the nine months ended September 30, 2024 and September 30, 2023 (in thousands, except per unit data): RSUs and PSUs Number of RSUs and PSUs Weighted Average Remaining Contractual Term (years) Weighted Average Grant Date Fair Value Aggregate Intrinsic Value Outstanding as of December 31, 2022 551 2.05 $ 101.25 Granted 338 $ 37.25 $ 12,596 Forfeited (145) Vested (211) Outstanding as of September 30, 2023 533 1.57 $ 73.25 Outstanding as of December 31, 2023 521 1.38 $ 69.75 Granted 1,265 $ 13.29 $ 16,816 Forfeited (167) Vested (345) Outstanding as of September 30, 2024 1,274 1.59 $ 13.69 During the three and nine months ended September 30, 2024, we recorded zero and $4.9 million, respectively, of share-based compensation expense related to the accelerated vesting of awards for certain employees, primarily related to the termination of a former executive. Acceleration of share-based compensation expense related to our restructuring efforts is included in “Restructuring expenses” in the consolidated statements of operations. We also recorded reversal of share-based compensation expense of $0.4 million and $0.8 million during the three and nine months ended September 30, 2024, respectively, for forfeitures related to the termination of employees. Reversal of share-based compensation expense related to the Company's restructuring efforts is included in “Restructuring expenses” in the consolidated statements of operations. Total fair value of vested RSU and PSU awards was $0.3 million and $6.8 million for the three and nine months ended September 30, 2024, respectively. Total fair value of vested RSU and PSU awards was $0.1 million and $8.5 million for the three and nine months ended September 30, 2023, respectively. The fair value of the RSUs and PSUs used in determining share-based compensation expense is based on the closing price of our common stock on the grant date. PSUs provide an opportunity for the recipient to receive a number of shares of our Class A Common Stock based on various performance metrics. Upon vesting, each performance stock unit equals one share of Class A Common Stock of the Company. We accrue compensation expense for the PSUs based on our assessment of the probable outcome of the performance conditions. The metrics for PSUs granted during 2022 relate to our performance during fiscal years 2022, 2023 and 2024, as measured against objective performance goals approved by the Board. The actual number of units earned may range from 0% to 150% of the target number of units depending upon achievement of each year's performance goals. PSUs granted in 2022 vest in three equal annual installments, subject to a catch-up provision over the three annual performance targets. The metrics for PSUs granted during 2023 relate to our performance during fiscal year 2023, as measured against objective performance goals approved by the Board. The actual number of units earned may range from 0% to 150% of the target number of units depending upon achievement of the 2023 performance goals. PSUs granted in 2023 vest in three equal annual installments from 2024 to 2026. The metrics for PSUs granted during 2024 relate to our performance during fiscal year 2024, as measured against objective performance goals approved by the Board. The actual number of units earned may range from 0% to 150% or 200% of the target number of units depending on the metric and depending upon achievement of the 2024 performance goals. PSUs granted in 2024 vest in two equal annual installments from 2025 to 2026. Opco Plan Preferred incentive units and common incentive units (collectively, “incentive units”) represent an ownership interest in Opco and are entitled to receive distributions from Opco, subject to certain vesting conditions. Opco classifies incentive units as equity awards on its consolidated balance sheets. Participation units, issued directly by Opco to Opco Plan participants, do not represent an ownership interest in Opco but rather provide Opco Plan participants the contractual right to participate in the value of Opco, if any, through either a cash payment or issuance of Class A Common Stock upon the occurrence of certain events following vesting of the participation units. Refer to Note 11 to our consolidated financial statements included in our Form 10-K where the modifications to the Opco Plan are described in detail. Upon consummation of the VIH Business Combination, the 76,475,000 outstanding preferred incentive units and 23,219,745 outstanding common incentive units were converted into 698,934 common incentive units, and the 10,811,502 outstanding participation units were converted into 1,197,250 participation units. Opco preferred incentive units and common incentive units outstanding prior to the VIH Business Combination, as well as participation units, were not impacted by the Reverse Stock Split discussed in Note 2, therefore these amounts are presented without consideration of the Reverse Stock Split Ratio. Contemporaneously with the conversion, approximately one-third of the awards in the Opco Plan vested. The second tranche vested on the one-year anniversary of the Closing Date and the third tranche vested on the two-year anniversary of the Closing Date, although under the terms of the Opco Plan, employees who were terminated without cause after the Closing Date would vest in the unvested portion of their awards immediately upon their termination date. There has not been, and will not be, any additional awards made under the Opco Plan following the VIH Business Combination. Unit-Based Compensation Expense Unit-based compensation expense for the three and nine months ended September 30, 2023 was as follows (in thousands): Type of unit Three Months Ended Nine Months Ended Common incentive unit $ 372 $ 1,291 Participation unit (32) (4) Total $ 340 $ 1,287 As of December 31, 2023, all Common Incentive Units and Participation Units had vested or been forfeited and there was no unrecognized unit-based compensation expense. Incentive Unit Activity The following table summarizes common incentive unit activity under the Opco Plan for the nine months ended September 30, 2024 (in thousands, except per unit data): Common Incentive Units Number of Common Incentive Units Weighted Average Remaining Contractual Term (years) Weighted Average Grant Date Fair Value Aggregate Intrinsic Value Outstanding as of December 31, 2023 309 0.00 $ 166.75 $ 51,467 Granted — Forfeited — Exchanged (5) Outstanding as of September 30, 2024 304 0.00 $ 166.75 $ 50,677 Common Incentive Units Number of Common Incentive Units Weighted Average Remaining Contractual Term (years) Weighted Average Grant Date Fair Value Aggregate Intrinsic Value Outstanding as of December 31, 2022 332 0.79 $ 157.50 $ 67,635 Granted — Forfeited — Exchanged (8) Outstanding as of September 30, 2023 324 0.54 $ 157.50 $ 65,980 There were no participation units granted during the three and nine months ended September 30, 2023. We did not make any cash payments to settle vested participation units during the three months ended September 30, 2023. We made cash payments of less than $0.1 million to settle vested participation units during the nine months ended September 30, 2023. Determination of Fair Value The fair value of incentive and participation units granted is calculated through a Monte Carlo simulation based on various outcomes. Opco determined that a Monte Carlo simulation was an appropriate estimation model because of the market conditions associated with the vesting of the units. The determination of the fair value of the units is affected by Opco’s stock price and certain assumptions such as Opco’s expected stock price volatility over the term of the units, risk-free interest rates, and expected dividends, which are determined as follows: • Expected term – The expected term represents the period that a unit is expected to be outstanding. • Volatility – Opco has limited historical data available to derive its own stock price volatility. As such, Opco estimates stock price volatility based on the average historic price volatility of comparable public industry peers. • Risk-free interest rate – The risk-free rate is based on the U.S. Treasury yield curve in effect on the grant date for securities with similar expected terms to the term of Opco’s incentive units. • Expected dividends – Expected dividends is assumed to be zero as Opco has not paid and does not expect to pay cash dividends or non-liquidating distributions. • Discount for lack of marketability – an estimated two-year time to exit Predecessor awards and the six-month lock-up restriction on Successor awards is reflected as a discount for lack of marketability estimated using the Finnerty model.

Earnings Per Share [Abstract]
Net Loss per share	Net Loss per share Basic earnings per share is based on the weighted average number of shares of Class A Common Stock issued and outstanding. Diluted earnings per share is based on the weighted average number shares of Class A Common Stock issued and outstanding and the effect of all dilutive common stock equivalents and potentially dilutive share-based awards outstanding. There is no difference in the number of shares used to calculate basic and diluted shares outstanding due to our net loss position. The potentially dilutive securities that would be anti-dilutive due to our net loss are not included in the calculation of diluted net loss per share attributable to controlling interest. The following is a reconciliation of the denominators of the basic and diluted per share computations for net loss (in thousands, except share and per share data): Three Months Ended Three Months Ended Nine Months Ended Nine Months Ended Net Loss per share: Numerator – basic and diluted: Net loss $ (6,291) $ (51,749) $ (63,078) $ (147,119) Less: Net loss attributable to noncontrolling interest (3,398) (34,418) (35,598) (98,964) Net loss attributable to Bakkt Holdings, Inc. – basic and diluted $ (2,893) $ (17,331) $ (27,480) $ (48,155) Denominator – basic and diluted: Weighted average shares outstanding – basic and diluted 6,361,793 3,654,314 5,642,609 3,509,048 Net loss per share – basic and diluted $ (0.45) $ (4.74) $ (4.87) $ (13.72) Potential common shares issuable to employees or directors upon exercise or conversion of shares under our share-based and unit-based compensation plans and upon exercise of warrants are excluded from the computation of diluted earnings per common share when the effect would be anti-dilutive. No shares that are contingently issuable as part of the Bakkt Crypto Solutions acquisition have been included in the calculation of diluted EPS as no amounts are payable as of September 30, 2024.

Commitments and Contingencies	Commitments and Contingencies 401(k) Plan We sponsor a 401(k) defined contribution plan covering all eligible U.S. employees. Both Company and employee contributions to the 401(k) plan are discretionary. For the three and nine months ended September 30, 2024, we recorded approximately $0.5 million and $1.8 million, respectively, of expenses related to the 401(k) plan, which is included in "Compensation and benefits" in the consolidated statements of operations. For the three and nine months ended September 30, 2023, we recorded approximately $0.7 million and $2.4 million, respectively, of expenses related to the 401(k) plan, which is included in "Compensation and benefits" in the consolidated statements of operations. Tax Receivable Agreement The Company is party to a TRA with certain Opco equity holders. As of September 30, 2024, the Company has not recorded a liability under the TRA related to the income tax benefits originating from the exchanges of Opco Common Units as it is not probable that the Company will realize such tax benefits. The amounts payable under the TRA will vary depending upon a number of factors, including the amount, character, and timing of the taxable income of the Company in the future. Should the Company determine that the payment of the TRA liability becomes probable at a future date based on new information, any changes will be recorded on the Company's consolidated statements of operations and comprehensive loss at that time. Litigation As described above, in October 2021, we completed the VIH Business Combination with VIH, pursuant to which VIH changed its name to Bakkt Holdings, Inc. and the current directors and officers of the Company replaced the directors and officers in place prior to the VIH Business Combination. On April 21, 2022, a putative class action was filed against Bakkt Holdings, Inc. and certain of its directors and officers prior to the VIH Business Combination in the U.S. District Court for the Eastern District of New York on behalf of certain purchasers of securities of VIH and/or purchasers of Bakkt Class A Common Stock issued in connection with the VIH Business Combination. On August 3, 2022, the Court appointed lead plaintiffs and lead counsel and on October 18, 2022, lead plaintiffs filed an amended complaint (the "Amended Complaint"). The Amended Complaint alleged that VIH made false or misleading statements and omissions of material fact in the registration statement and prospectus/proxy statement filing in connection with the VIH Business Combination and in other SEC filings made by VIH, in violation of federal securities laws in connection with disclosures relating to certain of VIH’s financial statements, accounting, and internal controls and that, as a result, VIH securities traded at artificially inflated prices. Plaintiffs sought certification of a class of purchasers of (1) VIH/Bakkt’s publicly traded securities between March 31, 2021 and November 19, 2021, and/or (2) Bakkt’s publicly traded securities pursuant and/or traceable to the registration statement. The Amended Complaint sought damages, as well as fees and costs. The Amended Complaint named as defendants only one current director, and no current officers, of Bakkt. On March 14, 2023, the parties reached a settlement in principle. On April 12, 2023, the parties completed a stipulation of settlement resolving the litigation for $3.0 million, subject to Court approval. On September 21, 2023, the Court granted the motion for preliminary approval. On February 27, 2024, the Court held a final approval hearing at which the Court sought certain limited additional information from Plaintiffs, which Plaintiffs provided on March 5, 2024. On April 17, 2024, the Court granted the Plaintiffs' motion for final approval and terminated the class action. We expect the settlement will be covered by our insurance less our contractual retention. On June 23, 2023, an “opt-out” action related to the foregoing class action was filed against Bakkt Holdings, Inc. and the individuals named in the class action. In late February 2024, plaintiff provided notice that he intended to pursue his remedies as a class member, and therefore did not expect further to pursue this action. On March 1, 2024, the parties filed a joint stipulation of dismissal without a settlement or compromise between the parties, and on March 5, 2024 the Court issued an order dismissing the action. On February 20, 2023, a derivative action related to the foregoing class action was filed against Bakkt Holdings, Inc. and all of its directors in the U.S. District Court for the Eastern District of New York. On June 13, 2023, the defendants filed with the Court a pre-motion letter setting forth the reasons for the dismissal of the action. On July 20, 2023, the parties filed with the Court a stipulation of a voluntary dismissal of the action without a settlement or compromise between them. On July 31, 2023, the Court issued an order to dismiss the action. Prior to its acquisition by the Company, Apex Crypto received requests from the SEC for documents and information about certain aspects of its business, including the operation of its trading platform, processes for listing assets, the classification of certain listed assets, and relationships with customers and service providers, among other topics. The SEC has since made a number of follow-up requests for additional documents and information, and the Company has continued to respond to those requests on a timely basis. Based on the ongoing nature of this matter, the outcome remains uncertain and the Company cannot estimate the potential impact, if any, on its business or financial statements at this time. On January 25, 2024, the Company’s subsidiary, Aspire Loyalty Travel Solutions, LLC (“Aspire”) received a letter from one of its vendors alleging breach of its agreement with that vendor relating to a migration of Aspire’s systems to a different vendor. The alleged breach relates to a contractual provision requiring Aspire to originate at least a given percentage of its redemptions on the vendor’s systems. In May 2024, we settled the matter for $1.1 million. We recognized $0.4 million of expense for this matter during the nine months ended September 30, 2024. Other legal and regulatory proceedings have arisen and may arise in the ordinary course of business. However, we do not believe that the resolution of these matters will have a material adverse effect on our financial position, results of operations or cash flows. However, future results could be materially and adversely affected by new developments relating to the legal proceedings and claims. Commercial Purchasing Card Facility On April 7, 2022, we entered into a corporate card services agreement with Bank of America to provide a purchasing card facility that we utilize for redemption purchases made from vendors as part of our loyalty redemption platform. Total borrowing capacity under the facility was $35 million and there is no defined maturity date. Expenditures made using the purchasing card facility are payable at least bi-monthly, are not subject to formula-based restrictions and do not bear interest if amounts outstanding are paid when due and in full. The purchasing card facility requires us to maintain a concentration account with the lender subject to a minimum liquidity maintenance requirement of $7.0 million along with the accounts receivable of our subsidiary, within the loyalty business. Bakkt Holdings, Inc. serves as the guarantor on behalf of our subsidiary under the commercial purchasing card facility. We began using the purchasing card facility in August 2022. In March 2024, Bank of America required us to pledge as collateral the amounts which were previously required to be maintained in the concentration account. In April 2024, Bank of America reduced our credit line associated with the purchasing card facility from $35.0 million to $20.0 million. Purchase Obligations In December 2021, we entered into a four-year cloud computing arrangement which includes minimum contractual payments due to the third-party provider. In December 2023, we agreed to amend the contract and extend the payment period for an additional year. During the year ended December 31, 2023, we entered into a five-year strategic marketing agreement which required a committed spend. In July 2024, we terminated the agreement, which required a settlement payment of $1.1 million and resulted in the release from future obligations. As of September 30, 2024, our outstanding purchase obligations, net of the settlement described above, consisted of the following future minimum commitments (in thousands): Payments Due by Period Less than 1 year 1-3 years 3-5 years More than 5 years Total Purchase obligations $ 5,000 $ 10,500 $ — $ — $ 15,500

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As a result of the VIH Business Combination, the Company acquired a controlling interest in Opco, which is treated as a partnership for U.S. federal income tax purposes, and in most applicable state and local income tax jurisdictions. As a partnership, Opco is not itself subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by Opco is passed through to and included in the taxable income or loss of its partners, including the Company following the VIH Business Combination, on a pro rata basis. The Company's U.S. federal and state income tax expense primarily relates to the Company’s allocable share of any taxable income or loss of Opco following the VIH Business Combination. In addition, Opco’s wholly owned corporate subsidiaries that are consolidated for U.S. GAAP purposes but separately taxed for federal, state, and foreign income tax purposes as corporations are generating federal, state, and foreign income tax expense. Our effective tax rate of 1.8% and less than 1.0% for the three and nine months ended September 30, 2024, respectively, differ from statutory rates primarily due to the loss that is not taxed to the Company and the absence of taxable income to realize the Company's net operating losses and other deferred tax assets. Our effective tax rate of less than 1.0% for the three and nine months ended September 30, 2023, respectively, differ from statutory rates primarily due to the loss that is not taxed to the Company and the absence of taxable income to realize the Company's net operating losses and other deferred tax assets. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Our realizability of our deferred tax assets, in each jurisdiction, is dependent upon the generation of future taxable income sufficient to utilize the deferred tax assets on income tax returns, including the reversal of existing temporary differences, historical and projected operating results and tax planning strategies. As of September 30, 2024 and December 31, 2023 , the Company believed that it was not more likely than not that the net deferred tax assets would be realizable and thus has maintained a full valuation allowance. The effects of uncertain tax positions are recognized in the consolidated financial statements if these positions meet a “more-likely-than-not” threshold. For those uncertain tax positions that are recognized in the consolidated financial statements, liabilities are established to reflect the portion of those positions it cannot conclude “more-likely-than-not” to be realized upon ultimate settlement. The Company had no unrecognized tax benefits or related interest and penalties accrued as of September 30, 2024 or December 31, 2023 .

Fair Value Measurements	Fair Value Measurements Financial assets and liabilities that are measured at fair value on a recurring basis are classified as Level 1, Level 2 and Level 3 as follows (in thousands): As of September 30, 2024 Total Level 1 Level 2 Level 3 Assets: U.S. Treasury debt securities $ 6,727 $ 6,727 $ — $ — Safeguarding asset for crypto 938,695 — 938,695 — Total Assets $ 945,422 $ 6,727 $ 938,695 $ — Liabilities: Safeguarding obligation for crypto 938,695 — 938,695 — Warrant liability - Class 1 and Class 2 warrants 15,193 — — 15,193 Warrant liability - public warrants 643 643 — — Total Liabilities $ 954,531 $ 643 $ 938,695 $ 15,193 As of December 31, 2023 Total Level 1 Level 2 Level 3 Assets: U.S. Treasury debt securities $ 17,398 $ 17,398 $ — $ — Safeguarding asset for crypto 701,556 — 701,556 — Total Assets $ 718,954 $ 17,398 $ 701,556 $ — Liabilities: Safeguarding obligation for crypto $ 701,556 $ — $ 701,556 $ — Warrant liability - public warrants 2,356 2,356 — — Total Liabilities $ 703,912 $ 2,356 $ 701,556 $ — The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivables, unbilled accounts receivables, due from related party, deposits with clearinghouse, due to related party, accounts payable and accrued liabilities, and operating lease obligations approximate their fair values due to their short-term nature. The balance of deposits with clearinghouse not invested in U.S. government securities are in the form of cash, and therefore approximate fair value. Our investments in debt securities consist of U.S. Treasury debt securities held in the custody of a major financial institution. As of September 30, 2024, our investment in available-for-sale debt securities was determined to be a Level 1 investment based on quoted prices in active markets and was recorded in the consolidated balance sheet at fair value. The fair value of the safeguarding obligation for crypto and the corresponding safeguarding asset for crypto was determined using Level 2 inputs which included using the value of the safeguarded asset determined as the mid-point of a bid-ask spread in the market we determined to be the principal market for the related crypto as of September 30, 2024. The contingent consideration associated with the acquisition of Bakkt Crypto Solutions is valued using Level 3 inputs, which includes a Monte Carlo simulation. The inputs for the Monte Carlo simulation included forecasted financial performance of Bakkt Crypto Solutions and estimated earnings volatility. The contingent consideration liability is revalued each reporting period and any change in the liability is reflected in the Company's statements of operations in “Acquisition-related expenses". As of the acquisition date, the fair value of the contingent consideration was estimated to be $2.9 million and used an estimated gross profit volatility of 66%. As of December 31, 2023, we determined the value of the contingent consideration was zero, based on our forward-looking projections and minimum profit requirements associated with the contingent consideration and reversed the accrual through acquisition expenses. As of September 30, 2024, we determined the value of the contingent consideration remained zero. Our public warrant liability is valued based on quoted prices in active markets and is classified within Level 1. Since the second quarter 2024, our Class 1 Warrants and Class 2 Warrants were valued using the Black-Scholes-Merton model and a binomial lattice model, respectively, both of which utilize certain Level 3 inputs. Prior to the second quarter of 2024, our Class 1 Warrants and Class 2 Warrants were valued using the Black-Scholes-Merton model and a Monte Carlo simulation, respectively. A significant input to the Monte Carlo simulation included the volatility of movement in the price of the stock underlying the warrants, which was estimated using the historical volatility of our Class A Common Stock over the contractual period of the warrant. The significant unobservable inputs used for the fair value measurement of our Class 1 Warrants and Class 2 Warrants liabilities as of September 30, 2024 are summarized as follows: Expected term (years) 4.93 - 5.50 Continuous risk-free rate 3.52% - 4.59% Expected volatility 125.0% - 145.0% The preceding methods described may produce fair value calculations that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although we believe our valuation techniques are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Leases [Abstract]
Leases	Leases We lease real estate for office space under operating leases. On December 21, 2023, we signed an agreement to sublease a portion of our corporate headquarters office space in Alpharetta, Georgia. The sublease commenced in March 2024. On March 15, 2023, we signed an amendment to our Scottsdale, Arizona lease that extended the lease term. The amended lease has a term of 89 months and total fixed lease payments over the term of the amended lease are $5.7 million. During the year ended December 31, 2023 , we entered into a new real estate lease for office space in New York, New York, that commenced on January 31, 2022. The lease has a term of 94 months and the total fixed lease payments over the term of the lease are $7.3 million. On April 25, 2022, we signed a lease agreement for call center office space in Alpharetta, Georgia. On May 12, 2022, we executed our option to lease additional space for the Alpharetta call center. The call center lease commenced on June 3, 2022. The lease has a term of 47 months and total fixed lease payments over the term of the lease are $5.9 million. We consider a lease to have commenced on the date when we are granted access to the leased asset. Several of these leases include escalation clauses for adjusting rentals. As of September 30, 2024, we do not have any active finance leases. Our real estate leases have remaining lease terms as of September 30, 2024 ranging from 19 months to 96 months, with three of our leases containing an option to extend the term for a period of 5 years exercisable by us, which we are not reasonably certain of exercising at commencement. None of our leases contain an option to terminate the lease without cause at the option of either party during the lease term. Certain of our real estate leasing agreements include terms requiring us to reimburse the lessor for its share of real estate taxes, insurance, operating costs and utilities which we account for as variable lease costs when incurred since we have elected to not separate lease and non-lease components, and hence are not included in the measurement of lease liability. There are no restrictions or covenants imposed by any of the leases, and none of our leases contain material residual value guarantees. The discount rates for all of our leases are based on our estimated incremental borrowing rate since the rates implicit in the leases were not determinable. Our incremental borrowing rate is based on management’s estimate of the rate of interest we would have to pay to borrow on a fully collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. We have elected the practical expedient under which lease components would not be separated from the non-lease components for all our classes of underlying assets. Accordingly, each lease component and the non-lease components related to the lease component are accounted for as a single lease component. As of September 30, 2024, the weighted average remaining lease term for our operating leases was approximately 78 months, and the weighted average discount rate for our operating leases was 5.3%. As of December 31, 2023, the weighted average remaining lease term for our operating leases was approximately 84 months, and the weighted average discount rate for our operating leases was 5.3%. We were party to short-term leases during the three and nine months ended September 30, 2024, which resulted in less than $0.1 million and less than $0.1 million of rent expense, respectively. We were party to short-term leases during the three and nine months ended September 30, 2023, which resulted in less than $0.1 million and less than $0.1 million of rent expense, respectively.

Investment in Debt Securities	Investment in Debt Securities We have investments in certain debt securities, which we record at fair value and present as "Available-for-sale securities" in the consolidated balance sheets. Unrealized gains and temporary losses, net of related taxes, are included in accumulated other comprehensive income (loss) ("AOCI"). Upon realization, those amounts are reclassified from AOCI to earnings. The amortization of premiums and discounts on the investments are included in our results of operations. Realized gains and losses are calculated based on the specific identification method. We classify our investments as current or noncurrent based on the nature of the investments and their availability for use in current operations. The cost basis and fair value of available-for-sale debt securities with unrealized gains and losses included in “Accumulated other comprehensive loss” in the consolidated balance sheets were as follows (in thousands): September 30, 2024 December 31, 2023 Available-for-sale securities Cost Unrealized Gain, net Fair Cost Unrealized Gain, net Fair Government debt U.S. treasury bonds $ 6,550 $ 177 $ 6,727 $ 17,230 $ 168 $ 17,398 Total available-for-sale securities $ 6,550 $ 177 $ 6,727 $ 17,230 $ 168 $ 17,398 There were no available-for-sale debt securities in an unrealized loss position as of September 30, 2024 or December 31, 2023.

As this process has progressed, we have also worked to find strategic alternatives for Bakkt Trust. As we explore these options, we expect to have a lower regulatory capital requirement during the pendency of this process.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim consolidated financial statements include the accounts of the Company and our subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In addition, certain reclassifications of amounts previously reported have been made to the accompanying consolidated financial statements in order to conform to current presentation. In the opinion of management, all adjustments (consisting of normal recurring accruals), considered necessary for a fair presentation have been included. The interim results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or for any other future annual or interim period. These unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited financial statements and accompanying notes thereto included in our Form 10-K. On April 29, 2024, following approval by our stockholders and Board of Directors, we effected a reverse stock split (the “Reverse Stock Split”) of our Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”), and Class V Common Stock, par value $0.0001 per share (“Class V Common Stock” and collectively with the Class A Common Stock, the “Common Stock”), at a ratio of 1-for-25 (the “Reverse Stock Split Ratio”). Our Class A Common Stock began trading on a reverse-split adjusted basis on the New York Stock Exchange (the "NYSE") as of the open of trading on April 29, 2024. All outstanding warrants and share-based awards were also adjusted on a 1-for-25 basis. As such, the Reverse Stock Split has been retroactively applied to all share and per share information throughout this Quarterly Report on Form 10-Q (unless otherwise noted).
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates and assumptions on historical experience and various judgments that we believe to be reasonable under the circumstances. The significant estimates and assumptions that affect the financial statements may include, but are not limited to, those that are related to going concern, income tax valuation allowances, useful lives and fair value of intangible assets and property, equipment and software, fair value of financial assets and liabilities, determining provision for doubtful accounts, valuation of acquired tangible and intangible assets, the impairment of intangible and long-lived assets and goodwill, our issued warrants, and fair market value of stock-based awards. Actual results and outcomes may differ from management’s estimates and assumptions and such differences may be material to our audited consolidated financial statements.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements For the nine months ended September 30, 2024, there were no significant changes to the recently adopted accounting pronouncements applicable to us from those disclosed in Note 2 to the consolidated financial statements included in our Form 10-K. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures , which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard will be effective for our annual periods beginning in fiscal 2024 and interim periods beginning in the first quarter of fiscal 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures , which will require additional tax disclosures, predominantly related to the effective income tax rate reconciliation and income taxes paid. The updated standard will be effective for our annual periods beginning in fiscal 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our financial statement disclosures.
