Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letters of Credit In connection with the Oakland lease, the Company is required to provide the landlord a letter of credit in the amount of $1.5 million. The Company has secured this letter of credit by depositing $1.5 million with the issuing financial institution, and this deposit is classified as Restricted cash in the Consolidated Balance Sheets. Purchase Obligations As of December 31, 2024, the Company had non-cancellable purchase commitments with certain service providers and Issuing Banks of $151.4 million, payable over the next 3 years. These purchase obligations include $138.7 million related to minimum commitments as part of a cloud-computing service agreement. The remaining obligations are related to various service providers and Issuing Banks processing fees over the fixed, non-cancellable respective contract terms. Defined Contribution Plans During the years ended December 31, 2024, 2023, and 2022, the Company contributed a total of $5.0 million, $5.5 million, and $5.8 million to its defined contribution plans, respectively. Legal Contingencies From time to time in the normal course of business, the Company may be subject to various legal matters such as threatened or pending claims or proceedings. As of December 31, 2024 and 2023, there were no legal contingency matters, either individually or in aggregate, that the Company deemed probable that would have a material adverse effect on the Company’s financial position, results of operations, or cash flows. Given the unpredictable nature of legal proceedings, the Company bases its assessment on the information available at the time. As additional information becomes available, the Company reassesses the probability of the loss contingency and the potential liability, and may revise the estimate. On December 9, 2024, a putative securities class action lawsuit, captioned Wai v. Marqeta, Inc., et al., Case No. 24-cv-08874 (N.D. Cal.), was filed in federal court in the Northern District of California (“Court”) against the Company, its Chief Executive Officer, and its Chief Financial Officer (“Defendants”) alleging violations of federal securities laws. The lawsuit asserts that during the putative class period of between August 7, 2024 and November 4, 2024, Defendants made false or misleading statements relating to the Company’s performance or revenue and gross profit expectations in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. On December 10, 2024, a second putative securities class action lawsuit, captioned Ford v. Marqeta, Inc., et al., Case No. 24-cv-08892 (N.D. Cal.), was filed in the same Court against the same Defendants alleging violations of the same federal securities laws. The second lawsuit asserts similar theories of liability as the first lawsuit but alleges a broader putative class period of between May 7, 2024 and November 4, 2024 and some additional and/or different allegations on which the claims are based. Both lawsuits (collectively, the “Securities Actions”) seek to recover damages on behalf of shareholders who acquired shares of the Company’s common stock during their respective putative class periods. Several individuals filed motions to consolidate the Securities Actions and for appointment as lead plaintiff, which are scheduled for a hearing on March 18, 2025. We expect that the Securities Actions will be consolidated and proceed as one lawsuit after the Court appoints a lead plaintiff for the putative class. Given the inherent uncertainty of litigation, the Company cannot reasonably estimate the likelihood of an unfavorable outcome or on the amount or range of any potential loss. The Company and the other Defendants intend to file a motion to dismiss the Securities Actions after the Court-appointed lead plaintiff files a consolidated amended complaint or otherwise designates the operative complaint for the Securities Actions. Settlement of Payment Transactions Generally, customers deposit a certain amount of pre-funding into accounts maintained at Issuing Banks to settle their payment transactions. Such pre-funding amounts may only be used to settle customers’ payment transactions and are not considered assets of the Company. As such, the funds held in customers’ accounts at Issuing Banks are not reflected on the Company’s Consolidated Balance Sheets. If a customer does not have sufficient funds to settle a transaction, the Company is liable to the Issuing Bank to settle the transaction and would therefore incur losses if such amounts cannot be subsequently recovered from the customer. At December 31, 2024 and 2023, we had $7.0 million in Restricted cash which included a deposit held at an Issuing Bank to provide the Issuing Bank collateral in the event that our customers' funds are not deposited at the Issuing Bank in time to settle our customers' transactions with the Card Networks. Indemnifications In the ordinary course of business, the Company enters into agreements of varying scope and terms pursuant to which it agrees to indemnify customers, Card Networks, Issuing Banks, vendors, lessors, and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. With respect to Issuing Banks, the Company has received requests for indemnification from time to time and may indemnify the Issuing Bank for losses the Issuing Bank may incur for non-compliance with applicable law and regulation, if those losses resulted from the Company’s failure to perform under its program agreement with the Issuing Bank. In addition, the Company has entered into indemnification agreements with its directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers, or employees. No demands have been made upon the Company to provide indemnification under such agreements and there are no claims that the Company is aware of that could have a material effect on its Consolidated Balance Sheets, Consolidated Statements of Operations and Comprehensive (Income) Loss, or Consolidated Statements of Cash Flows. The Company also includes service level commitments to its customers warranting certain levels of performance and permitting those customers to receive credits in the event the Company fails to meet those levels.
