Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letter of Credit and Restricted Cash In connection with the Oakland lease, the Company is required to provide the landlord a $0.9 million letter of credit. The Company has secured this letter of credit by depositing $0.9 million with the issuing financial institution. This amount is classified as restricted cash and recorded in other assets on the Condensed Consolidated Balance Sheets. As of March 31, 2026, the balance of restricted cash associated with these customer funds was $280.3 million, of which $48.3 million is invested in money market funds. 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. Given the unpredictable nature of legal proceedings, the Company bases its assessment on the information available at the time the financials are available to be issued. As additional information becomes available, the Company reassesses the probability of the loss contingency and the potential liability, and may revise the estimate. The Company is currently involved in the following matters: 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 former Chief Executive Officer, and its Chief Financial Officer (“Defendants”) alleging violations of federal securities laws. The lawsuit asserted that 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 asserted 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. The Securities Actions have been consolidated into one consolidated securities litigation captioned In re Marqeta, Inc. Securities Litigation, Case No. 24-08874-YGR (N.D. Cal) and the Court has appointed a lead plaintiff and lead plaintiff’s counsel in the matter. On April 10, 2025, the lead plaintiff filed a consolidated amended complaint, which alleges a putative class period of between February 28, 2024 and November 4, 2024. The Company and the other Defendants filed a motion to dismiss the consolidated amended complaint on May 15, 2025. On November 3, 2025, a settlement was reached, in principle, with the lead plaintiff’s counsel to resolve the Securities Actions for payments totaling $13.0 million, subject to further documentation and judicial approvals. The Company’s Directors & Officers insurance policy includes a $5.0 million self-insured retention that applies to covered losses related to the Securities Actions, including legal defense fees and settlement payments. If finalized, the settlement will be funded by insurance less the self-insured retention. As of March 31, 2026 and December 31, 2025, the Company had $13.0 million settlement liability in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets. The corresponding insurance recovery receivable was $9.4 million and $9.3 million as of March 31, 2026 and December 31, 2025, respectively, and is recorded in prepaid expenses and other current assets. The receivable reflects the portion of settlement expected to be covered by insurance, determined by applying legal fees incurred through March 31, 2026 toward the self-insured retention. As additional legal fees are incurred beyond this date, they will further reduce the remaining self-insured retention, resulting in a corresponding increase to the receivable balance. On February 4, 2025, a putative shareholder derivative lawsuit, captioned Smith v. Khalaf, et al., Case No. 25-cv-01174 (N.D. Cal.), was filed in the same Court against certain of the Company’s current and former officer and its Board of Directors (as then constituted), and names the Company as a nominal defendant. This lawsuit asserts claims for breach of fiduciary duties and violations of federal securities laws, among other claims, between the time period of May 7, 2024 and November 4, 2024 under similar theories as the Securities Actions. Two other substantially similar putative shareholder derivative lawsuits, captioned Ojserkis v. Khalaf, et al., Case No. 25-cv-01883 (N.D. Cal.) and Preciado v. Khalaf, et al., Case No. 3:25-cv-02100 (N.D. Cal.), were filed on February 21, 2025 and February 27, 2025, respectively. All three putative shareholder derivative suits have been consolidated into one lawsuit captioned In re Marqeta, Inc. Derivative Litigation, Case No. 4:25-cv-01174-YGR (N.D. Cal). The consolidated derivative action is currently stayed pending developments in the consolidated Securities Actions. Settlement of Payment Transactions Pre-funding amounts deposited by program management customers into accounts maintained at Issuing Banks may only be used to settle customers’ payment transactions, and are not subject to the same safeguarding regulations as TransactPay’s customer funds, and as such, are not considered assets of the Company. Accordingly, the funds held in customers’ accounts at Issuing Banks are not reflected on the Company’s Condensed 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. The Company did not incur losses of this nature during the three months ended March 31, 2026 and 2025, respectively. 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 an Issuing Bank for losses such Issuing Bank may incur for non-compliance with applicable laws and regulations, if those losses resulted from the Company’s failure to perform under its program agreement. No significant claims have been incurred during the three months ended March 31, 2026 and 2025. 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. As of March 31, 2026 and December 31, 2025, no demands have been made upon the Company to provide indemnification under such agreements, and the Company is not aware of any claims that could have a material effect on its Condensed Consolidated Financial Statements. The Company also includes service level commitments to its customers, warranting certain levels of performance and permitting these customers to receive credits in the event the Company fails to meet the levels outlined in their respective agreements. No material credits were issued during the three months ended March 31, 2026 and 2025.
