Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On August 3, 2026, the Company’s Board of Directors unanimously approved an additional repurchase program authorizing the Company to purchase up to an aggregate of $150 million of the Company’s Class A common stock (the “August 2026 Share Repurchase Program”). This August 2026 Share Repurchase Program is distinct from the existing December 2025 Share Repurchase Program, which, as of the date of this filing, has been fully completed with no authorization remaining. In making the determination that the August 2026 Share Repurchase Program is in the best interest of the Company and its stockholders, the Board of Directors considered a number of factors including, but not limited to, the Company's liquidity and capital allocation strategy, legal and regulatory compliance, the effect of any repurchases on concentration of ownership and voting power, and the effect of any repurchases on any of our periodically reported financial metrics. For the avoidance of doubt, the Board of Directors does not expect that the repurchases contemplated under the August 2026 Share Repurchase Program would result in any stockholder having a majority of voting power. Under the August 2026 Share Repurchase Program, the Company may repurchase shares from time to time through open market purchases, in privately negotiated transactions or by other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Exchange Act, in accordance with applicable securities laws and other restrictions, including Rule 10b-18 under the Exchange Act. The timing and total amount of any stock repurchases will be determined at management's discretion and depend upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices and other considerations. The execution of the repurchase program will be consistent with the Company's capital allocation strategy, which prioritizes investments to grow the business. The share repurchase program has no termination date, and does not obligate Marqeta to acquire a specific number of shares of Class A common stock and may be canceled or suspended at any time without notice.
