Coinbase and Marqeta expand partnership to launch stablecoin-backed cards for enterprises

The expanded deal pairs Coinbase's custody and Base settlement with Marqeta's card issuing to let businesses spend stablecoins anywhere cards work Coinbase and Marqeta are expanding their partnership to power stablecoin-backed payment cards for enterprise customers. The two companies announced the deal on October 16, 2026. The pitch is simple. A business holds stablecoins, its cardholders swipe at a regular merchant, and the shop never has to know crypto was involved. Stablecoins are tokens built to track the value of a traditional currency. They have spent years as a tool for traders. This deal aims to make them something an accounts payable team might actually use. Coinbase takes custody of the stablecoin balances. It will also handle conversion into fiat currency and run on-chain settlement through Base, its own blockchain.
