Marqeta and Major Exchange expand stablecoin cards

TLDR

Marqeta has expanded its partnership with Coinbase to let businesses issue payment cards funded directly by stablecoin balances, pushing crypto closer to everyday card payments.

1. Marqeta will handle card issuing and processing while Coinbase custodies stablecoins, converts to fiat, and settles transactions on its Base blockchain.
2. The setup lets companies fund card programs 24/7 and lets users spend stablecoins at millions of existing card-accepting merchants without merchants touching crypto.
3. Fees, supported stablecoins, and rollout timing are still unclear, and competition from Mastercard and others means outcomes will depend on regulation, corridors, and business adoption.

Confidence: high, based on multiple independent reports from October 1617, 2026.

Deep Dive

1. How The MarqetaCoinbase Card Works

Reports say Marqeta and Coinbase are extending their six-year partnership so Marqetas business clients can offer payment cards backed by customers stablecoin holdings. Coinbase will hold the stablecoins, convert between digital assets and traditional currencies, and use its Base layer 2 network for on-chain settlement, while Marqeta issues the cards, runs payment processing, and manages bank and card-network relationships.Marqeta and Coinbase to bring stablecoin-backed cards

Cardholders spend as usual at merchants that already accept card payments, but the funding source is a stablecoin balance that Coinbase turns into fiat behind the scenes. The service targets both crypto-native and non-crypto businesses.

2. Why This Matters For Stablecoin Adoption

The partnership lets businesses load card programs around the clock, independent of bank operating hours, which is a key advantage of blockchain-based settlement. For users, it removes friction: they can keep assets in stablecoins yet still pay at millions of merchants that never integrate crypto directly.

At the same time, Mastercard and BVNK have launched a Global Money Platform that also supports stablecoin-linked cards, with Nuvei and Marqeta among the first planned integrators, showing card networks are racing to embed stablecoins into existing rails.Mastercard connects stablecoins to payment endpoints

For crypto markets, this broadens the real economy use case for assets like USDC and other regulated stablecoins, beyond trading and remittances.

3. What To Watch Next

Key unknowns include which specific stablecoins will be supported, fee structures for businesses and cardholders, and the initial rollout markets and regulatory approvals. Those will determine whether this is mainly an enterprise treasury tool or something that filters down to retail users.

Competition is intensifying as Visa, Mastercard, banks, and other fintechs roll out their own stablecoin payout and card products, so actual adoption will depend on corridor coverage, compliance, and whether businesses see clear cost or speed gains.

Conclusion

Marqeta and Coinbase are turning stablecoin balances into a behind-the-scenes funding layer for standard payment cards, tightening the link between crypto and everyday spending.

If regulatory, cost, and UX pieces fall into place, stablecoins could shift from a niche trading tool into a mainstream payments backbone that users barely notice, while competition among card networks and fintechs shapes which rails win.
