Visa and Mastercard have taken equal equity stakes alongside Coinbase, Shopify and Stripe in Open Standard, the consortium behind a new dollar-pegged stablecoin called OUSD that launched on September 30, 2026 with more than $1 billion in liquidity commitments from its five founding partners.

The move positions the world's two largest card networks as co-owners of a payment instrument that, in certain enterprise use cases, could route around their own rails. The five founders hold identical equity positions, and the network behind OUSD expanded from roughly 140 companies at announcement to more than 200 by launch day, according to Open Standard.

What does OUSD actually do differently?

OUSD is live on four blockchains simultaneously: Ethereum, Solana, Base and Tempo. The multichain footprint means corporates do not have to pick a single settlement network to plug into their treasury or payments stack.

Businesses mint OUSD at a one-to-one ratio against US dollars and redeem it the same way. Open Standard charges no fees and imposes no volume limits on either side of the conversion.

Reserves backing each outstanding token sit with BlackRock, BNY and Lead Bank. Open Standard publishes monthly attestations of those reserves, providing holders with recurring verification that the backing dollars are actually in place.

Issuance and redemption run on infrastructure from Bridge, the stablecoin platform now owned by Stripe. Bridge handles the compliance and custody plumbing that determines whether institutional counterparties treat a stablecoin as settlement-grade.

Why are the card networks backing a product that competes with them?

Visa and Mastercard have publicly stated they intend to support multiple stablecoins, not just OUSD, as part of a broader effort to back adoption of the technology and interoperability across platforms.

That hedge is reinforced by Mastercard's acquisition of BVNK, a stablecoin infrastructure provider, completed before OUSD went live. The deal gives Mastercard a parallel capability stack outside the consortium.

By holding equity in OUSD while also running rival bets, Visa and Mastercard are positioning to collect economics whichever token wins, rather than tying their franchise to a single outcome.

How does the economics work for partners?

Most stablecoin issuers generate revenue by holding customer dollars in reserves, typically short-term US government debt, and retaining the interest those reserves earn.

OUSD flips that structure. Founding partners share the majority of reserve earnings, while Open Standard retains a smaller management fee. Stripe has already designated OUSD as its default stablecoin for business transactions.

The yield-sharing arrangement gives distribution partners a direct financial incentive to prefer OUSD over issuers that keep reserve income to themselves. That incentive could pull integrations away from competitors that monetize float exclusively.

What is OUSD up against?

The stablecoin market has crossed $300 billion in total supply, with Tether's USDT and Circle's USDC holding dominant positions. OUSD enters as a heavily distributed challenger rather than a low-fee clone.

Coinbase contributes crypto-native reach, Shopify brings merchants, Stripe brings payment flows, and the two card networks bring relationships with banks and corporates worldwide. The consortium also counts BlackRock and UBS among its broader 200-plus members.

For enterprises, the most immediate operational consequence is optionality. A fee-free, uncapped mint-and-redeem process puts competitive pressure on any provider that charges conversion fees or imposes volume caps.

What metrics should observers track next?

Three indicators will determine whether OUSD's opening position converts into market share: circulating supply against the broader $300 billion-plus field, the share of Stripe's business volume settled in OUSD, and whether Visa's and Mastercard's non-OUSD stablecoin investments scale faster than the consortium token.

A billion dollars in committed liquidity and a 200-partner network form a strong base. The question of whether that base dislodges USDT and USDC will be answered over the next two reporting cycles.
