Visa, Mastercard, BlackRock & Coinbase Launch Open USD Stablecoin, Challenging Circle's USDC Dominance

140+ companies.

One stablecoin.

Zero warning for Circle.

On June 30, 2026, the biggest consortium in crypto history announced Open USD — a US dollar-pegged stablecoin issued by a new entity called Open Standard.

The lineup reads like someone copy-pasted the Forbes 500:

Visa. Mastercard. Stripe. BlackRock. Coinbase. BNY Mellon. Google. American Express. Klarna. Chime. Ripple.

That's not a startup. That's the entire financial system deciding to build its own money layer.

What actually is Open USD?

The structure of Open USD is what makes it dangerous — not just for Circle, but for every existing stablecoin model.

Here's how it works:

Zero-fee minting and redemption — any partner can mint or burn OUSD without paying a fee. No limits on volume.Reserve income shared with partners — the interest earned on the reserves backing OUSD gets distributed back to distributing partners, minus a small management fee.Open governance — the company is collectively owned by ecosystem participants, not a single issuer

That last point is the nuclear move.

USDC works like this: Circle holds the reserves. Circle earns the interest. Circle keeps the money.

Open USD inverts that completely. The 140+ partners are the economics. They distribute the stablecoin and get paid from the float for doing it.

The CEO of Open Standard is Zach Abrams — co-founder of Bridge, the Stripe-owned stablecoin infrastructure company that Stripe acquired for $1.1 billion. This man knows how stablecoin plumbing works at the deepest level.

Why this changes everything

Stablecoin economics are simple. Whoever holds the reserves earns yield on them. When interest rates are at 4-5%, holding $70 billion in US treasuries as USDC reserves earns Circle roughly $3.5 billion a year in pure float income.

That's the entire business model. Mint stablecoin → hold reserves → collect yield → profit.

Open USD doesn't destroy this model.

It redistributes it.

Instead of Circle collecting $3.5B and sharing none of it... the 140 partners collectively earn from the float they help grow.

Why would Visa choose to distribute USDC — which earns Circle money — when it could distribute Open USD and earn a cut of the reserves itself?

That's the question that sent Circle's stock down 17.5% in a single session.bitget

The bigger context: This was inevitable

In November 2024, Paxos launched USDG — the Global Dollar Network — with Mastercard, Robinhood, and Kraken as participants. Same model. Reserve sharing. Collective governance.

Open USD is USDG scaled to maximum aggression.

And neither Tether nor Circle was invited to the party.

Tether's CEO Paolo Ardoino's response was... "Welcome OUSD. Player 2 has entered the game."

Tether thinks they're fine. Maybe they are. USDT has $186 billion in circulation and barely blinked.

Circle? Different story.

What doesn't exist yet

Open USD has not launched.

The consortium announced the token. The blockchain it runs on? Not disclosed yet. The actual minting infrastructure? Still being built. The regulatory approvals? Still in process.

This is an announcement of intent, not a product you can hold today.

But the market reaction to an unborn token dropping Circle 17% tells you everything about how seriously the industry is taking this.

Here is my POV:

The reserve-sharing model is the future of stablecoin distribution. If you're building any DeFi protocol, payment infrastructure, or wallet — you need to think about which stablecoin earns you money for distributing it. That calculus just changed completely. OUSD isn't a stablecoin. It's a distribution network with a dollar token attached.
