140 Firms Just Declared War on Circle

Three days ago, the stablecoin market changed. Not gradually. Not after months of warnings. On Tuesday, a single announcement sent Circle shares down more than 17% in one session and exposed something the financial press is mostly describing wrong.

Here’s what actually happened.

The Real Story Behind Open USD

A coalition of more than 140 companies, including Visa, Mastercard, Stripe, Coinbase, BlackRock, BNY, Standard Chartered, Google, Shopify, and Ripple, announced the formation of Open Standard and a new dollar-pegged stablecoin called Open USD, or OUSD. The stablecoin market has grown to roughly $320 billion as of June 2026, and Citi projects it could reach $1.9 trillion in a base case or as high as $4 trillion in a bull case by 2030. That’s the number Wall Street is citing. The number they’re skipping is more interesting.

Both Circle and Tether park stablecoin backing in short-term U.S. Treasuries and keep the yield themselves. Open USD proposes to share that yield with its distribution network instead. That’s not just a competitive product. That’s a direct attack on the entire economics of the existing business model.

Slight tangent, but it matters: stablecoin aggregate transaction volume hit $33 trillion in 2025, a 72% year-over-year increase, with USDC alone processing $18.3 trillion, more than Visa’s annual payment volume over a comparable period. The infrastructure already works at scale. The question has always been who captures the economics. Tuesday was the answer.

What People Are Missing

Stripe has committed to making OUSD the default stablecoin for businesses on its platform. Visa and Mastercard together touch the majority of global card-based transactions. That’s not a typical competitive threat. Tether and Circle solved the engineering years ago. Their problem was always distribution, getting into the checkout, into the bank’s payment stack, into the merchant’s settlement flow.

That’s precisely what Visa and Mastercard own outright. Visa already runs more than 130 stablecoin-linked card programs across over 50 countries and settles across nine blockchains. They don’t need to build trust. They already are the trust layer.

The part that’s quietly buried: Coinbase, Circle’s single most important distribution partner, is on the OUSD partner list while its $908 million-per-year commercial agreement with Circle comes up for renewal in approximately August 2026, as Circle’s IPO filing disclosed. Think about the timing there. Coinbase has now signed onto a stablecoin explicitly designed to redirect that reserve income stream away from issuers and toward distributors.

Who Benefits. Who Doesn’t.

Circle is the obvious loser in the headline read. CRCL stock opened near $72 on Tuesday and closed down roughly 17.5% to a four-month low, sitting more than 75% below its 52-week peak of around $263. Some analysts called the selloff excessive, and they may have a point about timing. OUSD won’t launch until later in 2026, and as of early July there is no public token contract, confirmed blockchain, or finalized reserve income split among the 140 partners. That’s a well-funded announcement, not a live product yet.

The less obvious winners are the ones nobody is watching yet. JPMorgan, Bank of America, Citigroup, and Wells Fargo, along with several other major banks, announced in early June 2026 that they are building a shared tokenized deposit network through The Clearing House, targeting a first-half-2027 launch. This is not a stablecoin. It is regulated bank money moving on blockchain rails, 24/7, as a direct institutional counter to USDC and USDT. If OUSD normalizes the consortium model, the banks get their entry point without the reputational friction of going it alone.

The deeper implication for traditional finance may be the one that takes longest to fully register. Standard Chartered has warned that stablecoin adoption could drain more than $1 trillion from bank deposits globally, and Citigroup’s analysis projects significant deposit displacement by 2030. That’s not a digital asset story. That’s a banking system restructuring story wearing a crypto headline.

The $320 billion market is just the opening bid.
