Open USD is not just another stablecoin announcement. If Visa, Stripe, Coinbase, BlackRock and more than 140 partners actually use it, Circle's reserve-income machine has a real problem.
The stablecoin business has a simple bargain hidden inside it. You hand over dollars, the issuer buys safe assets such as Treasury bills, and the issuer keeps the interest. That bargain has worked very well for Circle and Tether. It looks less comfortable when the payment companies, exchanges and asset managers that create the demand decide they want the yield for themselves.
On Tuesday, June 30, Open Standard announced Open USD, a dollar-backed stablecoin supported by a large group of finance, payments and crypto companies. Barron's reported that the consortium includes Visa, Stripe, Mastercard, Google, IBM, BlackRock, Ripple and Coinbase, with more than 140 businesses signed up. The Wall Street Journal reported that Open USD is slated to be offered later in 2026 on Coinbase-affiliated Base, Solana and other networks.
That detail matters more than the logo wall. A rival stablecoin from a small crypto issuer would be easy for Circle to dismiss. A stablecoin backed by Visa, Mastercard, Stripe, Shopify, Coinbase and BlackRock is a different animal. These are the companies that already sit near the checkout page, the merchant account, the exchange account or the institutional portfolio. If they push Open USD into products people already use, distribution will not be the hard part.
Circle's stock sold off after the announcement, and you don't need a complicated theory to understand why. Barron's reported that Circle traded down nearly 14 percent to $65.39 late Tuesday morning, while Coinbase fell 6 percent to $142.37. Coinbase's presence in the Open USD group is the awkward part. Coinbase has long been tied to USDC economics, yet it is also listed among the supporters of a project built to make stablecoin reserve yield less of a one-company prize.
Circle is exposed because its best business is not mysterious. Investor's Business Daily reported last month that Circle's reserve income rose 17 percent to $653 million in the first quarter of 2026, while USDC in circulation reached $77 billion at quarter-end. That is the engine. More USDC in circulation means more reserves, and more reserves mean more interest income, so long as Circle keeps enough of the market and enough of the economics.
Open USD is aimed straight at that engine. According to Barron's, the new token promises free minting and redemption and revenue-sharing from reserves among adopters. That is not a cosmetic feature. It tells partners that the stablecoin they help distribute should pay them, not simply feed an issuer's income statement. Frankly, that is a cleaner pitch to a platform than asking it to keep sending volume to someone else's Treasury book.
Tether is harder to read in this fight. The Wall Street Journal noted that Tether's USDT and Circle's USDC together command about $260 billion in market capitalization, and Tether remains the larger name by far. But Tether's strength is not the same as Circle's. USDT dominates a heavily offshore, crypto-native market where card networks and U.S. merchant rails are not always the center of gravity. Circle built USDC as the more regulated, institution-friendly dollar token. Open USD is going after that exact lane.
The governance pitch is also sharper than it first looks. If Open USD is governed by a partner consortium rather than one issuer, no single company gets to sit above the ecosystem and keep the main economics for itself. That will appeal to regulated firms that like stablecoins but do not love handing a rival the income stream created by their own customers. You can call that idealism if you want. The better word is leverage.
There are still reasons to be cautious. Big coalitions announce things loudly and integrate them slowly. Open USD is not useful because 140 companies appear in a release. It becomes useful only when those companies put it into checkout flows, wallets, treasury tools, trading products and settlement systems that already move money. The difference between a partner list and a payment network is execution.
The regulatory backdrop is better than it used to be. The Journal reported that stablecoins have become more mainstream since President Trump signed the Genius Act into law last year, creating a framework for dollar-pegged cryptocurrencies. That does not remove every risk, but it does give large financial companies more room to build without pretending stablecoins are still a fringe experiment.
Circle needs an answer before Open USD arrives later this year. It can defend USDC on trust, liquidity, brand and existing integrations, and those are real advantages. But if the companies creating stablecoin demand can also capture more of the reserve yield, loyalty gets expensive fast. The old model worked because the issuer owned the economics. Open USD asks a blunt question: why should the platforms doing the hard distribution accept that deal?
