What is Open USD, the 140-company stablecoin?

On the day Open USD was announced, the market did something telling: it sold off the incumbent, not the newcomer. Circle’s stock fell roughly 16% before Open USD had a single user. The reason is one design choice, and it has almost nothing to do with the coin itself.

What is Open USD, in one sentence?

Open USD (ticker OUSD) is a dollar-backed stablecoin, a digital coin worth one dollar and backed one-to-one by real dollar reserves, launched on June 30, 2026 by a group of more than 140 companies. What sets it apart is not the dollar peg, which it shares with every other stablecoin. It is who gets paid, and who decides.

A stablecoin issuer holds your dollars, parks them in safe assets like US Treasuries, and keeps the interest. On more than $300 billion of stablecoins in circulation, that interest is a very large number. Open USD proposes to hand most of it back to the businesses that actually move the coin, and to let those businesses govern the coin together rather than answer to a single issuer.

Who is actually behind it?

Open USD is run by Open Standard, an independent company with a board drawn from its partners. Its founding CEO is Zach Abrams, who co-founded the stablecoin infrastructure firm Bridge, bought by Stripe in 2024. The partner list is the headline: more than 140 companies, including Visa, Mastercard, American Express, Stripe, BlackRock, Coinbase, BNY, Standard Chartered, U.S. Bank, BBVA, Google, Shopify, IBM, Solana, Polygon and Ripple.

Seeing Visa, Mastercard and American Express on the same list is the surprise. These are companies that spend most of their lives competing. Getting them to back one piece of shared plumbing is either the whole point or the whole problem, depending on who you ask.

What is genuinely new here?

Three rules, and they all point the same way:

• No fees to mint or redeem, at any size. Turning dollars into OUSD and back costs nothing, with no volume caps. Most issuers charge for this at scale.
• The interest goes to the distributors. Most of the income earned on the reserves flows back to the companies that adopt and distribute OUSD, minus a small management fee, instead of staying with the issuer.
• Everyone at the table governs it. Design and reserve policy are set by the partner board, not by one company’s roadmap.

Christian Catalini, the MIT economist who helped design Facebook’s abandoned Libra currency, put the logic bluntly in Forbes: issuing a stablecoin does not earn you anything beyond the distribution you already bring. If that is true, then a coin that pays distributors for the volume they generate is simply pricing the thing correctly, and the single-issuer model is leaving money on the table.

Why did Circle’s stock drop?

Because Circle’s business is the model Open USD is built to undercut. USDC, Circle’s coin, has around $73 billion in circulation; Tether’s USDT leads the market at roughly $145 billion. Both keep the reserve interest. A rival that gives that interest away, backed by the very networks Circle needs as distributors, is a direct threat to how it makes money, which is why the shares fell about 16% on the announcement.

It is worth staying level-headed. Several analysts called the sell-off an overreaction, noting that USDC has years of liquidity, integrations and regulatory groundwork a launch deck does not. They point to a cautionary precedent: Global Dollar, another consortium-backed coin, has reached only about $3 billion against USDC’s $73 billion. Circle’s CEO Jeremy Allaire said the company welcomes “continued innovation and competition in the space.” A promise from 140 logos is not the same as a coin people use.

Where will Open USD run?

On several public networks, the shared ledgers these coins live on. Open USD is set to launch natively on Solana first, with Stellar, Base (Coinbase’s network), Polygon and others to follow. It will also be issued natively on Tempo, the new payments-focused chain, from day one. The strategy is deliberately the opposite of exclusivity: be everywhere, so no single chain or wallet owns the standard.

The hard part: can 140 rivals share one steering wheel?

This is where the honest doubts live. The last big stablecoin consortium, Centre, was run by Circle and Coinbase and was quietly wound down in 2023, after which Circle took full control of USDC. Coordinating two partners was hard. Coordinating 140, many of whom compete head to head, is a different order of difficulty.

Meng Liu, a senior analyst at Forrester, named the tension precisely: “A consortium model can create neutrality. It can also create slow decision-making.” She called Open USD “an important signal, not yet a proven network.” Omid Malekan, who teaches at Columbia Business School, was blunter, calling it the “logo spray and pray” phase: putting your name on a list is easy, changing your business model is hard.

There is a legal question too. New US stablecoin rules under the GENIUS Act restrict paying interest to coin holders. Open USD does not pay holders; it pays distributors. But US regulators have already proposed extending that ban to affiliates and third parties, not just issuers, aimed squarely at reserve income routed this way. Whether the distinction holds is not yet settled, and the whole revenue model rests on the answer.

Why it matters

Strip away the logos and Open USD is an argument about where the money in digital dollars should go: to whoever issues the coin, or to whoever moves it. That argument was always coming. When Visa and Mastercard started settling transactions in stablecoins, the coin stopped being the product and became plumbing, and plumbing competes on cost, reach and neutrality, not brand.

The same reserve-and-settle mechanics these giants are standardizing are already what lets a group of friends settle a shared tab in seconds, across borders, with their money staying in their own wallets, on Spliz: free to track, 0.1% only when the group actually settles. The infrastructure fight at the top and the everyday use at the bottom are the same story, seen from two ends.

The one-line version

Open USD is not trying to build a better dollar. It is trying to change who keeps the interest on it, and whether 140 competitors can share a steering wheel is the question that decides if it works.

The coin is the easy part. Getting rivals to agree on how it runs is the whole bet.
