Coinbase Global (COIN) surged 11.3% after the exchange operator joined a coalition of more than 140 payment, financial and technology firms, including Visa and Mastercard, to launch a new dollar stablecoin called Open USD (OUSD).

The initiative, organized under an entity called Open Standard, positions OUSD as a jointly governed stablecoin rather than one controlled by a single issuer. Structurally, that is a departure from the model Coinbase has used with Circle on USDC. Reported design features include zero-fee minting and redemption, plus a mechanism to distribute reserve income across the participating partners rather than concentrating it with one issuer. For a company whose USDC-related revenue depends heavily on interest earned on reserves, sharing that income stream with a broad coalition is a tradeoff analysts are still parsing.
