Circle Stock Falls 13% as Coinbase, BlackRock Back Rival Open USD Stablecoin

Circle's stock fell 13% Tuesday after Coinbase, BlackRock, Stripe, and more than 100 other firms backed Open USD, a rival stablecoin backed by the Open Standard network. Open USD lets participants retain reserve income and eliminates minting fees, positioning it as an alternative to Circle's USDC.

The Open USD Challenge

Circle's stock declined 13% after the Open Standard unveiled Open USD, a stablecoin backed by more than 100 major institutions including Coinbase, BlackRock, Stripe, and Visa. The new stablecoin's structural model differs from USDC: it allows network participants to retain interest income on reserves and eliminates minting fees entirely, according to CoinDesk reporting.

The backing from Coinbase is particularly significant because the exchange is also a major backer of USDC, Circle's flagship stablecoin. The simultaneous support for both projects suggests institutional preference for optionality in the stablecoin market rather than exclusive backing of a single issuer.

Open USD's Design

Open USD operates through a decentralized network of reserve holders who benefit directly from yield on stablecoin backing, a model that contrasts with Circle's fee-based revenue structure. By eliminating minting fees, the Open Standard aims to reduce friction for integration and give institutional partners greater economic alignment with the stablecoin's success.

The backing from a coalition of payment networks (Stripe, Visa), exchanges (Coinbase), and asset managers (BlackRock) suggests the stablecoin is positioning itself as infrastructure for a multi-issuer ecosystem rather than a single-vendor standard.

Why It Matters

For Traders

Circle's stock volatility signals institutional movement toward alternative stablecoin models; USDC integration risk warrants monitoring for platforms holding large balances.

For Investors

Competition from a reserve-sharing model may pressure Circle's fee revenue; the consortium backing suggests stablecoin commoditization rather than winner-take-all dominance.

For Builders

Multi-stablecoin support is becoming table stakes; protocols should avoid deep coupling to single issuers and prepare migration pathways to Open USD or competing standards.
