Circle renewed its revenue-sharing agreement with Coinbase on August 5, locking in a distribution model that cost the issuer approximately $908 million in fiscal year 2024. The following day, CoinShares published a research note identifying the Open USD (OUSD) consortium as an existential threat to Circle’s business model.
The friction point is structural. In its Q2 2026 earnings, Circle reported $667.7 million in reserve income — 95.2% of total quarterly revenue. Annualized, that is roughly $2.67 billion. OUSD proposes to redistribute nearly all of that yield to distribution partners, minus a management fee, with zero-fee minting and redeeming. If the model works, the very pool of capital Circle captures today becomes the incentive that draws partners toward a different protocol tomorrow.
OUSD’s 140-Partner Playbook
Open USD was announced June 30, 2026, by Open Standard and CEO Zach Abrams, whose previous company Bridge was acquired by Stripe for $1.1 billion — Stripe’s largest acquisition ever. The consortium counts over 140 firms, including Visa, Mastercard, Stripe, BlackRock, Coinbase, American Express, BNY, Google Cloud, IBM, and Ripple. The reserve-sharing model inverts the issuer-keeps-the-float economics that Circle and Tether have relied on for years. Instead of a single issuer capturing the yield on billions in reserves, the protocol distributes that yield to the partners who drive adoption.
CoinDesk reported August 3 that consortium leaders have taken pains to frame the move as additive rather than combative. Coinbase CEO Brian Armstrong described the exchange as a “multi-stablecoin platform.” Visa CEO Ryan McInerney called Visa “multi-coin, multi-chain.” Mastercard CEO Michael Miebach said OUSD is “another coin that we will enable across our network.”
But the inclusion of Coinbase creates a structural paradox. Coinbase is Circle’s largest distribution partner and collected approximately $908 million in revenue-sharing payments in FY2024 — roughly 54% to 56% of Circle’s total revenue. By joining a consortium designed to redistribute reserve yield across 140 partners, Coinbase is helping build a protocol that commoditizes the exact distribution fee it currently receives from Circle. Bluechip Ratings analyst Amey Dandawate characterized the move as a “free option” for partners. ARK Invest’s Lorenzo Valente said many commitments look like soft letters of intent. Samsung has already disputed its reported participation in the consortium.
The Bear Math
Mizuho downgraded Circle to Underperform on July 14, cutting its price target from $85 to $50. The firm projects 2027 EBITDA at $699 million — 25% below the $930 million consensus. A primary driver: Mizuho expects Circle’s distribution and transaction expense ratio to climb from 64% to 73% as reserve economics face competitive pressure. CRCL shares fell approximately 17.5% on June 30, the day OUSD was announced, extending monthly losses beyond 40%.
Why It Might Not Work
Changing the economics model does not automatically break incumbent network effects. The Paxos Global Dollar Network (USDG) offers a counterexample: a similar yield-sharing structure with 130-plus partners, yet only about $3 billion in circulating supply after 18 months. OUSD is not yet live, has no public supply, and has released no reserve reports. Its success is conditional on execution in the second half of 2026, starting with the Solana blockchain.
The Question Circle’s Renewal Couldn’t Answer
Circle has real defenses — approximately $73 billion in USDC circulation, an OCC federal trust bank charter, a NYDFS charter, and the upcoming launch of the Arc mainnet on September 16. The Coinbase renewal locks in distribution costs for three years through June 2029, buying stability.
But OUSD launches in months. The question the Coinbase renewal could not answer is not whether USDC will maintain its supply — it almost certainly will. The question is whether Circle can continue to capture the income generated by that supply once a protocol exists to redirect it to the partners who move it. The $667.7 million Circle earned this quarter from reserve income is the pool of capital OUSD’s consortium is betting they can share. That is a bet Coinbase just made alongside them.
