- →Circle depends on Coinbase for more than half its reported revenue, so the distributor now has unusual power.

Circle's stock fell about 17% by July 4. The trigger was not a hack, a depeg, or a failed product. It was Coinbase joining Open USD on June 30, just weeks before its USDC deal comes up again.
That makes August the real event. Coinbase is not only Circle's biggest distributor. It now sits at the table with a credible replacement stablecoin model behind it. That is the part Circle investors are pricing in.
Crypto Briefing reports that Circle has paid Coinbase more than $908 million in distribution fees under the 2023 agreement. The same report says those fees make up more than half of Circle's total revenue. Under the deal, Coinbase keeps 100% of reserve income from USDC held on Coinbase. It also gets 50% from USDC reserves held elsewhere.
The economics are straightforward. Circle issues USDC, which had about $74 billion in market cap as of July 4, according to Crypto Briefing. Coinbase owns the user relationship. If you hold CRCL shares, your bag depends on what Coinbase accepts in August.
Open USD changes the bargaining math. The consortium has more than 140 members and includes Stripe, BlackRock, Visa, and Mastercard. Its pitch is also pointed: no mint or burn fees, plus majority reserve income sharing with partners by default. That is not just a product launch. It is a term sheet aimed at Circle's model.
This looks like the 1970s money-market fund problem in a new wrapper. Banks had deposits. Funds had the better customer offer. The flow moved because the customer-facing product paid better. Stablecoins are starting to face the same split between issuer control and distribution power.
Circle still has the brand, liquidity, and regulatory track record. USDC is not getting replaced overnight. But the free-money model around reserve income is now officially negotiable. Coinbase does not need Open USD to beat USDC tomorrow. It only needs Open USD to make Circle pay more in August.
Circle's choice to defend USDC as a single-issuer product into August is weak because Coinbase now has Open USD economics to price against it.
By the August 2026 renegotiation, watch whether Coinbase wins more than 50% of off-platform USDC reserve income or starts placing Open USD inside its main app.
