Coinbase Backs Open USD, Pressuring Circle's USDC Model
Coinbase, USDC's biggest distribution partner, now also backs a rival stablecoin network called Open USD. The move exposes a quiet fight over who earns yield on stablecoin reserves, money that eventually touches every wallet holding these coins.
What actually happened
According to CoinDesk, Circle is defending USDC's economics as competitors offer partners a larger cut of reserve income. Coinbase, long Circle's top USDC partner, is also backing Open USD, a separate stablecoin network, the outlet reported on 17 October 2026. Open USD returns reserve income to partners after subtracting a management fee, unlike arrangements that keep more revenue with the issuer. CoinDesk did not disclose the exact percentage Open USD shares, Circle's current split with Coinbase, or any dollar figures tied to either deal. The report frames this as a distribution battle, with issuers competing to keep exchanges and wallets loyal by promising bigger payouts from reserve asset yield.
How we got here
Stablecoin issuers typically park reserves in low risk assets, such as short term U.S. treasuries, and collect yield on those holdings. Sharing part of that yield with exchanges and wallets has long been standard practice, used to reward partners for driving adoption. Coinbase's distribution reach helped USDC become one of the most used dollar backed tokens. New stablecoin projects are now challenging that arrangement by offering distributors a bigger slice of reserve income, according to CoinDesk, putting pressure on incumbents like Circle to match or lose ground.
Why this matters for you
For everyday holders, nothing changes in the coin itself right now. But the economics behind the scenes could shift fast. If Circle raises its payout to Coinbase, it may trim its own margin or adjust terms elsewhere, including within apps like bonuz that route stablecoin balances. For wallet providers, backing more than one stablecoin network spreads risk and keeps revenue flowing no matter which token wins. For builders, more competing issuers means more leverage to negotiate better terms.
The bigger question
If a major distributor like Coinbase backs two rival stablecoin networks at once, can either issuer hold lasting pricing power? Or does this rivalry eventually squeeze reserve income margins across the whole industry, changing how every stablecoin, including the ones sitting inside everyday wallets, actually generates revenue for the people who hold it?
What to watch
Watch for Circle's formal reply to this competitive pressure, first reported by CoinDesk on 17 October 2026. Watch too for Coinbase or Open USD to publish actual revenue split numbers. Concrete figures from Circle, Coinbase, or Open USD would finally show how much of this reserve income battle reaches ordinary stablecoin users.
