Talos says OpenUSD hits Circle’s reserve economics more than USDC’s 79% onchain share

Circle’s stock fell 17% after the 30 June launch of OpenUSD, the consortium-backed dollar stablecoin supported by more than 140 payments companies and banks, including Stripe, BlackRock and Coinbase. Talos says that reaction may be pricing in a bigger near-term hit to USDC than the onchain data supports.

1. Talos published its analysis in its weekly research report on 15 July 2026, using onchain transfer data for the first half of the year. Its view is straightforward: OpenUSD is more of a challenge to stablecoin reserve income than to USDC’s circulating supply.
2. Under the OpenUSD model, reserve income is redistributed across the partner network instead of being concentrated by Circle. In plain English, that means the new consortium structure pressures Circle’s margins even if it does not quickly pull volume away from USDC.
3. According to Talos, USDC settled around 79% of approximately $38 trillion in adjusted onchain transfer volume in the first half of 2026. That activity spans exchanges, decentralised finance money markets and perpetual futures venues, and Talos says it is reinforced by distribution partnerships with Coinbase and Hyperliquid, plus Circle’s regulatory positioning in US money-transmitter frameworks and its preparation for compliance under the EU’s Markets in Crypto-Assets regulation.
4. Tanay Ved, senior research associate at Talos, said the competitive battle is forming around who earns reserve income, how deeply different stablecoins are embedded in market infrastructure, and the regulatory frameworks around them. His read: OpenUSD is a “consortium-governed shared-yield network” rather than a direct attack on USDC’s existing supply.
5. The broader context is the post-2022 stablecoin market, where the collapse of algorithmic models pushed the industry toward reserve-backed issuers. With reserve rates elevated, who captures the yield has become a commercial question, not just a product design one. On paper, that makes consortium models appealing to distribution partners; in practice, it also means established issuers like Circle are being tested on economics as much as on market share.

Regulation matters here because it shapes which issuers can survive a yield squeeze. In the US, the Clarity for Payment Stablecoins Act has been advancing through Congress, and if passed it would impose reserve, redemption and disclosure requirements that favour established, audited issuers. In Europe, MiCA’s e-money token rules already set reserve and redemption standards that Circle has prepared for, and that any new entrant has to meet as well.
