Circle faces an existential threat because leaked CLARITY Act text would ban platforms from offering yield on stablecoins, directly or indirectly. Circle earns 96% of its revenue from interest on USDC reserves, and the bill also targets anything economically equivalent to interest, per @NeelMacro citing Eleanor Terrett. No yield on stablecoins means no demand for USDC, and Circle's revenue base evaporates. The stock fell 19% in a session, erasing $5.6B of market value. x.comÂ
