Why did CRCL move on Jun 30, 2026?

Circle’s stock (CRCL) plunged 17.5% on June 30, 2026, due to a major competitive threat in the stablecoin market. The sharp decline was triggered by Open Standard's announcement of "Open USD" (OUSD), a rival stablecoin backed by a massive consortium of over 140 prominent companies, including Visa, Mastercard, Stripe, BlackRock, and Coinbase. Investors reacted to fears over Circle's future market share and profitability, as Open USD's fee-free model and yield-sharing structure directly target the enterprise users and reserve interest that drive Circle's core business.
