Circle Internet Group, Inc.Coalition including Visa, BlackRock, Alphabet plans Open USD stablecoin, directly threatening Circle's USD Coin.

Circle Internet Group stock fell 44.6% in June 2026, dragged down by Bitcoin's decline and the announcement of a new competitor. The drop included a single-day plunge of 17.6% after a coalition of major companies including Visa, BlackRock, Klarna, Affirm, Alphabet, and Samsung Electronics unveiled plans to launch the Open USD stablecoin later this year, directly threatening Circle's USD Coin, which holds roughly 26% of the stablecoin market. At the same time, Circle's stock was removed from five Russell indexes, reducing passive fund demand. Earlier in the month, Bitcoin's price fell amid economic turbulence and a surprise sale of 0.4% of its holdings by Strategy, the world's largest Bitcoin holder with 843,775 coins, which rattled crypto investors accustomed to the company's accumulation-only stance. Circle remains a major stablecoin issuer, but its competitive moat is under pressure from the well-funded Open USD initiative.
