Circle plunges 17.5% as president sells $30.8M; stablecoin rival looms

Circle's stock tumbled 17.5% to $62.63 on Monday after regulatory filings showed President Heath Tarbert sold $30.8 million in shares since June 2025, adding to pressure from a new stablecoin competitor.

"The market is pricing in two distinct risks: insider selling by a top executive and a credible competitive threat to Circle's core stablecoin business," said Owen Lau, senior analyst at Oppenheimer & Co.

Tarbert completed 10 insider transactions between June 2025 and July 2026, generating about $30.77 million through stock sales and option exercises, according to SEC Form 4 filings. He continues to hold roughly 503,000 CRCL shares and has not disclosed any open-market purchases during the period. The selling comes as CRCL trades well below its post-IPO peak above $260.

The dual shock threatens to further erode investor confidence in Circle's dominance of the stablecoin market, where its USDC token has roughly $73 billion in circulation across 34 blockchains. Open USD, a planned stablecoin backed by more than 140 companies including Visa, Mastercard, Stripe and BlackRock, introduces a revenue-sharing model that analysts say could pressure Circle's margins and increase distribution costs.

Mizuho lowered its price target on CRCL to $50, citing the competitive threat from Open USD's revenue-sharing structure. JPMorgan also reduced earnings forecasts for Circle and Coinbase after a revised USDC revenue-sharing arrangement tied to Hyperliquid balances, saying stronger adoption could result in lower reserve income retained by the companies.

Even as competitive pressure has increased, Circle has continued expanding its regulated infrastructure. The company received final approval from the Office of the Comptroller of the Currency on July 10 to establish Circle National Trust, a federally supervised trust bank that will initially provide digital asset custody, with USDC reserve management planned as a future service.

Tarbert told FOX Business earlier this month that Circle remains focused on building internet financial infrastructure instead of reacting to daily stock movements. He pointed to USDC's native availability across 34 blockchains, arguing those network effects would be difficult for new entrants to reproduce.
