Circle's $USDC’s Grip on Solana Slips to 46% as $USDT and Rivals Gain Ground

Circle's $USDC now accounts for just 46% of Solana's stablecoin supply, its lowest share in more than 2 years.

According to DefiLlama data, $USDC's share has fallen to 46.13%, while $USDT's share has risen to 16.42%. Other stablecoins now collectively account for more than 26% of Solana's stablecoin market, highlighting broader liquidity diversification across the network.

Drift Fallout Changed Community Sentiment

The shift follows the April 1 Drift exploit, which sparked widespread criticism of Circle across the Solana ecosystem. After attackers reportedly moved more than $230M via Circle's Cross Chain Transfer Protocol (CCTP), many ecosystem participants urged DeFi users to swap $USDC for $USDT. Critics argued that Circle should have frozen the stolen funds.

When challenged on the decision, Circle CEO Jeremy Allaire said the company would not intercept funds without legal precedent, describing the situation as a "moral quandary." Meanwhile, Tether earned goodwill across parts of the Solana community after supporting Drift during its recovery efforts, strengthening $USDT's standing among many users.

Fresh Legal Challenges Add to Pressure

Circle now faces renewed scrutiny following a July 8 report by the International Consortium of Investigative Journalists. According to the report, law enforcement authorities in Wisconsin and New York accused Circle of refusing to assist in freezing or recovering $USDC linked to scams. Wisconsin prosecutors filed a criminal complaint alleging that Circle failed to comply with a court order requiring the recovery of stolen assets.

Although the complaint involves a single misdemeanor count, former FBI financial crime expert Karen Greenway noted that criminal charges against a major financial firm are highly unusual.

Circle rejected the allegations, calling the complaint meritless. The company argued that it lacked the technical ability to comply with the order and maintained that the Wisconsin court lacked jurisdiction.

Stablecoin issuers such as Circle also face pressure from a changing regulatory landscape. Polymarket now places the odds of the CLARITY Act passing in 2026 at 40%, down from 82% in February.

Senator Cynthia Lummis recently warned that failure to pass the CLARITY Act could delay meaningful U.S. stablecoin legislation until 2030, turning what could have been a 1-year delay into a 4-year setback.

Solana's Stablecoin Economy Continues to Expand

The decline in $USDC's market share comes even as Solana's stablecoin economy continues to grow at a record pace. During the first half of 2026, Solana recorded $1.12T in peer-to-peer stablecoin volume, up 72%, alongside 83.6M peer-to-peer transactions, up 37%. Active wallets reached an all-time high of 4.3M.

Retail transfers between $100 and $1,000 totaled a record $13.5B. Institutional transfers above $20,000 reached $1.07T, while micropayments between $0.50 and $100 climbed to an all-time high of $1.50B.

Circle has continued to expand its infrastructure despite a decline in market share. Gateway, launched in July 2025 and integrated with Solana in January 2026, allows users and businesses to access a unified $USDC balance across supported blockchains without manual bridging or third-party liquidity. The stablecoin giant recently reported that lifetime Gateway volume has now surpassed $4.5B.

Circle Scores a Major Regulatory Win

Despite mounting competitive and legal challenges, Circle recently secured one of its biggest regulatory milestones. The U.S. Office of the Comptroller of the Currency granted final approval for Circle to establish Circle National Trust, a national trust bank operating as First National Digital Currency Bank, N.A.

The approval strengthens $USDC infrastructure through federally regulated custody, with reserve management planned as a future capability, while placing Circle's trust operations under direct federal oversight.

Investors welcomed the development, sending Circle's stock, $CRCL, more than 15% higher to around $71 following the announcement before retracing to its current price of $66.

While $USDC remains Solana's largest stablecoin by a wide margin, its share has fallen below 50% for the first time in more than 2 years. With growing competition, evolving regulation, and changing community sentiment, the battle for stablecoin dominance on Solana appears far from over.
