Circle revenue rises as USDC transaction volume jumps 151%

Circle reported $701 million in second-quarter 2026 total revenue and reserve income, up 7% year over year, while adjusted EBITDA increased 8% to $143 million and net income reached $48 million, the company said Wednesday.

The stablecoin issuer said USDC in circulation exceeded $73 billion at quarter-end, up 19% year-over-year, while USDC onchain transaction volume surged 151% to $14.8 trillion.

The company said the Circle Payments Network reached $14.7 billion in annualized transaction volume across 175 financial institutions, while its Agent Stack exceeded 900 paid services, with nearly all x402 agent-payment volume settled in USDC.

Circle also outlined major product and institutional milestones. Arc, its new layer 1 blockchain, now has more than 100 builders ahead of its September 16 mainnet launch and will debut with privacy features, AI-powered agent infrastructure, and support for tokenized real-world assets.

The firm announced founding validators including BlackRock, DTCC, Visa, Mastercard, Galaxy, Standard Chartered, ICE, MoneyGram, SBI Group, Sumitomo Corporation, and Global Payments, while confirming that BlackRock’s BUIDL fund and DTCC’s tokenization infrastructure are expected to integrate with the network.

Circle also expanded its USDC adoption through partnerships with BNY, Standard Chartered, Nium, JCB, Grupo Bind, Kakao Group, and Marex during the quarter. Other highlights include regulatory approval to establish Circle National Trust from the US Office of the Comptroller of the Currency and Circle New York Trust from the New York Department of Financial Services.
