For the second quarter of 2026, USDC circulation reached $73.3 billion, a 19% increase from the same period last year. This increase is not isolated, as on-chain transaction volume for USDC also rose substantially, reaching $14.8 trillion - a staggering 151% jump compared to the previous year.

The financial performance of Circle itself has also shown positive trends, with revenue and reserve income totaling $701 million in the quarter, up 7% from the prior year. Adjusted EBITDA for the company was $143 million, representing an 8% increase from a year earlier.
