USDC has now processed more than $90 trillion in cumulative on-chain transaction volume. To put that number in perspective, it’s roughly four times the annual GDP of the United States, all flowing through a single stablecoin.
Circle announced the milestone on July 7, 2026, pegging the exact figure at $90.8 trillion in lifetime volume. For a token that launched in September 2018, that trajectory from zero to nearly $91 trillion tells a story about where institutional money is actually moving in crypto.
The numbers behind the dominance
In June 2026, adjusted stablecoin transaction volume hit a record $1.79 trillion, according to Visa’s Allium analytics. USDC captured approximately $1.21 trillion of that total, good for roughly 67% of the entire adjusted stablecoin market in a single month.
Zoom out to the first half of 2026, and the picture sharpens further. USDC commanded about 70% of adjusted stablecoin transaction volumes during the period. USDT, long considered the king of stablecoins by market cap, held just 25%.
