Stablecoins just had their biggest month ever, and it wasn’t particularly close. Adjusted transaction volume hit $1.79 trillion in June 2026, narrowly eclipsing the previous record of $1.78 trillion set back in February.
The headline number is impressive on its own, but the composition underneath tells a more interesting story. Circle’s USDC accounted for roughly 67% of that volume, or about $1.21 trillion. Tether’s USDT, the longtime king of dollar-pegged tokens, managed around 32% with $576 billion.
In English: for every $3 moving through stablecoin rails in June, $2 went through USDC.
The numbers in context
June’s $1.79 trillion represents a 63% jump from May’s $1.1 trillion and a 125% increase compared to the same month last year.
