Stablecoin supply climbed to $303 billion in August 2026, while payment volume for the first eight months of the year rose to between $401 billion and $527 billion, according to a report from blockchain data platform Allium.

Allium said stablecoin supply in August was up 6% from a year earlier. Tether and Circle together accounted for 85% of total supply, underscoring the market’s continued concentration around the two largest issuers.

The report said payment activity accelerated through 2026. From January to August, payment volume increased from $401 billion to $527 billion, equivalent to growth of 42% to 63% from the same period a year earlier. Businesses received between 58% and 64% of those payments, with business-to-business transfers representing the largest segment.

Allium also broke out where stablecoins are being held inside crypto markets. Exchange balances stood at $89 billion, while DeFi protocols held $26 billion. On the payments side, the report said business-related flows included $56 billion for service costs, $43 billion for salaries, $28 billion for supplier payments, and $19 billion for retail purchases. B2B settlement volume ranged from $137 billion to $153 billion.

The report drew a distinction between overall transfer activity and narrower economic usage. Total transfer volume reached $85 trillion from January through August, but Allium estimated actual economic activity at $4 trillion. Transactions represented 69% of that activity mix, while value storage and payments each accounted for as much as 13%. Cross-border stablecoin payments were growing seven times faster than traditional fiat payment networks, the report said.

Why It Matters

The data points to a shift in the stablecoin market from a trading and liquidity tool toward a larger role in payment infrastructure, especially for business settlement. That matters because enterprise and cross-border usage tends to carry different operational and regulatory demands than crypto-native activity, including compliance, treasury management, settlement reliability, and banking access.

The figures also highlight a split that has become more important across digital asset markets: headline transfer volumes can be far larger than economically meaningful usage. For exchanges, issuers, and institutions evaluating stablecoin adoption, that distinction may shape how the sector is measured, regulated, and integrated into broader payment systems.
