Stablecoin payments reached an estimated $482 billion in the first nine months of 2026, up 45% from a year earlier, according to Allium's third-quarter report. Circulating stablecoin supply ended September at $305 billion, only 0.4% above its level at the start of the year.

The divergence points to more payment activity without a comparable increase in outstanding tokens. Allium counted 1.04 billion payments, a 71% increase, while the average payment fell from $544 to $462. September recorded $72 billion in payment value, the report's monthly high.

Payment estimates, not raw blockchain volume

The methodology matters. Allium recorded $97.9 trillion in raw stablecoin transfers through September, but classified only $2.4 trillion, or 2.5%, as adjusted end-user activity after screening out exchange, decentralized-finance, infrastructure, automated, and mint-and-burn flows.

Payments represented roughly one-fifth of that adjusted total. Remaining transfers are assigned a single use through ordered classification rules, with payments categorized by whether senders and recipients are consumers or businesses. The figures therefore reflect Allium's classification framework, rather than treating every token transfer as a purchase or remittance.

Smaller payments, concentrated settlement

Tron settled two-thirds of payment value, while USDT accounted for 84%, according to the report. Stablecoin-linked card spending reached $3.9 billion through September, ten times the year-earlier amount, although that remains a small part of overall stablecoin payments.

The findings suggest that circulating supply alone is an incomplete adoption measure. Payment frequency, transaction size, and the distinction between financial-market transfers and end-user payments offer a more specific picture of how stablecoins are being used.
