Stablecoins spent 2026 getting busier, not bigger. Payment volume hit $482 billion from January through September, up 45% year over year, according to Allium’s latest report.
Total supply barely moved. It rose just 0.4% to $305 billion as of September 30, 2026.
Inside the numbers
Allium’s report, titled “State of Stablecoins and Payments, Q3 2026,” maps where that activity went. September set a monthly record at $72 billion in stablecoin payments.
The third quarter as a whole grew 51% from the same period a year earlier.
Transaction counts outpaced dollar growth. Payments jumped 71% to 1.04 billion transactions over the first nine months of the year.
Meanwhile, the average payment shrank from $544 to $462.
Allium’s data points in that direction. The report highlights business transactions, payroll and cross-border payments as major use cases, with businesses as the main beneficiaries.
Payments made by AI agents doubled to 68.3 million transactions in the third quarter.
The card networks move in
Visa has launched more than 160 stablecoin-linked card programs worldwide. Payment volume on those programs is up nearly 200% year over year.
Visa’s annualized run rate for stablecoin settlements has also passed $20 billion.
Mastercard took a different route: it bought infrastructure. The company’s acquisition of BVNK gives it more direct control over stablecoin payment rails.
Card spending funded by stablecoins grew roughly tenfold to $3.9 billion in the third quarter.
The big issuers stall, the small ones grow
Tether, Circle and Ethena, three of the largest issuers, all saw their supply contract in 2026.
Smaller issuers filled the gap. They added a net $6.9 billion in supply, keeping the overall total roughly level.
What this means
For the crypto market, the most important signal is the split between supply and usage. Supply flatlined, yet payment volume, transaction counts and card spending all climbed sharply.
The competitive picture is less comfortable for the leaders. Contracting supply at Tether, Circle and Ethena, alongside growth at smaller issuers, points to a more fragmented market.
Several things are worth watching from here. One is whether the falling average payment size continues. Another is whether AI-agent transactions keep doubling. The third is whether smaller issuers can sustain their gains once the largest players respond.
