Chainalysis reports AI agents made over 138 million x402 micropayments on Base

Chainalysis finds AI agents executed over 138 million crypto micropayments via Coinbase's x402 protocol on Base, mostly under 10 cents, with U.S. wallets dominating AI model inference spending.

Why it matters

The data signals growing machine-to-machine commerce on crypto rails, with stablecoins enabling micropayments too small for card networks. The concentration in U.S. wallets for AI inference payments suggests a geographic lead in agentic commerce adoption, though the nature of the underlying economic activity remains debated.

What happened

Blockchain analytics firm Chainalysis reported that autonomous AI agents have made more than 138 million cryptocurrency payments through Coinbase's x402 protocol on the Base network, according to multiple outlets citing the firm's October 2026 North America research. The vast majority of these payments were tiny — over 87% fell between a hundredth of a cent and 10 cents — highlighting stablecoins' role in micropayments. U.S.-linked wallets accounted for 88.1% of geolocated payments for AI model inference, while Chinese-linked wallets represented 0.1%. Transaction volume grew sharply from roughly 1,500 in mid-2025 to over 138 million by Q3 2026, with one source citing 138.5 million and a rise from 58,800 in Q3 2025. The median time between wallet funding and first payment dropped from 73 days to 18 minutes, and wallet refill rates within 30 days rose from 70.6% to 89.3%. Some analysts question whether the volume reflects genuine commercial demand or script-driven activity.
