The report also found that U.S.-linked wallets accounted for just over 88% of tracked spending on AI models, while China accounted for 0.1%. ## Key takeaways - Chainalysis tracked more than 138 million payments through Coinbase’s x402 protocol by Q3 2026. - The tracked payment count grew from about 1,500 in mid-2025. - U.S.-linked wallets accounted for just over 88% of tracked AI-model payments. - China accounted for 0.1% of tracked AI-model payments. - The report indicates many transactions were tiny, but the provided figures do not give total spending. Coinbase’s x402 protocol recorded more than 138 million payments by AI agents by the third quarter of 2026, according to a new Chainalysis report. The tracked activity rose from about 1,500 payments in mid-2025, showing how quickly software agents are beginning to use crypto to pay for services such as AI models. The number counts payments, not necessarily large transfers: the report’s headline finding is that many transactions were tiny. U.S.-linked wallets dominated the tracked AI-model spending, accounting for just over 88%; China represented 0.1%, according to reporting by CoinDesk. ## What is x402, and what are agents paying for? x402 is a Coinbase-developed protocol that lets websites and services request payment directly from software agents. In practice, an AI agent can pay for a digital service without a person approving each individual transaction. That makes small, automated purchases more practical than relying on conventional payment flows designed around people. This growth builds on a broader push to make agents into paying customers. Coinbase has introduced tools for AI agents to make payments and trade within user-defined limits, while payment companies and crypto firms have backed x402 as a possible standard. Earlier x402 reporting cited 75 million payments and $24 million in volume for one month; those figures are a different time window and should not be treated as directly comparable to Chainalysis’s cumulative count. ## What does the U.S. lead tell us? The geographic split is striking: U.S.-linked wallets made more than eight out of every ten tracked AI-model payments, compared with China’s 0.1%. That describes the activity Chainalysis tracked, not the overall use of AI or crypto in either country. The figures alone also don’t explain why the U.S. share is so high. For everyday users, the important shift is that AI services may increasingly be bought in tiny, automated increments rather than through a person choosing a subscription or entering card details. That could make pay-per-use services easier, but it also means users need to understand what limits an agent has before allowing it to spend. Watch for clearer controls around spending caps, permissions, and the services an agent can pay. The scale of x402 activity is notable alongside [Coinbase’s tools for agent-led payments and trading](/articles/2026-06-12-coinbase-launches-ai-powered-crypto-trading-and-payment-tool) and [new business support for accepting x402 payments](/articles/2026-07-23-coinbase-enables-corporate-payments-from-ai-agents-via-x402-protocol). The payment count shows substantial transaction activity, but by itself does not establish how much users spent in total or whether the model is sustainable. ## FAQ ### What is Coinbase’s x402 protocol? x402 is a Coinbase-developed protocol that lets websites and services request payments from software agents, including AI agents, for digital services. ### How many payments did AI agents make through x402?
