Coinbase CEO Brian Armstrong posted on X that the agentic economy is not yet priced in, predicting machine-to-machine payments could drive digital dollar demand beyond current estimates. “The agentic economy could be larger than the human economy,” he wrote. The statement reinforces Coinbase’s broader push into AI agent payment infrastructure.
x402 records 75.4M transactions in 30 days
At the center of Armstrong’s thesis is x402, an open payment standard that lets websites and APIs request payment via the HTTP 402 “Payment Required” response — no account setup or API key management needed. Official data shows x402 processed 75.41 million transactions and $24.24 million in volume over the past 30 days, with 94,060 buyers and 22,000 sellers.
In its Q1 2026 earnings call, Coinbase revealed that AI agents use USDC in 99% of on-chain stablecoin transactions, and more than 90% run on Base. Agents are already using x402 for trading, inference, media generation, storage, and other tasks. Coinbase’s Agentic.market — a discovery and payment marketplace for AI agents — had already settled about 165 million transactions at launch, with Base handling 85% of them.
AWS, Stripe, Google Cloud build parallel rails
Large tech firms are moving fast. AWS launched Amazon Bedrock AgentCore Payments in preview, built with Coinbase and Stripe, enabling agents to make stablecoin micropayments via x402 with wallet management, spending limits, and audit logs. Stripe also rolled out x402 payments on Base, allowing agents to pay for APIs, data, and compute with USDC.
Meanwhile, Google Cloud and Solana are building a competing route through Pay.sh, which lets AI agents access Gemini, BigQuery, and Vertex AI APIs using stablecoin payments on Solana. Two parallel infrastructures are emerging, but Armstrong’s bet is clear: agents need internet-native money, and Coinbase is supplying the stack — USDC, Base, x402, and Agentic.market.
The market remains early; many systems are still in preview or limited rollout. Yet transaction data shows agent payments have moved from concept to live usage. If agents start paying micro-amounts for data, compute, and services at internet speed, demand will shift toward fast-settling, dollar-backed digital assets. Armstrong’s claim — that the machine economy isn’t yet priced in — is being tested on-chain, one transaction at a time.
