Coinbase CEO Brian Armstrong says AI agents could create an economy bigger than human commerce as machine-to-machine payments move onto crypto rails.
Summary
- Brian Armstrong says machine-to-machine payments could increase demand for digital dollars beyond current estimates.
- x402 saw 75.41 million transactions and $24.24 million in volume over the past 30 days.
- Base and USDC remain central to Coinbase’s plan for payments and AI agent trading.
Armstrong wrote on He added: “The agentic economy could be bigger than the human economy. »
The statement builds on Coinbase’s broader effort in AI agent payments. The company has created payment tools that allow software agents to pay for APIs, data, cloud services and other digital products without a human approving each transaction.
Coinbase has focused on stablecoins because AI agents need payments that run at internet speeds. During its Q1 2026 earnings call, Coinbase said USDC and Base power most on-chain stablecoin transactions for AI agents.
The company also said that AI agents use USDC in 99% of these transactions, while over 90% operate on Base. It says agents are already using x402 for trading, AI, inference, media generation, storage and other tasks.
x402 and core USDC agent base payments
x402 is an open payment standard that allows websites and APIs to request payment via the HTTP 402 “Payment Required” response. The protocol allows customers, applications and AI agents to pay for access without account setup or API key management.
Official x402 data shows 75.41 million transactions and a volume of $24.24 million over the last 30 days. The same dashboard lists 94,060 buyers and 22,000 sellers over this period.
Related coverage from crypto.news reported that Coinbase’s Agentic.market offers AI agents a marketplace to discover and purchase services using USDC via x402. The report states that the platform had already settled around 165 million transactions upon launch.
The same report states that Base processed 85% of 165 million x402 transactions at the time. This gives Coinbase a strong position in the first agent payments market, where low fees and fast settlement are important.
AWS and Google Cloud expand agent payment channels
Big tech companies are also testing agent payments. AWS has launched Amazon Bedrock AgentCore Payments in preview, built with Coinbase and Stripe, to enable agents to make stable micropayments via x402.
AWS said AgentCore Payments allows agents to discover, authorize and execute x402 payments with portfolio management, spending limits and audit logs. He also said that Coinbase developed x402 and built the wallet infrastructure that powers the preliminary payment flows.
Stripe has also launched into the same market. Previous coverage from crypto.news reported that Stripe launched x402 payments on Base, allowing AI agents to pay for APIs, data, and compute with USDC.
Google Cloud and Solana are building a parallel route through Pay.sh. crypto.news reported that Pay.sh allows AI agents to access Gemini, BigQuery and Vertex AI APIs using stable payments on Solana.
AI Agent Economics Puts USDC Demand in Focus
The race to pay AI agents is now becoming a stablecoin story. If agents pay small amounts for data, compute, and services, demand could shift toward fast, dollar-backed digital assets.
Armstrong’s view is that AI agents will need money for the Internet. Coinbase tries to provide this stack via USDC, Base, x402 and Agentic.market.
The market is still early. Many systems remain in preview or limited deployment. Yet transaction figures show that agent payments are moving from concept to actual usage.
