Coinbase CEO Brian Armstrong stated that autonomous systems will soon drive a larger economy than human activity. He pointed to the rapid deployment of payment infrastructure designed for machines across major technology firms. He also highlighted rising transaction volumes and increasing reliance on blockchain-based payments for automated systems.
Armstrong shared this outlook as companies accelerate tools that enable machines to transact without traditional financial identifiers. He stated that systems now operate without passports, cards, or bank accounts, and instead rely on blockchain networks. He also emphasized that Coinbase’s Base network supports a growing share of these automated transactions.
The agentic economy will be larger than the human economy.
And it’s happening on Base. https://t.co/HuIx1whFPp

Coinbase Expands Infrastructure for AI Agents Transactions
Coinbase introduced new platforms to support machine-based commerce, including Agentic.market and the x402 payment protocol. These tools allow AI agents to discover services and complete transactions independently using blockchain networks. Armstrong stated, “Cryptocurrency is the only viable form of money for machines,” and linked this claim to current deployment trends.
The x402 protocol has already processed over 169 million transactions, totaling $50,338,035.60 in volume. Coinbase reported that its Base network controls 82.1% of total agent-driven payment activity. The company also confirmed that its infrastructure supports about 250,000 daily active AI agents across its ecosystem.
Growth data shows that Base network infrastructure expanded by 400% year over year. Meanwhile, transaction behavior indicates that automated systems prefer stable digital currencies for operational consistency. Reports show that 99.8% of these transactions use the USDC stablecoin for settlement.
Tech Firms Integrate Payment Systems for AI Agents
Major technology firms have begun integrating automated billing systems that support machine-to-machine payments. Amazon Web Services enabled third-party AI agents to purchase additional cloud capacity through microtransactions. This system allows automated tools to manage computing needs without human input.
Circle, which issues USDC, reported over $100 million in transaction volume through its Agent Stack solution within four months. This platform supports programmable payments for AI systems that require continuous access to digital services. Circle confirmed that this volume came from automated transactions executed by AI agents.
Google Cloud partnered with Solana to launch the Pay.sh marketplace for decentralized service discovery. This platform allows AI agents, including Google Gemini, to locate and purchase APIs using stablecoins. The system enables transactions without user registration, which supports autonomous operations across services.
These developments indicate that companies are building infrastructure specifically for machine-based economies. Armstrong’s statements align with these ongoing deployments and recorded transaction volumes. Data from Artemis and related platforms continues to track activity growth across these systems.
