Coinbase CEO Brian Armstrong has forecasted that the commercial scale of autonomous AI agents will eventually surpass the human economy. Armstrong emphasizes that this shift is imminent, with major companies like Amazon, Google, and Circle already deploying payment infrastructures tailored for AI agents. These agents operate without traditional financial instruments like passports or credit cards, relying instead on blockchain networks such as Coinbase's Base. To support this emerging economy, Coinbase has introduced the trading platform Agentic.market and the open payment protocol x402. This infrastructure allows AI agents to autonomously conduct transactions, such as purchasing cloud capacity via micropayments. Notably, Circle's Agent Stack solution has processed over $100 million in transactions within four months, while the x402 protocol has handled over 169 million transactions valued at over $50 million. Armstrong's vision underscores a transformative shift towards an AI-driven economic model, positioning Coinbase at its core.
