Agent Economy

Cloudflare launched Cloudflare Wallets, giving AI agents an identity, a stablecoin wallet, and an enforced spending cap using the x402 payment protocol - though it’s not fully live yet. This isn’t one company’s new product, it’s another piece of an industry-wide race to build the ‘AI wallet layer,’ following Coinbase’s x402, Google’s AP2, Mastercard’s Agent Pay, and Circle’s Steve. The shared conviction: spending limits belong in the infrastructure, not in AI self-restraint.

Circle publicly ran an experiment called Steve: 8 autonomous AI agents, each with its own USDC wallet, paid for data on their own via the x402 protocol and placed bets on the 2026 World Cup on Polymarket - with no human reviewing in real time. Writing from the front lines of building agentictrade, the author breaks down why the agent economy matters and why a spending cap is the key design that makes it safe for AI to spend money.
