Sam Altman's World teams up with Coinbase to prove there is a real person behind every AI transaction

World said some estimates suggest agentic commerce could reach $3 trillion to $5 trillion by 2030, with agents accounting for up to 25% of U.S. e-commerce. What to know : World, an identity project cofounded by Sam Altman, has launched AgentKit, a toolkit that lets AI agents carry cryptographic proof they are backed by a unique human via the World ID system. By integrating with Coinbase and Cloudflare’s x402 protocol for stablecoin micropayments, AgentKit aims to make AI agents verifiable economic participants rather than suspicious automated traffic. AgentKit links multiple agents to a single verified person using zero-knowledge proofs and, for now, Orb-based biometrics, enabling platforms to cap usage per human and positioning World as a foundational identity layer for an AI-driven web.
