Coinbase AI agent trading expands into US stocks, ETFs and micropayments

Coinbase is betting that artificial intelligence agents are about to become real market participants, not just chatbots that answer questions. Starting this week, Coinbase AI agent trading now extends beyond crypto and derivatives into regulated US stocks and ETFs, letting autonomous software handle research, payments and trade execution inside a single account. The update, rolled out through Coinbase for Agents, pairs equities access with a new micropayments system called x402, which lets an agent pay small fees for data or model outputs the instant it needs them.

Key takeaways

• Coinbase for Agents now supports trading US stocks and ETFs alongside the crypto and derivatives already available on the platform.
• Securities trade through Coinbase Capital Markets Corp., a member of FINRA and SIPC, with Apex Fintech Solutions handling clearing and custody.
• The platform offers thousands of US stocks and ETFs with 24/5 trading, fractional shares starting at $1, and zero commissions.
• The x402 payments protocol has processed more than 230 million transactions and over $54 million in volume, with Coinbase acting as the top facilitator.
• Users retain control through configurable spending limits, asset permissions and per-action approval guardrails.
