Anthropic just proved agent commerce works. Their own data shows why verification infrastructure needs to exist.

This is our third post in a series on agentic commerce. Previously: AI shopping agents have no standard way to verify ants - so we built one and AI Agents Need a Trust Layer Before They Can Transact. They called it Project Deal. For one week in December 2025, they created a Craigslist-style internal marketplace - but with a twist: every transaction was handled entirely by Claude agents acting on behalf of 69 employees. No human intervention once the experiment started. Agents posted listings, made offers, countered, and closed deals autonomously via Slack.
