Anthropic ran a pilot marketplace where its AI agents acted as buyers and sellers, enabling employees to trade real goods for real money. The four‑day experiment involved 69 staff members, each given a $100 gift‑card budget. Participants completed 186 transactions worth more than $4,000. The company found that agents powered by its most advanced model secured better outcomes, though users did not perceive the advantage. Anthropic says the test highlights both the promise of agent‑on‑agent commerce and the risk of hidden “agent quality” gaps.Read more
