Anthropic’s Three Experiments in Claude-Run Commerce: From a Fridge to a Market

Anthropic ran 3 Claude commerce experiments in 12 months, spanning a mini-fridge, a multi-agent store, and a 69-person Slack market. Project Deal closed 186 trades; Opus sellers earned $2.68 more than Haiku, while Opus buyers paid $2.45 less. The key signal: weaker-model users did not perceive the loss.

Why it matters: HKR-H/K/R all pass: Anthropic’s real-commerce agent tests include transaction counts, model deltas, and failure cases. It is a strong research analysis, not a new model launch, so it stays in the 78–84 band.
