Court Reinstates Perplexity's AI Agent on Amazon

The Ninth Circuit Court of Appeals overturned a March injunction and allowed Perplexity's AI agent to resume operating on Amazon. The agent is built into the Comet browser: it logs into the user's account and places orders autonomously, without any action required from the user. Amazon filed suit in November, claiming the agent violates the Computer Fraud and Abuse Act.

The court sided with Perplexity: "It is the users who access Amazon's platform through agents, not Perplexity itself." The case isn't closed — Amazon is evaluating next steps — but the injunction has been lifted.

This is the first U.S. federal appeals court ruling on whether AI agents can legally act on third-party platforms on behalf of users. The precedent opens legal space for the entire autonomous-agent industry — the agents that book, buy, and pay on people's behalf.
