US appeals court allows Perplexity's AI shopping agent back on Amazon

The 9th US Circuit Court of Appeals has lifted an injunction against Perplexity, allowing its AI shopping agents to operate on Amazon. The court determined that users access Amazon through the agents, not Perplexity itself, making it unlikely that the startup violated federal computer fraud laws. This ruling marks the first federal appellate decision regarding the legality of AI agents accessing online platforms on behalf of users. Amazon had previously sued Perplexity in November 2025, alleging that the startup's agents accessed customer accounts without authorization, but the court sided with Perplexity's argument that the agents act on behalf of users.

• Perplexity's AI agents can log into user accounts and place orders, raising questions about AI's legal status in online transactions.
