An AI agent can shop on Amazon whether Amazon likes it or not. A US appeals court has overturned an injunction that barred Perplexity’s shopping agent from the retailer, handing an early win to the software that browses and buys on people’s behalf. Because Perplexity’s Comet agent acts only when a user tells it to, the court found it is the user, not Perplexity, who is accessing Amazon’s servers. Comet is the agent built into Perplexity’s AI browser. Alibaba has wired its own model straight into Taobao for end-to-end agentic shopping, the sort of first-party integration Amazon would prefer to a rival’s bot crawling its aisles.
