# Perplexity Comet wins Amazon court ruling, AI agents can shop for users

> The Ninth Circuit handed AI shopping agents a meaningful win on August 4, vacating Amazon's injunction against Perplexity's Comet. The court's reasoning is the interesting part: when Comet buys something on your instruction, it is you, the user, who accesses Amazon, not Perplexity accessing it without authorization. That distinction matters because Amazon had leaned on computer-fraud style arguments to keep agents off its store, and the panel rejected that framing for user-directed actions. This is far from over. Amazon's trademark and state-law claims survived, and the underlying lawsuit heads back to district court. But the appellate signal is loud. If an agent acting on a person's behalf counts as that person's own access, platforms lose one of their strongest legal levers for walling off automated shoppers. Expect this to ripple well beyond Perplexity. Every company building agents that book, buy, or browse on your behalf just got a precedent to point to, and every marketplace that wanted to block them now has to find a different argument.
