A federal judge in California granted Amazon a temporary injunction blocking Perplexity’s Comet AI shopping browser from accessing the e-commerce giant’s site, finding Amazon showed strong evidence of unauthorized access. Amazon said it spent more than $5,000 and significant employee time developing tools to thwart the AI agent, citing risks to customer data and advertising integrity from automated traffic. Perplexity called the case a bully tactic and said it will continue to fight for user choice, with the order stayed for a week to allow an appeal. The ruling underscores Amazon’s broader push to restrict third-party AI agents while it builds its own shopping assistant, Rufus.
