Amazon wins preliminary injunction against Perplexity's AI shopping agent. A federal judge ruled that Perplexity's Comet browser tool unlawfully accessed password-protected Amazon accounts and made purchases without Amazon's authorization, even though users had granted permission. The distinction matters significantly: user consent differs from company authorization. Amazon demonstrated strong evidence of unauthorized access, and the injunction bars Perplexity from reaching Prime accounts while requiring destruction of previously collected Amazon data. This case represents one of the first major courtroom tests of agentic commerce. The ruling signals retailers may successfully prevent outside AI agents from intercepting customer relationships and bypassing high-margin features like ads and sponsored listings.
