A U.S. federal court has issued a temporary injunction against Perplexity AI, preventing its AI-powered Comet browser from accessing Amazon (company)'s password-protected systems and making purchases on behalf of users. The ruling, by District Judge Maxine M. Chesney, sided with Amazon (company), which had sued Perplexity AI in November 2025, alleging computer fraud and unauthorized access. Amazon (company) claimed Perplexity AI's Comet browser accessed user accounts without Amazon (company)'s authorization, even after Amazon (company) implemented technological blocks and sent a cease-and-desist letter. Perplexity AI is appealing the decision, arguing that Amazon (company)'s lawsuit is an attempt to block its customers from using AI agents for shopping. The dispute highlights broader issues regarding AI agents' interaction with e-commerce platforms, data security, and advertising revenue models.
