Federal judge blocks Perplexity’s AI browser from making Amazon purchases

A federal judge granted a temporary injunction preventing Perplexity’s Comet AI browser from accessing, attempting to access, or facilitating access to Amazon user accounts and ordered deletion of Amazon account/customer data, finding Amazon likely to succeed on claims that the agents accessed password-protected accounts without Amazon’s authorization. Amazon argued the agents made unauthorized purchases, degraded the shopping experience, required engineering effort to block, and posed cybersecurity risks (including potential hijacking of AI browsers), while Perplexity contended users had authorized purchases and that blocking agents would harm innovation.
