Amazon Wins Injunction Against Perplexity's AI Shopping Agent Comet
A US federal judge has ruled in favor of Amazon, banning Perplexity's shopping agent Comet from accessing its platform. The decision was made by U.S. District Court Judge Maxine Chesney in the Northern District of California on March 10, 2026.
The lawsuit between the companies dates back to November 2025, when Amazon sued Perplexity for allegedly 'trespassing' into Amazon's server using Comet. Amazon claimed that Perplexity was violating a 40-year-old federal anti-hacking law by accessing its site without permission.
Perplexity argued that its actions were legitimate and that it was simply providing users with the ability to choose which AI agent they wanted to use for shopping on Amazon. However, Chesney found in favor of Amazon, stating that the company had provided strong evidence that Perplexity accessed Amazon's site without authorization.
