A federal judge issued a preliminary injunction blocking Perplexity’s Comet AI browser agents from placing Amazon orders on a user’s behalf, ruling that Amazon provided strong evidence the agents accessed user accounts without authorization.

Perplexity has one week to appeal the ruling; if it does not appeal, it must stop accessing password-protected areas of Amazon and destroy its copies of Amazon data.

Perplexity has not publicly commented; Amazon said the decision protects a trusted shopping experience for customers.

The case underscores tensions between retailers and AI developers over automated shopping and access to third-party marketplaces.

Perplexity argues for user autonomy in choosing AI tools and said it will continue to fight for internet users’ right to use any AI they want.

Perplexity publicly disputed the allegations and vowed to continue fighting for user choice in AI tools.

Perplexity stated it will advocate for user choice regarding AI tools and shopping bots.

No financial terms of any settlement or damages are disclosed in the summary; the focus remains on the ruling and appeal.

The injunction highlights broader implications for how commercial AI agents can operate on behalf of users, balancing consumer choice, innovation, and online security.

The injunction includes a one-week stay to allow Perplexity to appeal, and the case will proceed in court.

Perplexity has already appealed the injunction, signaling ongoing legal dispute between Amazon and Perplexity over automated purchasing.

The ruling was reported by Bloomberg and comes from U.S. District Judge Maxine Chesney; Perplexity will have the opportunity to appeal.
