Appeals Court Lifts Ban on Perplexity AI Shopping on Amazon

A Setback for Amazon in the AI Agent Wars

A U.S. appeals court has overturned a lower court's order that had temporarily blocked Perplexity AI's autonomous shopping tool from operating on Amazon's platform, according to a Reuters report cited by coverage of the ruling 1. The decision reverses a March injunction and represents a significant legal win for Perplexity as it pushes to expand its AI agents into e-commerce 1.

Why the Ruling Matters

The appellate panel found that Amazon is unlikely to succeed in proving Perplexity violated federal hacking law, a determination that marks the first appellate-level decision addressing whether AI agents can legally take actions on behalf of users across third-party websites 2. That framing elevates the case beyond a simple contract or trademark dispute between two companies, positioning it instead as an early test of how existing computer-fraud statutes apply to a new generation of autonomous software that browses, clicks, and completes purchases without direct human input at each step 2.

The Underlying Dispute

Amazon had sought to keep Perplexity's agentic shopping assistant off its site, arguing the tool accessed the platform in ways that ran afoul of federal hacking law — a claim that led to the original injunction in March 12. Perplexity, for its part, has built its business around AI systems that can search, summarize, and increasingly act on behalf of users, and an agent capable of shopping directly on Amazon would be a natural extension of that strategy. The appeals court's rejection of Amazon's likelihood of success on the hacking claim effectively clears the way, at least for now, for Perplexity's tool to resume operating on Amazon's platform 1.

Broader Stakes for AI and E-Commerce

The case sits at the intersection of two fast-moving trends: the rise of AI agents designed to act autonomously on the open web, and the reluctance of large platforms like Amazon to cede control over how, and by whom, their sites are accessed. Retailers and tech platforms have generally treated automated scraping and bot-like activity as a threat to be blocked, often citing computer-fraud and terms-of-service violations. This ruling suggests that courts may be skeptical of stretching those legal tools to cover AI agents acting transparently on a user's behalf, rather than covertly hacking or scraping data. As more companies deploy AI agents to shop, book travel, or manage accounts across third-party services, the legal boundaries tested in this dispute are likely to recur, with platforms weighing whether to fight such access in court or find commercial arrangements instead. Both accounts agree on the core outcome — Perplexity prevailing at the appellate stage — even as the coverage frames the significance somewhat differently, from a straightforward legal reversal to a landmark precedent for AI agents' rights to act online 12.
