Legal Setback: Court Blocks Perplexity AI from Amazon Shopping
The aggressive expansion of AI shopping agents has hit a significant legal roadblock. A US federal judge has issued an injunction effectively barring Perplexity AI’s browser-based agents from placing orders on Amazon on behalf of users.
The Ruling
US District Judge Maxine Chesney ruled on Monday that Amazon provided “strong evidence” that Perplexity’s “Comet” browser accesses user accounts without authorization from the retail giant. The court order serves as a major blow to Perplexity’s goal of embedding its AI into the daily shopping habits of consumers.
A Long-Standing Dispute
Amazon filed the lawsuit against the AI startup last November. At the heart of the dispute is Perplexity’s “agentic” shopping feature, which allows the AI to navigate to Amazon, add products to a cart, and complete the checkout process automatically.
Amazon alleged that it had repeatedly requested Perplexity cease these automated activities, claiming the startup was “intruding” into its marketplace. Perplexity, however, has marketed this feature as a competitive advantage designed to save users time and streamline their online procurement.
What This Means for AI Agents
This ruling reinforces a growing tension between large e-commerce platforms and AI service providers. Platforms are increasingly protective of their user-interface integrity and data access protocols. As AI agents become more autonomous, we can expect “unauthorized access” to become the primary legal frontline between Silicon Valley incumbents and AI startups.
