Perplexity AI Agents Blocked from Amazon Marketplace
Judge blocks Perplexity's Comet AI agents from accessing Amazon marketplace
The case pits a fledgling open‑source chatbot against one of the world’s biggest e‑commerce platforms. Perplexity’s “Comet” AI agents were designed to browse the web, retrieve product details and even complete purchases on behalf of users. Amazon, however, says the agents slipped into its marketplace without any permission, pulling data and triggering transactions that the retailer never approved.
In court, the online retailer presented what it called “strong evidence” that the Comet browser accessed Amazon’s site “without authorization.” The judge weighed that evidence against Perplexity’s claim that its tool simply followed user prompts. What emerged was a rare legal ruling that directly addresses how autonomous agents may—or may not—interact with commercial sites. The decision has immediate implications for developers who embed shopping capabilities into AI, and it underscores the growing tension between open‑source innovation and corporate control of digital storefronts.
**Judge blocks Perplexity's AI agents from shopping on Amazon**
Judge blocks Perplexity's AI agents from shopping on Amazon Amazon provided 'strong evidence' that Perplexity's Comet AI browser accessed the marketplace 'without authorization,' according to the ruling. Amazon provided 'strong evidence' that Perplexity's Comet AI browser accessed the marketplace 'without authorization,' according to the ruling. Amazon sued Perplexity in November, alleging that it "repeatedly requested" that the AI startup stop letting its agents buy products for customers.
The company accused Perplexity of "intruding" into its marketplace and user accounts with Comet's agentic shopping feature, in violation of computer fraud and abuse laws. Amazon also alleged that Perplexity attempted to "conceal" its agentic activities by "misrepresenting the Comet browser as Google Chrome." Under the preliminary injunction, Perplexity must not access Amazon using its AI agents and must destroy any data from Amazon that it may have obtained.
Judge Maxine Chesney has ordered Perplexity’s Comet AI agents off Amazon’s marketplace. The ruling cites Amazon’s “strong evidence” that the browser accessed user accounts without permission. Consequently, the agents may no longer place orders on a shopper’s behalf.
Perplexity had marketed the feature as a seamless checkout assistant, but the injunction halts that capability pending further legal review. Whether the company can redesign the tool to comply with Amazon’s terms remains uncertain. It’s a reminder that legal constraints can outpace product hype.
The decision underscores how quickly court actions can curtail emerging AI functionalities when they intersect with existing e‑commerce platforms. No details were released about any appeal or potential settlement. Observers note that the case may prompt other retailers to scrutinize similar integrations, though the broader impact is still unclear.
For now, Perplexity must remove the shopping function from its Comet browser, and users will need to complete purchases manually. The ruling leaves open questions about how AI‑driven commerce will navigate authorization rules in the future.
