Amazon Wins Legal Victory Against Perplexity, Blocks Unauthorized AI Shopping Agent

In a landmark ruling that underscores the escalating tension between AI-powered tools and e-commerce giants, a federal judge has granted Amazon a temporary injunction against Perplexity, an AI search startup, effectively halting its AI browser agent, Comet, from scraping Amazon’s website and making unauthorized purchases on behalf of users. The decision, issued by U.S. District Judge Maxine Chesney, marks a significant win for Amazon in its ongoing battle to protect its digital infrastructure and customer data from automated intrusions.

The legal dispute traces back to November 2025, when Amazon filed a lawsuit against Perplexity, accusing the AI startup of computer fraud and demanding that it cease allowing Comet to operate on its platform. Amazon argued that Comet, designed to act as an autonomous shopping assistant, was accessing its systems without permission, posing severe security risks to customer accounts and disrupting its advertising ecosystem.

Judge Chesney’s ruling, dated March 10, 2026, sided with Amazon, citing “strong evidence” that Perplexity’s Comet browser accessed Amazon’s website at the user’s direction but “without authorization” from the e-commerce giant. The judge emphasized that Amazon had provided “essentially undisputed evidence” of the financial and operational toll imposed by Comet’s activities. According to court filings, Amazon spent over $5,000 responding to the issue, including “numerous hours” where employees worked to develop tools to block Comet from accessing private customer tools and to prevent future unauthorized access.

“This is not just a technical inconvenience; it’s a breach of trust and a threat to our customers’ security,” Amazon stated in its original complaint. The company highlighted that Comet’s ability to act within protected computer systems, including private customer accounts requiring passwords, posed significant risks to sensitive data. Furthermore, Amazon argued that the AI agent’s activities created challenges for its advertising business, as automated traffic generated by Comet had to be detected and filtered out before advertisers could be billed. “This requires modifications to Amazon’s advertising systems, including developing new detection mechanisms to identify and exclude automated traffic,” the company wrote. “These system adaptations are necessary to maintain contractual obligations with advertisers who pay only for legitimate human impressions.”

The ruling includes a weeklong stay to allow Perplexity to appeal the order, providing a brief window for the AI startup to challenge the injunction. However, the decision has already sent shockwaves through the tech industry, raising questions about the boundaries of AI-driven automation and the responsibilities of companies deploying such technologies.

Perplexity, known for its AI-powered search engine, has yet to issue a detailed response to the ruling. The company’s Comet browser was designed to streamline online shopping by autonomously navigating e-commerce platforms, comparing prices, and completing purchases on behalf of users. While the tool promised convenience, Amazon’s lawsuit underscores the potential risks and ethical dilemmas associated with AI agents operating without explicit consent from the platforms they interact with.

This case is part of a broader debate about the role of AI in commerce and the need for clear regulations to govern its use. As AI technologies become increasingly sophisticated, companies like Amazon are grappling with how to balance innovation with the protection of their digital ecosystems. The outcome of this legal battle could set a precedent for how similar disputes are handled in the future, particularly as more businesses adopt AI-driven tools to enhance customer experiences.

For now, Amazon’s victory serves as a stark reminder of the challenges posed by unregulated AI agents and the importance of securing digital platforms against unauthorized access. As the tech industry continues to evolve, the line between innovation and intrusion remains a contentious issue, with this ruling marking a pivotal moment in the ongoing struggle to define the boundaries of AI in the digital age.
