US Court Issues Temporary Injunction Against Perplexity AI's Amazon Shopping Tool
A federal court in San Francisco has ordered artificial intelligence startup Perplexity AI to immediately cease using its Comet AI browser agent for making purchases on Amazon's online marketplace. This preliminary injunction represents a significant development in the ongoing legal confrontation between the technology giant and the AI firm, centering on the use of automated tools that shop on behalf of customers without explicit platform authorization.
Background of the Legal Dispute and Court's Rationale
According to detailed reporting from Bloomberg, Amazon initiated this legal action in November 2025 by filing a lawsuit that accuses Perplexity of computer fraud. The e-commerce behemoth alleges that the Comet browser agent failed to properly disclose when it was shopping for genuine users and continued to utilize Amazon's platform even after receiving explicit requests to stop such activities.
District Judge Maxine Chesney, who is presiding over this consequential case, articulated in her court order that "Amazon has provided strong evidence that Perplexity, through its Comet browser, accesses with the Amazon user's permission but without authorization by Amazon, the user's password-protected account." This statement underscores the court's concern about the boundaries of user consent versus platform authorization in the rapidly evolving landscape of AI-powered shopping assistants.
Immediate Consequences and Broader Implications
The court's directive specifically mandates that Perplexity must immediately stop accessing password-protected sections of Amazon's systems, which notably includes Prime subscriber accounts. Furthermore, the AI company is required to delete any copies of Amazon's data obtained through these means. Recognizing the potential disruption, the court has wisely paused the enforcement of this ruling for one week to allow Perplexity adequate time to file an appeal.
Amazon spokesperson Lara Hendrickson emphasized the importance of this development in an emailed statement to Bloomberg, declaring, "The preliminary injunction will prevent Perplexity's unauthorized access to the Amazon store and is an important step in maintaining a trusted shopping experience for Amazon customers. We look forward to continuing to make our case in court."
Wider Context: AI Agents Reshaping Digital Commerce
This legal confrontation vividly illustrates how courts are increasingly being called upon to establish clear boundaries for AI agents that perform sophisticated online tasks, including automated shopping, on behalf of users. The proliferation of such advanced tools could potentially disrupt the massive $350 billion United States digital advertising market, where retailers and brands heavily invest in visibility across search results on platforms like Google and Amazon, as well as on various social media networks.
Amazon reported substantial advertising revenue of $68.6 billion in 2025, highlighting the significant financial stakes involved in how shopping and advertising interactions are conducted on its platform. Interestingly, Amazon's founder Jeff Bezos is an investor in Perplexity AI, which was recently valued at an impressive $20 billion. The AI startup has ambitious plans to revolutionize web search and other online activities through its AI-based tools, potentially altering the competitive dynamics of the digital advertising landscape.
This case represents a critical test for how existing legal frameworks will adapt to regulate the emerging capabilities of artificial intelligence in commercial environments, setting potential precedents for future disputes between technology platforms and third-party AI developers.
