Amazon Blocks Perplexity AI Shopping Bots with Court Order as Company Appeals Injunction

Amazon’s victory in federal court stems from a lawsuit filed in November that accused Perplexity AI of “computer fraud” for concealing when its Comet browser agent was executing purchases on a shopper’s behalf, Bloomberg reported. The judge’s preliminary injunction forces Perplexity to halt any automated buying activity on Amazon’s marketplace until the case is resolved, effectively putting a pause on what could have been a rapid expansion of AI‑driven commerce. The ruling also requires the startup to disclose the presence of the agent to users and to cease operations when Amazon requests, a demand the company allegedly ignored, according to the filing.

Perplexity’s appeal, filed through the legal services platform MLex, argues that the injunction is overly broad and threatens legitimate uses of its Comet tool, which the firm markets as a “web‑browser agent” that can streamline research and checkout tasks. The appeal seeks a stay of the order while the underlying claims are litigated, but the company has not yet provided a timeline for compliance or a detailed technical roadmap for how it will differentiate permissible functionality from the prohibited shopping automation. The lack of publicly available data on the volume of transactions processed by Comet makes it difficult to gauge the immediate economic impact on Amazon, but the injunction eliminates a potential surge of AI‑generated orders that could have strained the retailer’s fulfillment network during the holiday season.

Industry observers note that the case highlights a broader regulatory gray zone surrounding autonomous agents that interact with e‑commerce platforms. The Verge’s coverage of Perplexity describes the startup as “the answer engine with a lot of question marks,” underscoring lingering concerns about transparency and consumer consent when AI intermediaries act on users’ behalf. Wired similarly warned that shoppers “won’t be able to offload holiday shopping to AI agents anytime soon,” pointing to the legal pushback as a signal that major marketplaces are prepared to enforce strict disclosure standards. Both outlets suggest that the outcome could set a precedent for how other retailers—such as Walmart or Target—handle third‑party AI tools that automate purchases.

For Amazon, the injunction serves a dual purpose: protecting its brand integrity and safeguarding its data‑security protocols. By forcing Perplexity to stop undisclosed automated buying, Amazon can maintain tighter control over fraud detection, pricing algorithms, and inventory management. The company’s legal strategy, as outlined in the Bloomberg report, appears aimed at preventing a “race to the bottom” where AI bots undercut pricing or exploit promotional loopholes, a scenario that could erode margins and destabilize the marketplace’s equilibrium. Moreover, the court order buys Amazon time to develop its own AI‑driven shopping assistants, a move that would keep the technology in‑house and insulated from third‑party compliance risks.

The broader AI market may feel the ripple effects of the ruling, especially as developers race to embed autonomous agents into consumer-facing applications. If the court ultimately upholds the injunction, startups like Perplexity could face heightened compliance costs, including mandatory user consent dialogs and real‑time monitoring of agent activity. Conversely, a reversal or narrowing of the order could embolden other firms to pursue similar automation strategies, prompting a wave of litigation as retailers scramble to protect their platforms. As the appeal proceeds, the case will likely become a touchstone for policymakers and industry groups debating the balance between innovation and consumer protection in the era of agentic AI.
