In a preliminary ruling, a US judge orders Perplexity to stop using its Comet browser for purchases on behalf of users, and to destroy copies of Amazon's data
Perplexity AI Inc. must for now stop using its Comet web browser agent to make purchases on behalf of shoppers …
Context & Ripple Effects
Amazon's dispute with Perplexity began with a lawsuit and cease-and-desist over Comet-assisted purchases, turning a browser-agent feature into a test of who controls automated access to a marketplace.
The conflict follows Perplexity's push to broaden Comet beyond its initial premium rollout; its launch of an AI browser to compete with Chrome positioned the product as an interface for carrying out tasks, not just finding information.
First-order effects
- Perplexity must pause Comet's purchase-making use on Amazon while the preliminary order stands and destroy the Amazon data covered by the ruling.
- Amazon immediately preserves control over how transactions are initiated on its marketplace, while Comet users lose that automated purchasing path for now.
Second-order effects
- Perplexity must separate or redesign the shopping capability from the browser experience if it wants to keep serving users without the enjoined Amazon workflow.
- Other agentic-shopping products face a clearer incentive to seek platform permission or constrain automated actions, rather than assume that a user's instruction alone settles access rights.
Third-order effects
- If similar disputes produce comparable rulings, agentic commerce may develop around negotiated platform access and technical controls, giving major marketplaces greater influence over which agents can transact.
- The case also sharpens a durable product boundary: AI browsers can automate user tasks, but the availability of those tasks may depend on the underlying service's terms and data-access rules.
The trend: This is one data point in the shift from open-ended web automation toward permissioned agentic commerce, where platforms contest how AI agents access data and complete transactions.
