Perplexity Amazon Shopping: What It Means for Sellers

If you typed "perplexity amazon shopping" into Google, you're probably expecting some kind of official partnership, the way OpenAI has partnered with Walmart for ChatGPT checkout. That's not what's going on here. What you're actually looking for is a legal fight, and it's a much bigger deal for Amazon sellers than a partnership would have been.

Since late 2025, Perplexity and Amazon have been in an open dispute over whether Perplexity's AI browser, Comet, is allowed to shop on Amazon.com on a user's behalf. Amazon tried to block it in court. In August 2026, a federal appeals court sided with Perplexity, and the ruling now shapes how every AI shopping agent, not just Comet, is allowed to interact with retail sites they don't have a deal with.

For a seller with listings on Amazon, this isn't abstract. It's about whether an AI agent that has never seen your sponsored placement, your Amazon Choice badge, or your review count can still put a competitor's product in someone's cart instead of yours.

What "Perplexity Amazon Shopping" Actually Means

There's no Perplexity-Amazon shopping integration. There's no feed agreement, no checkout partnership, nothing resembling what Perplexity has built with Shopify merchants through its own Buy with Pro checkout. What exists instead is Comet, Perplexity's agentic browser, which can log into a user's own Amazon account, search, compare, and complete a purchase, the same way the person would if they were doing it themselves in a normal tab.

Amazon doesn't want that traffic. In an October 31, 2025 cease-and-desist letter, Amazon accused Perplexity of disguising Comet as a normal Google Chrome browser and refusing to identify it as an AI agent while it shopped inside the Amazon Store, in violation of Amazon's terms of service and an earlier 2024 agreement to pause agentic shopping. Perplexity didn't comply, and the dispute went to court.

The Timeline, in Order

• October 31, 2025: Amazon sends Perplexity a cease-and-desist letter, alleging Comet accesses Amazon's site without identifying itself as an AI agent.
• Early 2026: Amazon escalates to a lawsuit, arguing Comet's access violates the federal Computer Fraud and Abuse Act (CFAA) and California's equivalent state statute, and asks for an injunction.
• March 10, 2026: U.S. District Judge Maxine Chesney grants Amazon's request, finding Amazon had shown "strong evidence" that Comet accessed Amazon's servers without authorization, and temporarily blocks the agent from shopping on Amazon.
• August 4, 2026: The Ninth Circuit Court of Appeals vacates the injunction and sends the case back to the lower court, ruling Amazon is unlikely to win its CFAA claim.

You can read the actual opinion, not a summary of it, in the Ninth Circuit's published ruling (case 26-1444). It's short for a federal appeals ruling and worth skimming if you want the reasoning firsthand instead of secondhand.

Why the Ninth Circuit Sided With Perplexity

The court's reasoning comes down to who is technically doing the "accessing." Comet doesn't have its own server-to-server connection into Amazon's backend. Instead, it works the way a human with a browser extension would: it takes screenshots of what's on the user's screen, sends them to Perplexity's servers for interpretation, and sends navigation instructions back down to the user's own device, which then clicks and types inside the user's already-logged-in Amazon session.

As law firm Cooley summarized it, the panel treated this the same way it would treat Safari or Chrome: "it was the user who 'accessed' Amazon's computers, with the help of Perplexity's AI agent," not Perplexity itself. The court called the assistant "a tool, not a person for statutory purposes." An earlier report from PYMNTS notes this is the first time a federal appeals court has directly ruled on whether an AI agent acting on a user's instructions can be treated as legally distinct from the user.

This isn't a final win for Perplexity. The case goes back to the district court for further proceedings, and Amazon has said it's evaluating its next move, which could include amending its claims around trademark, deceptive trade practices, or breach of the 2024 agreement instead of relying on the CFAA. But for now, the door that Amazon tried to shut in March is open again.

Why Amazon Is Fighting This So Hard

It's not really about server load. It's about who controls product discovery on Amazon, and by extension, who gets paid for it.

• Sponsored placements are the core of Amazon's ad business, and an agent that scans a page for the best-matching product doesn't necessarily click the sponsored slot at the top. Comet compares options based on its own read of price, reviews, and stated preferences, not on who paid for placement.
• Amazon's own ranking signals get bypassed, since Comet isn't using Amazon's search bar or filters the way a shopper normally would. It's reading the rendered page and deciding for itself which listing best answers the user's question.
• Upsells and cross-sells lose their usual triggers, because an agent completing a specific, narrow task ("buy the cheapest 2-pack of the AA batteries I usually order") skips the browsing behavior that normally surfaces bundles, related items, and subscribe-and-save prompts.

Amazon's Actual Answer: Alexa for Shopping, Not a Perplexity Deal

While it was fighting Perplexity in court, Amazon was also building its own answer to the same problem: an in-house AI shopping agent it fully controls. On May 13, 2026, Amazon retired its earlier Rufus chatbot and replaced it with Alexa for Shopping, an agent built directly into the main Amazon search bar rather than a separate side panel.

According to Amazon's own announcement, Alexa for Shopping can answer questions typed straight into search, build personalized shopping guides for bigger purchases, generate product comparisons, show up to a year of price history, and automate routine reordering based on a shopper's history. Rufus itself had reportedly reached over 300 million customers and was tied to roughly $12 billion in annualized incremental sales before the switch, according to Amazon's own reporting, so the successor agent inherits a genuinely large audience.

The strategic point for sellers: Amazon has zero interest in letting a third-party agent like Comet become the default way people shop its marketplace, because that hands product-discovery power to a company Amazon doesn't control and can't monetize through ads. Building its own agent is Amazon's way of keeping that layer in-house.

What This Actually Changes for Amazon Third-Party Sellers

Whatever happens next in court, the underlying behavior isn't going away. More shoppers are going to start a purchase decision in a chat window before they ever open Amazon's app, and some of them will hand the actual buying step to an agent. That splits your visibility problem into two separate battles.

• Battle one is inside Amazon: Alexa for Shopping and its Rufus-era predecessor draw on your listing content, not your ad spend, to decide what to recommend inside a conversational answer. Thin bullet points, missing size or material details, and a low review count make you invisible to the agent even if your sponsored ad is winning the top slot above the fold.
• Battle two is outside Amazon: if a shopper asks Comet, ChatGPT, or Gemini to find and buy something, and that agent lands on your Amazon listing (or a competitor's) as its evidence, the deciding factors are price clarity, specific product attributes in your title and description, and review sentiment the agent can quote, not anything you've bid on.
• Both battles reward the same fix: complete, specific, plain-language product data. Vague marketing copy ("premium quality, built to last") gives an AI agent nothing concrete to cite. A sentence like "304 stainless steel, holds 32oz, dishwasher safe" gives it exactly what it needs to justify a recommendation.

Practical Steps for Sellers Right Now

• Audit your bullet points for extractable facts: materials, dimensions, compatibility, and use cases stated as plain sentences, not adjective-heavy marketing lines.
• Keep your review volume and recency healthy: both Alexa for Shopping and third-party agents lean on review sentiment as a trust signal when there's no ad spend to weight the decision.
• Don't assume sponsored placement protects you: budget for it as you do today, but treat organic listing quality as the layer that determines whether an agent even considers you at all.
• Watch your non-Amazon storefront too: if you sell on Shopify or your own site as well as Amazon, Perplexity's merchant feed program indexes those listings separately from anything happening in the Amazon dispute, and it's a channel you can actually control end to end.
• Track how you actually show up, rather than guessing. Running your brand and top products through queries on ChatGPT, Perplexity, and Gemini on a regular basis tells you whether you're being recommended at all before a customer ever reaches a marketplace.

Perplexity Comet vs. Amazon's Alexa for Shopping

How Perplexity's Own Shopping Feature Actually Works (Separate From the Lawsuit)

Worth separating out: Perplexity has run its own above-board shopping feature since November 2024, well before the Amazon dispute became public. That feature, Buy with Pro, lets Perplexity Pro subscribers complete checkout without leaving the chat, through direct merchant integrations rather than by browsing a retailer's site as a logged-in user. This is the legitimate, consenting side of Perplexity commerce, and it has nothing to do with Comet's disputed access to Amazon.

Merchants on Shopify, Walmart, and BigCommerce get indexed into this system through direct partnerships. Everyone else can submit a product feed through Perplexity's merchant program, which charges no listing fee and takes no cut of the sale. Amazon is deliberately absent from that partner list, which is exactly why Comet has to fall back on browsing a user's own logged-in Amazon session instead of pulling from a clean feed, and exactly why the legal fight exists in the first place.

Does This Ruling Apply Beyond Perplexity?

Yes, and that's the part worth paying attention to even if you don't have strong feelings about Perplexity specifically. The Ninth Circuit's browser analogy, that an agent relaying a user's own instructions isn't legally the same as the company accessing the site itself, isn't written to apply only to Comet. Any agentic browser built the same way (screenshot in, instructions out, executed inside the user's own authenticated session) can point to this ruling.

That includes agent features inside ChatGPT and Gemini as both companies keep expanding what their own browsing agents can do unsupervised. Retailers that don't want any AI agent completing purchases on their site can't lean on the CFAA to stop it. Amazon's own next move, per its statement after the ruling, is likely to shift toward contract and trademark claims instead, which is a slower and narrower path than an anti-hacking statute would have been.

Frequently Asked Questions

Is there an official Perplexity and Amazon shopping partnership?

No. Amazon has not partnered with Perplexity the way it's discussed partnering on AI shopping with Google, and the way OpenAI has with Walmart. The only relationship between the two companies right now is adversarial, playing out in federal court.

Can Perplexity's Comet still buy things on Amazon today?

As of the Ninth Circuit's August 4, 2026 ruling, yes, the injunction that blocked it was vacated. The underlying case is still active in the district court, so this could change again depending on how Amazon proceeds with its remaining claims.

Should I block AI shopping agents from my own Amazon listings?

You can't, in any practical sense. Comet and similar agents act inside a shopper's own logged-in session, reading whatever page the shopper's account can already see. Your only real lever is the quality and completeness of the listing content itself, which decides whether the agent recommends you or a competitor.

Where This Goes From Here

The Ninth Circuit's ruling is being read as a template for how courts will treat other agentic browsers, not just Comet, when they act on other retailers' sites without a formal deal in place. That means the tension between Amazon and third-party AI agents almost certainly isn't over. Expect Amazon to pursue narrower legal theories (contract and trademark claims rather than CFAA) while also leaning harder on Alexa for Shopping as the agent it wants shoppers using by default.

For sellers, the practical takeaway holds regardless of who wins the next round: the products that get recommended by an AI agent, on Amazon or off it, are the ones with data an AI agent can actually use. That's a listing-quality problem you can fix today, not a legal outcome you have to wait on.
