Amazon Accuses Perplexity of Computer Fraud, Demands It Stop AI Agent From Buying On Its Site (bloomberg.com)

(Tuesday November 04, 2025 @05:30PM (msmash) from the one-click-too-far dept.)


Amazon has [1]sent a cease-and-desist letter to Perplexity AI demanding that the AI search startup stop allowing its AI browser agent, Comet, to make purchases online for users. From a report:

> The e-commerce giant is accusing Perplexity of committing computer fraud by failing to disclose when its AI agent is shopping on a user's behalf, in violation of Amazon's terms of service, according to people familiar with the letter sent on Friday. The document also said Perplexity's tool degraded the Amazon shopping experience and introduced privacy vulnerabilities, said the people, who spoke on condition of anonymity to discuss internal matters.

>

> In response, Perplexity said Amazon is bullying a smaller competitor with a rival AI agent shopping product. The clash between Amazon and Perplexity offers an early glimpse into a looming debate over how to handle the proliferation of so-called AI agents that field more complex tasks online for users, including shopping. Like OpenAI and Alphabet's Google, Perplexity has pushed to rethink the traditional web browser around AI, with the goal of having it streamline more actions for users, such as drafting emails and conducting research.

Exactly. And that by using an AI agent it means they can't monetize with advertisements because the AI is never going to click such. Likely not ideal for their analytics either.

The third-party AI might also do a better job (from the customer's perspective) depending on the data it has vs. Alexa, because the third-party AI can make buying decisions based solely on the information it has on the user. As someone else mentioned, the third-party AI wont favor brands/items/sellers Amazon is promoting.

I expect that is what this is really about. Amazon wants to watch you shop and Amazon wants to influence how you shop by the order it presents results to you, what related items it shows you, various pricing signals, etc.

All that breaks down if some AI agent is sifting the results Amazon returns. The lose the opportunity to gauge your real interest by how long you linger on a product page, they lose the opportunity to cross sell you, they can't try out A/B strategies on you if AI is doing your shopping.

Worse than that, if the buyer is only interacting with the AI, the AI could easily shop elsewhere. The customer, rather than thinking "I need to buy this, let's see what they have on amazon", could come to think "I need to buy this, let's ask the AI to get for me", which might be amazon today, but could easily change, for good reasons or even maybe because of a deal between the AI and some shopping site.

I think there's a bigger issue at play. A sale is a legal contract involving two parties each exchanging something with each other. If one of those parties is non-human that immediately creates a question as to whether it can form a valid contract in the first place.

I'm sure someone has just had the bright idea to chime in about corporations not being people but being able to enter into contracts without considering why it would be horrible if they weren't able to, while also simultaneously failing to co

If I tell you to buy 'Y' from Amazon using my account, I have given authorization for that purchase even though it is not me, the owner of the account, making the purchase.

In a similar fashion, Perplexity can claim the user telling their software to make the purchase is no different. That it is not a human is irrelevant. The owner of the account has given permission to make the purchases.

Some possibilities:

-The agent buys the wrong thing and Amazon sees a substantially higher rate of returns or other bad customer feedback

-The agent buys one thing despite Amazon search results trying to push a different option

-Amazon's upsell for "you may also like" is tanked by the agentic purchaasing.

I've watched several items in my saved items list creep steadily up in the last two months. Most everyone here knows what comes next. When the after thanksgiving stupidity hits the items will go 'on sale' at a slightly higher price than they were a few months before. Having a AI agent mixed in that isn't in on the scam would interfere with their scam.

First, I think Comet is a stupid, brain-smoothing security risk.

Second, trying to tell me the customer I can't use Perplexity to shop is like saying I can't use Safari or Chrome or whatever. Sure you could put technical roadblocks in place to prevent it, but it's stupid for Amazon to try and enforce this.

I think Amazon sees that a good shopping agent doesn't need to go to 3 or 4 big sites looking for good prices - they can go to hundreds or thousands of sites and find the best deal - no need for 3rd party resellers to give a cut to Amazon in that situation, just have a site listing your items and terms in a way that makes it easy for an "AI" agent to browse and forget selling through Amazon.

I think it is a bad idea to let an AI shop in a (semi-)automated way, but if Amazon can disallow users to use certain programs to access their site, they (and other sites) can also start making rules about adblockers, supported browsers in general and other details about what software may be used with their site.
