Amazon has blocked Meta’s Muse AI assistant from accessing its e-commerce platform to browse and purchase products on behalf of users, escalating a growing dispute over who controls the future of AI-powered shopping. Amazon says Meta did not obtain permission before allowing Muse to interact with its website and raised concerns about customer privacy, account security and the handling of sensitive information.

The dispute highlights a bigger conflict between traditional online retailers and companies developing autonomous AI agents. While Meta wants Muse to act as a personal assistant that can shop across different websites, Amazon wants third-party services to operate transparently and respect individual retailers’ decisions about automated access. The disagreement could influence how AI shopping agents interact with major e-commerce platforms in the coming years.

Why Amazon Blocked Meta’s Muse AI Assistant

Amazon began blocking Meta’s Muse agent from its shopping website in September 2026. Users attempting to shop on Amazon through Muse encountered a warning stating that continued access by an unauthorised AI agent violated Amazon’s Conditions of Use.

Amazon said Meta had not informed the company that Muse would access its retail platform. It also argued that the AI assistant did not properly identify itself while browsing and appeared to capture and store customer credentials.

According to Amazon, an automated third-party application that makes purchases on behalf of customers should operate openly and respect the service provider’s decision about whether to participate.

The company also raised concerns about Muse potentially accessing customer account pages, order histories and other sensitive information. Amazon believes that an external agent operating without its authorisation creates additional security and accountability risks.

These are Amazon’s stated concerns and should not be interpreted as independently established evidence that Muse misused customer information.

What Is Meta’s Muse AI and How Does It Work?

<escape> </escape>Meta introduced Muse in September 2026 as a personal AI agent designed to complete multi-step tasks rather than simply respond to individual questions.

Unlike a conventional chatbot, Muse can interact with different online services and carry out activities such as shopping, organising schedules, managing tasks and booking appointments.

Its shopping capabilities allow users to ask the agent to find products, compare options and complete purchases. Instead of manually navigating multiple websites, users can delegate parts of the shopping process to the AI assistant.

Meta says Muse operates through a secure virtual machine with its own browser. It also uses a separate monitoring system called Sentinel to review actions before the agent sends information to the internet.

The company has said Muse cannot directly see users’ passwords or payment methods. It has also explained that credentials provided by users are stored securely so the agent can use them without accessing the underlying information.

However, Amazon argues that these protections do not resolve its concerns about an unauthorised AI agent interacting with customer accounts on its platform.

The Dispute Is About More Than Customer Security

Although Amazon has publicly emphasised security and transparency, the dispute also raises important commercial questions about the future of online shopping.

Amazon’s traditional e-commerce model depends heavily on customers visiting its website, searching for products, comparing listings and making purchasing decisions.

Its advertising business benefits from this activity. Brands pay to promote products through sponsored placements, search results and other advertising formats across Amazon’s marketplace.

AI shopping agents could change this behaviour.

Instead of browsing Amazon directly, a customer could ask Muse to find the cheapest product, compare specifications across retailers and complete a purchase automatically. The customer might never see Amazon’s sponsored listings or interact with its recommendation system.

This could reduce the influence of Amazon’s advertising placements if AI agents increasingly become the starting point for online purchases.

Amazon generated approximately $68 billion in advertising revenue in 2025, making advertising an important part of its business beyond retail sales.

The company therefore has a commercial interest in retaining control over how customers discover products and interact with its marketplace.

Meta’s Muse Has Gained Attention From Users

Muse’s launch has attracted considerable attention in the United States and Canada. According to a Wall Street Journal report published on November 1, more than 10 million people in the two countries had set up Muse agents during its first six weeks.

The report also highlighted how the service could change the relationship between shoppers, retailers and online advertising platforms.

Muse is not limited to Amazon. Other retailers and technology companies are taking different approaches to the development of AI-powered shopping.

Walmart and Shopify have pursued partnerships with Meta around AI-driven product discovery and shopping experiences. Their approach suggests that some retailers see external AI agents as an additional channel for reaching customers rather than simply a threat to their existing platforms.

This creates a divided market in which retailers must decide whether to cooperate with independent AI assistants, build their own agents or restrict automated access.

Amazon Is Developing Its Own AI Shopping Tools

Amazon is not opposed to AI-powered shopping itself. The company has been developing its own tools to help customers discover products and make purchasing decisions.

One of its initiatives is Alexa for Shopping, which can research products, compare options, track deals and provide personalised recommendations.

Amazon CEO Andy Jassy discussed the growing competition from external AI shopping agents during the company’s October 29 earnings call.

He said external agentic shopping was not meaningfully affecting Amazon’s advertising business at present. Jassy also argued that relatively few customers were shopping through external AI agents and that the experience was not yet more convenient than visiting a retailer directly.

Amazon has also introduced Buy for Me, a feature that helps customers discover and purchase products from external retailers through Amazon’s shopping experience.

The company says its own shopping tools operate with greater transparency and provide businesses with ways to manage their participation.

This illustrates the central difference in the dispute: Amazon wants to develop AI shopping experiences while maintaining control over how third-party services access its marketplace.

Amazon’s Move Reflects a Wider Industry Conflict

Amazon’s decision is part of a broader effort by online retailers to control automated access to their platforms.

The company has previously taken action against other AI-powered shopping services, including Perplexity’s Comet browser. The disagreement raised questions about whether an AI agent can access a retailer’s website on behalf of a user without the retailer’s permission.

The legal debate has also evolved. In August 2026, a US appeals court overturned a preliminary injunction that had restricted Perplexity’s shopping agent from accessing Amazon. The ruling did not settle every possible contractual or terms-of-service dispute between the companies.

The Meta dispute therefore reflects a larger question that the technology industry has yet to resolve: should a user be able to authorise an independent AI agent to shop across the internet, or should each retailer have the power to decide which agents can interact with its platform?

There is no universally accepted approach yet.

The Bigger Picture

AI shopping agents could change how people discover products, compare prices and complete purchases. If these tools become widely adopted, retailers may have to compete not only for customers’ attention but also for visibility within AI-generated recommendations.

For consumers, independent agents could make shopping more convenient by comparing products across multiple websites. For retailers, however, the same technology could reduce direct customer engagement, weaken advertising influence and create new questions about responsibility when automated purchases go wrong.

Amazon’s decision to block Muse demonstrates that the transition to agentic commerce will involve negotiations over access, privacy, security, commercial control and consumer choice. The outcome could shape the next generation of online retail.

Looking Ahead

The immediate question is whether Meta and Amazon can reach an agreement that allows Muse to access Amazon’s marketplace under clearly defined conditions. Such an arrangement would likely require greater transparency around automated browsing, customer authorisation, credential handling and purchase approvals. Neither company’s public position guarantees that an agreement will be reached.

Over the longer term, competition between independent AI agents and retailer-owned shopping assistants is likely to intensify. Meta wants Muse to help users complete tasks across different services, while Amazon wants customers to continue using its own shopping ecosystem. The companies’ disagreement could become an important test case for how AI agents and traditional online platforms coexist.
