Amazon (NASDAQ:AMZN) has blocked Meta Platforms’ (NASDAQ:META) Muse AI agent from shopping on its retail site, escalating a broader fight over who controls the customer relationship as autonomous AI agents begin handling more online purchases. For investors, the dispute matters because third-party agents could eventually disrupt Amazon’s lucrative advertising business by steering consumers directly to products while bypassing parts of its native storefront.
Muse is designed to perform online tasks for users, including finding products, scheduling activities and automating purchases.
Amazon said Muse has been blocked since Sunday and is part of a wider restriction on third-party shopping agents. OpenAI’s ChatGPT, Alphabet’s Gemini and Perplexity’s Comet are also prohibited from shopping directly on Amazon.
The company argues that outside agents may access sensitive customer information, fail to properly identify themselves and operate without Amazon’s consent.
We think it’s fairly straightforward that third-party applications that offer to make purchases on behalf of customers from other businesses should operate openly and respect service provider decisions about whether or not to participate. This helps ensure a safe, secure, and reliable customer experience, and it is how others operate, including food delivery apps and the restaurants they take orders for, delivery services apps and the stores they shop from, and online travel agencies and the airlines they book tickets with for customers, Amazon spokesperson Lara Hendrickson said. Agentic third-party applications such as Muse have the same obligations, and we’ve requested that Meta remove Amazon from the experience.
The economic stakes go beyond security.
If AI agents increasingly decide what consumers buy, they could weaken Amazon’s ability to monetize sponsored listings and control product discovery inside its marketplace.
Investor Takeaway
Investors should watch whether Amazon maintains its closed approach or eventually negotiates access terms with major AI platforms. The key issue is advertising economics. If shoppers increasingly rely on autonomous agents rather than browsing Amazon directly, sponsored-product visibility could become less valuable. For Meta, the restriction limits Muse’s usefulness in one of the world’s largest online marketplaces. The next phase of the agentic-commerce battle will likely revolve around access, attribution and who ultimately owns the purchasing interface.
