$AMZN Blocks $META's Muse AI From Shopping Platform as Battle for Agentic Commerce Begins

Amazon ($AMZN) has blocked Meta Platforms' ($META) Muse AI agent from accessing its marketplace, citing terms-of-service violations and account security risks. Users attempting to shop via the assistant are met with popups warning that access by an unauthorized AI agent violates Amazon's conditions of use.
Amazon stated that third-party applications making purchases on behalf of users must operate transparently, disclose their agent identity, and respect platform policies, noting it previously requested that Meta exclude its site. Meta pushed back against the claims, emphasizing that Muse operates in secure environments and has no visibility into users' passwords or payment credentials.
The standoff highlights an emerging commercial struggle between dominant e-commerce platforms and autonomous AI agents. As consumer-facing assistants begin mediating product discovery, comparison, and checkout, platforms face direct threats to their advertising revenue, sponsored search listings, and customer relationships.
