Meta integrates Walmart, Gap, and Best Buy into Muse AI agent

Meta’s Muse AI agent can now shop at Walmart, Gap, and Best Buy on your behalf. The integration, announced by Meta executive Alexandr Wang, gives the AI assistant direct access to three of America’s largest retail chains, covering everything from groceries to electronics to apparel.

What Muse actually does

Muse launched on September 8, 2026, as Meta’s first standalone personal AI agent. The tool can send emails, book reservations, fill out forms, and make purchases, all operating within what Meta calls the Muse Secure VM, a sandboxed environment designed to keep user data and financial information protected.

The agent runs on Muse Spark 1.3, a model featuring a one-million-token context window.

For payments, Muse uses Stripe Link and generates single-use cards for each transaction. Meta has also partnered with Shopify and PayPal to broaden the payment infrastructure.

The service is available to US adults 18 and older. A free tier exists, but the real functionality lives in the paid plans: $20 per month for Power and $100 per month for Maximum. Access comes through a dedicated app, a web interface, and WhatsApp integration, with AI glasses functionality reportedly on the roadmap.

Early traction suggests real demand

The app secured between 2.5 and 2.8 million downloads in its first two weeks, consistently ranking at number one or two on the US iOS App Store charts.

Wang, who joined Meta from Scale AI in 2025 and serves as Chief AI Officer, has been pushing Muse through social media campaigns and television advertising. One initiative, the #MuseMoneyChallenge, positions the agent as a money-saving tool.

The bigger picture for retail

Amazon, which has built its empire on being the default shopping destination, now faces a scenario where Meta’s AI agent could redirect purchase decisions before a customer ever opens the Amazon app. Google Shopping faces a similar threat.

Meta’s AI infrastructure spending, projected to exceed $130 billion for the year, underscores how seriously the company is investing in this bet.

Meta has referenced a future model codenamed “Watermelon” that would succeed Spark 1.3, suggesting the current version is just the foundation.
