Every eligible Shopify store is in Muse by default, with Shop Pay as a wallet
Tobi Lütke announced the partnership on 21 Sep; Shopify posted "Shop Pay is now available as a wallet in Muse" on 24 Sep UTC. Shopify's Help Center: product discovery is powered by Shopify Catalog, direct checkout is active by default for stores that ship to the US, Canada or Mexico, there are no fees beyond payment processing, orders are attributed to "Meta", and third-party pixels do not fire on direct checkout.

At Connect, Meta said Muse will earn a transaction fee over time, and named ten retailers
Zuckerberg: "we are standing behind this by making Muse free for a huge number of tokens with the expectation that over time we will profit by taking a small fee from transactions." No rate, date or payer was given. Meta's recap names Walmart, Best Buy, American Eagle Outfitters, DICK'S, Fanatics, Gap, Michael Kors, Sephora, Ulta and Wayfair as retailers it is adding; none is live yet.

Amazon began blocking Muse, citing its Conditions of Use
From Sunday night 20 Sep, Muse users hit a popup: "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed." Amazon said Meta had declined a request to remove Amazon from the experience; Meta has not commented. Amazon's Conditions of Use, updated 14 Aug 2026, require agents to identify themselves in the user agent string. No source reports any Muse path to an Amazon purchase.

Meta launched Muse, a personal agent that shops by driving a browser
Muse (muse.ai) takes a shopping brief, browses merchant sites in its own browser, returns product cards, and offers "Buy with Muse" or "Visit website". The buy path asks the shopper to create a one-time virtual card through Link by Stripe, so the merchant sees a guest checkout paid with a single-use credential.

In a four-agent test, Muse was the standout and it applied a discount on its own
Scot Wingo ran the same purchases through Muse, Instinct, GrokBot and Gemini Spark. Muse cleared the variant trap that caught Instinct, then "found a $20 off and processed my order with a stripe link". His read on why it matters: Meta has four products with more than a billion users each, so distribution is settled before the product is.
