Meta's Muse and your Shopify store: you're probably already in it. Being picked is a different question.

Short answer: if you sell on Shopify to the US, Canada or Mexico, your products can probably already be found and bought in Meta's Muse, with no action from you. Shopify makes eligible products discoverable through Shopify Catalog, and checkout inside Muse is on by default. There's no extra fee. What nobody outside Meta can tell you yet is which products Muse recommends, and why.

This post covers what's documented, the three settings worth checking this week, and what's known (and not known) about how Muse chooses.

What Muse is

Meta launched Muse on September 8, 2026. It's an AI agent that runs as its own app and inside WhatsApp, and it can act on things a person saves on Instagram. Shopping is one of the things it does: a shopper can ask it for a product, and it can show options and complete the purchase.

Meta has named retail partners including Walmart, Best Buy, Sephora, Ulta and Wayfair, and said the Shopify catalog is included. That last part is the one that matters to most independent brands.

Is my Shopify store in Muse?

Probably, if three things are true:

• You sell to customers in the United States, Canada or Mexico.
• Your products are eligible for Shopify Catalog.
• You've agreed to Shopify's Agentic Storefronts terms.

Shopify's help page puts it plainly: "You don't need to do anything for your products to be discovered by Meta through Shopify Catalog." And for checkout: "Purchasing in direct checkouts is activated by default for eligible stores."

On fees, Shopify says: "There are no fees associated with selling in Meta's direct checkout. You pay only your standard payment processing fees." You stay the merchant of record, so fulfilment, returns and support are still yours.

Three things to check this week

1. Is it switched on, and do you want it to be? In your Shopify admin: Sales channels → Agentic. Turn off "Allow Shopify to manage for me", then open "Meta AI and Muse". Direct checkout has its own toggle there. Most brands will want to leave it on. The point is to know it's on.

2. Can your best seller actually be bought there? Meta's direct checkout doesn't support subscriptions, product bundles, customizable products, B2B-only products, local delivery or pickup, or products that require the shopper to sign in. If your hero product is a bundle or a subscription, it may not be purchasable inside Muse. A single-item version of the same product can be.

3. Where will the sales show up? In Shopify, as orders attributed to Meta. Not in Google Analytics: Shopify says "Google Analytics and custom pixels won't fire in Meta's direct checkout." Only server-to-server checkout events fire. If your weekly report starts in GA4, Muse sales won't be in it. Check your Shopify orders by channel instead.

How does Muse decide what to recommend?

Meta hasn't published how Muse ranks products. The most detailed public look so far comes from Profound, an AI search analytics company, which ran 50 prompts from one retail category through Muse and published the results on October 2. It calls this "a small, exploratory sample", so treat it as early evidence, not rules:

• Muse searches two ways at once. It queries Meta's product catalog (the one behind shopping on Instagram and Facebook) and, in parallel, opens a browser to visit merchant sites.
• The catalog isn't the whole story. In Profound's sample, the catalog returned roughly 60 products from 30 merchant sites, while the browser typically visited 3 sites and returned 4 products. The final set was typically 6 products: 2 from the catalog and 4 from the browser.

If that pattern holds, being in the catalog gets you considered, and what Muse finds when it browses helps decide whether you're picked. Profound's suggestion, which is its inference and not Meta's guidance, is to make product pages easy to read: intended uses, compatibility, dimensions, materials and limitations where a visitor can find them.

Can I see Muse visiting my store?

Not with standard tools. Meta's crawler documentation doesn't list Muse, and Meta says that when Muse browses the internet, "it will appear as your activity", meaning the shopper's. One bot-security vendor, HUMAN, has published figures on Muse traffic it identified, but nothing in Shopify or GA4 labels it today.

What this means for a small Shopify brand

Muse is one of several AI assistants that now help shoppers decide and, increasingly, buy. ChatGPT, Google's Gemini and AI Mode, Microsoft Copilot and Perplexity all have shopping features of their own. The setup work is mostly done for you by Shopify. The part that isn't:

• Make sure the products you most want to sell can be bought through agent checkouts (check the unsupported list above).
• Report AI-assisted sales from Shopify orders, not GA4 alone.
• Ask Muse the questions your customers ask in your category, and note which brands it picks (Meta says Muse is available in the US and Canada for now). It takes ten minutes and no tool.
• Watch what AI assistants say when shoppers ask about your category, because that's where picking happens.

Being enrolled isn't the same as being picked.
