Meta's Muse Can Now Buy From Shopify Stores. Amazon Blocked It the Same Weekend.

"We want to give our users access to a wide range of stores to find the absolute perfect products."
Meta's Muse personal AI agent can now complete purchases on behalf of users across all Shopify-powered stores, announced on September 21, making it the first major personal AI agent to integrate agentic checkout at the scale of Shopify's merchant network.
The integration works through Shop Pay, Shopify's accelerated checkout service that stores payment and shipping details for faster transactions, meaning a Muse user can ask the agent to find and buy a product, and Muse completes the transaction through Shop Pay without the user navigating to a retailer's website or entering payment details.
Shopify CEO Tobi Lütke described it on X as enabling "agentic checkout with Shop Pay on all Shopify stores," covering the full breadth of Shopify's merchant base rather than a subset of participating retailers.
The same weekend, Amazon blocked Muse from conducting shopping through its platform. "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," an Amazon spokesperson told MarketWatch.
Amazon generates approximately 10% of its revenue from advertising, a business that agentic shopping agents directly threaten by intercepting the product discovery and comparison stages that advertising currently monetizes.
The Amazon and Shopify responses to Muse represent two distinct strategic positions on the same underlying commercial question: does an AI agent that completes purchases on a user's behalf make an e-commerce platform more or less valuable?
Amazon's position is that it is a threat, specifically to the advertising revenue that depends on consumers discovering products through Amazon's own search and recommendation surfaces.
Pivotal Research analyst Jeff Wlodarczak described Amazon's block as "one of the first clear signs that autonomous AI agents have the potential to significantly disrupt shopping-related advertising."
He added that once users adopt a capable personal agent across email, calendar, research, and shopping, switching costs rise and the personal agent becomes the default interface, which is exactly the scenario Amazon's advertising business cannot afford.
Shopify's position is the opposite. Deutsche Bank analyst Bhavin Shah said the partnership with Muse helps refute the recent bear thesis that AI agents could disintermediate Shopify and its large payments business, arguing that AI agents make it easier to find and buy products, with Shopify's Shop Pay and merchant catalog becoming infrastructure that agents depend on rather than competition they route around.
"We want to give our users access to a wide range of stores to find the absolute perfect products," said Alexandr Wang, Meta's Chief AI Officer.
Muse launched earlier in September and within two weeks had overtaken ChatGPT, Kalshi, and Polymarket on the Apple App Store. Zuckerberg described the Shopify deal as the first of more commerce partnerships coming.
