Shopify is opening its product catalog to any AI agent, not just Meta's Muse. The company announced that shoppers can now configure AI agents to purchase products on their behalf, giving agents access to over a billion listings in Shopify's catalog, which includes items both on and off Shopify storefronts.

The feature works through Shopify's Shop app. Customers connect an agent to their Shop account, and the agent can browse and recommend products. Checkout uses one-click Shop Pay within the conversation, and orders are funneled back to the Shop app. Buyers must approve each purchase and can set rules like budget guardrails or fast-shipping preferences.

The move expands Shopify's agentic commerce ambitions beyond its September partnership with Meta's Muse. By opening the catalog to any agent without a partnership integration, Shopify positions itself as a neutral platform in the emerging AI shopping race. The source notes that e-commerce has become a battleground, with Google and Amazon investing in AI-driven shopping tools, and disputes over whether agents should shop on behalf of customers.
