Shopify has stopped treating AI shopping as something merchants opt into. In its Spring '26 Edition, published on 17 June with more than 150 updates, the company switched on its agentic-commerce infrastructure by default for eligible stores, meaning their products are now structured and distributed to AI assistants whether or not the merchant set anything up. Two components do the work: Shopify Catalog, which standardises product data into a queryable dataset, and the Universal Commerce Protocol, the open standard Shopify co-developed with Google for how AI agents transact with merchants.

The change matters because the place where shoppers begin a purchase is moving. As buyers increasingly start in ChatGPT, Microsoft Copilot, Google's AI Mode and the Gemini app, the discoverability problem shifts from ranking a storefront page to making product data legible to an agent. By enabling Catalog and the protocol by default, Shopify has made that exposure the baseline for its merchant base rather than an advanced setting — and handed marketing teams a new surface to manage, measure and, where they choose, switch off.

What is now switched on by default?

Shopify Catalog and the Universal Commerce Protocol are now active for eligible merchants with no manual feeds or extra apps. Catalog syndicates product details — titles, variants, attributes such as size and colour — to ChatGPT, Copilot, Google AI Mode, the Gemini app and Shopify's own Shop app, so agents can find and present items accurately. The protocol covers the full path from discovery to checkout and, according to Shopify, carries backing from Amazon, Meta, Microsoft, Salesforce, Stripe, Etsy, Target and Wayfair, with payment networks including Visa, Mastercard and American Express endorsing the wider standard.

The release also opens the infrastructure to developers. The Catalog API now requires only an API key rather than approval, and adds image and multimodal search plus richer product metadata, so third parties can build shopping experiences on top of millions of merchants' listings. Shopify frames the protocol as an open standard rather than a proprietary lock-in, co-developed with Google and built in layers so merchants implement only the capabilities they support. The Spring '26 Edition builds on the protocol Shopify and Google first revealed on 11 January and on the Agentic Storefronts work introduced in December.

How can marketers see what AI channels are doing?

Marketers track AI-channel performance through a new Agentic Storefronts dashboard inside the Shopify admin. It lets merchants manage every connected AI surface from one place and view orders, sales and conversions attributed to ChatGPT, Copilot, Google AI Mode, the Gemini app and Shop together — closing part of the measurement gap that has made AI-driven sales hard to credit. A search-intelligence view shows which AI queries in a merchant's category they already surface for and which they miss, and Shopify's assistant, Sidekick, suggests fixes such as sharper product titles when items appear in AI conversations but fail to convert.

Shopify's case for default exposure rests partly on a conversion claim: the company says AI searches powered by Catalog convert at twice the rate of those built on scraped data, attributing the gap to cleaner, more current structured data. That figure is the company's own and has not been independently verified, and Shopify's supporting examples — such as a red-light-therapy brand crediting AI channels with 3.2% of total revenue in one month — are vendor-stated. The direction is clearer than the magnitude: structured product data is becoming the unit that decides whether a brand appears in an agent's answer.

What do marketing teams need to do now?

Marketing teams on Shopify face two immediate jobs: tidy their product data and meet a hard platform deadline. Because agents rely on structured attributes to surface and describe products, inconsistent taxonomies, thin descriptions and poor images now translate directly into weaker visibility in AI channels — making catalogue hygiene a marketing concern rather than a back-office one. Separately, Shopify Scripts stops running on 30 June, requiring merchants still using it to migrate custom checkout logic to Shopify Functions before the cut-off.

There is a trade-off worth weighing alongside the upside. When a purchase completes inside an AI assistant, the buyer may never see a brand's landing page, testimonials or merchandising, compressing the funnel for stores whose conversion depends on that storytelling. For commodity products bought on specification, agent-channel exposure is largely upside; for brands that sell through experience, default visibility comes with less control over how the brand is presented. Shopify's settings allow merchants to manage which channels are active, leaving the decision — and the data hygiene it rewards — with the marketing team.

Shopify said more advertising channels, including Microsoft Advertising, ChatGPT Ads and Snapchat, are coming to its automated campaign tools, and that developers will soon be able to earn revenue when their Catalog-powered experiences drive sales. The open question is how much of the buying journey shoppers will hand to agents — and how quickly the attribution data in the new dashboard gives marketers a defensible answer.
