AI shopping answers are starting to point to products, not just brands. Can they read yours?
When someone asks ChatGPT for a product, the answer can be built from a product feed: a file a shop sends with each item’s ID, price, stock and delivery options. As of 28 June 2026, Shopify shares eligible US stores’ catalogues with AI assistants by default. Our read: if you sell products, what you control is how complete and current that feed is. How the assistant ranks your products stays its decision.

How it works
From your stockroom to an AI shopping answer
AI assistants don’t browse your shop like a person. They read a feed, field by field, and route the customer to a specific item.
You keep a catalogue
Every product you sell, with its variants, such as size or colour.
You send it as a feed
OpenAI’s specification lists the fields: product ID, GTIN (the barcode number) or MPN (the maker’s part number), price and sale price, availability, variant, shipping and pickup.
You choose where it may appear
Two flags in the product feed, is_eligible_search and is_eligible_checkout, say whether a product may show up in search and whether it may be bought there.
The assistant decides what to show
It assembles the answer from the feeds it can read. How it ranks and recommends products is not something a shop controls.
The platform’s decision
The customer lands on one product
Not your brand in general, but a specific item, at the price and stock your feed last said.
A wrong price or an out-of-date stock level doesn’t stay on your website. It travels into the answer.
What changed
Three public signals point the same way
They come from three different actors: the assistant, the shop platform and an independent trade publication.

Shopping answers read a product feed
OpenAI publishes a ChatGPT product feed specification. Shops submit the feed directly; the answers are assembled from it.
Shopify · from 24 March 2026
Catalogues switched on by default
Shopify’s Agentic Storefronts share eligible US stores’ catalogues with ChatGPT, Microsoft Copilot, Google AI Mode and Gemini through Shopify Catalog, Shopify’s route for passing a store’s catalogue on to those assistants. Shops can opt out.

Reported in the market, not only announced
The trade publication reported brands becoming shoppable inside ChatGPT through the Shopify integration.
Who this applies to
This is about shops and marketplaces that sell products with their own product codes. If that is you, it applies now.
A business that sells a service or serves an area without a product catalogue, such as a plumber or a hair salon, shouldn’t read too much into it.
Who does what
Your feed is yours. The ranking isn’t.
Our read: the question has moved from how often AI mentions your brand to whether it can identify, price and route to each of your products.
What you control
- Stable product IDs, with a GTIN or MPN for each item
- Correct price and sale price
- Stock that is current when an assistant reads it
- Shipping and pickup details
- Where each product may appear: search, checkout, or both
What the platform controls
- Whether your product is shown in an answer
- How products are ranked and recommended
- Which assistants read your catalogue, within the settings you choose
A complete, current feed is necessary, not sufficient. It doesn’t guarantee that a product is included, ranked or recommended.
What can still go wrong
A rejected or out-of-date field can quietly take a product out of answers, with nothing on your website looking wrong.
Tracking how often AI mentions your brand can hide which of your products are visible and which aren’t.
Participation figures that vendors publish are their own claims, not independent measurement.
No independent measurement yet shows this changing real purchases at scale.
What to do
Five things to check if you sell products
Start with the products that matter most to your sales.
Give every product a proper ID
Check that each item has a stable product ID and its GTIN or MPN, so an assistant can tell your products apart.
Keep price and stock in sync
Update the feed when price or stock changes, rather than waiting for an occasional crawl, so the answer matches your shelf.
Choose search and checkout on purpose
Use the two flags in your product feed to decide whether each product may appear in search and whether it may be bought there, instead of leaving the default.
If you sell on Shopify in the US, check the setting
Agentic Storefronts are on by default for eligible US stores. Look at what is shared, and opt out if that isn’t what you want. Not on Shopify? OpenAI’s product feed specification describes the feed a shop submits itself.
Track products, not just your name
Check which of your products actually appear in AI shopping answers, and watch for feed errors that drop them.

Being shown is one step. Being bought is the next.
Once assistants can route a customer to a product, fees and checkout terms start to matter too.
