When a shopper asks ChatGPT for “the best running shoes under $100,” a product carousel appears — and some stores are in it while yours may not be. Here is what OpenAI has actually published about how those products are chosen, what is still unknown, and the parts you can control.

OpenAI does not publish a full ranking algorithm, but its shopping help documentation and merchant announcements describe three pipelines feeding a shopping answer. None of them is “pay us and you appear.”
| Pipeline | What it is | Who controls it |
|---|---|---|
| Web search & crawling | ChatGPT search uses third-party search providers — Bing is the one OpenAI has named in its docs — plus OpenAI’s own crawler, OAI-SearchBot, which reads public retail pages directly. | You: crawlable pages, Bing indexing, on-page content. |
| Structured product metadata | OpenAI says shopping results are built from structured metadata — pricing, descriptions, reviews — from third-party providers and merchants (TechCrunch, Apr 2025). Merchants can also apply to submit a direct product feed via OpenAI’s merchant program. | You: schema, feed data quality, feed application. |
| Platform partnerships | Shopify announced in September 2025 that it powers product discovery in ChatGPT with real-time pricing, inventory, images, and variants for its merchants, built on the Agentic Commerce Protocol. Etsy joined at the same launch. | Partly you: clean catalog data flows through automatically. |
The model then does the last step itself: it interprets the shopper’s intent — budget, use case, constraints mentioned in the conversation, and (where enabled) ChatGPT’s memory of the user — and picks products it judges relevant. Since November 2025 there is also a deeper shopping research mode that builds a buyer’s-guide-style comparison before recommending.
Per OpenAI’s help center and its Instant Checkout announcement:
What OpenAI has not published: the weighting of any of these factors, how often product data is refreshed from crawls versus feeds, or category-level differences. Anyone selling you a guaranteed “rank #1 in ChatGPT” formula is guessing. We say that as a company that sells AI-visibility tooling: the honest play is to fix the checkable inputs, then measure.
Instant Checkout — buying inside ChatGPT — launched in September 2025 with Etsy sellers, with Shopify merchants following. By March 2026, CNBC and Search Engine Land reported OpenAI was moving away from the standalone in-chat checkout: shoppers were researching in ChatGPT but finishing purchases on merchant sites, so OpenAI is prioritizing discovery in ChatGPT with checkout on the retailer’s own site or app.
For a normal store this is good news. You do not need to win a checkout integration — you need ChatGPT to find, understand, and trust your product pages, because the click still lands on your storefront.
OAI-SearchBot or ChatGPT-User (OpenAI documents its bots here). Blocking GPTBot only opts you out of training data, but blocking the search bots removes you from ChatGPT’s live reading of your site.The same inputs feed other AI shopping surfaces too: Perplexity runs its own free merchant program for sharing product data, and Google’s AI results read the same schema. Fix the layer once, and every engine benefits.
Our free checker reads your public storefront the way an AI crawler does and scores the controllable inputs on this page: crawler access, structured data, content depth, and answer-readiness. No signup, about a minute. The Hatchloop app — launching on the Shopify App Store — then fixes the one-click gaps from inside your admin.
Partly. OpenAI’s documentation says ChatGPT search uses third-party search providers, and Bing is the provider OpenAI has named; OpenAI also runs its own crawler, OAI-SearchBot, and shopping answers additionally draw on structured product metadata and merchant feeds. So being indexable by Bing helps, but it is only one of several pipelines into ChatGPT shopping results.
No. OpenAI has stated that shopping product results are organic and not sponsored placements, and that they are ranked on relevance to the user. During the Instant Checkout era merchants paid a small fee on completed purchases, and OpenAI said that fee did not affect ranking. There is no pay-to-rank option for the product carousel.
Shopify and OpenAI announced a partnership in September 2025 under which Shopify powers product discovery in ChatGPT with real-time pricing, inventory, images, and variants, so Shopify catalogs are integrated at the platform level. Your job is to make sure your store’s data is worth surfacing: complete product descriptions, correct pricing and availability, Product schema on your pages, and no robots.txt rules blocking OpenAI’s crawlers. Merchants can also apply for a direct product feed through OpenAI’s merchant program.
In March 2026, CNBC and other outlets reported that OpenAI moved away from the standalone Instant Checkout experience inside ChatGPT and is prioritizing product discovery in ChatGPT with purchases completed on merchant sites or through retailer apps. For most stores this means ChatGPT influences the choice of product, and your own product page closes the sale.
