ChatGPT as shopping layer
A market advisory claims ChatGPT is acting as a shopping assistant with roughly 900 million weekly active shopping sessions, and many merchants' product feeds aren't structured for that kind of conversational discovery. The write-up argues merchants need product information that survives AI summarisation—clear attributes, unambiguous specs and machine-readable signals—so AI can match intent like 'waterproof hiking boots under $150' to the right SKUs. That framing treats ChatGPT as an additional product-discovery surface alongside Google and marketplace feeds. (upgrowth.in)
ChatGPT is turning into a product-discovery channel, and OpenAI is now building merchant tools around that shift. (openai.com) OpenAI said on March 24, 2026 that ChatGPT now supports richer, more visual shopping, including side-by-side comparisons, image-led browsing, and conversational refinement by budget, preferences, and constraints. The company said the rollout covers Free, Go, Plus, and Pro users. (openai.com) That followed a November 24, 2025 launch of “shopping research,” a mode that asks follow-up questions, searches the web, and builds buyer’s guides for prompts like “the quietest cordless stick vacuum” or “a stroller” with specific trade-offs. OpenAI said “hundreds of millions of people” already use ChatGPT to find, understand, and compare products. (openai.com) The mechanics are different from a keyword search box. OpenAI’s help documentation says ChatGPT decides whether a query has shopping intent, then selects products using structured metadata from merchants and third-party providers, plus price, reviews, and other context from the conversation. (help.openai.com) That means merchants are no longer writing only for a human shopper scanning a product page. They are also writing for a system that may compress several feeds, reviews, and descriptions into one short answer or carousel. (help.openai.com) OpenAI has started formalizing what that machine-readable layer should look like. Its developer documentation says merchants can upload a structured product feed so ChatGPT can index products with current price, availability, seller context, product identifiers, descriptions, media, and variants such as color or size. (developers.openai.com) The file spec lists 56 fields, including 27 required ones in the current draft, and says stable identifiers and variant data are needed so products can be displayed correctly and matched over time. In plain terms, “waterproof,” “women’s,” “size 8,” and “under $150” need to exist as clean data, not just marketing copy. (developers.openai.com) OpenAI is also pushing beyond discovery into checkout. In a separate product post, the company said ChatGPT can show organic, unsponsored product results and, for participating merchants, let users complete purchases inside the chat through Instant Checkout. (openai.com) OpenAI said merchants pay a fee on completed purchases, but that Instant Checkout does not change ranking, and product results are still selected on relevance. When several merchants sell the same item, OpenAI said ChatGPT weighs factors including availability, price, quality, primary-seller status, and whether Instant Checkout is enabled. (openai.com) The independent claim of roughly 900 million weekly shopping sessions comes from a marketing advisory, not from OpenAI. OpenAI’s own public figure is broader: the company said in a business report published in February 2026 that ChatGPT has “over 700 million weekly active users,” without breaking out shopping activity. (upgrowth.in) (openai.com) The practical change is that ChatGPT now sits alongside search engines, retailer sites, and marketplaces as another place where product data gets interpreted before a shopper clicks. The merchants that show up cleanly are likely to be the ones whose catalogs survive that interpretation intact. (openai.com) (developers.openai.com)
