OpenAI is rebuilding ChatGPT into a place people shop, not just chat. Its latest move expands the Agentic Commerce Protocol (ACP) into the discovery stage, so shoppers can browse products visually, compare options side by side, and refine what they want in conversation before they ever land on a retailer's site. For brands, the checkout button is no longer the front door. The product card inside an AI answer is.
That shift is already underway. People increasingly open ChatGPT to explore, compare, and decide what to buy, and OpenAI is now making that experience richer: visual browsing, image-based inspiration, side-by-side comparison of price, reviews, and features, and results that update in seconds instead of hours of tab-hopping. ACP is the connective layer that lets merchants feed this experience directly.
Key takeaways
- OpenAI is extending the Agentic Commerce Protocol (ACP) from checkout into product discovery, so merchants can share catalogs and promotions that surface as visual, comparable product cards inside ChatGPT. - Major retailers including Target, Sephora, Nordstrom, Lowe's, Best Buy, Home Depot, and Wayfair are already integrated, and ACP supports delivery paths through third parties like Salesforce and Stripe. - Shopify merchants get in without lifting a finger: product data flows into ChatGPT through the Shopify Catalog integration, so items can appear in relevant conversations with no extra work per merchant. - Merchants keep flexibility, including the option to run their own checkout rather than complete the purchase inside ChatGPT. - For GEO, this is the moment the AI shelf becomes a real sales channel. If your product isn't structured to appear as a card, with clean price, reviews, and attributes, an AI assistant simply recommends someone else, and you never see the impression you lost.
From answers to a shelf
Web shopping is easy when you already know what you want. The hard part is deciding, and that is exactly where ChatGPT is inserting itself. You describe what you're after, narrow it in conversation, and compare a handful of options that fit your budget and constraints. What used to mean reading the same "best of" lists across five tabs now happens in one thread.
The mechanics matter for brands. Under the expanded ACP, merchants share catalogs and promotions so their items show up complete and current inside ChatGPT. The protocol supports multiple fulfillment routes, including third-party providers such as Salesforce and Stripe, and lets merchants participate using systems they already run. OpenAI frames ACP as the foundation for broader AI-native commerce over time, including personalization, local availability, and estimated delivery windows.
The retailer lineup signals how fast this is moving. Target, Sephora, Nordstrom, Lowe's, Best Buy, Home Depot, and Wayfair are integrated. These incumbents already win the "best blender" or "best running shoe" query today, and now they have a structured pipe into the AI shelf.
