OpenAI and ACP: What ChatGPT Commerce Means for Merchants

OpenAI dropped its own ChatGPT checkout and bet on product discovery. Here is what ACP does for merchants now, and what to actually do about it.

OpenAI's agentic commerce story has a plot twist that confused a lot of merchants: the company that launched in-chat checkout quietly stepped away from running it. If you are trying to figure out what to actually do about ChatGPT and your store, that twist matters. Let me walk through what happened and where it leaves you.

The short history

In September 2025, OpenAI and Stripe launched ACP and, with it, Instant Checkout inside ChatGPT. For a while, the pitch was: a user buys directly in the chat, and ChatGPT handles the transaction.

Then, on 24 March 2026, OpenAI changed direction. In its own words, that first version "did not offer the level of flexibility" it wanted. So it stopped trying to own the whole checkout and refocused ChatGPT on product discovery instead.

That is the twist. The headline feature became a stepping stone.

What ChatGPT commerce is now

Here is the current shape, and it is actually simpler for merchants than the original.

ChatGPT is now a discovery surface. It shows products, lets people compare them side by side, search by image, and refine conversationally — and those richer discovery features rolled out to all Free, Go, Plus, and Pro users in March 2026. ACP is the connective layer: merchants share product feeds and promotions through it so their catalogs can appear in ChatGPT.

The purchase itself mostly happens on the merchant's own store, through an in-app browser — or inside a dedicated ChatGPT app for merchants who build one. The merchant stays in control of checkout. For a lot of retailers, that is a relief.

How a merchant actually appears

There are a few paths in, and the easiest one covers a huge number of stores automatically:

  • Shopify merchants are covered by Shopify Catalog. No extra work from the individual merchant — their products can show up in ChatGPT through the existing Shopify integration.
  • Feed providers. Catalogs can flow in through third parties such as Salesforce and Stripe.
  • ChatGPT apps. Merchants who want a deeper, native experience can build their own app inside ChatGPT. Walmart did exactly this — a full in-ChatGPT app with account linking, loyalty, and Walmart payments.

Retailers already integrated for discovery include Target, Sephora, Nordstrom, Lowe's, Best Buy, The Home Depot, and Wayfair. That is not a pilot list; those are large, serious stores.

What this means for you

Strip away the drama and the merchant to-do list is clear:

  1. Your product data has to be agent-ready. Discovery runs on your feed. If the feed is thin, stale, or wrong, you either do not show up or you show up wrong. This is the whole reason I keep harping on agent-ready product data — it is now table stakes for being found in ChatGPT.
  2. You probably do not need to rebuild checkout. Since the purchase lands on your store, your existing checkout still works. The job is being discoverable, not re-plumbing payments.
  3. Decide if a ChatGPT app is worth it. For most, the feed path is enough. For big retailers who want loyalty and native payments, an app (like Walmart's) may pay off. Most stores should start with the feed.

The honest read

I think OpenAI's retreat from owning checkout was the right call, and a useful signal for everyone building here. Owning the entire transaction — discovery, cart, payment, disputes — is genuinely hard, and even OpenAI decided the merchant should keep the parts merchants are good at.

The lesson generalises: the agent surface wins by being a great front door, not by swallowing the whole store. Discovery is where ChatGPT adds value today. Checkout, for now, stays closer to the merchant. If you plan around that, you will not be caught out by the next twist.
