Instant Checkout in ChatGPT (Retired March 2026)

Instant Checkout was ChatGPT's in-conversation purchase feature, live from September 2025 to March 2026. OpenAI retired it in favour of discovery in ChatGPT with purchase on the merchant's site or inside a retailer's ChatGPT App.

What Is Instant Checkout?

Instant Checkout was OpenAI's in-conversation purchase feature for ChatGPT, branded "Buy it in ChatGPT." It was an early form of agentic commerce: shoppers could select, configure and buy a product inside the chat using stored payment credentials. OpenAI retired it in March 2026. Few merchants had gone live, and brands were wary of becoming anonymous fulfilment behind someone else's checkout. ChatGPT Shopping now works as discovery and recommendation, sending shoppers to the merchant's site, with in-conversation purchasing moving to retailer-built ChatGPT Apps.

The feature grew out of ChatGPT's product search, launched in late 2024. Instant Checkout launched in September 2025 with Etsy and Shopify merchants, was powered by the Agentic Commerce Protocol (ACP) and processed payments through Stripe.

OpenAI stated that "product recommendations are based on relevance, not enrollment status." That still holds: what gets recommended depends on how well the product information matches the shopper's question.

How Instant Checkout Worked (Historical)

When active, shoppers saw a Buy button on products from enabled merchants and completed the purchase without leaving ChatGPT.

Products from enabled merchants showed a "Buy" button beside the standard "Visit" link. The flow:

  1. Consumer selects a product from ChatGPT's recommendations
  2. ChatGPT displays product details: variants, sizes, colours, shipping options
  3. Consumer selects options and reviews the order
  4. Payment credentials (stored in ChatGPT for Plus/Pro users) are pre-filled
  5. Consumer confirms the purchase
  6. Order confirmation appears in the chat with tracking details

Everything happened inside ChatGPT. Stripe processed payment, so ChatGPT never held card details. The merchant fulfilled the order as any other.

What Merchants Need Now

To appear in ChatGPT Shopping today you need products in ChatGPT's index through a complete feed, and product pages that answer what shoppers ask.

With checkout back on the merchant's site, the merchant's job is being found and chosen:

  • Products in ChatGPT's index, through the OpenAI product feed or a commerce platform that submits it for you
  • Complete attributes, accurate price and stock, and descriptions written for the questions shoppers ask
  • A product page that converts once the shopper clicks through, since that is where the sale now closes

Fees: appearing in ChatGPT Shopping is free. The transaction fee charged during the Instant Checkout period no longer applies. Normal payment processing applies on your own site.

FAQ

Does enrollment affect which products ChatGPT recommends?+
No. Recommendations are based on relevance to the shopper's question and the quality of the product information, not on enrollment or payment status.
Was there a fee for Instant Checkout?+
OpenAI charged a transaction fee on Instant Checkout purchases while the feature was live. It no longer applies. Appearing in ChatGPT Shopping is free.
How does ChatGPT Shopping work now?+
ChatGPT recommends products from its index and sends shoppers to the merchant's site to buy. Retailers that want in-conversation purchasing can build a ChatGPT App. Either way, the merchant keeps the customer relationship, login, loyalty and data.
