ChatGPT Is Transforming Shopping with Instant Checkout and Agentic Commerce Protocol

Imagine Shopping Directly in Your Chat

OpenAI’s Instant Checkout, powered by the Agentic Commerce Protocol (ACP) in partnership with Stripe, is making this seamless experience possible within ChatGPT. Merchants and developers now have the opportunity to connect with millions of potential buyers right at the source of product discovery inside the chat itself.

Connecting with Shoppers Where It Counts

ChatGPT is quickly becoming a preferred destination for product recommendations. With Instant Checkout, merchants can capitalize on this demand, allowing users to complete purchases instantly within their chat window. This integration not only streamlines the buyer’s journey but also keeps merchants in control of fulfillment, customer relationships, and payment processing.

Level Playing Field and Transparent Discovery

Unlike traditional marketplaces, products in ChatGPT are surfaced based on natural-language relevance, not advertising budgets or exclusive partnerships. Merchants incur only a modest transaction fee when a sale is made, which is refunded for returned items. This approach encourages high-quality listings and ensures fair competition among sellers.

How the ChatGPT Shopping Experience Works

  • Natural Search: Shoppers describe what they’re looking for, such as “a ceramic housewarming gift under $100” and ChatGPT delivers curated, relevant options from across the web.

  • Easy Comparison: Buyers can compare multiple sellers, price points, and variations at a glance. Merchants are ranked by factors like availability, price, and whether they are the primary source. Enabling Instant Checkout provides a smoother, faster path to purchase.

  • Direct Purchase: Customers confirm orders and payment details right in ChatGPT. Merchants retain oversight of order acceptance, payment, and fulfillment using their existing tools.

  • Flexible Payments: Buyers can pay with credit cards, Apple Pay, Google Pay, or Link by Stripe. Plus and Pro users benefit from pre-filled payment and shipping information for even quicker transactions.

  • Post-Purchase Management: Merchants handle confirmation, shipping, returns, and support. Shoppers can track their orders in ChatGPT and directly on the merchant’s site, but are not automatically enrolled in marketing lists.

Agentic Commerce Protocol: The Engine Behind AI Shopping

The ACP is an open standard that enables smooth transactions between AI agents and businesses. It’s designed for easy integration, Stripe users can add payments with minimal effort, and other platforms can connect via Stripe’s Shared Payment Token API or the ACP Delegated Payments Spec. Leading marketplaces like Etsy are already on board, with Shopify integration and broader adoption on the horizon. ACP is set to become the backbone of AI-driven commerce.

How Merchants Can Join the ChatGPT Commerce Ecosystem

Merchants interested in featuring their products in ChatGPT can start by applying through OpenAI’s portal. The process involves:

  • Submitting an application via OpenAI’s merchant portal

  • Preparing a product feed that meets OpenAI’s requirements

  • Integrating with ACP (or simply joining if you’re already on Etsy or Shopify with no extra integration needed)

Currently, Instant Checkout is open to US merchants, with plans to expand soon. OpenAI reviews and onboards merchants on a rolling basis, helping maintain a high-quality, curated shopping experience for users.

Embrace AI-Driven Commerce

By adopting ChatGPT’s Instant Checkout and ACP, merchants can turn conversations into sales while keeping control over their brand and customer experience. As AI-powered shopping becomes mainstream, those who move early will gain an advantage by meeting customers at the moment of inspiration and making it effortless to buy.
