Instant Checkout (ChatGPT) - Discontinued

Instant Checkout was OpenAI's in-conversation purchase feature for ChatGPT, branded as "Buy it in ChatGPT." It allowed consumers to select, configure, and purchase products within the chat interface using stored payment credentials. OpenAI discontinued the feature in March 2026, citing that brands did not want to become anonymous fulfillment centers. ChatGPT Shopping now operates as a discovery and recommendation engine, directing users to merchant websites to complete purchases.

The feature evolved from ChatGPT's product search capabilities that launched in late 2024. Early merchant integrations began in late 2025. OpenAI expanded the "Buy it in ChatGPT" experience to U.S. users in February 2026 but discontinued it in March 2026. The feature was powered by the Agentic Commerce Protocol (ACP) and processes payments through Stripe's infrastructure.

OpenAI has stated that "Product recommendations are based on relevance, not enrollment status" — meaning enrollment does not influence which products ChatGPT recommends. Product recommendations remain relevance-based (OpenAI, Feb 2026).

When Instant Checkout was active, products from enabled merchants displayed a "Buy" button alongside the standard "Visit" link. The purchase flow:

1. Consumer selects a product from ChatGPT's recommendations
2. ChatGPT displays product details — variants, sizes, colors, 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

The entire process happens inside ChatGPT. Payment is processed by Stripe — ChatGPT does not store or access card details directly. The merchant handles fulfillment as they would any other order.

Requirements:

• Products must be in ChatGPT's product index (Shopify merchants are auto-included)
• ACP integration, typically through Stripe's Agentic Commerce Suite
• Product feed compliant with OpenAI's commerce feed specification
• U.S.-based merchant (international expansion timeline not yet announced)

Fees: Product discovery in ChatGPT Shopping is free for merchants. The 4% transaction fee that existed during the Instant Checkout era (January-March 2026) is no longer charged. Standard payment processing fees apply when customers purchase on the merchant's website.

Live merchants (as of Feb 2026): Etsy, 1M+ Shopify merchants (auto-enrolled), SKIMS, Glossier, Spanx, Vuori, URBN brands, with Walmart and Target partnerships announced.
