What Is Instant Checkout?
Instant Checkout is ChatGPT's "Buy" button that lets consumers complete purchases entirely inside a conversation without visiting external websites.
Instant Checkout is OpenAI's in-conversation purchase feature for ChatGPT, branded as "Buy it in ChatGPT." It allows consumers to select, configure, and purchase products entirely within the chat interface using stored payment credentials, without visiting the merchant's website.
The feature evolved from ChatGPT's product search capabilities that launched in late 2024. Early merchant integrations began in late 2025, with the 4% transaction fee introduced in January 2026. OpenAI expanded the "Buy it in ChatGPT" experience to all U.S. users -- Free, Plus, and Pro tiers -- in February 2026. Instant Checkout is powered by the Agentic Commerce Protocol (ACP) and processes payments through Stripe's infrastructure.
OpenAI has stated that "Instant Checkout items are not preferred in product results" -- meaning enrollment does not influence which products ChatGPT recommends. Product recommendations remain relevance-based (OpenAI, Feb 2026).
How Instant Checkout Works for Consumers
Consumers see a "Buy" button on recommended products, confirm details, and complete purchase without leaving ChatGPT.
When a ChatGPT user asks for product recommendations, products from Instant Checkout-enabled merchants display a "Buy" button alongside the standard "Visit" link. The purchase flow:
- Consumer selects a product from ChatGPT's recommendations
- ChatGPT displays product details -- variants, sizes, colors, shipping options
- Consumer selects options and reviews the order
- Payment credentials (stored in ChatGPT for Plus/Pro users) are pre-filled
- Consumer confirms the purchase
- 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.
Merchant Requirements and Fees
Merchants need ACP integration (typically via Stripe), a compliant product feed, and pay a 4% transaction fee to OpenAI.
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: OpenAI charges a 4% transaction fee on completed Instant Checkout purchases. This is in addition to standard Stripe payment processing fees. The fee structure is comparable to marketplace fees on platforms like Amazon (8-15%) or Etsy (6.5%), making it relatively competitive for AI-driven sales.
Live merchants (as of Feb 2026): Etsy, 1M+ Shopify merchants (auto-enrolled), SKIMS, Glossier, Spanx, Vuori, URBN brands, with Walmart and Target partnerships announced.
