OpenAI and Instacart are introducing a fully integrated grocery shopping app within ChatGPT, allowing users to transition seamlessly from meal ideas to a completed Instacart order without leaving the conversation. Instacart is the first app in ChatGPT’s ecosystem to offer Instant Checkout directly in chat, utilizing the Agentic Commerce Protocol and powered by Stripe payments.
Stripe is partnering with @Instacart to enable direct checkout in ChatGPT.

In this new process, a prompt like “Help me shop for apple pie ingredients on Instacart” activates the Instacart app. This app connects to a signed-in Instacart account, retrieves inventory from local retailers, and assembles a cart for review. Users can then complete their payment within ChatGPT using a standard card form, with support for Apple Pay and Google Pay planned for future updates. This feature is currently available on desktop and mobile web, with Instant Checkout set to expand to iOS and Android apps next.
Behind the scenes, the Agentic Commerce Protocol, co-developed by OpenAI and Stripe, serves as an open standard for programmatic commerce flows. It enables AI agents to manage cart states, utilize merchant tools, and coordinate checkout processes while ensuring that payment credentials remain secure with the provider. Instacart’s launch represents one of the earliest large-scale implementations of this protocol within ChatGPT.
Instacart has been an early collaborator on OpenAI’s Operator agent and already employs OpenAI APIs, ChatGPT Enterprise, and a Codex-based coding agent to enhance recommendations and internal workflows. This new phase of the partnership extends that technology outward to shoppers and retailers, positioning Instacart as a leading commerce partner as OpenAI advances its agents from mere suggestions to real-world transactions across its enterprise ecosystem.
