The OpenAI product discovery program waitlist is the application queue for merchants that want to share product data with ChatGPT so their products can appear in shopping and product discovery experiences. On OpenAI’s merchant page, the company says merchants can apply to share product data and participate in shopping experiences in ChatGPT, and that if a business has already applied, it is on the waitlist. OpenAI also says sellers using Shopify or Etsy already have catalog integration and do not need a separate application. That matters because the waitlist is not a general marketing signup. It is part of OpenAI’s commerce infrastructure, which is built around product feeds and the Agentic Commerce Protocol, or ACP. The confusion usually starts when merchants assume “waitlist” means paid ads, marketplace listings, or a guaranteed placement program. Based on OpenAI’s current materials, it is better understood as an onboarding path for merchants who want ChatGPT to ingest their catalog data for product discovery.
