StackAdapt's ChatGPT ad operation method has leaked

According to a pitch deck obtained by ADWEEK, StackAdapt, together with OpenAI, is proposing a limited pilot program to advertisers for ads inside ChatGPT.

The core is targeting based on prompt relevance. It is positioned as a discovery layer that surfaces ads in contexts where users are researching or comparing products, with a structure presented as CPM $15 for niche inventory, rising to as much as $60 when competition increases.

The minimum spend to join the pilot is listed in the document as $50,000, but OpenAI stated that advertisers cannot directly select the $15 CPM themselves, and explained that the minimum spend threshold has also been adjusted. Industry sources say the current threshold is roughly in the $100,000-$150,000 range.

This material is based on the "OpenAI x StackAdapt Limited Pilot Program" pitch deck shared with some buyers on March 27, and was introduced as an early test aimed at enabling ads within ChatGPT.

The article also covers the background of OpenAI's expanding advertising business. OpenAI reportedly launched its ad pilot in February 2026 and reached an annualized revenue of $100 million within six weeks, and is said to have presented investors with a target of $100 billion in ad revenue by 2030.

The current ad formats are centered on Sponsored Product Cards that match conversation topics, and an Ads Manager that has begun rolling out to some pilot advertisers. OpenAI has also confirmed product card inventory partnerships with Etsy and Shopify.
