StackAdapt, OpenAI's advertising partner, is now selling ChatGPT ad placements based on the content of user prompts. The strategy targets ads to users based on what they're asking the AI.

According to a leaked internal presentation obtained by Adweek, StackAdapt plans to offer advertisers access to ChatGPT users through "prompt relevance" targeting. Ads would be served based on the specific queries users enter into the chatbot. The approach represents a new monetization avenue for OpenAI, allowing brands to reach users at moments when they're searching for particular information or solutions. An advertiser could theoretically target users asking about fitness routines, travel plans, or technical problems. The strategy generated discussion on Hacker News, where users raised questions about privacy implications and the transparency of ad placement within ChatGPT. OpenAI has not yet publicly detailed how this targeting works or what safeguards protect user data. The move signals OpenAI's intention to build out ChatGPT's ad infrastructure beyond simple display placements, moving toward behavioral and contextual targeting similar to traditional search advertising.
