In a May 28, 2026 guide on advertising in ChatGPT, StackAdapt says advertisers can buy ChatGPT ads either through OpenAI's self-serve Ads Manager Beta or through a technology partner such as StackAdapt. The company says buying through StackAdapt lets advertisers launch and manage ChatGPT placements with the same tools they use for other programmatic channels, while OpenAI handles ad delivery, relevance and placement. StackAdapt also says it supports reporting and conversion tracking for the channel. The guide describes the OpenAI program as an early test that began in the United States in February 2026 and has expanded to additional countries.
The details
- The guide lists ChatGPT ad availability in the US, Canada, Australia, New Zealand, the UK, Japan, South Korea, Mexico and Brazil, with launches planned in 31 European countries.
- Ads appear for logged-in Free and Go plan users, below a response, and not for Plus, Pro, Business, Enterprise or Education accounts or users under 18.
- Each ad includes brand name, favicon, headline, description and image, linking to a landing page.
- Reported metrics include impressions, clicks, click-through rate, average CPC, average CPM, spend and conversions.
- StackAdapt notes early access is generally better suited to industries with fewer regulatory restrictions, and some categories may be limited.
