OpenAI appears to be preparing to extend its advertising business in ChatGPT into Europe by updating the technical foundations of its conversion tracking pixel. The revised pixel includes a consent management system that allows advertisers to request permission before tracking users and to stop tracking if that permission is withdrawn. Advertisers can also flag or exclude certain actions, such as a purchase or a sign-up, from measurement. The pixel now collects a country field as well, indicating that OpenAI is designing its ad tools with jurisdiction-specific data handling in mind.
Those changes align closely with European privacy requirements, where explicit consent must be obtained before a tracking pixel can be activated and users must be able to revoke that consent at any time. In the U.S., privacy rules generally work on an opt-out basis, so businesses do not need permission before tracking begins. Industry executives said the architecture of consent transmission remains one of the hardest compliance problems in advertising technology because consent signals must pass accurately through every partner in an advertiser’s tech stack. That makes OpenAI’s approach especially important as regulators and privacy groups pay closer attention to how platforms monetize user attention in the Artificial Intelligence era.
The pixel’s arrival follows earlier signs that OpenAI was developing ad measurement tools and reflects a broader shift away from third-party cookies. Those cookies have already been blocked by Safari and Firefox, pushing advertisers toward server-to-server measurement systems. OpenAI built its infrastructure in that style from the outset, but the company’s conversion pixel is still early. Early advertisers in ChatGPT’s ads pilot have no pixel at all. They were manually tracking how much traffic their ads drove using rough methods and spreadsheets. The pixel is still being rolled out, and in its current form only measures the last action a user takes before converting such as clicking on an ad. More sophisticated measurement, like crediting ads that a user saw but didn’t click or adjusting how far back in time a conversion can be attributed, is planned but without a confirmed timeline.
For now, the tool operates more like a managed service than a self-serve platform. OpenAI builds the pixel around each advertiser’s measurement needs and provides implementation support, an arrangement that may need to evolve if the ad business is to scale. As things stand, OpenAI’s ChatGPT ad pilot is extending beyond the U.S. and will soon include Canada, Australia and New Zealand in the coming weeks. Digiday also reported last week that the company is looking for execs for its ads team in London and Tokyo.
