OpenAI tests ad tracking

OpenAI is building a tool to tell advertisers whether a ChatGPT ad led to a sale, starting with a limited tracking-pixel pilot for some brands. (digiday.com, the-decoder.com) A tracking pixel is a small piece of code advertisers place on their own sites to record what users do after clicking or viewing an ad, such as a purchase or signup. Digiday reported OpenAI is testing that kind of measurement inside ChatGPT as it builds out ad products and pricing. (digiday.com) OpenAI began testing ads in ChatGPT in the United States on February 9, 2026, for logged-in adults on the Free and Go plans, and said ads would appear at the bottom of answers and be clearly labeled. The company said at launch that ads would not change ChatGPT’s answers and that users could dismiss them. (openai.com, openai.com, help.openai.com) The new measurement effort comes as OpenAI explores charging for ads based on clicks instead of only impressions, according to reports from The Information and follow-on coverage. Early advertiser tools have shown cost-per-click and cost-per-acquisition options as “coming soon,” while current buying has been more limited. (theinformation.com, letsdatascience.com, winbuzzer.com) OpenAI is trying to turn ChatGPT from a place where brands buy visibility into a place where they can measure performance, the same way they do on Google Search or Meta. Advertisers told Digiday and The Decoder that basic targeting and reporting are still thin, which makes it harder to move larger budgets. (digiday.com, the-decoder.com) OpenAI’s own ad materials pitch ChatGPT as a place where people move from research to decisions inside a conversation, not a search-results page. That framing helps explain why conversion tracking matters: advertisers want proof that a chat recommendation led to an action later on another site. (openai.com, digiday.com) The company has also published limits on where ads can appear. OpenAI’s ad policies say the initial test is focused on categories like lifestyle goods, local services, travel, experiences, digital products, and education, and excludes emotionally sensitive contexts such as mental health conversations. (openai.com) The ad business is still small and uneven by platform standards. The Decoder, citing reporting and company statements, said OpenAI told investors it expects $2.4 billion in ad revenue in 2026 and $11 billion in 2027, while OpenAI said its pilot reached more than $100 million in annual recurring revenue within six weeks. (the-decoder.com, openai.com) Advertisers say the harder problem is attribution, not just placement. A user might see an ad in ChatGPT, leave, and buy days later through direct traffic or search, which means OpenAI has to persuade marketers that its numbers capture ChatGPT’s role in that chain. (digiday.com, the-decoder.com) For now, OpenAI is building the plumbing first: ad slots, buying tools, pricing experiments, and a way to count what happens after a conversation. Whether marketers treat ChatGPT as a real performance channel will depend on whether those measurements hold up. (digiday.com, openai.com, the-decoder.com)
