Are ChatGPT ads worth it? What 73,720 placements reveal
ChatGPT ads work in categories where buyers comparison-shop inside the assistant and lose money everywhere else. The data shows where the line sits.
0.7% of advertisers control about 32% of all ChatGPT ad placements. The surface is concentrated, the leaders are enterprise software and fintech, and consumer categories are still mostly empty.
Are ChatGPT ads worth it for your brand?
ChatGPT ads are worth it for some brands and a waste of money for others. The deciding factor is category. In Enterprise & Fintech, SaaS & Productivity, and Real Estate, brands are spending real budget and competing for attention. In Beauty & Skincare, Pet Care, and Insurance, the surface is thin and few prompts trigger commercial responses. We track 2,210 advertisers across 73,720 placements, and the data shows a small group of mostly B2B software and financial brands capturing most of the volume. Whether ChatGPT ads are worth it for you depends on whether your buyers are already asking ChatGPT the questions your product answers.
What are ChatGPT ads?
ChatGPT ads are sponsored recommendations that appear in ChatGPT's answers when a user asks a question with commercial intent. OpenAI began testing them in 2025, and they look different from Google or Meta ads. There is no keyword auction, no search results page, and no scrollable feed. The ad is woven into the assistant's reply, labeled as sponsored, and tied to the specific prompt that triggered it. That structure matters because it means buying ChatGPT ads is less about bidding on keywords and more about winning inclusion in the answers your buyers are already reading.
Across our tracked inventory, 2,210 advertisers have run 7,181 distinct ads that together generated 73,720 placements across 58 product categories. The gap between advertisers and ads, roughly three ads per brand, tells you most buyers are testing multiple creative variants. The gap between ads and placements, about ten placements per ad, tells you each creative surfaces fairly often once it is approved.
Who is already buying ChatGPT ads?
Look at the names and the pattern is obvious. Mastercard leads with 3,490 placements. Cloudflare, Monday.com, Salesforce, SAP, Carta, RingCentral, and HiBob round out a top 10 dominated by enterprise software, fintech, and developer tools. Capterra and BestMoney are the comparison-shopping aggregators that effectively arbitrage the surface. If your buyer is a developer evaluating infrastructure or a finance leader comparing vendors, you are competing against brands with mature demand-gen budgets who got here early.

The 15 largest advertisers captured 23,617 of the 73,720 placements we measured, about 32% of the entire surface. That is 0.7% of the 2,210 brands we track controlling nearly a third of all the sponsored responses ChatGPT serves. The remaining 2,195 advertisers split the other 68%, which averages out to roughly 23 placements per smaller advertiser. Concentration at this level means a few things for anyone evaluating the channel: the leaders are spending, the long tail is large but thin, and there is real signal in which categories they are concentrated in.
Which categories get the most ChatGPT ad spend?
Enterprise software and fintech lead with 2,562 tracked ads across 895 advertisers, followed by SaaS and productivity tools (786 advertisers) and real estate (617 advertisers). The pattern is consistent: the categories where buyers ask long, specific comparison questions are the ones where sponsored answers fit naturally. Healthcare & HealthTech, Career & Jobs, and Education & Learning sit in the middle tier. Consumer categories like Pet Care, Insurance, and Food & Beverage are still sparse, with 4 to 18 ads each. If your category is on the sparse end, the question is not whether ChatGPT ads work, it is whether your buyers are asking ChatGPT the kinds of questions that would surface them.
How to decide if ChatGPT ads are worth it for you
Three signals matter. First, look up your category in our niche library and check the advertiser count. If fewer than 50 brands are active in your space, the channel is not mature enough for an auction or optimization to drive efficient outcomes; you are buying access, not scale. Second, look at the top advertisers in your niche and ask whether your buyer profile matches theirs. Enterprise and fintech advertisers win because their buyers are mid-funnel and comparison-heavy, which is exactly the moment a ChatGPT recommendation lands. Consumer and local-service categories have not yet produced enough trigger volume to justify significant spend. Third, compare share to total inventory. The Enterprise & Fintech niche alone holds 2,562 of the 7,181 ads we track, so an advertiser in that space faces real competition. A niche with 8 ads, like Insurance, is wide open.
The most useful question: would my buyer ask ChatGPT this question? If yes, and the category has at least 100 active advertisers, ChatGPT ads are worth testing. If no, or the niche has fewer than 20 advertisers, spend the money somewhere else.
