ChatGPT ads data for October 2026: key numbers

Key findings: ChatGPT advertising in October 2026

1. No advertiser dominates overall. The ten most-seen advertisers together hold 10.5% of placements, and 3,123 advertiser websites appeared in only one placement. In our data, ChatGPT ads are a long-tail channel.
2. Comparison and lead-generation sites are a visible group. Thirteen of the top 100, including Consumer Rating, NerdWallet, BestMoney, EverQuote and Forbes's review pages, are comparison, review or quote sites. Together they hold 16.5% of the top 100's placements (5.6% of all placements). This count leaves out home-services marketplaces such as Angi and Thumbtack.
3. One advertiser can lead a category by a wide margin. Expedia had 26.5% of the placements we recorded in travel conversations, Coursera 17.4% in education and careers conversations, and Angi 16.4% in local home services conversations.
4. Many advertisers were new to our data. 8,563 advertisers were first recorded by us in October, and advertiser websites new to our data account for 37.7% of the month's placements.
5. Advertisers write short. The median title is 20 characters, within OpenAI's recommended 16–24 character title range, and the median description is 48 characters, at the top of its 32–48 range.

Top ChatGPT advertisers by industry

The most-seen advertiser excludes ad-tech click links; topic totals include them. "Advertiser websites" counts distinct click domains, so subdomains and second sites count separately (for example, Optimum's two sites). In beauty, Criteo's click links (1,610 placements) appeared more often than the leading brand, and in fashion (1,260) and consumer electronics (1,006) they came close behind the leader. Each such link can stand for many retailers.

What it means for you: in beauty, IT and automotive the most-seen advertiser holds about 3% of placements or less, so no single advertiser stands out. In travel, education and local services, one advertiser holds more than 16% of the topic's placements.

In some topics the second advertiser was close behind: SoFi had 10.2% of personal finance placements after NerdWallet (13.9%), and Fubo 8.5% of media and entertainment after Rocket Money (8.9%). In insurance, BestMoney (8.7%) and GEICO (6.1%) followed EverQuote (12.5%). In local home services, Thumbtack was second with 7.5%, well behind Angi's 16.4%.

New advertisers on ChatGPT in October 2026

8,563 advertisers were first recorded by us in October. The biggest newcomers by placements:

"New to our data" means we had not recorded the advertiser before. Our October collector asked questions in some topics we had not covered before, so part of this number reflects wider coverage, not only advertisers that just started.

How many ChatGPT ads run through Criteo and StackAdapt?

4.0% of placements (14,236) used click links run by ad-tech companies: Criteo (8,249), StackAdapt (3,793) and Google's DoubleClick and Search Ads 360 click servers (2,194). One such link can stand for many different advertisers, so we leave them out of the advertiser rankings. Criteo became the first ad-tech partner for ChatGPT ads in March 2026, and StackAdapt joined as a technology partner in May 2026.

How this ChatGPT ads tracker works (methodology)

• Source: our own collector asks ChatGPT realistic questions in 20 everyday topics from the US and records every sponsored ad shown, with its title, description, advertiser, click link and date. From 1 to 28 Oct it asked 430,856 questions.
• Window: 1 to 28 Oct 2026. Collection was heavier on some days than others and paused on others, so we report the period as a whole, not daily or weekly trends.
• What the numbers mean: a placement is one ad shown in one answer. Counts describe the questions we asked, not all of ChatGPT, and they say nothing about spend, clicks or results. Topic totals mostly reflect how many questions we asked in each topic.
• Advertisers: grouped by brand, with subdomains folded into the main domain (for example, QuickBooks and TurboTax count as Intuit). Ad-tech click links (Criteo, StackAdapt, Google) are counted separately. Advertisers are shown under the brand behind each click domain.
• Tracker: we publish this report every month. Between editions, the ChatGPT ad library and the advertiser directory work as a free, searchable tracker of the ads we capture.

Full method: methodology. For all-time totals, see ChatGPT advertising statistics.
