How Often Does ChatGPT Show Ads?
Klaas FoppenChatGPT ad frequency over time
How often ChatGPT Search served an ad between May 20 and August 17, 2026. Each bar is one day and totals 100%: the dark segment is responses with at least one ad, the light segment is responses without. The count only includes responses where ChatGPT searched the web, returned at least one citation, and completed ad extraction.

What this means for you
The 90-day average was 20.1%, but the average hides the story. ChatGPT served no ads at all until May 27, when they appeared in 1.69% of responses.
From there the rate climbed in bursts: a brief spike on June 25 and 26, then a jump past 30% on July 1 that stuck. Since then the daily rate has mostly sat between the low 20s and high 30s, and the past seven days averaged 32.4%.
How to act on it
- Check ad visibility across several days before drawing conclusions. A single prompt run can land on one of the outlier days in this chart.
- Track which advertisers and landing pages show up on the prompts you care about. The rate tells you how often an ad slot appears; the ad details tell you who wins it.
Share of ChatGPT ads by type
Of the responses that contained ads, which prompt types did they come from? Each bar totals 100% across organic, brand-specific, and competitor-comparison prompts, and days without any ads are left out. Keep in mind this is a volume mix: it shows where the ads appeared, not how likely each prompt type is to trigger one.

What this means for you
Organic prompts account for most of the ads: 73.1% of ad-bearing responses on an average day. Brand-specific prompts contributed 17.9% and competitor comparisons 9.1%.
The mix moved around most in the early weeks, with organic swinging between 62.71% and 78.32% and competitor comparisons between 7.24% and 15.60%. Since July 1 the split has been much steadier.
How to act on it
- Remember that this mix reflects prompt volume. Adding more organic prompts to a monitor raises their share here even if nothing changed on OpenAI's side.
- Compare advertisers per segment. Brand-specific and competitor-comparison prompts are a smaller slice, but the ads that appear there can differ from what organic prompts attract.
