How many people can a ChatGPT ad actually reach?
Describe your audience in your own words. Get its size, what a click should cost, and the budget a real test needs.
[ The estimate ]
The same kind of description you would give ChatGPT Ads: the conversations, topics or moments where what you sell is relevant.
[ How the numbers are built ]
We read your hint like the ad platform
Your description becomes the searches that same buyer would type.
We price those searches live
Real monthly volume and cost per click, pulled fresh.
We divide to get people, never multiply
One buyer searches a decision several times, so people are always fewer.
We adjust the click price in tiers
Below roughly three dollars, ChatGPT costs more than Google. We say so.
We cross-check from inside ChatGPT
A second estimate from OpenAI's own figures, every coefficient sourced.
We say when the data is thin
A weak signal gets labelled, not dressed up as a measurement.
The full picture of what ChatGPT ads cost, from the accounts we run, is in our ChatGPT Ads cost guide.
[ FAQ ]
Where does the audience number come from?+
Live keyword volume for the searches your description implies, divided by how often one buyer repeats that search. Both numbers are shown in the result.
Why Google data for a ChatGPT tool?+
No public index of ChatGPT conversations exists. Google sizes the topic; ChatGPT's own figures size how much of it is reachable.
How accurate is the cost per click?+
It is a planning range, anchored on the accounts we run. The auction is young and has already repriced once. OpenAI's own June to July 2026 sample counted more than 10,000 advertisers above $100 spend and 100 clicks in a single month, so there is real competition setting these prices.
How many estimates can I run?+
One, then three more from the report we email you.
Is this financial advice?+
No. It sizes an opportunity. What a campaign returns depends on your offer and your creative.
Worth testing?
Then the next question is who builds the campaign.
