|---|---|---|
| Views | Per 1,000 impressions (CPM) | Being seen |

What a click and a thousand views cost
OpenAI suggests a starting bid of $3 to $5 per click. It runs a second-price auction weighted by relevance, so a very relevant ad can win for less than its bid. Third-party reports from June 2026 put CPM at about $25 to $60.
A worked example
A $25 daily budget at a $4 average click buys about 6 clicks a day, or about 190 a month for about $750. At the 0.68% average click rate Similarweb reported, those clicks come from roughly 28,000 ad views a month.
How the budget behaves
- Your daily budget is an average. One day can spend up to twice the daily amount.
- Over a Sunday to Saturday week, spend stays under seven times the daily budget.
- Spend numbers can lag 7 to 8 hours in reports. A $0 spend line does not mean nothing was charged.
Common questions
Is there a minimum spend for ChatGPT ads?
Yes. OpenAI sets a minimum daily budget by billing currency, for example $25, €15 or £15 a day. Many blog posts still say there is no minimum. That is out of date.
How much does a click on a ChatGPT ad cost?
OpenAI suggests starting with a maximum bid of $3 to $5 per click. Third-party reports from mid-2026 put real costs in the same range, with some advertisers paying less.
What is the CPM for ChatGPT ads?
Reported CPMs run about $25 to $60 per 1,000 impressions as of June 2026.
Do I pay per conversion?
No. Even when you optimize for conversions, you are billed per click (oCPC) or per 1,000 impressions (oCPM).
Can my daily spend go over my budget?
Yes, up to twice the daily budget on a single day. Over a seven-day week, spend will not go past seven times the daily budget.
