Field note: Test cost field note
Talk to us Talk to usA ChatGPT ads test costs a minimum of 25 USD per day per campaign in the United States, with local equivalents elsewhere. That floor is the price of entry, not the price of an answer. A readable test is one that buys enough clicks to distinguish a real result from noise, which is usually a multiple of the floor.

Common questions
What is the minimum spend for ChatGPT ads?
The documented minimum is 25 USD per day per campaign in the United States, with local equivalents such as 15 GBP, 2,500 JPY, 25,000 KRW, and 150 MXN. This is a per-campaign floor, so running several campaigns multiplies it.
Is there still a 200,000 USD commitment to advertise on ChatGPT?
No. The 200,000 USD entry commitment was removed on 5 May 2026. The per-campaign daily floor of 25 USD in the United States remains in place.
What CPC should I bid on ChatGPT ads?
OpenAI recommends starting between 3 and 5 USD for CPC campaigns. For product feed campaigns, reported guidance is around 3 USD, and bids below 2 USD are reported to receive minimal traffic.
How long should a ChatGPT ads test run?
Long enough to buy a conversion count you would act on. At the 25 USD floor and a 4 USD CPC, a single campaign buys roughly six clicks a day, so short tests at the floor produce spend rather than signal.
