How Much Do ChatGPT Ads Cost? CPC, CPM and Minimum Spend Explained
The actual pricing mechanics: bidding, the auction, suggested starting bids, and country-by-country minimums.
There's no published rate card for ChatGPT Ads, and anyone quoting you a fixed CPC as a platform-wide standard is guessing. What OpenAI does publish is the mechanics of how pricing actually works, and that's specific enough to plan a budget around.
Three ways to pay
Advertisers choose a campaign objective, and the objective determines both pricing and how delivery is optimized. CPM charges per 1,000 impressions and suits reach and awareness goals. CPC charges per valid click and suits driving traffic. oCPC, conversion-optimized CPC, still charges per click but tunes delivery toward users more likely to complete a specific tracked conversion event.
How the auction actually works
Advertisers set a maximum bid at the ad-group level, a max CPM for Reach campaigns or a max CPC for Clicks campaigns. OpenAI runs a relevance-weighted, second-price auction: the system aims to maximize both advertiser and user value, not simply award the placement to the highest bidder. Ads Manager can also show bid-strength guidance indicating whether a given bid is likely to be competitive.
Daily minimum spend, by country
Campaigns can run on a campaign-total budget or a daily budget. Daily budgets have a country-specific minimum, tied to the ad account's billing currency:
| Country | Daily minimum |
|---|---|
| United States | $25 USD |
| United Kingdom | £15 GBP |
| Canada | $25 CAD |
| Australia | $25 AUD |
| New Zealand | $25 NZD |
| Mexico | 150 MXN |
| Brazil | 40 BRL |
| Japan | 2,500 JPY |
| South Korea | 25,000 KRW |
| India | ₹725 (self-serve from Sept 4, 2026) |
India's minimum was published in OpenAI's campaign documentation before the market even launched, and that preparation paid off: ads went live in India on August 27, 2026, with self-serve access opening September 4 at exactly that ₹725 daily minimum.
What actually changes what you pay
Competitive density in your category, how tightly your context hints and creative match real conversations, and which objective you choose. A broad, vague ad group competing with dozens of advertisers for generic attention will cost more per outcome than a narrow one built around a specific, well-described use case, the same dynamic that shows up in every auction-based ad platform.
Budgeting for a first campaign
The daily minimum is a floor, not a working budget. A brand testing ChatGPT Ads for the first time needs enough spend to actually see a pattern, not just clear the minimum threshold. A useful rule of thumb borrowed from other auction platforms: budget for at least 15-20 conversions worth of spend before judging a context hint, ad group or creative variant as a win or a loss. Below that volume, the difference between a good result and a bad one is mostly noise, not signal.
Want a real budget plan, not a guess?
We'll build one against your category and market, not a generic benchmark.
Before setting any budget, confirm your market actually has self-serve access; see the current availability breakdown. And run through the readiness checklist before your first campaign goes live. For everything in one dated reference, see the Nivaro field guide.
