How Much Do ChatGPT Ads Cost in 2026?
ChatGPT Ads are priced on a cost-per-thousand-impressions (CPM) model for the Reach objective and a cost-per-click (CPC) model for the Clicks objective. There is no platform minimum spend. That is the short answer. What follows is everything you need to know to budget sensibly — including the caveats every advertiser should understand before committing money.
How are ChatGPT Ads priced?
The ads.openai.com platform offers two campaign objectives, each with its own pricing model:
- Reach (CPM): You pay per thousand impressions. This is the default objective and the one confirmed in the public API. It is the right choice when your goal is awareness or reaching a large share of ChatGPT's free-tier audience.
- Clicks (CPC): You pay per click. CPC bidding went live in the Ads Manager UI on May 5, 2026. It is designed for advertisers whose primary goal is driving traffic to a landing page.
You set a maximum bid — the most you are willing to pay per thousand impressions or per click — and the platform runs an auction. The API accepts bids in micros (millionths of a currency unit), but you can set this through the Ads Manager interface without touching the API.
Important note on the Clicks objective: CPC bidding is live in the UI but is not yet reflected in the public API documentation. If you are building programmatic campaigns, verify the current API reference at developers.openai.com/ads before relying on CPC billing via the API.
What is a typical CPM or CPC?
Observed early ranges
| Metric | Working range | Notes | |---|---|---| | CPM (Reach) | ~$25–$45 | Launched at $60 in Feb 2026; eroded to ~$25 by mid-April. Some managed deals via Criteo reported as low as $15 — not typical for self-serve. | | CPC (Clicks) | ~$3–$8 | Practitioner-recommended starting max bid: $3–$5. Realized range $2.50–$8 by category. CPC launched May 5, 2026 — almost no historical depth. |
These are early, thin, US-centric figures — not guaranteed performance. Results will vary.
To illustrate the range using the CPM midpoint of $35:
- At $25 CPM (lower end): $100/day buys roughly 4,000 impressions.
- At $35 CPM (midpoint): $100/day buys roughly 2,900 impressions.
- At $45 CPM (upper end): $100/day buys roughly 2,200 impressions.
For CPC at a $5 midpoint, $100/day buys roughly 20 clicks — at $3 CPC you might get ~33, at $8 you might get ~12. Show clients the range, not a single number. You will not know where your account lands until you have two to four weeks of real data.
Is there a minimum budget?
No minimum spend applies as of May 2026. The original managed-pilot required $200,000–$250,000 in commitments. OpenAI removed the barrier when it opened self-serve access to all US businesses on May 5, 2026. The API sets a technical floor of $1 lifetime budget, which is not a meaningful constraint for any real campaign.
This is a significant change. It means smaller advertisers, agencies, and brands that cannot commit to five-figure monthly spends can now test the platform directly.
One important caveat: your budget may not fully deliver. An early enterprise advertiser spent only 3% of a $250,000 budget over several weeks because inventory was limited. Under-delivery is a genuine risk, particularly at launch and in less competitive categories. Do not build performance forecasts that assume 100% budget utilization.
What should I budget to start?
There is no single right answer, but here is a practical framework for expectation-setting.
Illustrative starting budgets
The table below uses the mid-range CPM ($35) and CPC ($5) figures from the observed ranges above. This is arithmetic, not a forecast.
| Monthly budget | Objective | Estimated impressions | Estimated clicks | |---|---|---|---| | $1,500/mo (~$50/day) | Reach (CPM) | ~43,000 | — | | $1,500/mo (~$50/day) | Clicks (CPC) | — | ~300 | | $3,000/mo (~$100/day) | Reach (CPM) | ~86,000 | — | | $3,000/mo (~$100/day) | Clicks (CPC) | — | ~600 | | $15,000/mo (~$500/day) | Reach (CPM) | ~429,000 | — | | $15,000/mo (~$500/day) | Clicks (CPC) | — | ~3,000 |
Ranges: at $25 CPM the impression counts are ~40% higher; at $45 CPM they are ~22% lower. At $3 CPC click counts are ~67% higher; at $8 CPC they are ~37% lower.
Retainer vs. ad spend: two separate line items
Your advertising budget has two distinct components:
- Media spend — the money paid directly to ads.openai.com for impressions or clicks. This goes to OpenAI.
- Management fee — what you pay an agency or consultant to handle strategy, account setup, creative production, bid management, and optimization. This is separate from your media spend.
A $3,000/month budget does not mean $3,000 going to OpenAI. If you are working with an agency, discuss how the retainer is structured before you set spend expectations.
How long to test before drawing conclusions
Given the platform's limited inventory and volatility, plan for a minimum of four to six weeks before evaluating performance. The first two weeks are often spent getting creative approved, bids calibrated, and delivery stabilized. Pull your actual CPM, CPC, CTR, and conversion data from the Ads Manager Insights section after that window and replace the estimates above with your account-specific benchmarks.
