What are ChatGPT ads?
ChatGPT ads are sponsored messages that OpenAI shows inside ChatGPT, placed beneath the AI-generated answer and matched to the context of the conversation. They are clearly labeled, served through a separate ad layer, and OpenAI has been explicit that ads do not influence the answer ChatGPT gives.
For most of ChatGPT's first two years, advertising was not part of the plan. OpenAI bet on subscriptions, API revenue, and enterprise contracts. That changed in February 2026, when ads arrived for a small group of enterprise brands. Since then the model has been rebuilt into a self-serve auction that performance teams can buy into — the same direction Google and Meta travelled years earlier, compressed into months. For the full pricing story, see our explainer on what ChatGPT ads cost.
What a ChatGPT ad looks like
An ad appears as a single labeled sponsored unit below a ChatGPT response, visually separated from the answer. Targeting does not use keywords or demographics. Instead, advertisers write plain-language “context hints” that describe the conversations, topics, or scenarios where their product should surface, and OpenAI's ad ranking decides when to show it.
OpenAI is also testing multi-advertiser units that group several advertisers inside one sponsored placement. The format expands the inventory buyers can compete for without increasing how many ads a user sees — the most relevant ad is shown first, and each slot is still decided by the same auction.
How ChatGPT ads are priced
There is no fixed rate card. ChatGPT ads run through an auction, so two advertisers targeting similar audiences can pay different amounts depending on competition and how relevant their ad is. Within that auction, OpenAI currently confirms two pricing models, with a third in testing.
CPM — paying for impressions
CPM (cost per thousand impressions) was the only model at launch. OpenAI lists a default maximum bid of $60 per 1,000 impressions in its Help Center documentation. In practice:
- 10,000 impressions at $60 CPM = $600
- 100,000 impressions at $60 CPM = $6,000
- 500,000 impressions at $60 CPM = $30,000
CPM is built for reach and brand exposure. At launch it also carried a $200,000 minimum commitment, which limited the early pilot to large brands.
CPC — paying for clicks
In April 2026, OpenAI activated cost-per-click buying. Advertisers pay only when a user clicks, and OpenAI recommends a starting max bid of $3–$5 per click. At those rates:
- 1,000 clicks at $3 CPC = $3,000 / at $5 CPC = $5,000
- 5,000 clicks at $3 CPC = $15,000 / at $5 CPC = $25,000
- 10,000 clicks at $3 CPC = $30,000 / at $5 CPC = $50,000
The $3–$5 range puts ChatGPT broadly in line with Google Search for general categories. The minimum spend fell alongside CPC — first to $50,000, then removed entirely when the self-serve Ads Manager opened to all U.S. advertisers in May.
CPA — paying for outcomes (in testing)
A third model, cost per action, is in pilot testing with selected advertisers. Under CPA the advertiser pays only when a user completes a defined action — a click-through, sign-up, or purchase — and the platform absorbs the cost of serves that do not convert. Access depends on having conversion tracking live through the OpenAI pixel or Conversions API. OpenAI has not confirmed CPA pricing publicly, and it is not yet in the official documentation.
How the ChatGPT ads auction works
Both CPM and CPC campaigns run through the same engine: a relevance-weighted, second-price auction.
Second-price means the winner pays just above the next-highest bid, not their full ceiling. Set a $5 max CPC and beat a competitor bidding $3.20, and you pay $3.21.
Relevance-weighted means the bid is not the only factor. The auction weighs:
- Context hints — the plain-language descriptions of where your ad should appear
- Ad copy and title — how well the message matches the conversation
- Landing page relevance — whether the destination fits what the user asked
- Competition — how many advertisers are targeting the same context
The practical takeaway: a lower bid with stronger relevance can beat a higher bid with a poor match. Precise context hints and ads built for specific use cases matter as much as the number you bid.
How to launch a ChatGPT ads campaign
The self-serve Ads Manager uses a Campaigns → Ad Groups → Ads structure that anyone who has used Google Ads or Meta will recognise. A typical path to a first campaign:
- Get access. Self-serve is open to U.S. advertisers; in newer markets you register interest with OpenAI directly.
- Choose a pricing model that matches your goal — CPM for reach, CPC for traffic you can measure.
- Write strong context hints in plain language, describing the conversations where your product genuinely helps. Vague hints produce weak relevance scores.
- Set your bid within OpenAI's guidance ($60 default max CPM, $3–$5 CPC).
- Install conversion tracking via the OpenAI pixel or Conversions API so you can measure outcomes — and qualify for CPA if it opens up.
Where ChatGPT ads are available
The rollout has been deliberately staged. Ads started in the U.S. in February 2026, expanded to Australia, New Zealand, and Canada in March, and went live in the UK — OpenAI's first European market — soon after. OpenAI has named Japan, South Korea, Brazil, and Mexico as the next markets. A market being live for users is not the same as self-serve buying being open: UK advertisers, for example, currently run pilots through OpenAI reps while self-serve remains U.S.-only.
Who sees ChatGPT ads
Ads reach only users on ChatGPT's Free and Go tiers. Plus, Pro, Business, Enterprise, and Education users see no ads. Ads also stay away from health, mental-health, and political content. These constraints matter for planning: the most engaged, highest-spending users skew toward paid, ad-free plans, which shapes the addressable audience.
How ChatGPT ads compare to Google and Meta
OpenAI's $3–$5 CPC sits in the same bracket as Google Search for general categories, while the $60 default CPM runs well above Meta's typical range. Whether that premium is worth it depends on a question the data has not fully answered: does the intent in a ChatGPT conversation — where a user is actively working through a decision — convert better than a feed or a search result? Early click-through data (around 0.91%, against 6.4% on Google Search) suggests caution, but conversion tracking has only been in place since May, so the performance comparison is still being written.
Common questions about ChatGPT ads
How much do ChatGPT ads cost?
OpenAI confirms two pricing models. CPM campaigns carry a default max bid of $60 per 1,000 impressions. CPC campaigns have a recommended starting bid of $3–$5 per click. What you actually pay is set by the auction, not the ceiling you choose.
What is the difference between CPM and CPC on ChatGPT?
CPM charges for every 1,000 impressions, regardless of clicks, and suits brand awareness. CPC charges only when a user clicks, and suits performance buyers who want spend tied to engagement.
Does ChatGPT use keywords to target ads?
No. Instead of keywords or demographics, advertisers write “context hints” — plain-language descriptions of the conversations where their ad should appear — and OpenAI's ad ranking decides when to show it.
Do ChatGPT ads affect the answers?
OpenAI says no. Ads are served through a separate ad layer and shown as a labeled sponsored unit below the response; they do not influence the model's answer.
Can I pay only when someone converts?
That is the CPA model, currently in pilot testing with selected advertisers who have conversion tracking live. It is not yet generally available, and OpenAI has not confirmed CPA pricing.
Can I run ChatGPT ads outside the U.S.?
Consumer availability is expanding (UK, Australia, New Zealand, Canada, with more markets named), but self-serve buying is currently U.S.-only. Elsewhere you register interest with OpenAI to join the pilot.
What is still unknown
ChatGPT ads have moved fast, and a few things remain genuinely unresolved: CPA pricing has not been confirmed; there are no stable, industry-wide benchmarks yet for conversion rates or return on spend; and the auction is only months old, so clearing prices and competition will keep shifting as more advertisers enter. Advertisers can run campaigns today, but they are in a calibration phase rather than an optimization one.
The bottom line
ChatGPT ads have gone from a $200,000, CPM-only, invite-only pilot to a self-serve, multi-model auction with no minimum spend in a matter of months. The access question is answered, and the pricing benchmarks are clear enough to plan a test. What is not yet answered is whether ChatGPT's intent signal converts well enough to earn a permanent line in the media plan. For marketers, that makes it a channel worth testing now and measuring closely. We keep this guide updated as OpenAI's ad system evolves — see the latest news below.
