OpenAI switched ads on inside ChatGPT (OpenAI Ads) across 31 European markets on August 24, 2026. That covers the whole European Economic Area plus Switzerland. The rules differ from Google Ads more than they look at first glance.
I have been running ads inside ChatGPT since April 2026 on a US account. Roughly $33k went through it in four months. The ratios, the tables and the five things that decide how a new account performs are in a separate article on managing ChatGPT Ads.
What OpenAI switched on
Ads had run inside ChatGPT since February 2026, in nine markets: the US, Canada, Australia, New Zealand, the UK, Japan, South Korea, Mexico and Brazil. The European expansion was by far the biggest step.
| Item | Detail |
|---|---|
| EEA and Switzerland launch | August 24, 2026, 31 markets at once |
| Who sees ads | Free and Go plans; paid Plus, Pro and Enterprise do not |
| Advertiser access | Managed early access from Aug 24, EUR 80,000 minimum for month one |
| Self-serve | From August 31, 2026, open to everyone |
| Targeting | Geo, custom audiences, contextual signals from the conversation |
| Measurement | OpenAI Pixel, Conversions API, third-party integration |
| Optimization | Now conversions too, not only clicks |
Paid plans account for roughly 35 million of 900 million users. The remaining 865 million will see ads.
The launch has two speeds and the second one matters
A sales-managed early-access program opened on August 24. It was available to advertisers based in EU countries, the Czech Republic included. OpenAI sales ran the onboarding and the advertiser had to commit EUR 80,000 for the first month. You could split that budget across several campaigns and markets, but the minimum applied to the whole ad account.
On top of that: signed advertising terms and an order form, a legal entity, billing and invoicing, and account access. Then came the reviews of advertiser category, target market, creative and landing page, plus whatever measurement or product feed the campaigns needed.
Self-serve account creation opened on August 31, 2026. That is when both the minimum budget and the salesperson on the other side went away.
Consent works differently here, and it will show
This is the biggest departure from Meta and Google. In Europe, OpenAI builds personalized advertising on explicit consent, not legitimate interest. Users can withdraw it at any time.
Decline it and you still see ads. Contextual ones, assembled from the live conversation and a rough location, with no chat history involved. Advertisers never reach the content of conversations.
Two consequences follow:
- Personalized audiences will start small. You already know your own consent rate from your cookie banner. Expect a similar order of magnitude, not US numbers.
- Contextual targeting will be the main channel, not a fallback. Whoever works with the context their product gets mentioned in has the advantage. It is the same discipline as optimizing for AI Overviews.
Three things that surprised me on the US account
- Bidding type cannot be changed later. You pick it when you create the campaign and it stays that way, not even through the API. That account went through two full rebuilds because of it. Moving from clicks to conversions then cut CPC by 69 % and lifted CTR by 61 % on identical text ads.
- The auction floor is invisible. Thirty correctly configured campaigns delivered a single impression across a whole day, because they bid a target CPA of $2.50. Raising it to $20 produced 523 times the delivery the same day. The platform never flags it.
- Keywords do not win everything. Keyword ad groups had the highest CTR, but prompt context, a plain-language description of the person and their situation, bought clicks 16 % cheaper. One keyword per ad group lost on both counts.
The full breakdown with tables is in what managing ChatGPT Ads actually taught me.
Four steps before you start
You do not need to move budget anywhere. Preparing pays off:
- Sort out measurement. Without the pixel and the Conversions API you cannot evaluate the channel. Deploy them before you spend anything. Of five Google Ads accounts I took over, three were optimizing toward a number that did not mean revenue.
- Write down which conversations your product belongs in. Contextual targeting works with topics, not keywords. You want buying situations, not phrases.
- Track incrementality, not just last-click attribution. What matters is how many orders would not have arrived without ChatGPT Ads. Last click will have you switching the channel off after three weeks even when it was profitable.
- Do not cut your existing search budget for this. ChatGPT Ads is an addition, not a replacement. Move half your budget into a new channel now and you lose revenue.
Where this is heading
Ads inside ChatGPT are not another display network. This is the first large ad system built on a conversation rather than a query. Shopping is moving the same way, which I covered in the article on agentic commerce.
Summary
- ChatGPT Ads has been live across the EEA and Switzerland since August 24, 2026. Every EEA market was in the first wave.
- Free and Go plans see ads, which is roughly 865 million of 900 million users.
- Personalization runs on explicit consent. Contextual targeting will therefore be the main channel, not a fallback.
- The managed August 24 start carried an EUR 80,000 minimum for month one. Self-serve opened on August 31 and for most stores that was the real beginning.
- Deploy the OpenAI Pixel and Conversions API before you spend anything. Your Google Ads GTM container will not cover it.
- What actually decides performance is in the practical breakdown of managing ChatGPT Ads.
Learn now how attention gets bought in this environment and you have a year's head start. Wait until it becomes standard and you pay prices somebody else set.
I build the account on conversion bidding from day one, so you do not start with a rebuild. What ChatGPT Ads management covers is on its own page.
