ChatGPT ads in 2026: what they are, how they work, and how a European business gets in
ChatGPT ads run in 31 European markets since August 2026; self-serve Ads Manager opened on 31 August. What they are, who sees them, how to buy them, what they cost.
Short answer first: ChatGPT ads are clearly labelled sponsored mentions that OpenAI has shown in the US since February 2026 and, since 24 August 2026, across 31 European markets. They appear only to users on the Free and Go plans — Plus, Pro, Business and Enterprise stay ad-free. Since 31 August 2026 a business registered in any of those markets — Slovenia, Croatia and Austria included — can open its own account in the self-serve Ads Manager; larger advertisers can also go through OpenAI's Ads Solutions team and agency partners. For a business, this is the first official way to buy a place inside an AI answer — a space where, until now, the only way in was an organic mention.
I run Flisko, a Slovenian consultancy that helps SMBs in Slovenia, Croatia and Austria with AI adoption and AI-search visibility. This post is the briefing I now give clients who ask "should we be advertising in ChatGPT?" Facts were checked against OpenAI's own pages on 6 September 2026; sources are listed at the end.
What ChatGPT ads actually are
When a user on a free tier asks ChatGPT for a recommendation, a labelled sponsored mention can appear below the answer — not a banner in a sidebar, but a clearly marked suggestion in the conversation flow, separated from the organic part of the reply. Each ad carries the advertiser name and favicon, a title, a short description, a landing page and an image. The timeline has been fast:
| Date | What happened |
|---|---|
| 16 January 2026 | OpenAI officially confirms ad testing — US, logged-in adults on Free and Go plans |
| 9 February 2026 | Ads roll out in the US |
| 5 May 2026 | Self-serve ChatGPT Ads Manager opens to US businesses |
| 18 August 2026 | OpenAI announces the expansion to 31 European markets |
| 24 August 2026 | Ads start serving across all 31 European markets |
| 31 August 2026 | Self-serve Ads Manager opens to businesses in all 31 European markets |
The scale explains the hurry: OpenAI reports over a billion weekly ChatGPT users, and by public estimates more than 80 % of them use the free tier — the tier that sees ads.
Who sees the ads, and who never will
- Sees them: logged-in users on the Free and Go plans, aged 18 or over.
- Never sees them: anyone on Plus, Pro, Business, Enterprise or Edu.
- Also excluded: accounts OpenAI knows or predicts to belong to minors, and conversations on sensitive topics such as health, mental health or politics.
- Opt-out: free users can decline ads in exchange for fewer free messages per day.
The practical consequence: the managing director who pays for Business will never see your ad. The only way to reach that person is an organic mention.
How advertisers buy them
- Self-serve access: since 31 August 2026 a business registered in one of the 31 European markets can open an account at ads.openai.com. The legal entity that advertises and is billed must be based in a listed country; the account is verified (legal name, registration number, company card) before the first campaign, and OpenAI publishes no fixed timeline for that review.
- Managed access: OpenAI's Ads Solutions team, agency partners and technology partners, mainly for larger advertisers.
- Buying models: Reach (CPM), Clicks (CPC) and conversion-optimised campaigns. You set a maximum bid per ad group; OpenAI recommends starting at $3–5 per click, and a relevance-weighted second-price auction decides which ad shows.
- Matching: there are no keywords to buy. You describe the conversations where your offer is relevant with context hints; they guide matching but do not guarantee delivery in a specific conversation.
- Targeting: geo-targeting by country and custom audiences; the creative runs in the language of the conversation.
- Measurement: the OpenAI Pixel, a Conversions API, third-party measurement integrations, and UTM parameters that persist on clicks.
Two honest caveats. There are no European CPM or CPC benchmarks yet — the market opened at the end of August, and any number you read before real campaigns have run is a guess. And the minimum daily budget is not published as a single European figure; advertisers in Slovenia report a floor of 15 € per day in a EUR account, which puts a meaningful two-to-four-week test at roughly 200–400 € of media budget.
Ads or organic AI visibility — a false dilemma
The question every client asks: "Why fix our site for AI crawlers if we can just buy the mention?" The answer is the same one search taught us over twenty years:
- An ad works instantly and disappears with the last impression. Rented space.
- An organic mention builds slowly and stays. Owned space.
- An ad does not change what the model says on its own. If ChatGPT doesn't know you organically, the sponsored slot is all you have — and it vanishes with the budget.
- Ads only reach free-tier users. Everyone on Plus, Pro, Business and Enterprise never sees an ad; an organic mention is the only way to reach them.
The sequence that makes sense for most SMBs: first a solid organic foundation — our free AI visibility test shows in half a minute whether ChatGPT can read your site at all — then ads for the queries and markets where you are not yet mentioned organically.
Getting in as a business in Slovenia, Croatia or Austria
All three countries are on OpenAI's availability list, so you can open the account yourself today, or have us do it in your company's name. If your customers are in Germany or Italy as well, geo-targeting lets one campaign cover them with creative in each language.
We run the whole process for clients — suitability assessment (including an honest "not yet" where ads don't make sense), account opening and verification, query and market strategy, conversation-native creative, and Pixel/Conversions API measurement. What exactly that includes is on our ChatGPT ads service page. Book a free 30-minute call or write to ziga@flisko.si and you'll get a fixed-scope offer within 24 hours.

Frequently asked questions
Are ChatGPT ads live in Europe?
Yes. Ads have been serving to Free and Go users in 31 European markets — all 27 EU member states plus Iceland, Liechtenstein, Norway and Switzerland — since 24 August 2026, and the self-serve Ads Manager opened to businesses in all of them on 31 August 2026.
Can a business in Slovenia, Croatia or Austria open a self-serve ChatGPT Ads account?
Yes. All three countries are listed as available in OpenAI's official Ads Manager availability list. The legal entity that advertises and is billed must be registered in a listed country, and the account goes through verification before the first campaign runs.
How much do ChatGPT ads cost?
You pay per thousand impressions (CPM) or per valid click (CPC), and campaigns can be optimised for conversions. OpenAI recommends a starting maximum bid of $3–5 per click. There are no published European benchmarks for actual click or conversion costs yet, because the first campaigns only started at the end of August 2026.
Do ads change ChatGPT's answers?
No. OpenAI shows ads below the answer, clearly labelled as sponsored, and states that advertising does not influence the answers. Advertisers get aggregate performance data only, never access to conversations, history or memory.
