On 24 August 2026, OpenAI switched on advertising inside ChatGPT across 31 European markets, Ireland included. A week later it began opening its self-serve Ads Manager to European advertisers. So for the first time, an Irish business can buy ad placement inside the thing a lot of their customers now use instead of Google.
Here is what actually shipped, what the ads look like, who sees them, and my honest read on whether it is worth your money yet.
Moving quickly. This launched days ago and OpenAI is still rolling features out market by market. Everything below reflects the position at the start of September 2026 — check your own Ads Manager before planning spend.
What happened, and when
The rollout ran in two steps, and the second one is the part that matters for small businesses.
- 24 August 2026 — ads began appearing for ChatGPT users across 31 European markets, taking OpenAI to roughly 40 markets globally. Buying was restricted to OpenAI's own ad sales team and the big agency holding groups.
- End of August 2026 — self-serve access to Ads Manager started opening to European advertisers, described by OpenAI as covering everyone from startups and SMBs up to global brands. Reporting around the launch put the ads business at roughly a $1 billion annual run rate.
The practical translation: a week ago you needed an agency with a holding-group relationship. Now you are meant to be able to log in and build a campaign yourself.
Who actually sees these ads
This is the number that should shape your expectations, and it gets glossed over in most of the coverage.
Ads only appear for people on the Free and Go plans. Anyone paying for Plus, Pro or Enterprise sees no ads at all.
That cuts both ways. The free tier is where the bulk of ChatGPT usage sits, so the reach is real. But the paying, higher-intent, often more commercially valuable users are exactly the ones you cannot reach this way. If your customers are the sort of people who expense a Plus subscription, your addressable audience here is smaller than the headline user numbers suggest.
What the ads look like
They sit below the assistant's answer as a clearly labelled unit, not inside the answer itself. OpenAI has been explicit that advertising does not influence the responses ChatGPT gives — the ad is adjacent to the answer, not baked into it.
In practice the format is closer to a native placement than a display banner: brand name, headline, short description, an image, and a link out. It is designed to sit beside a conversation rather than interrupt it.
How targeting works
This is the genuinely new part, and it is worth understanding before you write your first ad.
Placement is driven by the conversation. OpenAI has described matching on the topic of the current chat, the user's past chats and saved memory, and their previous interactions with ads — rather than third-party cross-web tracking of the kind that has been dying off for years.
The consequence: you are not really buying keywords, you are buying moments in a conversation. Someone describing a problem in their own words is a different target than someone typing three words into a search box. Ad copy written for Google Ads will mostly not fit.
Users can control ad personalisation in their settings. Worth knowing: opting out changes which ads someone sees, not whether they see ads at all.
How to buy ChatGPT ads from Ireland
Two routes, depending on where the rollout has reached your account.
- Self-serve Ads Manager. The intended route for most businesses. Access opened to European advertisers at the end of August and OpenAI indicated full European Economic Area availability in early September. Advertisers need to be in approved categories and clear policy checks.
- Through OpenAI's ad sales team or an agency partner. The original route, and still how larger budgets are placed. Realistically aimed at spend levels well above a typical Irish SME.
If self-serve has not reached your account yet, the honest answer is to wait rather than chase an agency workaround for a few hundred euro a month.
Should an Irish small business actually bother yet?
I would rather tell you this straight than sell you a new channel.
Probably worth a small test if: you sell to consumers, your product is discovered through open-ended questions rather than precise searches, you already have Google Ads working and a landing page that converts, and you can afford a few hundred euro on a genuine experiment with no promise of return.
Probably not yet if: your Google Ads and local SEO are not sorted, you are B2B selling to people who almost certainly pay for Plus, your budget is tight enough that this money would come out of something already working, or you would need to build new landing pages to run it properly.
The benchmarks do not exist yet. Nobody in Ireland has a year of ChatGPT ads data to tell you what a normal cost per acquisition looks like. Anyone quoting you confident performance numbers in September 2026 is guessing, and you should treat that as information about them.
For most of the businesses I work with — trades, clinics, solicitors, restaurants — Google Ads and local SEO will still return more per euro this quarter. That is not a reason to ignore ChatGPT ads. It is a reason to size the test honestly.
What I would do this month
- Log into Ads Manager and check whether your account has self-serve access yet. Costs nothing.
- Look at how your business is currently described when someone asks ChatGPT about your category. That is your baseline whether you advertise or not.
- If you test, cap it. Set a number you are willing to lose, run it for a full month, and judge it on enquiries rather than impressions.
- Write the copy for the format. Answer the question a person is actually asking mid-conversation, rather than recycling a Google Ads headline.
- Fix the destination first. A new ad channel pointed at a slow, vague page will fail the same way the last one did.
The bit worth remembering. A new channel is not an advantage on its own. It is an advantage if your site converts and your tracking works, and a fast way to lose money if they do not.
Common questions
Are ChatGPT ads live in Ireland?
Yes. Ireland was part of the 31-market European rollout that went live on 24 August 2026.
Can a small Irish business buy them directly?
That is the intention. Self-serve Ads Manager began opening to European advertisers at the end of August 2026, with wider European Economic Area availability indicated for early September. Check your own account, as access is being granted in stages.
Will everyone see my ad?
No. Only users on the Free and Go plans. Plus, Pro and Enterprise subscribers see no advertising.
Do ads change the answers ChatGPT gives?
OpenAI states they do not. Ads are labelled and kept separate from the assistant's response.
What does it cost?
There is no reliable Irish benchmark yet. Treat any confident figure quoted this early with suspicion, including mine — which is why I am not quoting one.
Is this the same as showing up in ChatGPT answers organically?
No, and the difference matters. Ads are paid placement beside the answer. Being referenced inside the answer is an earned outcome that comes from the same fundamentals as search visibility. Both are worth attention; only one has an invoice.
Where this goes next
Ad products get more sophisticated and more expensive as they mature. Early auctions are usually cheaper simply because fewer advertisers have shown up. That is the honest case for testing now — not because anyone can prove the return yet, but because the cost of finding out is temporarily low.
The businesses that will do well out of this are the ones whose fundamentals already work. If you want a straight answer on whether that is you, get in touch and I will tell you.
I've spent the last four years working with owner-led businesses in Cork and across Ireland — first in-house at a fast-growing Irish ecommerce brand, then agency-side running teams, and now independently. I write about what I actually see in client accounts, not what's fashionable this quarter.
