Today, ChatGPT ads landed in 31 more European countries, including Germany, France, Spain, Italy and the Netherlands. It is OpenAI’s biggest advertising rollout since it began testing ads in the US back in February. For UK businesses, today marks the end of something quieter: an eleven-week head start most never knew they had.

We have been watching this rollout closely because we build AI systems for small UK businesses, and ad platforms with a limited pool of advertisers are exactly the moment worth testing early. That window has now closed. Here is what changed today, what the UK’s early access was actually worth, and what we would do about it this week.

What changed today

OpenAI confirmed that ChatGPT Ads are now live across 31 additional European markets, among them Germany, France, Spain, Italy, Sweden, Norway, Denmark, Poland and Portugal. The company has called it its largest ads expansion to date, and coverage of the rollout confirms advertisers in these new markets are starting through OpenAI’s Ads Solutions team and agency partners, with self-serve access through Ads Manager following later this year.

Ads appear as small, clearly labelled “Sponsored” links beneath ChatGPT’s own answers, matched to the conversation a user is having. They only show to people on the Free and Go plans; anyone paying for Plus, Pro, Business or Enterprise sees nothing, and OpenAI says it does not serve ads to accounts it identifies as belonging to under-18s.

The UK’s quiet eleven-week head start

The UK became the first European market to get ChatGPT ads on 6 June 2026, with self-serve Ads Manager access from day one, months ahead of the rest of the continent. That is roughly eleven weeks in which UK advertisers were bidding into a comparatively small pool of competitors, before the auction opened up to businesses across 31 more countries today.

Most UK small businesses never touched it. We would guess the vast majority did not know ChatGPT ads existed in the UK at all, let alone that there was a quieter, cheaper on-ramp before the rest of Europe piled in. That gap will not stay open. As more advertisers compete for the same ad slots, we expect bidding to get more expensive, the same pattern every ad platform has followed since AdWords launched.

How the ads actually work

ChatGPT Ads run on an auction, not a fixed rate card. OpenAI uses what it calls a relevance-weighted, second-price auction to decide which sponsored link appears beneath an answer, similar in principle to how Google Ads has worked for two decades. Buying is available on a cost-per-click or cost-per-thousand-impressions basis through Ads Manager.

OpenAI’s own guidance to advertisers recommends starting cost-per-click bids somewhere between $3 and $5, though that is US dollar guidance rather than a guaranteed UK price, and independent UK performance data is still thin this early. On the impressions side, reporting on OpenAI’s ad pricing puts the default maximum bid for CPM campaigns at $60 at launch, though real-world rates have reportedly settled lower, down to around $25, as the auction has matured.

Crucially, OpenAI says advertising does not influence ChatGPT’s actual answers. Ads run on a separate system, and the company’s help centre states that advertisers cannot shape, rank or alter the response itself, only the sponsored link that sits underneath it. That separation matters for trust in the product, but it also means an ad here cannot do what a well-optimised website can, namely shape how your business gets described in the answer itself. The ad is a bolt-on, not a rewrite of the conversation.

Worth noting too: ChatGPT now has roughly one billion weekly active users, and OpenAI says around one in five of those conversations shows commercial intent, someone comparing products, asking for recommendations, or working out what to buy. That is the pool of attention this auction sits underneath, and it is a large part of why OpenAI describes its ad revenue as having grown by more than a quarter since the start of this month alone.

Is this worth your time

Before you open an Ads Manager account, be honest about whether this fits how your customers actually search. ChatGPT ads tend to make more sense for businesses with:

• A clear, single action you want someone to take (book a call, request a quote, buy a product), because the ad is one small link under an answer, not a full-funnel placement.
• Products or services people genuinely ask AI chatbots about, rather than search for by brand name.
• Enough margin per sale to absorb a testing budget while UK-specific pricing data is still scarce.

If you run a purely local trade, most of your leads still come from word of mouth, Google Business Profile or Checkatrade-style directories, and ChatGPT ads are probably not your first move. If you sell online, or you are already running Google or Meta ads and have some budget spare to test, it is worth a small, time-boxed trial while data from this newly competitive market is still forming.

What we would do this week

We are not going to promise you results, and we are not going to tell you what to spend, only what tool costs look like. What we would actually do, in order:

• Set up an Ads Manager account and run one small, tightly scoped campaign, no more than you would spend testing any new channel, with a single clear call to action.
• Track cost per click and cost per resulting enquiry against your existing channels for at least two to three weeks before drawing any conclusions from such a young dataset.
• Check your ad copy and landing page comply with UK advertising and data protection rules exactly as you would for any other paid channel. A new platform does not mean lighter compliance.

The head start is gone. What is left is a genuinely new, still-thin-on-data channel that thirty more countries just started competing for. Testing early, carefully and with a small budget still beats waiting for the case studies to catch up.
