ChatGPT starts selling ads in Europe next week, but hotels can't buy them directly yet

Driving the news. On August 18 OpenAI said ChatGPT Ads will start running across Europe next week. Germany, France, Spain, Italy, Sweden, Norway, Denmark, the Netherlands and Austria are named, along with 22 further European countries. The test began in the United States in February, reached Canada, Australia and New Zealand in March, and went live in the UK, Mexico, Brazil, Japan and South Korea on August 11.

A hotelier in Munich or Amsterdam cannot open an account and start bidding. In OpenAI's words: "Advertisers will initially be able to access ChatGPT Ads through the OpenAI Ads Solutions team, agency partners, and technology partners. Self-service access through Ads Manager will follow later this summer."

What that door looks like once it opens. The American version is the preview. OpenAI opened a self-serve Ads Manager there on May 5, added cost-per-click bidding, and said advertisers "are only charged based on a click outcome" — a platform built for "companies of all sizes, from SMBs and startups to global brands."

Cogwheel Marketing, a hotel marketing agency, published results from its own American campaigns on August 11: click-through between 1.6% and 1.9%, at $3 to $3.50 a click, with a working floor around $25 a day. Those are one agency's campaigns in one market, and no European cost data exists yet.

The ad itself is small. One square image, a headline capped at 50 characters that truncates on screen after 24, and 100 characters of description that truncate after 48.

Who will actually see it. OpenAI: ads "will be shown only to users on the Free and Go plans." No ads run on Plus, Pro, Business, Enterprise or Education. And free users can switch ads off altogether in exchange for fewer messages a day.

So the reachable audience is the free tier minus everyone who opted out, plus Go. Read that against your rate card. The guest paying for a better assistant every month, and the corporate traveler whose employer bought a Business plan, are the two people most likely to take the suite and the two guaranteed never to see you.

The catch. No European operator has cost data to work from. The only hotel figures anywhere come from one agency's American campaigns, in a market six months ahead of this one. OpenAI's stated timing for European self-serve is "later this summer" and nothing firmer than that. And whatever it turns out to cost, the ceiling on who can see it is already fixed.

What it means for hotels. The ad does not sit in the recommendation. OpenAI's documentation says ads "appear below ChatGPT responses," that they are "always clearly labeled as sponsored and visually separated from the organic answer," and — plainly — that "ads do not influence the answers ChatGPT gives." Advertisers supply "context hints" describing the conversations they want to appear beside, and OpenAI notes those "are not exact-match keywords and do not guarantee delivery in specific conversations."

We argued earlier this year that the AI recommendation is not for sale and a hotel has to earn it. The seller has now confirmed it in writing. The sentence that names a hotel still comes out of what the model already knows — the reviews, the Business Profile, the record other people wrote about you. No budget moves it.

What a budget will buy, once the door opens, is the strip of page underneath, in front of the travelers who did not pay for the product. There is nothing to buy this month. Which makes the next few weeks the cheapest they will ever be to spend on the part that does move the answer.

Next week the auction arrives in 31 countries, and an independent can only enter it through an agency. When the door opens, the ad will run underneath an answer it cannot change, in front of the guests who declined to pay for the assistant.
