OpenAI switches ChatGPT Ads on across 31 European markets today, six months after the U.S. pilot began in February and roughly four months after the April version of the platform that Jellyfish’s Victor Batista says “is not the platform that was released as a pilot in April at all, it’s actually grown massively.” Germany, France, Spain, Italy, Poland, the Nordics, Ireland, the Netherlands, Austria, Switzerland and the Benelux round out the map. It’s the largest single geographic expansion of OpenAI’s ad business to date, and the terms of entry matter more than the headline.

For now, buying is gated. Advertisers in the new markets place spend through six agency holding groups: Publicis, Omnicom, WPP, Havas, Dentsu and MediaPlus. The self-serve Ads Manager OpenAI announced is scheduled for “later this summer,” with no specific date. If you don’t already sit inside one of those agency rosters, today isn’t a spend moment. It’s a research window.

The audience pitch is where things get interesting. At Cannes, OpenAI ads VP Dave Dugan cited 900 million weekly active users and said roughly 20% of queries show direct commercial intent. Search Engine Land’s read is that a conversation with an assistant about what to buy is a richer intent signal than a keyword or a passive social impression, and that framing is what agencies are quietly repricing against.

Ads at launch reach only Free and Go plan users; Plus, Pro and Enterprise stay ad-free. Targeting is contextual only, running on current conversation topic, city-level location, device, time of day and language, under GDPR’s legitimate-interest basis. Personalized ads require a separate explicit opt-in.

For a 5-to-30-person team selling into Europe, the useful work this week isn’t buying inventory. It’s stress-testing whether your landing page and offer are sharp enough to convert someone who arrives mid-decision rather than mid-scroll. Yesterday’s channel-readiness rundown covered that checklist; the launch-day breakdown has the market-by-market map.

The last time a new intent channel opened at this scale, the auction stayed cheap only until the self-serve door opened.
