OpenAI began serving ads inside ChatGPT across 31 European markets on Monday, August 24, bringing the program’s total footprint to 40 countries and, per Digiday, marking its largest geographic expansion since the U.S. pilot started in February. Named markets include Germany, France, Spain, Italy, Poland, Sweden, Norway, Denmark, Ireland, the Netherlands, and Austria, 11 of the 31 disclosed by name.
The rollout is agency-only at launch. Buys route through OpenAI’s Ads Solutions team, technology partners, or six holding companies: Publicis, Omnicom, WPP, Havas, Dentsu, and MediaPlus. Self-service access via Ads Manager is promised “later this summer,” without a date. For anyone outside a holding-company relationship, Monday isn’t a buying event. It’s a channel-watching event.
The pitch to agencies is a numerator-and-denominator story. At Cannes, VP of Ads Dave Dugan cited 900 million weekly active users and said roughly 20% of queries show direct commercial intent. “People come to ChatGPT with goals. In the attention economy, brands have to be interesting; in the intelligence economy, they have to be useful,” Dugan told Digiday. Whether that intent converts into measurable performance is, as Search Engine Land put it, the open question.
The mechanics have moved fast for a six-month-old program. Ads appear only on the Free and Go plans; Plus, Pro, and Enterprise remain ad-free. OpenAI says advertisers don’t receive user conversations and that ads don’t influence ChatGPT’s answers. Beyond CPM and CPC, the company has added conversion optimization, geo-targeting, custom audiences, an OpenAI Pixel, a Conversions API, and third-party measurement. The $50,000 minimum that gated the U.S. self-serve tool at its spring launch has been dropped, which is the relevant precedent for what “later this summer” will look like in Europe.
Two regulatory tripwires sit on top of the expansion. The EU AI Act bans systems that use manipulative techniques or exploit vulnerabilities in ways that cause significant harm, and chatbot ads haven’t yet been tested by regulators or courts. Separately, the European Commission is weighing whether ChatGPT’s search function crosses the Digital Services Act’s 45-million-monthly-EU-user threshold for a very large online search engine. In July, Commission spokesperson Thomas Regnier told Reuters that designation was “definitely possible.”
Early auctions in new geographies tend to be thin while larger buyers evaluate. That’s the window smaller advertisers usually wait for, and it’s the one the self-serve door will open onto. It’s also the window Google’s completed August 2026 spam update has already forced some operators to think about, as organic acquisition assumptions get rewritten inside a single quarter.
