A six-month-old business goes continental
OpenAI said on Wednesday that it will extend its advertising pilot to 31 markets across Europe, a roster that includes Germany, France, Spain, Italy, Sweden, Norway, Denmark, the Netherlands, Ireland, Belgium, Austria, Poland, the Czech Republic and Portugal. The ads start appearing on Aug. 24. Until now the pilot had run in only nine countries, among them the United States, Canada, Australia, New Zealand, the United Kingdom, Japan, South Korea, Brazil and Mexico. In roughly six months, the ChatGPT maker has moved advertising from a domestic experiment to a business spanning two continents.
The pace is the story. Colin Fleming, the former ServiceNow executive who now serves as OpenAI’s enterprise chief marketing officer, told reporters that ad revenue has grown more than 25% since the start of August and called the European rollout a material expansion. He framed the opportunity in terms of reach and intent. ChatGPT now counts roughly one billion weekly active users, and about 20% of them, by OpenAI’s reading, show commercial intent.
The audience marketers have wanted to buy
That commercial-intent figure is what turns a chatbot into a media property. Someone asking ChatGPT which running shoe suits flat feet, or how two mortgages compare, is signaling purchase consideration in a way a scrolled feed rarely captures. OpenAI is selling proximity to that moment, and proximity to intent is the most expensive real estate in advertising. It is the same logic that made Google Search and Amazon’s retail-media network into profit machines, now transplanted into a conversational surface.
The ads sit in a labeled, visually distinct space beside relevant conversations. OpenAI says its systems keep content generation and ad serving on separate tracks, so the ad engine receives contextual signals about a conversation’s topic and apparent intent rather than the full transcript. For now the ads reach only users on the free and lower-cost Go plans; subscribers on the Plus, Pro and Enterprise tiers remain ad-free, protecting the premium experience the company charges for.
Europe rewrites the rules
The expansion is less a copy-paste than a stress test, because Europe does not let advertisers assume consent. Under the General Data Protection Regulation, personalized advertising requires explicit opt-in, the inverse of the United States, where ads run by default and users may opt out. OpenAI is building the consent machinery to match, asking European users for permission before tailoring what they see.
That single difference shapes the economics. Consent rates decide how much of the audience can be targeted with precision, and therefore how much a thousand impressions are worth. A billion weekly users mean little to a performance buyer if only a sliver agree to personalization. OpenAI’s task in Europe is to show that an assistant people trust with sensitive questions can also ask them to accept advertising without eroding that trust. Get the ask wrong and the consent rate collapses; get it right and the company has a template for monetizing attention inside the most regulated market in the world.
A revenue engine assembled at speed
The European move fits a compressed timeline. OpenAI first tested ads in the United States in February, then reached the United Kingdom, Mexico, Brazil, Japan and South Korea by mid-August. The commercial organization has been rebuilt in parallel. Chief revenue officer Denise Dresser recently stepped down, with Dali Rajic stepping in, and Fleming’s enterprise CMO seat underscores how central go-to-market has become. All of it unfolds against reporting that OpenAI is moving toward a public offering, where a credible, fast-growing advertising line would help support the company’s valuation.
For a business that spent its early years insisting it was not an advertising company, the reversal is sharp. Advertising is now among the fastest-growing things OpenAI does, and the company is no longer hedging about it.
What it means for marketers
A new channel is opening, and it behaves unlike the ones marketers know. Access starts through OpenAI’s ad-solutions team, agency partners and technology partners, with self-serve buying through an Ads Manager promised later. Early advertisers will buy against conversational context rather than the demographic and behavioral cohorts that define social platforms, which means creative, targeting and measurement conventions all have to be rethought for a surface where the feed is a dialogue.
The strategic question is larger than any single media plan. If people increasingly begin product research inside an assistant, that assistant becomes a gatekeeper to demand, and the brands that learn its rules first will hold an advantage that compounds. Real risks remain: brand safety beside unpredictable generated answers, measurement standards that do not yet exist, and the chance that users reject ads in a space they treat as a trusted advisor. Europe, with its consent-first posture, is where the durability of the model gets tested. The marketers watching Aug. 24 are not merely evaluating a new inventory source. They are watching whether advertising can live comfortably inside the tool a billion people now ask for advice.
