OpenAI Brings ChatGPT Ads to 31 European Markets as It Chases a $100 Billion Dream

Six months after lighting up its first sponsored messages in the United States, OpenAI is taking its advertising business across the Atlantic. On August 19, the company announced that ChatGPT Ads will expand to 31 European countries on Monday, August 24 — giving marketers access to free and Go-tier users in Germany, France, Spain, Italy, Poland, Sweden, Norway, Denmark, Ireland, the Netherlands, and more.

The move marks the most aggressive phase yet of OpenAI’s transformation from a pure subscription business into a full-fledged advertising platform, and it arrives at a moment when the company’s financial calculus has never been more urgent.

What’s launching on August 24

The expansion covers the free tier of ChatGPT and the low-cost Go plan, which costs eight euros (about $9.30) a month in Europe. Premium subscribers — Plus, Pro, and Team — will continue to see an ad-free experience. Only a small percentage of ChatGPT’s nearly one billion users pay for premium tiers, which means the overwhelming majority of the product’s audience is about to become monetizable inventory.

The rollout pattern mirrors what OpenAI has done elsewhere: ads in the new European markets will be sold through agency holding groups rather than self-serve tools. Advertisers can buy placement through Publicis, Omnicom, WPP, Havas, Dentsu, and MediaPlus. A self-serve buying platform for small businesses is promised but has no launch date; the U.S. version debuted this spring with a $50,000 minimum spend, a threshold that has since been dropped.

“This expansion gives marketers across Europe a new way to reach people while they are actively exploring, comparing, and making decisions,” OpenAI said in its announcement.

The GDPR tightrope

Europe was always going to be the hardest market for OpenAI’s ads business. The General Data Protection Regulation requires explicit consent for personalized targeting unless a company can prove legitimate interest — a hard case to make in an AI chatbot context.

OpenAI has been laying the regulatory groundwork for months. On June 4, it updated its privacy terms for the region, and on August 14 it posted a dedicated EU privacy policy detailing how user data will be processed once ads go live. The company has committed that personalized ads will only be served to users who explicitly opt in — an approach that starts where Meta’s consent-or-pay battles ended, but with consent as the default gate rather than a forced choice.

In its statement, OpenAI emphasized that conversations remain private from advertisers, that no customer data is sold, and that “ads in ChatGPT are always clearly labelled and separate from ChatGPT’s answers, and advertising does not influence the answers ChatGPT provides.”

That last claim — answer independence — is the trust wager underpinning the entire business. Critics warn that users may begin distrusting ChatGPT’s content if they sense responses are being shaped by advertisers with products to push. Anthropic, meanwhile, has leaned hard into the opposite positioning, making its pledge to remain ad-free a central marketing message.

A 900-million-user attention market

The commercial logic is straightforward. At the Cannes Lions festival in June, OpenAI’s vice president of ads, Dave Dugan, said ChatGPT had passed 900 million weekly active users, with roughly 20% of queries showing direct commercial intent — people asking what laptop to buy, which VPN to choose, when to book flights — and a wider band of upper-funnel questions, like the best time to visit the Alps, that predict future purchases.

“In the attention economy, brands have to be interesting; in the intelligence economy, they have to be useful,” Dugan said in this week’s statement. “ChatGPT Ads is designed to help businesses contribute in a meaningful way when someone is deciding to take action.”

The product has evolved quickly. Since launch, the platform has added a cost-per-click pricing model that now accounts for most ad spend, an ads manager, measurement tools, and product carousels. Dugan, who joined OpenAI in March from a rival ad-tech firm, described the product at Cannes as “19 weeks old, like a baby.” Two months later, it has grown into 31 more markets.

The expansion also completes a rapid geographic march: after the February U.S. pilot, ads arrived in Canada, Australia, New Zealand, the U.K. (June), Mexico, Brazil, Japan, and South Korea — roughly one new market batch per month.

The $100 billion question

The urgency traces back to money. OpenAI is carrying infrastructure costs that far outweigh its revenue, and it is preparing for an initial public offering that could value it at nearly $1 trillion — a listing that will require a credible path to profitability. The company has told investors it expects $100 billion in revenue within four years, a target that took Meta 17 years to reach. Skeptics call that unrealistic. Everything OpenAI has done since February argues otherwise: a pilot, an ads manager, new markets added roughly monthly, ad-tech partnerships, measurement tools, a shift toward cost-per-click bidding, and heavyweight hires from rivals.

Europe is the prize that makes the math plausible. The continent holds some of the world’s largest advertising markets, and with Google and Meta costs rising across EMEA, buyers are actively looking for alternatives. “If OpenAI can sway dollars away from Google and Meta, they could make an instant impact, especially if they can focus on the intent-based search behavior,” said Shamsul Chowdhury, SVP of paid media at Zeno Group. “The big watchout will be how AI is policed in EMEA; if OpenAI can overcome the AI Act and GDPR rules of engagement, they may have a solid revenue stream to grow.”

There are cautionary notes from inside the industry. “This is very much unproven. This is very new, and they are building at a very fast pace,” said Victor Batista, senior director of paid media at Jellyfish, whose clients are part of the pilot. “The ad platform that we are using now is not the platform that was released as a pilot in April at all — it’s actually grown massively.”

What to watch

Three things will determine whether Europe becomes a revenue engine or a regulatory headache. First, opt-in rates: if few European users consent to personalization, the inventory’s value drops sharply, and OpenAI will have to lean on contextual and intent-based targeting that doesn’t rely on personal data. Second, the EU AI Act’s transparency rules — enforceable since August 2 — which require clear disclosure of AI-generated content and could shape how sponsored answers must be labeled. Third, competitive response: Anthropic’s ad-free positioning is increasingly a stated differentiator for Claude, and Google is racing to defend its search-ad franchise against chat interfaces.

For now, OpenAI is betting that it can build the first great advertising business native to the AI era — one where usefulness, not attention, is the currency. On August 24, a continent of ChatGPT users finds out whether that bet includes them.
