OpenAI launches ads on ChatGPT in Europe amid slowing revenue growth

OpenAI is expanding its ChatGPT advertising business to 31 European markets on August 24, 2026, partnering with major agencies like Publicis and WPP. The expansion comes as OpenAI faces pressure to offset massive infrastructure costs; the company reported a tepid 18% quarter-over-quarter revenue growth to $6.7 billion in Q2 2026, alongside deepening operating losses. To navigate strict European GDPR rules, OpenAI updated its privacy policies to secure user trust while chasing a $100 billion revenue target.

ChatGPT European ad launch

• ▪OpenAI will begin serving advertisements to ChatGPT users across 31 European markets, including Germany, France, Spain, Italy, Poland, Sweden, Norway, Denmark, Ireland, and the Netherlands, on August 24, 2026.
• ▪OpenAI stated that advertisements on ChatGPT will be clearly identified, will not influence ChatGPT's responses, and will not grant advertisers access to user conversations.

OpenAI revenue growth slowdown

• ▪OpenAI's operating margin sank further into the red during the second quarter of 2026, deepening its losses ahead of a much-anticipated initial public offering.
• ▪OpenAI reported to investors that its revenue grew by 18% from the first quarter to the second quarter of 2026, reaching $6.7 billion in the three months ended in June, up from $5.7 billion.
• ▪OpenAI has told investors it expects to reach $100 billion in revenue within four years to help offset infrastructure costs that far outweigh its current revenue.

Ad platform expansion timeline

• ▪OpenAI's global advertising business reached its six-month milestone in August 2026, having launched as a United States pilot in February 2026 before expanding to Canada, Australia, New Zealand, the United Kingdom, Mexico, Brazil, Japan, and South Korea.
• ▪OpenAI's global head of ads, Dave Dugan, stated at Cannes that ChatGPT had passed 900 million weekly active users, with roughly 20% of queries showing direct commercial intent.

GDPR compliance requirements

• ▪OpenAI updated its privacy terms on June 4, 2026, and posted a new European Union privacy policy on August 14, 2026, detailing how it will process user data across the region once ads go live.
• ▪The General Data Protection Regulation in Europe requires explicit consent for personalized targeting unless a company can prove a legitimate interest, making the European advertising expansion slower for OpenAI.

Agency partnership distribution model

• ▪Advertisers in the newly added European markets can purchase ChatGPT advertisements starting August 24, 2026, through agency partners Publicis, Omnicom, WPP, Havas, Dentsu, and MediaPlus.
• ▪OpenAI launched its advertising business in the United Kingdom in June 2026 through agency representatives rather than self-serve tools, a distribution pattern it is maintaining for the broader European launch.
