Paris, France – September 17, 2026 – Already actively engaged in this space for more than six months, particularly in the United States, international group Cosmo5 has been selected as an official OpenAI partner as ChatGPT advertising launches today across 31 new markets, including Spain, Italy, Germany, the Netherlands and, of course, France.

Cosmo5 has already mobilized 10 of its clients across France and Spain to be among the first advertisers to launch campaigns on the platform and gain early insights from this new advertising environment. These include Bouygues Telecom, Cultura, TotalEnergies and Carrefour in France, as well as Repsol, Fotocasa and Santalucia in Spain.

During this initial rollout phase, which is expected to last several weeks, advertisers can access ChatGPT Ads only through OpenAI’s agency and technology partners. Cosmo5 will support its clients in setting up, launching and managing their first advertising campaigns on the platform.
