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.
