OpenAI is expanding its ChatGPT advertising pilot to 31 European markets, including Germany, France, Spain, Italy, the Netherlands and several Nordic countries.
The rollout significantly broadens a programme previously available in nine markets including the US, UK, Canada, Japan and Brazil.
OpenAI says advertising revenue has grown more than 25% since the start of August. ChatGPT now has around one billion weekly active users, with roughly 20% displaying commercial intent, highlighting the potential scale of its emerging advertising business.
