OpenAI is significantly expanding its advertising business, announcing that it will introduce advertising services for ChatGPT users on Free and Go plans across 31 European markets. In January of this year, OpenAI first disclosed its plan to introduce ads for ChatGPT in the U.S. market and officially launched a pilot project in February, subsequently expanding it to Canada, Australia, New Zealand, and other regions. Now, just six months after the initial U.S. ad test launch, OpenAI is accelerating its commercialization process. With this expansion into the European market, ChatGPT's advertising services now cover 35 countries worldwide.
