US prosecutors launch multistate probe of OpenAI over data use and safety

U.S. prosecutors, led by the New York Attorney General, have issued a formal subpoena to OpenAI as part of a multi‑state investigation. The request seeks documents on the company's advertising practices, methods used to retain users, handling of consumer and health data, and safety policies for children and older adults. The inquiry follows OpenAI’s recent confidential filing for a potential initial public offering, which analysts have valued at roughly $1 trillion. OpenAI said it will cooperate with the investigation and takes the prosecutors’ concerns seriously.

The probe is viewed as part of a broader regulatory wave targeting artificial‑intelligence firms, with similar scrutiny occurring in Europe against other AI companies.
