A coalition of U.S. state attorneys general has opened a sweeping investigation into OpenAI, serving the company with a subpoena. The subpoena demands documents related to advertising practices, user engagement strategies, and data handling procedures, according to a source cited by Reuters. The investigation, reported on June 12, 2026, marks a significant regulatory action against the leading AI firm.

The exact number of states involved and their identities have not been disclosed. The subpoena is part of the investigation's broad scope, which appears to address potential concerns over how OpenAI markets its products and manages user information. The company has not responded to requests for comment on the investigation.

The probe adds to existing scrutiny of AI companies by U.S. regulators. It follows previous questions about OpenAI's business practices. The outcome could have implications for AI industry standards regarding transparency and user protection. The investigation is ongoing.
