A coalition of state attorneys general has launched a multistate investigation into OpenAI, adding significant legal pressure on the artificial intelligence company as it moves toward a public offering, according to The New York Times.

The probe is sweeping in scope. According to the Times, investigators are examining OpenAI's handling of user data, its safety practices around minors, and its advertising activities. A separate report from Bing News noted that the inquiry also extends to OpenAI's ad policies and how it handles health data.

It is not yet clear which states are participating in the coalition, according to reporting by Bing News. OpenAI acknowledged the investigation exists, saying a group of states had raised concerns spanning a wide range of its business practices.

The timing is notable. OpenAI is widely expected to pursue an IPO, and a multistate regulatory investigation of this breadth — touching consumer protection, child safety, sensitive health information, and advertising — represents exactly the kind of legal uncertainty that can complicate a company's path to public markets. Scrutiny from multiple state governments, acting in concert, also carries weight independent of any federal action and can result in binding settlements or operational changes.

State attorneys general have historically been powerful regulators of consumer-facing technology companies, having led major investigations into social media platforms over data privacy and harm to minors. Their involvement signals that concerns about AI companies are moving from academic debate into formal legal accountability.

The investigation matters because it marks one of the most significant coordinated government actions yet taken against a leading AI company — and could shape how the entire industry handles user data, minor safety, and advertising going forward.
