The Republican-led House Oversight Committee has announced an investigation into OpenAI CEO Sam Altman's business dealings, adding regulatory scrutiny as the artificial intelligence company prepares for a potential initial public offering.

The congressional investigation follows reporting by The Wall Street Journal that examined Altman's various business interests and activities. The House committee's probe represents the latest regulatory challenge facing OpenAI as it navigates increasing government attention on AI development and corporate governance.

Six Republican state attorneys general have also called for the Securities and Exchange Commission to review matters related to Altman's business activities, according to sources familiar with the matter. The coordinated regulatory response suggests heightened political interest in OpenAI's operations and leadership structure.

The investigation comes as OpenAI continues to be one of the most closely watched companies in the rapidly evolving artificial intelligence sector. The company has faced previous scrutiny over its governance structure and leadership decisions, including Altman's brief removal and reinstatement as CEO in late 2023.

Details about the specific focus of the House investigation have not been disclosed, and representatives for OpenAI have not publicly responded to requests for comment about the congressional probe.
