OpenAI President and Cofounder Greg Brockman revealed in federal court testimony on Monday that he holds a substantial ownership stake in the artificial intelligence company, describing himself as one of its largest individual stakeholders.

Brockman disclosed his significant financial interest in OpenAI while defending his motives regarding the company's planned restructuring from a nonprofit to a for-profit entity. The revelation came during court proceedings where Brockman was called to testify about the AI lab's corporate structure and governance.

The OpenAI executive characterized his involvement in building the company as requiring considerable personal investment, referring to the "blood, sweat, and tears" he has put into the organization since its founding. Brockman has served as president of OpenAI since its establishment and has been instrumental in the company's development.

The disclosure of Brockman's substantial stake comes as OpenAI continues to navigate questions about its corporate structure and the potential conversion from its original nonprofit status to a for-profit model. The company has grown significantly in value following the success of its ChatGPT product and other AI technologies.

The federal court appearance represents part of ongoing legal proceedings involving OpenAI's corporate governance and restructuring plans. The company has faced scrutiny over its organizational changes as it has evolved from a research-focused nonprofit into a major commercial player in the artificial intelligence sector.
