By Kenrick Cai OAKLAND, California, May 13 (Reuters) - OpenAI Chief Executive Sam Altman holds more than $2 billion in companies that have done business with the artificial intelligence company, a court document showed as Altman faces claims of self-dealing from state attorneys general and Elon Musk,

World's richest man Elon Musk and OpenAI CEO Sam Altman have been putting up their legal dukes for weeks now (1), since April 27. At the core of the feud is Musk's belief that he's entitled (2) to a large portion of OpenAI's eye-watering valuation,

Musk sued OpenAI, Altman and the company's president, Greg Brockman, in 2024, alleging they went back on their vow to keep the artificial intelligence company a nonprofit and follow its charitable mission. He argued that the roughly $38 million he donated to OpenAI was used for unauthorized commercial purposes.

Altman explained that he snapped after losing control of OpenAI, where he’s currently CEO of both the for-profit and nonprofit. He claimed that he seriously entertained walking away from OpenAI forever and taking Microsoft’s offer to instead spearhead an AI research wing of the tech giant, where he could get rich.
