Former OpenAI Chief Scientist Ilya Sutskever said on Monday his ownership stake in the artificial intelligence startup is worth about $7 billion, as he testified in a legal fight between Elon Musk and OpenAI. • The trial could determine the future of OpenAI, which spearheaded widespread use of AI with its ChatGPT chatbot and has been raising billions of dollars from investors to build out its computing power ahead of a potential trillion-dollar IPO. • Musk is seeking fundamental changes to the governance of the company as well as $150 billion in damages from OpenAI and Microsoft, one of its largest investors.
