“Altman is Helion’s board chair and largest investor, The Washington Post reports, and may have been involved in brokering Helion’s power purchase agreement with Microsoft.”
Helion promises Microsoft at least 50 megawatts of fusion power by 2028. It has not yet hit net energy gain, and it needs helium-3, a rare isotope with no commercial supply. Sam Altman chairs Helion’s board and is its largest investor. Microsoft has billions in OpenAI. A fusion deal brokered inside one man’s portfolio is a press release with a deadline.
