Sam Altman-backed fusion startup Helion in talks to sell power to OpenAI

Sam Altman is stepping down as Helion's board chair and the companies are reportedly negotiating a deal for OpenAI to purchase 12.5% of Helion's power output. The 12.5% offtake could provide OpenAI with secured power and create a recurring revenue stream for Helion, with implications for Helion's valuation and project financing. This is a company-level governance and strategic-supply development — portfolio managers should watch for deal terms (price, duration) and any follow-on governance or financing announcements.
