OpenAI CEO Sam Altman exits Helion Energy’s board as firms explore partnership

OpenAI Chief Executive Sam Altman said on Monday he has stepped down from the board of directors of Helion Energy, the fusion startup he has backed since 2015, as the companies start to explore working together “at significant scale”.

Altman, who is also on the OpenAI board, said the dual roles had become untenable ‌as the ⁠ChatGPT maker ⁠eyes future partnerships with Helion. In a post on social media platform X, Altman ​added that he will have a financial interest in Helion and will recuse himself ​from any deal negotiations.
