OpenAI’s non-profit board removed Sam Altman as chief executive on 17 November 2023, saying he had not been consistently candid with it, and named Mira Murati interim CEO; Greg Brockman stepped down as chair. Altman returned as CEO, confirmed on 29 November with a new initial board of Bret Taylor as chair, Larry Summers and Adam D’Angelo. Microsoft took a non-voting observer seat, and the board commissioned WilmerHale to review the events.

Why it matters

The non-profit board that controls OpenAI was largely replaced within two weeks of firing its chief executive, and Microsoft, its largest investor, gained a seat as observer.
