OpenAI Fires Sam Altman, Says He Wasn't 'Consistently Candid'

Sam Altman is out at OpenAI. Not a planned departure, not a mutual agreement—the board fired him, effective immediately. The company announced Friday that its CEO and co-founder will leave both his executive role and his seat on the board of directors, following what it called a ‘deliberative review process.’ The board’s statement is remarkably blunt for a corporate press release: Altman was not ‘consistently candid in his communications,’ which hindered the board’s ability to do its job. They no longer have confidence in his leadership. That’s a stunning rebuke for a founder who, until today, was the public face of the AI revolution.

Mira Murati, OpenAI’s chief technology officer, steps in as interim CEO. She’s been with the company for five years and already oversees research, product, and safety—a portfolio that makes her the obvious internal choice. The board praised her ‘unique skill set’ and deep understanding of the company’s operations, values, and governance. She’ll hold the fort while a formal search for a permanent replacement gets underway. The board emphasized they expect a ‘seamless transition,’ but anyone who’s watched a high-profile CEO get abruptly dismissed knows these things are rarely smooth.

There’s another shoe dropping here: Greg Brockman, OpenAI’s president and co-founder, is stepping down as chairman of the board. He’ll stay at the company and report to the new CEO, but losing the chairmanship alongside Altman’s firing suggests this wasn’t a one-person problem. The board now consists of chief scientist Ilya Sutskever and three independent directors—Quora CEO Adam D’Angelo, tech entrepreneur Tasha McCauley, and Helen Toner from Georgetown’s Center for Security and Emerging Technology. Notably, the independent directors don’t hold equity in OpenAI, a structural quirk that goes back to the company’s 2019 restructuring.

That restructuring looms over all of this. OpenAI started as a pure nonprofit in 2015, then built a capped-profit arm to raise capital while keeping the original mission intact: ensuring artificial general intelligence benefits all humanity. The board’s statement nods to this, saying the company has seen ‘dramatic growth’ but the governance responsibility remains the same. Reading between the lines, it sounds like the tension between that growth and that mission finally snapped. What Altman wasn’t candid about remains unspecified. But for a board dominated by independent directors with no financial stake to fire the CEO of tech’s most watched company, the disagreement must have been fundamental.
