Why OpenAI’s Top Leaders Are Leaving and What It Means for the AI Industry

OpenAI’s three key employees—Chief Technology Officer Mira Murati, Chief Research Officer Bob McGrew, and Vice President of Research Barret Zoph—have announced they will leave the ChatGPT maker.

Murati described the decision as “hard” but felt it was the right moment, saying she wants time and space for her own exploration.

The other two echoed a need for a break; Zoph called it a personal decision based on how he wants to develop the next stage of his career.

Last year, during Sam Altman’s brief ouster and rehiring, Murati briefly served as OpenAI’s CEO.

Altman praised Murati on Twitter, noting her important role in OpenAI’s progress over the past six and a half years, and insisted the departures were independent choices.

Gartner analyst Jason Wong observed that the exit of founding and senior engineering leaders signals OpenAI’s reshaping under Sam’s vision, including its shift toward a for‑profit model, which could affect its partnership with Microsoft and create uncertainty for businesses investing in generative AI.

AI expert Dr. Gary Marcus described the situation as a “slow‑motion train wreck.”

Co‑founder Ilya Sutskever resigned earlier this year, and co‑founder Greg Brockman announced a leave of absence until year‑end; now Murati is also departing.

The series of exits resembles a soap‑opera plot about an over‑valued AI company.

According to Reuters, OpenAI is planning to regain control from its nonprofit board and restructure as a for‑profit entity, a move that could grant Altman equity in the newly profit‑oriented company.

Recent reports suggest OpenAI’s valuation has risen to $150 billion, up from $90 billion a year ago, amid concerns about operating losses, lack of a clear moat, competition from free offerings by Meta, and pending lawsuits.

Marcus warned that despite the high valuation, GPT‑5 has not been released, Sora remains unavailable, and the company posted a $5 billion loss last year, urging investors to question the fundamentals.

When asked for comment, OpenAI said it remains focused on building AI that benefits everyone and continues to work closely with its board, emphasizing that the nonprofit remains central to its mission, though it did not clarify the actual control structure.
