OpenAI is reshuffling its leadership as Fidji Simo, the company’s CEO of AGI deployment, takes medical leave to focus on her health. The move comes alongside a broader reorganization at the company and temporarily hands product-team oversight to OpenAI president Greg Brockman.
Medical leave shifts day-to-day responsibility
Medical leave shifts day-to-day responsibility away from Simo while OpenAI manages a wider internal reset. The company has not said how long she will be away, and it has not outlined the full scope of the restructuring.
Simo’s current title is CEO of AGI deployment. Before that, she served as CEO of applications, reflecting how OpenAI has already been adjusting its leadership structure.
Greg Brockman takes over product teams
Greg Brockman takes over product teams during Simo’s absence. OpenAI said the president will handle that work while the company moves through the reorganization.
The change places one of OpenAI’s top executives in charge of a key operational area at a time when the company is still defining how its leadership is organized. The report does not indicate whether Brockman’s role will extend beyond the temporary arrangement.
Reorganization adds to leadership changes
OpenAI’s reorganization adds another layer to a leadership picture that has already shifted. The company did not provide a full breakdown of the changes, but the timing makes clear that Simo’s leave is happening in the middle of a broader internal reset.
That leaves two separate but connected developments: a medical leave for one senior executive and a temporary reassignment of product oversight to another. For now, OpenAI has only confirmed the immediate personnel changes, not the longer-term structure.
The story, reported Friday and dated Apr. 3, 2026, shows OpenAI continuing to adjust its executive lineup as it works through the reorganization.
