OpenAI announced major C-suite changes in April 2026 affecting three senior executives as the company manages nearly 1 billion global users. Fidji Simo, CEO of AGI development, is taking medical leave for several weeks due to a neuroimmune condition, with co-founder Greg Brockman stepping in to manage product. CMO Kate Rouch is stepping down to focus on cancer recovery and will return to a narrower role when health permits.
