Fidji Simo steps down from OpenAI’s no. 2 role

Fidji Simo is leaving her full-time role as OpenAI’s No. 2 executive after a longer-than-expected medical leave. The departure creates a leadership gap as OpenAI considers a possible IPO and works to strengthen its enterprise AI business against Anthropic.

The timing underscores how critical executive stability is becoming for leading AI companies as they mature from research labs into commercial platforms. OpenAI’s next leadership moves could shape investor confidence and its ability to compete in the fast-growing enterprise market.
