Final xAI Cofounder departs as Musk rebuilds AI unit ahead of SpaceX IPO
Ross Nordeen, the last remaining cofounder of Elon Musk's xAI, has left the company as Musk reorganizes xAI ahead of SpaceX's planned IPO. Nordeen served as Musk's right-hand operator and helped coordinate priorities across the company; his departure follows a wave of leadership exits since SpaceX acquired xAI and Musk said the unit is being rebuilt from the foundations up. The reshuffle coincides with ongoing hiring and restructuring, including new senior recruits from Cursor, as xAI pursues growth in a sector valued around $250 billion.
