1. Last Non-Musk Cofounder Ross Nordeen Departs xAI

xAI. Ross Nordeen, the final non-Musk cofounder remaining at xAI, was abruptly cut off from company systems and removed from the internal group chat with CEO Elon Musk and hundreds of engineers. The 36-year-old former Tesla technical program manager is the eighth cofounder to exit within three months. The departures come at a critical moment as SpaceX, which merged with xAI in February, prepares for a blockbuster IPO. Corporate governance experts flagged the mass exodus as a negative signal, with Pitchbook analyst Franco Granda noting it creates “a lot of distractions” during a critical fundraising and public-listing window.
