All xAI co‑founders have exited
Elon Musk’s xAI has now seen every original co‑founder depart as SpaceX prepares an IPO — the full turnover raises fresh questions about founder dynamics, governance, and succession at a high‑profile AI firm. The exodus is a stark reminder that boards need robust CEO‑succession and retention plans in fast‑moving AI companies. (thenextweb.com)
Business Insider reported that Ross Nordeen — described as a close operational lieutenant who followed Musk from Tesla — left xAI this week, completing the exit of the original non‑Musk co‑founders first recruited in 2023. (businessinsider.com) Manuel Kroiss, who led xAI’s pretraining team, notified colleagues of his departure earlier this week, joining a list of technical co‑founders who left across 2025–2026 including Igor Babuschkin, Christian Szegedy, Greg Yang, Tony (Yuhuai) Wu and Jimmy Ba. (thenextweb.com) Igor Babuschkin publicly left xAI on August 13, 2025 and said he would form Babuschkin Ventures to back AI safety research, a concrete example of founders converting technical leadership into new venture activity. (cnbc.com) SpaceX formally announced its acquisition of xAI on February 2, 2026 and the combined entity was described in coverage as valuing the deal and enlarged company at roughly $1.25 trillion. (spacex.com) Bloomberg reported that SpaceX is lining up investor briefings for April as part of aggressive IPO preparation, a timetable that places the governance and disclosure functions of any board under immediate market scrutiny. (bloomberg.com) Elon Musk acknowledged on X on March 12, 2026 that “xAI was not built right first time around, so is being rebuilt from the foundations up,” a public admission that followed multiple senior departures and a wave of reorganizations. (cnbc.com) Tech reporting noted that an IPO will elevate investor focus on leadership continuity and institutional knowledge loss after the co‑founder exodus, underscoring specific audit and nomination committee tasks tied to disclosure and succession planning. (techcrunch.com) xAI’s pattern of founders leaving to start new firms or join other projects while SpaceX prepares a record‑scale listing creates a narrow window in which compensation committees must decide whether targeted retention awards or transition agreements are cost‑effective versus the market risk of accelerated turnover.
