Core Event: Complete Exodus of xAI Co-Founders
Elon Musk's artificial intelligence startup, xAI, has witnessed the departure of all its original co-founders, culminating in the exits of Manuel Kroiss and Ross Nordeen. This significant turnover follows a series of departures that began shortly after SpaceX acquired xAI in February 2026, valuing the company at approximately $250 billion. Musk has acknowledged that xAI "was not built right the first time around," prompting a complete organizational overhaul.
Background & Context: Acquisition and Restructuring
In February 2026, SpaceX acquired xAI, merging the two entities under a single corporate umbrella. This acquisition was part of a broader strategy as SpaceX prepares for a potential initial public offering (IPO) that could target a valuation of $1.75 trillion. Following the acquisition, Musk reorganized xAI, which has since experienced significant leadership turnover and layoffs, particularly among teams focused on AI projects.
Key Figures & Groups: The Co-Founders
The original team of eleven co-founders included notable figures such as Jimmy Ba, Guodong Zhang, and Christian Szegedy, all of whom have now left xAI. Ross Nordeen, who served as Musk's "right-hand operator," and Manuel Kroiss, who led the pretraining team, were the last to depart. Their exits reflect a broader trend of instability within the company, which has struggled to maintain its leadership amid ongoing restructuring.
Criticism & Opposition: Concerns Over Leadership and Culture
Critics argue that the mass exodus of co-founders indicates deeper organizational issues within xAI, rather than mere financial instability. The departures suggest that the company's research culture has deteriorated, making it difficult to retain top talent in a highly competitive AI labor market. Musk's management style, which has proven effective in hardware engineering, appears less suited for research-driven environments where stability and leadership are crucial.
Official Statements & Responses: Musk's Acknowledgment of Challenges
Musk has publicly stated that xAI's AI coding tools "simply did not work," emphasizing the need for a complete rebuild of the company's systems. This admission has been interpreted as a validation of the co-founders' decisions to leave, as it undermines the incentive for key researchers to remain amid uncertainty.
What's Next: Future of xAI and Talent Acquisition
Despite the challenges, xAI remains a well-funded player in the AI sector, with access to significant resources from SpaceX. The company is actively recruiting new talent, having recently onboarded several senior leaders from other AI firms. However, the question remains whether xAI can successfully rebuild its research capabilities without the foundational leadership that has departed.
