Half of xAI's Founding Team Has Departed
Elon Musk's AI startup, xAI, has reportedly lost half of its founding team since its inception. The departures highlight the intense volatility and potential for leadership turmoil within well-capitalized AI companies as they navigate strategic and cultural challenges.
- The six departed co-founders include prominent AI researchers like Jimmy Ba, a former University of Toronto professor who studied under Geoffrey Hinton, and Tony Wu, who previously worked at Google and was responsible for foundational models at xAI. Other departed founders are Igor Babuschkin, Kyle Kosier, Greg Yang, and Christian Szegedy, with backgrounds at DeepMind, OpenAI, and Microsoft Research. - The departures of Ba and Tony Wu on February 11th and 10th, 2026, respectively, followed a major restructuring of the company after its merger with SpaceX. This merger valued SpaceX at $1 trillion and xAI at $250 billion. - Elon Musk addressed the exits during an all-hands meeting, stating the reorganization was necessary for the company to scale effectively and that some people are better suited for the early stages of a startup. He framed the departures as a consequence of structural changes needed to "improve speed of execution." - The restructuring organizes xAI into four core teams: the Grok chatbot, coding systems, an "Imagine" video generator, and a "Macrohard" project focused on computer simulation and business modeling. - Sources suggest the departures may be linked to a combination of factors including the high-pressure work environment, which leaders at an all-hands meeting described as a "grind," and a significant financial opportunity for early employees to sell vested equity following the SpaceX acquisition. - One of the departed co-founders, Igor Babuschkin, left in August 2025 to start his own AI safety fund, a move that followed controversies around the xAI chatbot Grok making far-right statements. - The original stated goal of xAI at its founding in 2023 was to "understand the true nature of the universe." The founding team was largely recruited from other major AI labs like DeepMind, OpenAI, and Google.
