Two senior leaders at Elon Musk’s artificial intelligence venture xAI have stepped down, marking the latest high-profile departures from the company as it seeks to close the gap with dominant players in the global AI race. Co-founders Tony Wu and Jimmy Ba announced their resignations in posts on social media, less than three years after helping launch the firm alongside Musk.
Their exits reduce the number of original co-founders still at the company to roughly half of the initial 12, underscoring a broader internal reshaping at a time of intense competitive pressure. Neither Wu nor Ba provided specific reasons for their decisions or disclosed future plans, though both expressed gratitude to Musk in their statements.
Reports indicate that Ba’s resignation followed tensions within xAI’s technical ranks, particularly over escalating demands to boost the performance of its artificial intelligence models. Musk has been pushing the company to accelerate development in order to compete more directly with industry leaders such as OpenAI and Anthropic, which have rapidly advanced generative AI capabilities and secured major commercial partnerships.
The leadership changes come during a pivotal moment for Musk’s broader technology ecosystem. SpaceX recently announced plans to acquire xAI in a deal designed to form a combined entity valued at approximately $1.25 trillion, with intentions to take the company public later this year. The proposed listing is expected to help finance Musk’s long-term vision of building large-scale data infrastructure, including data centers positioned in space.
The departures add uncertainty to xAI’s trajectory as it balances aggressive innovation goals with organizational stability. As global competition in artificial intelligence intensifies, the company now faces the dual challenge of retaining talent while delivering technological breakthroughs ambitious enough to rival the field’s most established players.
