Since Elon Musk’s SpaceX acquired and rebranded xAI as SpaceXAI in February, the company has lost over 50 key staff members, including top researchers and leadership. The departures raise questions about the company’s AI development focus and internal culture.
Elon Musk’s SpaceXAI has lost more than 50 researchers and engineers since February, according to reports from The Information, including key leaders in AI development. The departures have raised concerns about the company’s focus on building advanced AI models and its internal culture following the merger and rebranding.
Since the acquisition of xAI by SpaceX in February, over 50 staff members, including senior researchers and team leads, have left the company, according to The Information. Notable departures include at least 11 employees who moved to Meta and seven who joined Mira Murati’s Thinking Machine Labs. The exodus has significantly impacted the company’s core pre-training team, which is essential for developing new AI models.
Sources close to SpaceXAI indicate that these departures follow the exit of team lead Juntang Zhuang and are partly driven by internal concerns over Musk’s demanding work culture and aggressive project deadlines. Reports suggest Musk’s unrealistic timelines for model training have led to corners being cut on projects like Grok, the company’s voice AI initiative. Some employees may also be motivated by financial considerations, as SpaceX offers opportunities for employees to sell vested shares privately, and the company’s high-profile IPO prospects could provide liquidity.
Why It Matters
This staff attrition raises questions about SpaceXAI’s ability to develop competitive AI models and maintain a stable research environment. The departures could slow down or disrupt ongoing projects, affecting Musk’s broader ambitions in AI. For investors and industry watchers, the situation signals potential internal challenges at a company that aims to be a leader in artificial intelligence.

Background
Elon Musk’s xAI was launched in 2023 with the goal of competing with other leading AI firms. In February 2026, Musk acquired xAI, merging it into SpaceX and rebranding it as SpaceXAI. Since then, the company has faced internal turmoil, with reports of high staff turnover. Musk’s reputation for demanding work environments has been cited as a factor in employee departures across his companies, including Tesla and now SpaceXAI. The company’s focus on rapid development and ambitious timelines has reportedly contributed to internal dissatisfaction and attrition.
