The company reportedly had 1,200 employees as of March 2025, including AI engineers and those focused on the X social network, plus 900 employees serving as "AI tutors"—though roughly 500 of those were laid off in September.

Regulatory Scrutiny and Controversy Cloud Departures
The departures come at a moment of significant regulatory scrutiny for xAI.

The timing coincides with major structural changes at the company. Elon Musk recently merged xAI with SpaceX, a move he says will enable orbiting data centers and "scaling to make a sentient sun to understand the Universe." However, some observers view the SpaceX merger as financial engineering, combining xAI's nearly $1 billion annual losses with SpaceX's roughly $8 billion in annual profits into a more IPO-ready entity. Musk had previously rolled X into a unified entity with xAI in March, when X was valued at $33 billion—25 percent less than Musk paid for the social network in 2022.
Implications for AI Talent Competition and Future Stability

While Musk frames the reorganization as calculated and necessary for scaling, the fact that several engineers followed the co-founders out the door—and that at least three are starting something new together—suggests the departures may reflect deeper internal tensions beyond routine churn at AI startups2
