Elon Musk's SpaceX is preparing an internal stock transaction that would value the company at approximately $400 billion, according to sources familiar with the matter. This landmark deal represents both a rapid valuation surge for the rocket and satellite manufacturer and reinforces its status as the world's most valuable private startup. The transaction price of $212 per share marks a substantial increase from December's $185 per share level, which had previously valued SpaceX at $350 billion. Company representatives haven't responded to requests for comment.

Beyond its high-profile Starship rocket program and core Falcon rocket series, SpaceX operates the Starlink satellite internet division. Insiders reveal this segment generates over half of the company's annual revenue. As part of the arrangement, certain shareholders will gain the opportunity to divest their holdings—an increasingly common practice among privately held startups seeking to provide liquidity for early employees and investors while maintaining long-term private status.

Additional sources indicate SpaceX will repurchase up to $1.25 billion worth of shares from employees and existing stakeholders. Concurrently, Musk is pursuing funding for his artificial intelligence venture XAI Holdings, which is reportedly negotiating a $10 billion capital raise at a potential valuation reaching $200 billion. This dual-track financial activity underscores Musk's expanding technological ecosystem while spotlighting SpaceX's extraordinary market trajectory.
