SpaceX IPO reveals Elon Musk as biggest risk factor

SpaceX's IPO filing (Form S-1) paints a complex picture of the rocket company's finances and its deep ties to Elon Musk's empire. The 330-page document reveals that Tesla owns nearly 19 million shares of SpaceX Class A common stock (less than 1%), and that SpaceX purchased $131 million worth of Cybertrucks and $697 million in Tesla Megapacks for its data centers. The filing also shows that after merging with xAI in February, SpaceX directed about 60% of its 2025 capital spending—roughly $20 billion—toward xAI, which is losing money despite 22% revenue growth. Other Musk companies appear throughout: The Boring Company paid $1.2M in office leases to SpaceX, and SpaceX spent $1M for a Boring Company tunnel. xAI is mentioned 356 times, X 267 times, Tesla 87 times, Boring Company 7 times, and Neuralink 3 times.

The most striking disclosure is that SpaceX lists Elon Musk himself as a primary risk factor. The filing states SpaceX is 'highly dependent on the continued services of Mr. Musk' and acknowledges that his leadership is critical but not exclusive to SpaceX. It admits Musk's other businesses may compete with or cannibalize SpaceX, and that Musk is not restricted from acting in ways that conflict with SpaceX's interests. For investors, this means the company's greatest asset is also its greatest liability—a CEO with divided attention across Tesla, xAI, X, Neuralink, and The Boring Company, whose personal controversies could impact the stock. The IPO values SpaceX at $1.25 trillion post-merger, making it a high-stakes bet on Musk's ability to manage these tensions.
