SpaceX IPO prospectus reveals deep intertwining with Musk's companies, Tesla holds nearly 19 million shares of SpaceX

SpaceX's initial public offering (IPO) prospectus (Form S-1) shows that there is extensive business and equity overlap among several companies owned by Elon Musk. In this 330-page document, "Tesla" is mentioned 87 times, "xAI" appears 356 times, "X" appears 267 times, and "The Boring Company" and "Neuralink" are mentioned 7 times and 3 times, respectively. In terms of equity, Tesla holds approximately 19 million shares of SpaceX Class A common stock, accounting for less than 1%. In February of this year, after Musk merged his artificial intelligence company xAI with SpaceX, Tesla's shares in xAI were converted into SpaceX shares.

In terms of business transactions, SpaceX purchased $131 million worth of Cybertrucks from Tesla at the manufacturer's suggested retail price. Previously, it was reported that SpaceX purchased 1,279 Cybertrucks in the fourth quarter of 2025, and the prospectus suggests that the actual purchase quantity may be higher. Additionally, SpaceX purchased $697 million worth of Megapack energy storage batteries from Tesla in 2024 and 2025 to stabilize peak demand at its Colossus I and II data centers located in Memphis, Tennessee.

The prospectus also reveals the financial pressures brought about by the merger. SpaceX will allocate approximately 60% of its capital expenditures (about $20 billion) to xAI in 2025, but xAI's revenue grew only 22% year-over-year last year, and it incurred losses amounting to billions of dollars. In the risk factors section, SpaceX explicitly lists Musk himself as a major risk. The document states that the company "is highly dependent on Musk's continued services," and his leadership, vision, and technical expertise are crucial to the company's future.

At the same time, SpaceX acknowledges that Musk is not always 100% focused on company affairs, and several of his companies may compete with each other or encroach on each other's business in certain areas. Musk is not restricted from engaging in activities that may directly compete with SpaceX, which could lead to potential conflicts of interest in the future. Furthermore, Musk's statements and actions may have positive or negative impacts on the company's business, customer relationships, regulatory relationships, or stock price.
