Elon Musk is preparing to take SpaceX public in what would be the largest initial public offering in history—a $75 billion debut that reads less like a corporate prospectus and more like a script for a Hollywood science fiction film.
If the offering succeeds at its proposed $135 per share, SpaceX would be valued at $1.77 trillion, making it the sixth most valuable company in the world, equal to Broadcom and trailing only giants like Nvidia, whose market cap sits around $4.9 trillion. The sheer scale of the numbers reflects Musk's stated mission: to make humanity an interplanetary species by establishing a lunar base and eventually colonizing Mars.
The 555,555,555 shares being sold would generate more than double the previous record IPO haul. Saudi oil giant Aramco held that record with $26 billion when it went public in 2019. For context, SpaceX's planned fundraising exceeds the economic output of many nations.
Musk's own position would be transformed by the listing. With a net worth of $786 billion as of mid-June, the SpaceX founder could become the world's first trillionaire, depending on how the stock performs. His wealth would dwarf the combined fortunes of billionaires ranked two through five on the Forbes list—Google co-founders Larry Page and Sergei Brin, Amazon founder Jeff Bezos, and Oracle Chairman Larry Ellison—whose collective net worth stands at $1.02 trillion.
The IPO prospectus reveals spending at a staggering scale across SpaceX's operations. Yet Musk's ambitions are constrained by far more than financial considerations. He aims to deploy 100,000 next-generation Starlink satellites into orbit to expand global internet connectivity. SpaceX currently operates about 9,600 satellites in space; to put that in perspective, UPS maintains a fleet of 135,000 delivery vehicles, including motorcycles.
Control of the company will remain firmly in Musk's hands. He owns more than 90% of SpaceX's Class B shares, which grant ten votes per share, giving him 82.4% total voting power even after the public offering. He also holds a 12.3% stake in Class A shares, which carry one vote each.
Perhaps most striking are Musk's personal incentives baked into his compensation package. He stands to receive additional benefits once SpaceX establishes a Martian colony with at least 1 million inhabitants—a figure that underscores the audacity of his vision. Currently, there are no demonstrated capabilities for transporting a single person to Mars, let alone one million. For scale, global cities with populations around 1 million include Ottawa, Prague, and San Jose, California.
This IPO represents more than a financial milestone. It signals a moment when space exploration—once the exclusive domain of government agencies—has become a commercial venture ambitious enough to reshape markets and potentially human civilization itself. Whether the stock market's appetite for Musk's cosmic vision proves as boundless as the universe itself remains to be seen.
