Elon Musk, the founder and chairman of Tesla, is on course to become the first person in modern history to amass a net worth exceeding one trillion dollars this Friday, thanks to SpaceX’s stock market debut. The rocket, satellite and artificial intelligence company is debuting with a valuation of $1.78 trillion (€1.5 trillion), in a historic listing that paves the way for other blockbuster IPOs in the AI sector.
The company Musk founded in 2002 with the aim of creating a colony on Mars to make humanity a multiplanetary species is putting just under 5% of its total capital on the market — about 555.6 million shares at an initial price of $135 — to raise roughly $75 billion, according to the IPO prospectus. It is the largest initial public offering in history, ahead of Saudi oil giant Aramco’s 2019 debut, which raised about $29 billion.
The deal will shower a man who is already the richest person in the world with even greater wealth, and make him the first trillionaire in modern history (until now his fortune hovered around $700 billion). Never before has a single person accumulated so much power in history. With the increase in the value of his company, Musk will hold wealth that doubles the GDP of the economy where he was born, South Africa; it is also larger than the annual output of countries such as Sweden or Ireland, for example. The well-known virtual assistant ChatPGT says that if he spent $1 million a day, it would take him about 2,740 years to spend a trillion.

The tech magnate, who studied physics and economics at the University of Pennsylvania and later at the Wharton School of Business, plans to retain control of SpaceX by keeping 84.4% of the voting shares in his hands. The company explains in the IPO prospectus, filed with the U.S. markets regulator SEC, that Musk will retain 11.3% of the class A shares that will begin trading this Friday. Overall, the South African–born entrepreneur will hold more than 50% of SpaceX, a stake valued at $866.5 billion, more than double his total fortune before the IPO.
Musk’s main source of wealth is his space project. He founded SpaceX in 2002 with the goal of launching rockets more cheaply by using reusable components. He soon won a NASA contract to resupply the International Space Station. He quickly saw another business opportunity: those rockets could serve as a launch platform for satellites. He then created a constellation of transmitters in low Earth orbit to provide telecommunications services to the planet’s most remote and inaccessible locations. That became Starlink.
He later bought the social network Twitter for about $44 billion, renamed it X and merged it with xAI, his artificial intelligence subsidiary. Last February he carried out a merger between SpaceX and xAI in a move questioned by investors, who warned it would divert resources from the rocket and telecommunications business to the loss-making AI unit. But the merger gave SpaceX a valuation of $1.25 trillion.

The son of an engineer and a nutritionist, Musk was precocious: he left home at 17 to try to avoid military service in apartheid-era South Africa. His wealth comes from his investments in the tech companies he has created. Although Musk has been an entrepreneur since his youth — he founded an online publishing platform called Zip2, helped create PayPal with Peter Thiel, founded X.com, an online payments system, and was involved in the founding of OpenAI and many other ventures — he really became widely known with Tesla, the electric car maker, where he has a 13% stake but holds options that could easily be converted to reach 20%. Bloomberg values that stake at about $160 billion, but as a listed company it could fluctuate. Tesla has ambitious growth plans: it intends to manufacture humanoid robots of its Optimus model, unsettling human-shaped machines that it wants to mass-produce. It is also pushing for the construction of data centers and the production of microprocessors. Analysts have begun to speculate about a merger between Tesla and SpaceX because their businesses are complementary.
Adding to this fortune is his stake in Neuralink, a tech company focused on implanting devices and software in the human brain to accelerate some abilities. Although this business is still in its infancy, it has reached a value of about $3.5 billion. Musk is also the founder of The Boring Company, a firm dedicated to building tunnels and infrastructure for super-high-speed vehicles, valued at about $3.3 billion.
Not bad for a guy whose statement of intent for the IPO reads: “You want to wake up in the morning and think the future is going to be great—and that’s what being a space-faring civilization is all about. It’s about believing in the future and thinking that the future will be better than the past. And I can’t think of anything more exciting than going out there and being among the stars.”
Musk’s immense wealth has sparked debates about growing inequality on the planet, but it has also driven up wagers on prediction markets such as Polymarket and Kalshi, whose users bet on when the tech magnate will become the first trillionaire in history. According to Kalshi, one of the most popular platforms, Elon Musk had a 94% chance of reaching that milestone before 2027 (it ultimately happens this Friday).
“Elon Musk’s rise to multibillionaire status marks a new milestone for oligarchy and a dark day for democracy. But this moment of such extreme wealth concentration was not inevitable. Musk will be a government-backed multimillionaire, whose fortune was forged thanks to an era of regressive public policies: decisions manipulated by a few to increase their fortunes and overwhelmingly backed by political leaders,” said Nabil Ahmed, senior director for economic justice at Oxfam America.

Officially, Elon Musk has for years had a salary at SpaceX of $54,090. But he also benefits from stock options and other financial instruments that give him control of the company.
Musk’s net worth suffered a major drop this year during the months he served as a special government employee in President Donald Trump’s cabinet, where he headed DOGE, a project to cut state spending. His political exposure earned him many detractors and exposed him to criticism from Democrats.
