SpaceX completed the largest IPO in history, raising $75 billion at $135 per share and achieving a $1.8 trillion valuation, propelling Elon Musk toward trillionaire status while sparking debate over AI-driven market valuations.
SpaceX made history on Thursday with the largest initial public offering ever recorded, raising $75 billion and vaulting itself into the ranks of the world's most valuable companies. The aerospace and artificial intelligence firm sold 555.6 million shares at $135 each, according to a statement posted on its website, achieving a market valuation of $1.77 trillion—or $1.8 trillion when accounting for employee stock options and restricted stock units. The offering dwarfed the previous record holder, Saudi Aramco's 2019 IPO, which raised $29.4 billion. With overallotment options available to underwriters, the total could swell to $86 billion.
The demand was staggering. Retail investors alone submitted orders exceeding $100 billion, far surpassing the roughly 20 percent of shares reserved for them. Overall, the offering drew demand more than four times the available shares. This appetite reflected the outsized influence of Elon Musk's retail following in financial markets—a constituency that has proven willing to bet heavily on his vision, even when that vision extends to space-based data centers and Martian colonies.
For Musk himself, the offering translated into a paper gain of approximately $275 billion. His net worth climbed to roughly $970 billion, according to Bloomberg's Billionaires Index, putting him within striking distance of becoming the world's first trillionaire. His stake in SpaceX, including options, is valued at $688 billion at the IPO price. He retains 84 percent of voting power post-listing and, under SpaceX's governance structure, effectively controls board composition—meaning only he can choose to step down as chief executive.
Yet not everyone celebrated. Veteran short-seller James Chanos dismissed the offering as "a hope and dreams IPO," driven more by enthusiasm for Musk and artificial intelligence than by the company's actual fundamentals. SpaceX has not yet turned a profit. Chanos noted that the company's total addressable market in space is theoretically infinite, allowing investors to construct any narrative they wish—Mars colonies, lunar factories, orbital data centers—to justify the valuation. The company's current plans rest heavily on technology that either does not yet exist or has not been tested at scale.
Yet the skepticism has not dampened broader market appetite. SpaceX represents the first of three major AI-related IPOs expected this year. Anthropic and OpenAI, both competitors in the artificial intelligence space, are anticipated to go public and could each achieve valuations exceeding $1 trillion. The cascade of offerings—combined with Alphabet's recent $85 billion IPO and the possibility that other major tech firms will follow—has sparked debate about whether sufficient investor demand exists to absorb the incoming supply.
SpaceX's pivot from a rocket-launch company to an AI infrastructure giant happened swiftly. In February, Musk's xAI was acquired by SpaceX, lifting the combined company's private valuation to $1.25 trillion. The company has since signed contracts to provide computing infrastructure to Anthropic and Google worth up to $2.17 billion monthly—a figure that could become its largest revenue stream. The timing proved fortuitous, allowing SpaceX to capitalize on surging investor appetite for AI-related bets. Despite recent market volatility, the Nasdaq-100 has climbed 15.45 percent this year, while the Philadelphia Semiconductor Index has soared 81.84 percent.
At the IPO price, SpaceX now ranks among the ten most valuable public companies globally, surpassing Musk's own Tesla. The company's stated ambitions—reaching a $7.5 trillion market capitalization, building space-based data centers capable of delivering 100 terawatts of computing power annually, and establishing a permanent human settlement on Mars with at least one million inhabitants—would unlock additional stock awards for Musk worth up to 1.3 billion shares. Musk cannot sell shares for one year following the listing.
The offering will generate windfalls across a broad spectrum of investors: venture capital firms, special purpose vehicle investors, and members of the Trump administration. Valor Equity Partners, chaired by board member Antonio Gracias, is the second-largest shareholder after Musk with 6.7 percent of Class A shares. SpaceX President Gwynne Shotwell and Chief Financial Officer Bret Johnsen each hold millions of shares and options. More than 1,000 current and former employees have been negotiating with wealth management firms to secure favorable pricing and access to sophisticated financial products with tax advantages ahead of the listing. The question now is whether SpaceX's stock will sustain the enthusiasm that brought it to market, or whether the weight of its own ambitions will eventually test investor patience.

A hope and dreams IPO, driven by enthusiasm for Musk and artificial intelligence rather than the company's actual fundamentals— James Chanos, short-seller and founder of Chanos & Co.

La Conversación del Hearth Otra perspectiva de la historia
What made this IPO different from every other one that came before it?
Scale, primarily. Seventy-five billion dollars is simply unprecedented. But it's also the speed at which SpaceX transformed itself. A year ago it was a rocket company. Now it's an AI infrastructure play. That narrative shift—that's what captured the market's imagination.
The retail investors ordered $100 billion worth of shares. Why would ordinary people bet that heavily on something so speculative?
Musk has built a constituency that believes in him. They've made money following him before. Tesla proved that. And there's something else: they want to own a piece of what they think the future looks like. Space, AI, Mars. It's not purely rational calculation.
But the company hasn't made a profit yet. How do you justify a $1.8 trillion valuation for a company with no earnings?
You don't, if you're being rigorous. That's what Chanos was saying. But the market isn't always rigorous. It prices in potential. And right now, AI potential is the most valuable thing in the world.
Musk controls 84 percent of the voting power. Doesn't that concern investors?
It should, in theory. But it's also why some investors bought in. They're betting on Musk's vision and his ability to execute it. The governance structure guarantees he won't be overruled. For believers, that's a feature, not a bug.
What happens if Anthropic and OpenAI both go public this year at trillion-dollar valuations?
Then we'll know whether this appetite is real or a bubble. Three trillion-dollar AI companies in one year would be extraordinary. It would also test whether there's actually enough capital chasing these bets, or whether the market gets saturated.
