From Record IPO to Trillionaire Status: The Aftermath of SpaceX's Nasdaq Debut

When SpaceX rang the opening bell on the Nasdaq on June 12, 2026, it didn't just launch the largest initial public offering in history. It triggered a financial chain reaction that turned its founder into the world’s first trillionaire, eclipsed the market cap of the largest cryptocurrency, and reignited a national political firestorm over wealth inequality. The days that followed rewrote record books and sharpened the divide over how, and whether, to tax wealth that exists largely on paper.

A Record-Shattering Market Debut

SpaceX, trading under the ticker SPCX, priced its IPO at $135 per share, raising a staggering $75 billion and securing an initial valuation of approximately $1.77 trillion . This dwarfed the previous record of $29.4 billion set by Saudi Aramco in 2019 .

The market's appetite was immediately clear. SPCX opened at $150 per share — an 11% jump from its listing price — and closed its first day at $160.95, a 19.2% gain that pushed the company’s market capitalization to about $2.1 trillion . First-day trading volume was enormous, topping $85 billion .

The rally had just begun. By Monday, June 15, shares surged another 20% to close at $192.50 . On June 16, the stock climbed as high as $225.84 intraday, pushing SpaceX’s market cap to roughly $2.8 trillion and triggering a cascade of fresh milestones .

Musk’s Wealth: Surpassing Bitcoin’s Entire Market Cap

Elon Musk’s personal fortune, anchored by his massive stake in SpaceX, grew in lockstep with the stock. Company documents revealed he owned approximately 42% of SpaceX prior to the offering, a holding estimated at about $765 billion on IPO day . Combined with his stakes in Tesla, Neuralink, and other ventures, Forbes and Bloomberg estimated his net worth crossed the $1.1 trillion mark on June 12, making him the first person in modern history to achieve trillionaire status .

But the headline-grabbing moment came days later. As SpaceX’s stock continued its torrid climb, Musk’s net worth rose to approximately $1.32 trillion to $1.4 trillion by June 16–17, exceeding the total market capitalization of Bitcoin, which stood at about $1.29 trillion to $1.31 trillion at the time . For context, his personal paper wealth not only topped Bitcoin but was also larger than the combined market cap of all other cryptocurrencies, a cohort that had declined roughly 50% from its peak .

This milestone came just months after Bitcoin itself had reached a peak market cap near $2.5 trillion in October 2025, underscoring the extraordinary speed with which the SpaceX IPO concentrated value in one individual’s hands .

SpaceX Overtakes Amazon in Global Rankings

The stock surge propelled SpaceX past several tech giants. By its second day of full trading, it had surpassed Broadcom, Meta Platforms, and Tesla to become the sixth most valuable U.S.-listed company .

On June 16, the rally pushed SpaceX’s valuation definitively past Amazon’s $2.65 trillion market cap, making it the world’s fifth most valuable publicly traded company . During intraday highs, SpaceX’s value reached approximately $2.89 trillion to $2.97 trillion, at one point even briefly eclipsing Microsoft to become the fourth largest company by market cap, before settling back around $2.65 trillion at the close .

The ranking behind SpaceX included Nvidia ($5.09 trillion), Alphabet ($4.46 trillion), Apple ($4.34 trillion), and Microsoft ($2.92 trillion), according to CNBC data as of that evening . This was all the more remarkable because SpaceX posted a net loss of $4.9 billion on $18.7 billion in revenue in its prior fiscal year, compared to Amazon’s $78 billion profit on $717 billion in sales . The market was pricing in Musk’s sprawling ambitions in AI, satellites, and space infrastructure far more than current financials.

The Political Debate Over Wealth Taxes Reignites

The spectacle of one person holding more wealth than the entire cryptocurrency market or the market value of Amazon did not go unnoticed in Washington. Within hours of SpaceX’s debut, progressive politicians began using the milestone to renew calls for taxing extreme wealth.

Senator Elizabeth Warren posted on X on IPO day that “the typical American household would have to work more than 11 million years to make Elon Musk’s level of wealth,” explicitly calling for a wealth tax . New York City Mayor Zohran Mamdani used Musk’s own platform, X, to demand policymakers “tax the rich,” drawing a sharp contrast between the IPO’s winners and the city’s working-class struggles .

The political response intensified over the following days as Musk’s net worth climbed past Bitcoin’s market cap, with the clash focusing on whether to tax unrealized capital gains — the very mechanism that created Musk’s trillionaire status without him selling a single share . The debate extended to state-level politics. California voters faced a November ballot measure to impose a one-time 5% wealth tax on billionaires, and Massachusetts lawmakers advanced their own proposals, according to The Boston Globe .

Musk had already addressed the wealth tax conversation months earlier, arguing on X that a tax on billionaires would eventually expand to everyone — drawing a parallel to the federal income tax, which he noted was enacted as a temporary measure on the top 1% during World War I . The IPO gave that argument new urgency among his supporters and fresh ammunition to his critics, cementing the event as a defining moment in the long-running American tax debate.
