Musk becomes world's first trillionaire as SpaceX IPO soars
Article excerpt
Elon Musk crossed into trillionaire territory on Friday when SpaceX shares jumped nearly 20 percent on their trading debut, following what be the largest initial public offering in history. The aerospace company's explosive market entry added billions to Musk's net worth in a single day, cementing his position as the planet's wealthiest person by a widening margin. SpaceX's valuation reflects both the company's transformation of commercial spaceflight and government contracting over the past decade, and the broader investor appetite for space-industry plays. The IPO caps a remarkable corporate trajectory: SpaceX evolved from a startup few believed in to a company worth hundreds of billions, while remaining under Musk's concentrated control. Musk used the milestone to reiterate his long-standing ambition to establish human settlements on Mars. The offering also triggered strategic ripples across the business world; Friedrich Merz, Germany's likely next chancellor and a Tesla shareholder, sat out the SpaceX IPO, betting instead that Musk will pursue a merger reshaping the electric-vehicle and space industries.

Elon Musk's almost inconceivable fortune has expanded the Overton window of wealth.
Why it matters: Big, round numbers have a remarkable way of focusing minds and setting narratives.
The first trillionaire, much less a trillionaire known for erratic personal behavior, online trolling and support for global right-wing politics, will likely reignite discussion of the diverging fortunes of wage earners and those with market-based wealth, as well as their growing political power.
Driving the news: Shares of Musk's space-launch-satellite services-AI-and-social-media conglomerate SpaceX ended their first day of trading up 19.2%, to $160.95.
At that price, Musk's publicly reported stake of roughly 6.4 billion shares of stock would be worth $1.03 trillion.
Toss that on top of the market value of Musk's $340.141 billion worth of Tesla at Friday's close, and you find yourself at $1.37 trillion.
Context: This is an extreme case of a long-term trend in which those with market-based assets have seen their financial position supercharged, compared with wage-earning workers.
The dynamic has been amplified by the surge in technology shares over the last few years.
Case in point: The gap has swelled between the wealth of the average California household and that of the richest 0.0002% of California households, as spotlighted in a recent paper from the University of California Berkeley economist Gabriel Zucman and his colleagues.
Data: Jasper Boll, Emmanuel Saez, and Gabriel Zucman, "California Billionaires: Wealth, Taxes, and Wealth Tax Revenue Estimates," NBER Working Paper 35218 (2026); Chart: Matt Phillips/Axios
The paper comes out in favor of California's proposed billionaires' tax, noting "the proposed one-off California billionaire tax of 5%, payable over five years, is both small relative to California billionaires' wealth gains and large relative to the taxes they currently pay ... we find that an annual wealth tax on California billionaires could raise substantial additional revenue even after accounting for income tax losses due to mobility."
Yes, but: Musk decamped with his business empire to Texas a couple years back, which will deprive California tax officials of some benefits as of today's IPO. (In the past, IPO booms have created tax windfalls for the state.)
Flashback: Still, if history is any lesson, Musk's gobsmacking net worth could become a potent talking point for advocates of higher taxes on the rich, especially as the U.S. debt load seems increasingly burdensome and the finances of popular programs like Social Security worsen.
In February, Bloomberg's Ben Steverman had a great yarn on how Standard Oil tycoon John D. Rockefeller's emergence as the world's first billionaire came amid a massive political backlash against concentrated wealth that ultimately gave birth to the income tax in 1913 and the estate tax a few years later.
