SpaceX's Historic $1.77 Trillion IPO Puts Elon Musk on Trillionaire Path Amid Tax Debate

SpaceX said it will launch the biggest IPO in history this month, selling 555.6 million shares at $135 each to raise up to $75 billion and value the company at about $1.77 trillion. Elon Musk is not selling any of his shares and will retain roughly 82% of voting power, and major valuations put him on a path to become the world’s first trillionaire. Democrats and progressive figures are using the milestone to argue Musk’s fortune should be taxed more heavily, citing wealth inequality and pointing to government contracting and subsidies. The political debate also draws on longer-running disputes over Musk’s taxes and the role of federal support in his wealth. SpaceX said the IPO is expected to begin trading on Nasdaq on June 12 under the ticker SPCX. Separate estimates emphasize that most of Musk’s wealth is tied up in stock rather than cash, even as it increases his influence across technology and industry.
SpaceX’s targeted $1.77 trillion market value would place it among the very top U.S. companies—only six firms in the S&P 500 are currently worth more, with Nvidia topping the list at about $5.2 trillion.
SpaceX’s anticipated IPO proceeds are expected to far exceed Saudi Aramco’s 2019 IPO, with the estimated fundraising described as “easily” topping the roughly $26 billion raised by Aramco.
One report ties Musk’s wealth trajectory not only to SpaceX but also to Tesla compensation: Tesla shareholders in November 2025 approved a stock-grant package worth up to $1 trillion if Musk hits operational and market-cap targets, including an $8.5 trillion company valuation.
The same report says Musk has defended his fortune through a Mars-colonization narrative—claiming that SpaceX stock bonus conditions include establishing a Martian city of 1 million people—and it contrasts his tax defense (“more than $11 billion in federal taxes” in 2021) with ProPublica’s reporting that he paid no federal income tax in 2018.
A Brookings Institution researcher said the “trillionaire” moment is expected to shape politics beyond the immediate news cycle, warning it will be a key issue in the 2026 and 2028 elections: “This will be an issue in 2026 and 2028.”
