Elon Musk is on track to become the world's first trillionaire when SpaceX makes its Wall Street debut on Friday, a milestone that is hard to describe without sounding absurd.
Before SpaceX announced its record-setting initial public offering on Thursday, Musk was already the richest person on the planet, with an estimated fortune of about $696 billion, according to the Bloomberg Billionaires Index. His 42 percent stake in the rocket-and-AI company could push him into financial territory no private individual has reached before.
How SpaceX's Nasdaq debut changes the numbers
SpaceX is set to begin trading on the Nasdaq stock exchange at a valuation of $1.77 trillion. The company is selling 555.6 million shares at $135 each.
Estimates for Musk's stake range from $743 billion to $866.5 billion. If trading goes as expected, the Tesla chief executive would cross the trillion-dollar threshold before markets close on Friday.
For perspective, $1 trillion is not just “very rich” with extra zeros attached. Oxfam, the United Kingdom charity, has noted that spending $1 million every day would still take 2,740 years to get through $1 trillion. Thankfully, no one is asking the rest of us to test that timeline.
Musk's lead over other billionaires would also become unusually wide. Bloomberg lists Google co-founder Larry Page as the world's second-richest person, with a fortune of $304 billion. Musk would be more than three times richer.
How Musk compares with America's old tycoons
Comparing fortunes across centuries gets messy fast because prices, wages and living standards change. Still, economists often use a person's share of national output as one rough measure.
John Jacob Astor, widely regarded as the first American multimillionaire, was worth between $20 million and $30 million when he died in 1848. That was roughly 1 percent of United States gross domestic product, according to the MeasuringWorth Foundation, a nonprofit used by economic historians.
Steel magnate Andrew Carnegie later built a fortune of about $380 million, equivalent to roughly 0.5 percent of U.S. GDP when he died in 1919. Oil tycoon John D. Rockefeller was worth about $1.4 billion at his death in 1937, or around 1.5 percent of U.S. GDP.
A trillion-dollar Musk fortune would be worth about 3 percent of U.S. GDP. By that measure, his wealth would exceed the relative economic weight of the best-known industrial magnates of the 19th and early 20th centuries.
What historians say about extreme wealth
Guido Alfani, a professor of economic history at Bocconi University in Milan, offered another comparison: how much human labor a fortune could buy.
“If we do this, we can surely conclude that Elon Musk might be the wealthiest person who has ever lived – excluding emperors or other rulers whose wealth is not easily distinguishable from that of the state,” Alfani told Al Jazeera.
Alfani estimated that Musk could command the labor of 557,800 people in 2025. Rockefeller, by contrast, could command the work of about 116,000 people in 1937, while Carnegie could command about 48,000 in 1901.
Musk is a deeply polarizing figure, but that is not new in the history of extreme wealth. The tycoons of the Gilded Age were also controversial in their own time, often admired for their money and disliked for how they made and protected it.
Why the Gilded Age comparison cuts both ways
Astor became known as one of New York City's largest and most criticized landlords. Carnegie, Rockefeller and their peers were branded “Robber Barons” because of ruthless and anti-competitive business tactics.
Richard White, professor of history emeritus at Stanford University, said the industrialists were rich beyond anything Americans had seen before.
“What made them famous was that they were very good at making and keeping money. There is little sign they accomplished much else,” White told Al Jazeera.
“Some admired them for their wealth. Most of their contemporaries despised them.”
White also said figures such as Rockefeller understood that their fortunes depended partly on shaping government policy.
“All intervened in politics,” he said.
“All this involved a degree, in the Gilded Age, a very high degree, of corruption.”
Musk has also moved forcefully into politics. He aligned himself with Donald Trump's 2024 presidential campaign and later led the Trump administration's controversial effort to cut waste and fraud in the federal government.
How Musk uses money, politics and platforms
Since his $40 billion hostile takeover of Twitter in 2022, Musk has used the platform, now called X, as a personal broadcast system. He has promoted right-wing views on divisive issues including immigration and transgender rights.
That public reach makes his wealth feel less abstract to audiences. This is not only a balance-sheet story. It is also about how one person's money can shape political debate, media attention and the daily information diet of millions of users who did not exactly vote on the matter.
Musk also differs from earlier tycoons in one major area: public philanthropy. The Gilded Age magnates built hospitals, libraries, universities and museums, and they funded campaigns against diseases such as hookworm and yellow fever.
“When examining the Robber Barons of the Gilded Age and Progressive Era, despite their many failings, they were also among the pioneers of modern large-scale philanthropy,” Christopher Nichols, a professor of history at Ohio State University, told Al Jazeera.
Where Musk stands on philanthropy
Carnegie famously gave away 90 percent of his wealth during the final two decades of his life. MeasuringWorth estimates that sum would be worth at least $42 billion in today's money.
Nichols pointed to Carnegie's 1889 essay “Gospel of Wealth,” which argued that the rich should use their fortunes for the public good during their lifetimes rather than simply pass them to heirs.
In 2010, Microsoft founder Bill Gates and investor Warren Buffett created the Giving Pledge, which asks the world's richest people to donate most of their wealth during their lives or in their wills. Musk joined in 2012.
Much of Musk's giving has flowed through the Musk Foundation to causes that overlap with his businesses, according to the Capital Research Centre, a U.S.-based think tank that tracks nonprofit spending.
Billionaire investor Peter Thiel, who co-founded PayPal with Musk, said in a closed-door lecture last year that he had urged Musk to walk away from the pledge because the money would go to “left-wing nonprofits.” Musk has not publicly withdrawn, but Thiel said Musk took the advice seriously.
Why the political backlash has been different
Musk has also favored donor-advised funds, including Vanguard Charitable and Fidelity Charitable. He gave $37 million to Vanguard Charitable in 2017 and $39 million to Fidelity Charitable between 2018 and 2020, according to the Capital Research Centre.
One big difference between Musk and the industrial barons is that his fortune has not yet triggered political or social change on the scale seen in the Gilded Age.
That earlier era saw major labor unrest and social activism. It eventually helped produce landmark antitrust regulation, the Federal Trade Commission and a federal income tax.
Joshua Rosenbloom, a professor of economics at Iowa State University, said today's political and economic system is more resistant to change than the “far more fluid” order that existed from the 1870s to the late 1920s.
“Rockefeller and Carnegie exercised considerable power in their time, and Musk’s influence is not wildly different from theirs,” Rosenbloom told Al Jazeera.
“My sense is that at the turn of the 20th century, the rise of large concentrations of wealth was politically controversial, and perhaps more so than is true today,” he said.
“The 1890s and early twentieth century were marked by more visible labor protest and political violence than we see today.”
Why a trillion-dollar fortune can still shrink
Daniel Waldenström, a professor of economics at the Research Institute of Industrial Economics in Stockholm, said Musk may well be the richest person who has ever lived. But market wealth is not permanent.
“He faces competition and the market valuation of his corporations can change,” Waldenström told Al Jazeera.
“It may well be that some of Musk’s assets will lose value if reality changes,” he said.
That has happened before. In 2022, amid the inflation boom, Tesla lost more than 60 percent of its market value.
For now, though, the SpaceX listing is set to turn a long-running debate about wealth, power and public responsibility into a much larger one. The number is new. The argument isn’t.
