What Elon Musk's New Trillionaire Status Means for Society

Elon Musk became the world’s first trillionaire on June 12 after SpaceX went public, raising his net worth past $1 trillion, renewing discourse in Washington, D.C. over taxing the wealthy.

SpaceX shares opened at $150, closing at $160.95 on their first day of trading, a gain of up to 19%. The IPO raised $75 billion, valuing SpaceX at around $1.8 trillion. Musk’s holdings in SpaceX and Tesla pushed his fortune to approximately $1.1 trillion, according to Forbes estimates.

The milestone prompted responses from Democratic lawmakers. Senator Elizabeth Warren of Massachusetts wrote on social platform X that the typical American household would need to work for 11 million years to accumulate Musk’s wealth. Warren reiterated the need to tax the ultra-wealthy. Senator Bernie Sanders of Vermont said Musk’s payments into Social Security match that of someone earning $184,500 a year.

Representative Ro Khanna, D-Calif., has proposed legislation that would tax the nation’s 938 billionaires. Khanna’s office has estimated that this bill could raise more than $4 trillion over 10 years.

California voters could contribute to the debate this fall. A potential ballot measure would implement a 5% tax on residents with net worths reaching past $1 billion. Although Musk, who lives in Texas, would not be subject to that tax, his wealth could raise awareness for other billionaires who may have to pay. Not all reactions have been critical of the trillionaire. Many conservatives view Musk’s wealth as a display of American entrepreneurship rather than a systemic failure. Many use this perspective to argue that taxing the rich more heavily would discourage the risk-taking business ideas that led Tesla and SpaceX to be created in the first place.

An estimated 4,400 former and current SpaceX workers are expected to become millionaires through compensation from stock tied to their initial public offering.

A large amount of Musk’s wealth is unrealized, tied in stock he has not sold. Unrealized stock gains do not get taxed under U.S. law until the shares are sold. Critics have noted that Musk did not pay any federal income tax in 2018; between 2014 and 2018, he had an effective tax rate of roughly 3.27%.

Musk’s wealth has sparked debate as the 2026 midterm elections are imminent. Both political parties are expected to use Musk’s wealth to support their arguments on tax policy.
