Elon Musk Becomes First Trillionaire; Lawmakers Seek Wealth Tax

On June 12, Elon Musk’s net worth reached roughly $1.1 trillion after SpaceX raised $75 billion in an initial public offering on the Nasdaq. The increase followed primary and secondary share sales tied to the offering.

Musk’s fortune now exceeds the combined wealth of Larry Page, Sergey Brin, Jeff Bezos and Larry Ellison. The 10 richest billionaires hold about $3.1 trillion in total, and billionaires gained roughly $68.2 billion in a single day after the offering. Data used in public measures of inequality show a very large percentage gap between the average billionaire and the average American.

International measures of wealth distribution show concentration at the top. The World Inequality Report estimates the richest 10% own about 75% of global wealth while the bottom half holds roughly 2%. A separate analysis in January found the 12 richest billionaires hold more wealth than the poorest half of the world’s population. The World Inequality Report also reports fewer than 60,000 multi-millionaires control about three times the wealth of half of humanity.

Household finances are under pressure as prices rise. U.S. consumer prices increased 4.2% in May. Since February 28, U.S. households have spent an estimated $57.7 billion more on gasoline and diesel, about $440.60 per household, and national gas prices were tracked at about $4.10 a gallon.

Several lawmakers responded to Musk’s net worth milestone with proposals for new taxes. Senator Elizabeth Warren wrote that the typical American household would need to work more than 11 million years to reach Musk’s level of wealth and called for a wealth tax. Senator Bernie Sanders tweeted that Musk “pays the same amount into Social Security as someone making $184,500” and urged lifting the payroll tax cap to make Social Security solvent for 75 years and expand benefits by $2,400. Representative Pramila Jayapal and other progressive lawmakers backed similar proposals.

Legislative options under consideration include an annual levy on net worth and raising or removing the payroll tax cap. Supporters propose using new revenue to expand Social Security and other programs. Opponents raise concerns about potential effects on investment and the broader economy.

In the U.S., the top 1% holds about 31% of wealth while the bottom 50% hold approximately 2.6%, according to available wealth-distribution estimates. Lawmakers and legal experts have noted practical and legal challenges to implementing a recurring wealth tax, and debates over specific proposals are expected to continue in Congress.
