Elon Musk, the boss of Tesla, SpaceX and X, has become the world's first trillionaire. His net worth hit $1.11tn (£828bn) after shares in his rocket company SpaceX soared during its stock market debut on the Nasdaq. The milestone has reignited debate about wealth inequality and Musk's growing influence in global politics, including in the UK.
Musk's trillionaire status is largely tied to his ownership of SpaceX, which went public in June 2026. The company raised $75bn from investors before listing at $135 a share, with the opening trade at $150 and a closing price of about $161. Musk holds a 42% stake in SpaceX, worth $767.1bn at close of trade, plus options. He also owns $168bn in Tesla shares and $116.4bn in Tesla options, according to the Bloomberg rich list. His total net worth makes him the richest person ever by a wide margin.
“Explains how Elon Musk became the world's first trillionaire and what it means for wealth inequality in the UK.”
Musk was born in Pretoria, South Africa, and showed entrepreneurial talent early, selling homemade chocolate eggs and coding a computer game at age 12. He moved to Canada and then the US, studying economics and physics at the University of Pennsylvania. After dropping out of a Stanford physics PhD, he founded two tech startups during the dotcom boom, including a web software firm and an online bank that became PayPal, sold to eBay for $1.5bn in 2002. He used that fortune to found SpaceX, aimed at reducing space travel costs. He also became CEO of Tesla and bought Twitter (now X) in 2022.
His wealth has grown rapidly: he became the first person to exceed $500bn in net worth in October 2025, and a month later Tesla shareholders approved a pay deal that could be worth $1tn. The SpaceX IPO pushed him past the trillion-dollar mark in June 2026.
For UK readers, the significance goes beyond a number. Musk's fortune is roughly equal to the entire economic output of Poland or Switzerland. Critics, including US senators Bernie Sanders and Elizabeth Warren, have called the milestone a 'wake-up call' and argued for wealth taxes. Musk has also become a political figure: he gave hundreds of millions to Donald Trump's re-election campaign, led the Department for Government Efficiency (Doge) in the US, and oversaw drastic cuts including the closure of USAID. In the UK, he has clashed with Prime Minister Sir Keir Starmer over issues including the murder of 18-year-old student Henry Nowak, using his platform X to air his views and influence public debate.
Q: How did Elon Musk become a trillionaire? A: The bulk of his wealth comes from his 42% stake in SpaceX, which went public in June 2026. The company's shares jumped on debut, making his holdings worth $767bn. Combined with his Tesla shares and options, his net worth reached $1.11tn.
Q: Is Elon Musk actually a trillionaire in cash? A: No. His wealth is almost entirely in stock and options. He cannot sell any of his SpaceX shares for at least a year after the IPO, so his fortune is on paper, not liquid cash.
Q: What does Musk's trillionaire status mean for wealth inequality? A: It has intensified calls for higher taxes on the ultra-rich. Musk's wealth is comparable to a country's GDP, while many Americans remain struggling with rising inflation and gas prices. In the UK, his influence on social media and political clashes have raised concerns about the power of concentrated wealth.
What happens next? Musk's SpaceX shares are locked for one year, but his political involvement is likely to continue. In the US, the economy and cost of living are expected to be key issues in the November midterm elections, with many voters feeling pessimistic despite stock-market highs. The broader debate over wealth inequality and the role of billionaires in democracy is unlikely to fade.
