Elon Musk has become the world’s first trillionaire after shares of his aerospace and technology company, SpaceX, surged following a historic stock market debut.

The milestone came after SpaceX began trading on the Nasdaq exchange in what has been described as the largest stock market debut in history. Strong investor demand pushed the company’s valuation to approximately $2.2 trillion, significantly boosting Musk’s personal fortune.

According to the Bloomberg Billionaires Index, Musk’s net worth reached an estimated $1.11 trillion (£828 billion), further extending his lead as the wealthiest person in the world.

SpaceX offered its shares at $135 each during the initial public offering (IPO). However, investor enthusiasm quickly drove the stock price higher, with shares opening at $150 and briefly climbing to $176.50 before settling at around $161 by the end of trading.

The IPO raised approximately $75 billion from investors, highlighting strong confidence in SpaceX’s future growth prospects. The company has become a major player in space exploration, satellite communications, and artificial intelligence-related technologies, sectors that continue to attract significant market interest.

Musk remains the controlling shareholder of SpaceX, holding an estimated 42% ownership stake. His position gives him substantial influence over the company’s strategic direction and future investments.

Bloomberg estimates that Musk’s SpaceX holdings alone are worth more than $767 billion, with additional stock options valued at nearly $54 billion. Beyond SpaceX, Musk also maintains a significant stake in electric vehicle manufacturer Tesla, with shares and options collectively worth hundreds of billions of dollars.

The achievement marks a historic moment in global wealth creation, making Musk the first individual to surpass the $1 trillion net worth threshold.

Investors continue to view SpaceX as one of the most influential technology companies of the future, driven by its ambitions in commercial space travel, satellite internet services, and advanced artificial intelligence initiatives.

The company’s successful market debut is expected to further strengthen its ability to invest in large-scale projects while reinforcing Musk’s position as one of the most powerful figures in the global technology industry.
