Elon Musk has cemented his status as the world’s wealthiest person by a staggering margin, with his net worth climbing to an estimated $1.3 trillion on Monday after shares of SpaceX surged 20 percent on their second day of trading on the Nasdaq stock exchange.

The extraordinary wealth jump estimated at approximately $135 billion in a single day was driven almost entirely by the meteoric rise in SpaceX stock, which closed at $192 per share on Monday after finishing its first trading day at $160.

The surge pushed SpaceX’s total market capitalisation to approximately $2.52 trillion, up from the $1.77 trillion valuation at which the company priced its initial public offering just days earlier. The IPO, which priced at $135 per share and raised $75 billion, was already the largest in history, surpassing the $25.6 billion raised by Saudi Aramco in 2019.

Musk, who owns approximately 43 percent of SpaceX, became the world’s first trillionaire when the company went public on June 12, 2026, under the ticker symbol SPCX. At the IPO price, his SpaceX stake alone was valued at around $866 billion. Combined with his other assets including his stake in Tesla, xAI, and other holdings estimated at around $260 billion his total fortune crossed $1 trillion for the first time in recorded history. Monday’s 20 percent rally in SpaceX shares pushed that figure sharply higher still, landing his net worth at approximately $1.3 trillion according to estimates by CelebrityNetWorth.

The scale of Musk’s wealth is difficult to comprehend. His fortune is now nearly four times the size of the next-richest person on Earth, Google co-founder Larry Page, whose net worth stands at approximately $292 billion.

His wealth also exceeds the combined fortunes of Page, Sergey Brin, and Jeff Bezos combined. SpaceX, which in February 2026 completed its acquisition of xAI which itself owned X, formerly Twitter has emerged as the single most powerful driver of Musk’s wealth, with the Starlink satellite network and the promise of space-based AI data infrastructure underpinning investor enthusiasm for the newly listed company.

The landmark figures have reignited global debate about the concentration of extreme wealth, with economists and critics noting that the world’s ten richest people now collectively hold approximately $3 trillion, with Musk alone accounting for more than a third of that total.
