Elon Musk is a trillionaire again after SpaceX and Tesla shares added $62 billion to his fortune in a single day

Elon Musk is a trillionaire again. He regained the status on Monday as rallying shares of SpaceX and Tesla added more than $62 billion to his net worth in a single trading session, less than a week after he fell below the trillion-dollar threshold for the first time since briefly becoming the first person in history to cross it.

Shares of SpaceX jumped 7.6 percent and Tesla surged 8.6 percent as of Monday afternoon, pushing Musk's fortune back above $1 trillion. The swing capped a wild fortnight for the world's richest person, whose net worth has now crossed the trillion-dollar line, fallen below it, and crossed it again, all within the span of about two weeks.

Musk holds 4.8 billion shares of SpaceX and another 350 million stock options with an exercise price of $8.40 per share. Earlier this month, he disclosed holding approximately 700 million Tesla shares. He remains the world's richest person by a wide margin, ranking well ahead of Google co-founders Larry Page, worth $288.7 billion, and Sergey Brin, worth $266.3 billion. Even with Monday's surge, his fortune remains well below the $1.45 trillion peak it briefly touched on June 16, the high-water mark reached in the immediate euphoria following SpaceX's stock market debut.

Musk became the world's first trillionaire when SpaceX's record-setting initial public offering on June 12 boosted his net worth to approximately $1.1 trillion. The milestone was the latest in a string of wealth thresholds he has crossed in rapid succession. He became the first person worth $400 billion in December 2024, then crossed $500 billion, $600 billion, $700 billion, $800 billion and $900 billion in succession through early 2026 before the SpaceX listing pushed him past the trillion mark entirely.

The trillion-dollar status did not last. SpaceX shares pulled back sharply from their post-IPO highs amid a broader technology sector selloff and investor unease over a $20 billion bond issuance the company launched just ten days after completing its IPO, a move that rattled markets already digesting the largest stock debut in history. New restrictions on $116 billion of Musk's Tesla shares compounded the decline, and by late June his net worth had fallen to approximately $946 billion according to the Bloomberg Billionaires Index and $951 billion according to Forbes, briefly ending his run as a trillionaire roughly a week after it began.

Monday's rebound restored the title, though the underlying volatility tells its own story about what it means to hold the world's largest fortune when the bulk of it sits in two newly public or recently re-rated stocks. SpaceX's valuation, which exceeded $2.7 trillion at its post-IPO peak before falling and now rebounding again, has become one of the most closely watched and most disputed numbers in global markets. Morningstar's fair value estimate for the stock sits at roughly $63 per share, a fraction of where it has traded since listing, while bullish analysts including those at ARK Invest argue the company could be worth $3.1 trillion by 2030. The gap between those estimates is the entire explanation for why Musk's fortune has swung by hundreds of billions of dollars in a matter of days.

Tesla's compensation structure adds a second layer of volatility to Musk's wealth. He does not draw a salary from the company. Instead, a 2018 pay package tied his personal earnings entirely to Tesla's market valuation and revenue milestones, an arrangement shareholders re-ratified in 2024 after a Delaware judge initially rescinded it, only for the Delaware Supreme Court to restore the package in December 2025. Tesla shareholders separately approved a new compensation plan in November that could, on its own, be worth close to $1 trillion if the company hits a series of ambitious targets over the next decade.

For now, the man whose fortune briefly touched $1.45 trillion, fell to $946 billion, and has now bounced back above $1 trillion in the space of two and a half weeks remains nearly four times wealthier than the next richest person on the planet. Whether the trillionaire status proves durable or simply marks the latest swing in what has become the most volatile great fortune in modern history is a question the market will keep answering one trading session at a time.
