Elon Musk has added approximately $65 billion to his estimated fortune in a single day, putting the billionaire back above the $1 trillion mark after a dramatic rally in his companies’ shares. The surge occurred on October 5, 2026, when SpaceX shares climbed nearly 8% and Tesla stock also gained ground. According to Forbes, Musk’s estimated net worth reached approximately $1.06 trillion, restoring his position as the world’s richest person.
The increase came after SpaceX shares rose following renewed optimism from Wall Street analysts and the company’s recent technological achievements. Morgan Stanley analysts described the stock as undervalued in a note released October 4 and established a $300 price target, approximately 75% above its October 5 closing price. Musk owns approximately 6.42 billion shares of SpaceX, meaning the increase in the company’s stock value significantly boosted his estimated wealth.
The milestone highlights how quickly the fortunes of major technology entrepreneurs can change when their wealth is concentrated in publicly traded companies. Musk’s net worth is largely tied to his ownership stakes in SpaceX and Tesla rather than money held in cash. Although the increase made him a trillionaire again on paper, the value of his fortune remains closely connected to market performance and investor expectations.
SpaceX’s Stock Gains and a Proposed Name Change Draw Attention
SpaceX was the main driver behind Musk’s latest wealth increase, with shares climbing nearly 8% during the October 5 trading session. The rally followed Morgan Stanley’s assessment that the company offered attractive investment opportunities through its space technology, artificial intelligence operations and future projects. The analysts also highlighted potential growth connected to Starship, the company’s ambitious reusable rocket program.
The stock increase came shortly after Musk announced plans to change the company’s name again, this time to SpaceXSI. The proposed name reflects his support for using the term “superintelligence,” or SI, instead of artificial intelligence, or AI. The announcement followed discussions involving technology executives and the White House, where leaders signed a nonbinding agreement related to AI safety and terminology.
The name-change announcement attracted attention, but it was not the only factor behind the stock rally. Morgan Stanley’s investment outlook and renewed enthusiasm surrounding SpaceX’s technological progress were also important. The company’s shares had already recovered substantially from an August low, reflecting investors’ changing expectations about its future business opportunities and valuation.
Tesla’s Performance Also Helped Boost Musk’s Fortune
Tesla also contributed to Musk’s latest increase in estimated wealth as its shares gained following stronger-than-expected third-quarter vehicle deliveries. The company reported sales figures that exceeded analyst expectations, helping improve investor sentiment after a period of uncertainty surrounding its automotive business. Tesla remains a major part of Musk’s financial position, even as SpaceX has become a significant contributor to his fortune.
The gains in both companies helped Musk recover from a substantial decline in his estimated net worth earlier in the year. He first crossed the trillion-dollar threshold in June 2026 following SpaceX’s public listing, but the milestone did not last as shares fell amid concerns about the company’s valuation. By late July, his fortune had dropped sharply from its peak, illustrating the volatility of wealth tied to concentrated stock holdings.
The latest rally reversed part of that decline and returned Musk to trillionaire status, but it does not mean he received $65 billion in cash. His wealth estimate increased because the market value of his shares rose. Selling a large portion of those holdings could also affect their market value, meaning his reported fortune is not equivalent to the amount he could immediately spend.
Musk’s Trillionaire Status Remains Tied to Market Movements
Musk’s return to trillionaire status underscores the extraordinary influence that SpaceX and Tesla have on his estimated wealth. Bloomberg’s Billionaires Index also placed his fortune at approximately $1.04 trillion following the October 5 rally, while Forbes reported an estimate of approximately $1.06 trillion. Differences between the figures reflect the methodologies and timing used by the wealth-ranking organizations rather than a fixed cash balance.
The surge also illustrates the role investor confidence plays in valuing companies connected to emerging technologies. SpaceX’s rocket development, satellite operations and AI ambitions have attracted attention from analysts, while Tesla’s vehicle sales continue to influence its stock performance. However, market expectations can shift quickly, and future gains are not guaranteed.
For now, Musk remains the world’s richest person according to the cited wealth rankings, with his estimated fortune once again exceeding $1 trillion. The latest $65 billion increase was driven primarily by the rising value of his company holdings, not a direct payment. His wealth could continue to fluctuate as SpaceX and Tesla shares respond to business performance, investor sentiment and developments in the technology sector.
