Elon Musk's estimated fortune jumped by about $61 billion on October 2 as SpaceX and Tesla shares climbed, bringing his net worth close to the $1 trillion mark once again.
Musk's Fortune Rises to $979.7 Billion
Elon Musk's estimated net worth reached $979.7 billion at 2:15 p.m. EDT on Friday, October 2, according to Forbes' Real-Time Billionaires list. That represented a one-day increase of approximately $61 billion, or 6.64%.
The sharp increase came as shares of two of Musk's most valuable companies, SpaceX and Tesla, rallied during Friday's trading session.
At that point, Musk was still below the $1 trillion threshold, but the day's gain put his estimated fortune within roughly $20 billion of the milestone.
- One-day wealth increase: About $61 billion
- Estimated net worth: $979.7 billion
- SpaceX share price: About $158.84
- SpaceX daily gain: More than 7%
- Tesla share price: About $371.32
- Tesla daily gain: About 5%
SpaceX Shares Jump After Successful Launches
SpaceX shares rose more than 7% on Friday, trading around $158.84 during the afternoon, after the company completed several successful launches within a 24-hour period.
The movement was particularly significant for Musk's personal wealth because SpaceX represents his largest asset in the Bloomberg Billionaires Index's calculation of his fortune.
SpaceX became publicly traded in June after one of the largest IPOs ever recorded. The company's market valuation and Musk's substantial ownership stake have since become major drivers of changes in his estimated wealth.
Because Musk owns a large stake in SpaceX, even relatively small percentage changes in the company's market value can translate into billions of dollars in changes to his paper wealth.
Tesla Adds Another Boost
Tesla shares also contributed to Friday's increase, rising around 5% to approximately $371.32 during the session.
The move followed Tesla's latest quarterly delivery figures. The electric-car maker delivered 486,532 vehicles in the third quarter of 2026, beating analysts' expectations of about 456,896 vehicles.
Reuters reported that the stronger-than-expected deliveries put Tesla on track to potentially return to annual delivery growth after two consecutive years of declines.
Investors are also continuing to focus on Tesla's longer-term ambitions in artificial intelligence, autonomous driving, robotaxis and humanoid robots, which have become increasingly important to the company's valuation.
Musk's Wealth Has Become Highly Sensitive to Markets
The latest surge illustrates how quickly Musk's estimated fortune can change.
His wealth is largely tied to equity stakes in companies whose valuations can move substantially from one trading session to another. That means a major rise in Tesla or SpaceX can add tens of billions of dollars to his estimated wealth, while a decline can erase a similar amount just as quickly.
Bloomberg's Billionaires Index, for example, listed Musk at $929 billion as of October 1, although different wealth indexes can produce different estimates because they use different methodologies and update times.
Forbes' real-time estimate reached $979.7 billion on October 2 as the two stocks rallied.
A billionaire's estimated net worth is not the same as cash in a bank account. Much of Musk's wealth is represented by ownership stakes in companies, meaning the value can rise or fall with market prices without necessarily creating an equivalent amount of immediately available cash.
Musk Previously Crossed the Trillion-Dollar Mark
The October surge is not Musk's first encounter with the trillion-dollar threshold in 2026.
Forbes reported that Musk became the world's first trillionaire in June after SpaceX began public trading. His estimated fortune later moved below the milestone as SpaceX shares declined and changes involving his Tesla equity affected the calculation.
His fortune subsequently crossed the trillion-dollar level again before falling back below it, demonstrating how closely the milestone is linked to daily movements in his publicly valued assets.
Forbes said Musk's fortune reached a peak of approximately $1.45 trillion in June before falling substantially later in the month.
Why the $1 Trillion Mark Matters
The $1 trillion threshold has become a symbolic measure of Musk's enormous concentration of wealth in publicly and privately valued technology companies.
Crossing the threshold does not mean Musk has $1 trillion in spendable money. Instead, the figure represents an estimate of the market value of his various assets, minus applicable liabilities, using the methodology of the wealth tracker making the calculation.
As a result, the milestone can disappear just as quickly as it is reached when the underlying share prices decline.
SpaceX Is Becoming an Even Bigger Wealth Driver
The public listing of SpaceX has significantly changed the way investors can observe one of the largest components of Musk's fortune.
Before the IPO, SpaceX was privately held, meaning its valuation was based largely on private funding rounds and transactions. Its public listing introduced a continuously changing market price, allowing investors to place a value on the company throughout the trading day.
Bloomberg's wealth methodology identifies SpaceX as Musk's biggest asset, while Tesla remains another major component of his fortune.
This creates an unusual situation in which developments in space launches, satellite services, electric vehicles, artificial intelligence and autonomous technology can all affect the estimated wealth of the same individual.
What Investors Will Watch Next
Attention will remain focused on whether SpaceX can sustain its market valuation following its volatile first months as a public company and whether Tesla can translate stronger quarterly deliveries into sustained annual growth.
Tesla is also preparing to report its third-quarter financial results on October 21, while investors continue to monitor the company's expansion into AI, autonomous vehicles and robotics.
For Musk, every major movement in those companies could continue to have a substantial impact on his estimated personal fortune.
Elon Musk's estimated wealth jumped about $61 billion on October 2 as SpaceX and Tesla shares climbed. Forbes put his fortune at $979.7 billion during Friday afternoon trading, bringing him close to the $1 trillion threshold. The figure remains highly sensitive to movements in the two companies' share prices.
