Elon Musk's brief reign as the world's first trillionaire has come to an abrupt end after a sharp pullback in SpaceX shares erased hundreds of billions of dollars in market value and pushed his estimated fortune below the $1 trillion mark.
According to the Bloomberg Billionaires Index, Musk's net worth stood at $957 billion as of June 23, down from a peak of roughly $1.32 trillion reached days after SpaceX's blockbuster public debut. The decline represents an estimated $363 billion reduction in paper wealth, one of the largest short-term reversals ever recorded for an individual investor.
The drop follows an extraordinary surge that began when SpaceX went public on June 12. The company's initial public offering priced 555.6 million shares at $135 each, giving the aerospace giant an opening valuation of approximately $1.77 trillion. Investor enthusiasm quickly drove shares higher, with the stock climbing to a peak near $225.80.
That rally proved short-lived.
By June 23, SpaceX shares had retreated to about $154, a decline of roughly 31% from their post-IPO highs. The stock's reversal triggered a massive decline in the company's overall market capitalization, which fell from more than $3 trillion at its peak to approximately $1.99 trillion.
The scale of the move highlights how closely Musk's fortune is tied to the performance of a single company.
Key figures from the selloff include:
- Peak Musk net worth: approximately $1.32 trillion
- Current Bloomberg estimate: $957 billion
- Wealth decline from peak: about $363 billion
- SpaceX share decline: roughly 31%
- SpaceX market value loss: more than $600 billion
Because Musk owns substantial stakes in SpaceX, changes in the company's valuation have an outsized impact on his estimated wealth. Bloomberg data indicate that nearly 80% of his fortune is linked to SpaceX holdings, making the billionaire particularly vulnerable to swings in the stock price.
The correction also coincided with broader weakness across technology markets. Investors have increasingly questioned lofty valuations tied to artificial intelligence and growth-focused companies, while concerns about interest rates have added pressure to some of the market's biggest winners.
Tesla, another major source of Musk's wealth, also experienced volatility during the period, adding to the downward pressure on his overall net worth.
The reassessment of SpaceX's valuation has also drawn attention to the company's expanding artificial intelligence operations. According to figures cited in the report, SpaceX's xAI division generated $12.7 billion in revenue in 2025 while recording approximately $4.9 billion in expenses. Investors have closely monitored the costs associated with scaling those operations as competition intensifies across the AI sector.
Not all wealth trackers agree on the extent of Musk's decline. While Bloomberg placed his fortune below $1 trillion, Forbes continued to estimate his wealth at roughly $1.1 trillion around the same period. The discrepancy reflects different methodologies for valuing private-company holdings and accounting for liquidity discounts.
