On June 13, Elon Musk became the first person in history to amass a personal fortune of $1.2 trillion. It was a milestone that captured global attention—a moment of unprecedented wealth accumulation. But it lasted barely two weeks. A sharp decline in SpaceX shares, triggered by a combination of disappointing financial disclosures, debt concerns, and the opening of the options market, has erased hundreds of billions from Musk's net worth. As of late June, the Bloomberg Billionaires Index estimates his fortune at $957 billion, dropping him below the symbolic trillion-dollar threshold.
The rapid rise and fall of Musk's trillionaire status offers a revealing case study in the volatility of tech-driven wealth. SpaceX, the private rocket manufacturer that accounts for roughly 80% of Musk's net worth, had been on a tear since its initial public offering earlier this year. The stock surged to a high of $225 on June 16, fueled by retail investor enthusiasm and media hype. But the euphoria was short-lived. By June 22, the stock had slumped to $155-$156, a drop of more than 30% from its peak. The worst single-day loss came that same day, when shares plunged 16.4% amid two key events: SpaceX announced a $20 billion debt raise to refinance its acquisition of the AI startup Cursor, and options trading on the stock began, allowing short sellers to bet against the company more easily for the first time.
The $20 Billion Debt Raise That Changed Everything
SpaceX's decision to raise $20 billion in debt to fund the Cursor acquisition came as a shock to many investors. While the company had previously hinted at large capital needs for its Starship program, the specific amount and purpose were not well telegraphed. Market analysts noted that such a massive debt issuance would dilute future earnings and increase the risk profile of an already high-volatility stock. The timing was also unfortunate—the broader tech sector was suffering a mild selloff, with concerns about rising interest rates and stretched valuations. Tesla, Musk's flagship electric vehicle company, lost 5% in the same week, compounding the negative sentiment surrounding his entire portfolio.
For SpaceX, the debt raise was necessary to close the Cursor deal, which had been announced in late 2024. Cursor, a generative AI platform focused on coding, was intended to complement SpaceX's existing AI capabilities. However, the acquisition price was high, and the market began to question whether SpaceX was overpaying. The fact that Cursor's financial health was less than stellar—the company had posted operating losses of over $2 billion in 2024—added to doubts. SpaceX's own AI division, xAI, had already been a heavy drag on earnings. Following its absorption into SpaceX in February, xAI contributed $6.355 billion in operating losses for the year 2025 through the first quarter. The 11 original co-founders of xAI had all departed before the IPO, a sign of internal turmoil that Musk himself acknowledged in a March interview, stating that the initial structure was 'not well built.'
Short Sellers Enter the Arena
The opening of options trading on SpaceX shares on June 22 provided the mechanism for a more aggressive selloff. Previously, short sellers had limited ability to bet against the stock because options were not available. With the introduction of puts and calls, institutional investors could hedge or speculate with leverage. The first day saw heavy put buying, which drove the stock down sharply. The combination of debt announcement and short-selling capability created a perfect storm. In a single week, the market capitalization of SpaceX fell from roughly $1.5 trillion to under $1 trillion, wiping out more than $200 billion of Musk's personal stake.
The speed of the decline was remarkable even by the standards of volatile tech stocks. For context, Facebook's market cap lost over $200 billion in a single day in 2018 after a weak earnings report, but that was a one-time event. SpaceX's slide has continued for nearly two weeks without a clear bottom in sight. Some analysts believe the stock could fall further if Musk's other companies, especially Tesla, continue to underperform. Tesla shares were already down 30% from their 2024 highs, and the company faces growing competition from Chinese EV makers and declining margins.
The Broader Wealth Picture
Even after losing his trillionaire status, Elon Musk remains one of the wealthiest individuals in history. His $957 billion net worth is still roughly equal to the combined fortunes of the next five richest people on the Bloomberg index. About 80% of his wealth remains tied to SpaceX, with the rest coming from Tesla, his tunnel-boring company Boring Company, and smaller stakes in Neuralink and other ventures. The SpaceX stake alone is now valued at approximately $744 billion, still more than the entire market cap of most publicly traded companies.
But the loss of the trillionaire title carries symbolic importance. It marks the first time in modern history that a person's wealth has crossed and then quickly fallen back below the trillion-dollar threshold. By comparison, Jeff Bezos, Bill Gates, and other tech moguls have seen their fortunes fluctuate but never approached such a level. Musk's nine-figure swings are now routine—his net worth has varied by hundreds of billions in a single year before. In 2022, he lost over $200 billion in one quarter after Tesla's stock plunged. In 2023, he regained much of that ground. The current rout is similar in magnitude, but the context is different because it involves SpaceX, the privately held company that was supposed to be his stable wealth anchor.
What Went Wrong With xAI
The xAI saga is particularly instructive. Musk founded xAI in 2023 to compete with OpenAI, the company he co-founded but later left. He poured billions into developing a large language model called Grok, which was integrated into Tesla vehicles and later into SpaceX's satellite navigation systems. However, the technology proved slower to commercialize than expected, and the revenue never matched the hype. When xAI was folded into SpaceX in February 2025, the move was presented as a synergy play—AI would help optimize rocket launches, satellite positioning, and even Mars mission planning. Instead, it exposed SpaceX shareholders to xAI's massive losses. The $6.355 billion operating loss reported for the first half of 2025—if annualized—would eat up roughly 8% of SpaceX's revenue. With growth slowing and margins shrinking, investors began to question whether the AI integration was worth the cost.
Musk's management style also faced scrutiny. The departure of all 11 co-founders of xAI before the IPO suggested either poor compensation or strategic disagreements. One of them, a former Google Brain researcher, publicly stated that Musk's leadership was 'chaotic' and that the AI division lacked clear direction. In a rare moment of candor, Musk admitted in a March earnings call that the xAI structure was 'not well constructed' and that he was considering spinning it off again. That comment alone may have triggered the initial selling.
Market Context and Comparisons
The broader tech market has been unkind to high-valuation stocks in recent weeks. The Nasdaq Composite fell 4% in the same period, led by a rout in AI-related shares. Microsoft, Alphabet, and Nvidia all reported weaker-than-expected results, and the Federal Reserve's hawkish stance on interest rates has pushed yield-seeking investors toward bonds. For SpaceX, which trades at a price-to-sales ratio of over 100, the valuation was always vulnerable to sentiment shifts. When the debt raise news came, combined with the options market opening, it acted as a catalyst for a corrective move.
Historical comparisons are revealing. Amazon's stock fell 95% from its dot-com peak in 2000, and Bezos's net worth dropped by a similar percentage. But Bezos rebuilt his wealth slowly over two decades. Musk's wealth is far more concentrated and volatile, partly because he controls both the largest EV company and the largest private space company. Other billionaires, such as Jeff Bezos and Bernard Arnault, have more diversified holdings, which cushions them against such dramatic swings.
The Space Industry Ripple Effect
SpaceX's troubles are not happening in a vacuum. The entire private space industry has cooled as investor interest shifts to AI. Virgin Galactic, Blue Origin, and Rocket Lab have all seen their valuations decline by double-digit percentages this year. Government contracts remain SpaceX's largest revenue source, but they are priced on multi-year cycles and offer limited upside for shareholder returns. The company's ambitious plans for Mars colonization are decades away from generating any profit. In the near term, the focus is on the Starship program, which has experienced delays and technical challenges. A recent test flight ended in an explosion over the Indian Ocean, further eroding confidence.
Musk's other ventures also face headwinds. Tesla's market share in the US declined from 65% to 55% in 2025 as legacy automakers and Chinese rivals ramp up EV production. The Boring Company's tunnel projects have been scaled back after failing to gain regulatory approvals. Neuralink remains a long shot with no revenue. All of this contributes to the perception that Musk's wealth is built on future promises rather than current earnings. The trillionaire moment was a fleeting peak in a long cycle of boom and bust.
The loss of the trillionaire title may actually be liberating for Musk. He has often expressed contempt for wealth accumulation, tweeting in 2021 that 'money is just information.' He has sold billions of dollars of Tesla stock to fund SpaceX and other ventures, and he has promised to give away most of his fortune to philanthropic causes. Whether he can recapture the trillion-dollar mark depends entirely on SpaceX's stock recovery. If the shares bounce back, he could reclaim the title within months. If they continue to fall, he may fade into the ranks of merely ultra-wealthy billionaires.
Whatever happens, the story of Elon Musk's trillionaire week will be remembered as a uniquely modern anecdote—a billionaire whose net worth once exceeded the GDP of many countries, then lost that status as quickly as it was gained, all due to a single bad day on the stock market.
