In mid-June 2026, Elon Musk became the world's first trillionaire; by the end of the month, he was no longer one. A brutal global technology stock rout erased billions from his fortune, knocking his net worth back below the $1tn mark less than two weeks after he reached it.
Musk made history on 12 June when his rocket company, SpaceX, debuted on the Nasdaq stock exchange in the largest initial public offering (IPO) ever. Priced at $135 per share, the stock opened at $150 and quickly surged, valuing SpaceX at more than $1.77 trillion. Because Musk owned roughly 42% of the company, the listing instantly propelled his paper fortune past the $1tn threshold. By 16 June, SpaceX shares peaked at $225.64, pushing Musk's total net worth to a high of $1.32 trillion.

But the milestone was short-lived. A widespread tech sell-off triggered by growing doubts over the long-term profitability of artificial intelligence, concerns about capital spending and AI infrastructure costs, and stubborn interest rates hit high-flying technology giants hard. SpaceX shares bore the brunt, plunging more than 30% from their mid-June peak to trade around $156. On a single turbulent Monday, a 16% single-day drop erased an estimated $240 billion from Musk's personal balance sheet. Shares of his electric vehicle venture, Tesla, which he owns about 12% of, slid nearly 6% the next day, compounding the damage.
By the time markets closed on 24 June, Forbes listed Musk's net worth at $970.2bn; Bloomberg's Billionaires Index put it at $957bn. Both figures ended his brief reign as a trillionaire, though he remains the world's richest person by a wide margin. The next wealthiest billionaire, Google co-founder Larry Page, is worth about $284bn, according to Forbes.
Musk's trillionaire status was uniquely vulnerable because his wealth is almost entirely tied to equity in just two companies: SpaceX, which represents nearly 80% of his net worth, and Tesla. Market analysts note that post-IPO volatility is standard for highly valued growth firms, but the scale of the movement reflects a deeper tug-of-war between hype and reality. “For a stock like SpaceX, a lot of decision making might have been emotional,” said Danni Hewson, head of financial analysis at AJ Bell.
For UK readers, the rapid rise and fall of Musk's fortune matters in several ways. First, many British investors may have indirect exposure to SpaceX or Tesla through pension funds, index trackers, or ETFs that hold tech stocks. The volatility underscores the risks of concentrated wealth and the hype surrounding AI and space industries. It also serves as a reminder that paper fortunes can evaporate quickly, and that even the world's richest person is subject to market forces.
Q: How did Elon Musk become a trillionaire? A: He became the first person with a net worth over $1tn on 12 June 2026, after his rocket company SpaceX went public in the largest IPO in history. The stock surged, pushing his fortune to a peak of $1.32tn.
Q: Why did Elon Musk lose his trillionaire status? A: A global technology stock sell-off, driven by doubts over AI profitability and concerns about interest rates, caused SpaceX shares to plummet by over 30% from their peak. Tesla shares also fell, eroding nearly $350bn from his wealth.
Q: Is Elon Musk still the richest person in the world? A: Yes. Despite losing trillionaire status, he remains the world's richest person with a net worth of about $957bn–$970bn. The next wealthiest, Google co-founder Larry Page, is worth around $284bn.
What happens next is uncertain. Musk could regain trillionaire status if either SpaceX or Tesla shares rebound. However, restrictions on insider share sales at SpaceX lift in late July, which could add further volatility. Market conditions and the trajectory of AI investment will be key factors to watch.
