Elon Musk drops from $1tn to $957bn in 13 days as SpaceX, Tesla plunge

New York - Elon Musk lost his trillionaire status on Tuesday, according to data from Bloomberg, with the Bloomberg Billionaires Index valuing his fortune at $957bn on Tuesday.

The key detail is the speed: that $957bn figure marked a drop from the $1.11tn valuation less than 14 days earlier, after Musk became the first person to hit more than $1tn. As of 4pm ET on Wednesday, Forbes listed Musk’s net worth as $970.2bn. In other words, the milestone lasted less than two weeks.

What changed was not some slow-moving, fundamentals-first story. It was a tech rout. Plunging shares in Tesla and SpaceX dragged the tech magnate down to billionaire status. The reversal followed a sharp retreat in SpaceX and Tesla shares as technology stocks broadly tumbled, fuelled by growing doubts over the long-term profitability of artificial intelligence.

That AI-related uncertainty mattered because it landed right on two companies at the center of Musk’s wealth math. Musk reached trillionaire status on 12 June after SpaceX’s historic initial public offering. The rocket, satellite and AI company’s debut on the stock market made Musk the first person with a net worth of more than $1tn, with his fortune hovering around that gigantic figure in the weeks after the IPO.

The IPO itself set the initial conditions for the roller coaster. The blockbuster IPO was priced at $135 per share and opened at $150 when it began trading. That debut valued SpaceX at more than $1.77 trillion. Because Musk owned roughly 42% of SpaceX, the listing instantly propelled his paper fortune past the $1 trillion mark.

From there, investor enthusiasm pushed the stock higher fast. By 16 June, surging interest drove SpaceX shares to a peak of $225.64, pushing Musk's total net worth to a peak of $1.32 trillion. But the market rally did not last. Concerns over capital spending, artificial intelligence infrastructure costs, and stubborn interest rates triggered a widespread tech sell-off, hitting high-flying technology giants such as Nvidia, Intel, and AMD particularly hard.

In that environment, SpaceX took the brunt of the correction. SpaceX shares plunged more than 30% from their mid-June peak to trade around $156. Then the wealth shock accelerated in a very specific way. On a single turbulent Monday, 22 June, a 16% single-day drop erased an estimated $240 billion from Musk's personal balance sheet. The next day, shares of Tesla slid nearly 6%, compounding the damage, with Musk owning about 12% of Tesla's outstanding shares.

This is the part executives and board members should treat as a warning label, not a celebrity news item. Musk's trillionaire status is uniquely vulnerable due to the extreme concentration of his wealth. Unlike traditional billionaires with diversified portfolios, his fortune is almost entirely tied to equity in just two companies: SpaceX, which represents nearly 80% of his total net worth, and Tesla. When the market reprices the growth story, there is no cushion.

There is also a structural lesson for the wider ecosystem of public-market optimism and private-industry fundamentals. Market analysts note that post-IPO volatility is entirely standard for highly valued growth firms. But the scale of the movement here reflects a tug-of-war between hype and reality, with AI expectations under pressure and rates keeping investors picky about future cash flows. For peers, the second-order implication is straightforward: if your company (or a principal investor) is tightly levered to one narrative, one sector, or one multiple, volatility can be less about “noise” and more about how quickly capital markets can change their minds.
