Musk exits trillionaire club after $63 billion three-day swing

Elon Musk's net worth dropped from a Tuesday peak of $1.05 trillion to $987 billion by Thursday, according to the Bloomberg Billionaires Index. The $63 billion swing erased his return to trillionaire status, regained just this Monday, three days after he first crossed the 13-figure threshold following SpaceX's June IPO.

SpaceX shares fell 3.5% to trade below $162 yesterday. Tesla dropped more than 2% in the same session. Forbes estimated Musk lost $21 billion on Wednesday morning after a report surfaced that SpaceX plans to raise $40 billion to buy Nvidia chips—a move that raised fresh questions about the company's debt load and capital spending on AI infrastructure.

The pullback reversed a Monday rally that lifted Musk's net worth from $976.9 billion to $1.04 trillion in a single session. SpaceX shares had jumped nearly 8% after Morgan Stanley analysts called the stock "cheap" at prevailing prices. Musk holds roughly 4.76 billion SpaceX shares plus 1.3 billion shares of unvested restricted stock—making him uniquely exposed to single-name volatility.

What does Musk himself say about billion-dollar paper swings?

Musk addressed the volatility in an interview with Peter Diamandis earlier this year, recorded about three months before SpaceX's June IPO. He framed his fortune as ownership rather than cash.

"Trillionaire represents some percentage ownership in companies that I built, and it's not sitting in a bank account," Musk said.

He elaborated: "I own a percentage of the companies. The companies are doing lots of useful things, the value of the company grows... and that sums up to that number, which seems high."

How do Musk's peers ride the same roller coaster?

Musk is one of several billionaires whose fortunes swing on equity prices. Oracle founder Larry Ellison briefly dethroned him last September after a breakout earnings report sent Oracle shares up 36%. The 82-year-old, who owns 40% of Oracle, added an estimated $101 billion in a single session—then lost $34 billion of it within two days, even as Musk enjoyed a $35 billion gain that put him back on top.

Michael Dell, who also owns 40% of his namesake tech firm, gained roughly $122 billion between September 2025 and September 2026. Alphabet co-founder Larry Page added $16.3 billion in the same span. Jeff Bezos gained $24.5 billion.

Bridgewater Associates founder Ray Dalio has framed the same distinction Musk made.

"Wealth is not the same as money," Dalio said on Steven Bartlett's The Diary of a CEO podcast. "You see a lot of people getting wealthy but you can't spend the wealth. You have to sell the wealth to get money because you can only spend money."

What does Musk predict for the next decade?

In an interview with The Economist, Musk said "money won't matter in 2036." His reasoning: AI will absorb so much human labor that jobs become voluntary, and cash itself loses relevance. Back in 2024, Musk proposed "universal high income" to distribute money in a non-working world.

He returned to the theme in his Diamandis appearance, citing Iain M. Banks' Culture novels, which portray a civilization of intelligent robots with no traditional employment.

"In those books, money doesn't exist. It's kind of interesting," Musk said. "And my guess is, if you go out long enough—assuming there's a continued improvement in AI and robotics, which seems likely—money will stop being relevant."

Whether AI delivers that future or not, Musk's near-trillionaire status will remain hostage to the next SpaceX earnings call and the next chip-deal headline.
