Correction, 6 Nov 2026: an earlier version linked our close piece as a $1.44 trillion loss; on Nasdaq’s official closes the 12-stock basket lost $1.447 trillion, which rounds to $1.45 trillion.
Nvidia chief executive Jensen Huang’s net worth fell $15.1 billion to $150.9 billion on 5 November, dropping him from ninth to 13th on the Bloomberg Billionaires Index, Bloomberg reported. The 500 people on the index lost a combined $185 billion that day, “the 14th-biggest one-day rout since Bloomberg began its ranking in 2012”, according to the report.
Elon Musk lost $79.7 billion and Oracle co-founder Larry Ellison $10.1 billion, Bloomberg said. Together with Huang that is $104.9 billion, about 57% of the day’s $185 billion, by our arithmetic.
Business Pill · Concentration
An evergreen Business Engineer explainer on concentration. It teaches the general idea only and does not discuss this selloff or the Bloomberg index.
The key insight: As we read it, the 5 November selloff hit these AI-linked fortunes heavily: of the $185 billion the 500 people on the Bloomberg Billionaires Index lost, Musk, Huang and Ellison accounted for $104.9 billion, about 57%, by our arithmetic on Bloomberg’s figures. Huang’s $15.1 billion loss, which moved him from ninth to 13th, is reproduced at about $15.04 billion by his Form 4 share count times Nvidia’s fall at the close.
Bloomberg tied the drop to “expectations that a Democrat-controlled House and Senate will work to constrain construction of data centres”, which it said helped drive shares of semiconductor makers and suppliers of computing power lower. It reported that Nvidia fell 9.3%, the most since January 2025, SpaceX 9% and Oracle 6.9%.
The report said all three men, “especially Huang”, are heavily exposed to the build-out of data centres for artificial intelligence. It added that tech billionaires had been on track for their best year ever, accounting for 36% of the index’s total wealth (the report as syndicated by The Straits Times).
Huang’s Form 4 filed on 18 September lists 811,521,160 Nvidia shares held directly and through trusts and limited liability companies. Nvidia closed at $181.60 on 5 November against $200.13 a day earlier, according to Nasdaq’s historical quotes, a fall of $18.53 a share, or 9.26%.
Those shares times that fall come to about $15.04 billion, by our arithmetic, close to Bloomberg’s $15.1 billion. The filing is from September, so later changes in his holdings would not be included, and the Form 4 count is not the same as Bloomberg’s full net-worth estimate.
Reading the Numbers
Musk alone accounted for about 43% of the day’s $185 billion, by our arithmetic; the other 497 people on the index lost about $80.1 billion between them. Huang’s $15.1 billion was about 9.1% of the $166.0 billion he had before the drop (our arithmetic on Bloomberg’s figures).
As we read the shares, Musk alone accounted for about 43% of the day’s losses, more than Huang and Ellison combined, by our arithmetic.
As we read the check, the Form 4 count and Nasdaq’s closes land within about $0.06 billion of Bloomberg’s figure for Huang, though the filing dates from September and Bloomberg’s estimate covers more than listed shares.
As we read the context, Bloomberg says tech billionaires had been on track for their best year ever, at 36% of the index’s wealth, which is why a one-day data-centre selloff shows up so directly in the ranking.

“the 14th-biggest one-day rout since Bloomberg began its ranking in 2012”
Three Implications
FOR THE RANKING Bloomberg reports that Huang moved from ninth to 13th on the index after a $15.1 billion fall to $150.9 billion.
FOR THE AI BUILD-OUT Bloomberg links the losses to expectations that Congress will work to constrain data-centre construction; that link is its reading.
FOR READING THE FIGURES They are index estimates that move with share prices; we checked only Huang’s against filings and the close.
The framework says: “The diagonals where dominance concentrates are where the supercycle’s profit pools live.”
As we read it, the 5 November losses landed on the fortunes tied most closely to those concentrated positions in chips, compute and AI infrastructure. The framework does not discuss this selloff or the Bloomberg index.
What Is Not Established
Bloomberg’s figures are estimates from its index and change with share prices; we have not independently checked Musk’s or Ellison’s numbers. The report as we read it names only these three losses and gives no figures for other technology founders. Its link between the election result and the selloff is Bloomberg’s reading. Nvidia’s 9.26% fall here uses Nasdaq’s official close.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
The 500 richest people lost $185 billion on 5 November, Bloomberg reported, and Huang fell from ninth to 13th after losing $15.1 billion, a figure his Form 4 holdings and Nasdaq’s close reproduce at about $15.04 billion by our arithmetic. Musk, Huang and Ellison together accounted for about 57% of the day’s losses.
A note on sourcing. The net-worth figures, the index ranking and the $185 billion total are from Bloomberg’s report of 5 November 2026 on the Bloomberg Billionaires Index, read in the text syndicated by The Straits Times. Huang’s share count is from his Form 4 filed with the SEC on 18 September 2026, and Nvidia’s closing prices are from Nasdaq’s historical quotes. The share-based check, the shares of the total and the other ratios are our arithmetic.
