Three men lost $105 billion in a single session, yet not one law changed in Washington — the thing that moved the market was decided at the ballot box, not Congress. On Thursday, November 6, 2025, Jensen Huang of Nvidia, Elon Musk of SpaceX, and Larry Ellison of Oracle collectively lost $104.9 billion in a single trading session, more than the GDP of many countries, after the November 3 midterms delivered a sweeping Democratic win.
Investors feared Democratic control of Congress could restrict data-center construction and slow demand for Nvidia's chips and infrastructure, sending the Nasdaq Composite down 5.52% to 24,315 — its biggest one-day decline in 19 months — and the S&P 500 down 4.36% to 7,353.73. For an everyday investor holding index funds, the story is not the billionaire number but the one-day stress test, and whether the AI spending boom that drove record highs can continue at the same pace.
What the Session Actually Cost
The numbers are staggering. Market-value loss estimates differ by source: about $2.5 trillion (CNN), over $3 trillion in the S&P 500 (Moneycontrol), and about $3.2 trillion in US stock market value (FT).
The Dow Jones Industrial Average fell 3.44% to 51,523.06, a broad reversal of Wednesday's post-election rally.
Nvidia fell 9.3%, its steepest decline since January 2025. The Magnificent Seven lost as much as $1 trillion in market value.
Why the Machines Fell
The selloff was driven by fears that Democratic control of Congress could restrict data-center construction, slowing demand for Nvidia's chips, servers and other infrastructure. Democratic wins in states where opposition to new data centers has grown sharpened those worries.
What it means for the reader: A diversified index fund fell with the market because technology is its largest weight.
A house and Social Security did not move. The selloff was one session. The open question is whether the AI spending boom that drove record highs can continue at the same pace.
The Part the Billionaire Number Hides
The billionaire number hides the broader selloff. Bloomberg's 500 billionaires lost $185bn, the 14th-largest one-day drop since the index launched in 2012. Investors feared a potential slowdown in AI-related investments.
What it means for the reader: The selloff was not limited to the three executives. It reached semiconductor manufacturers, companies financing and operating data centers, and even electricity suppliers like GE Vernova and Constellation Energy. When demand for electricity is tied to the next wave of data centers, a pause in that build-out reaches past the chipmakers into the power grid itself.
Where the Safe Money Went
The one-day selloff in technology stocks was a test of what counts as a safe place to hold money. When concentrated technology bets reprice in a single session, the ballast in a portfolio is the part that does not depend on the next data center being built.
What it means for the reader: For a retiree watching this session, the lesson sits in the structure of the holdings, not the headline wealth figure. The assets that do not depend on AI infrastructure build-out sit outside the technology reassessment, moving on a different schedule rather than in a single volatile session.
A fund tied heavily to a handful of technology names carries the swings of those names. The part of a portfolio that moves on its own schedule is what steadies the whole on a day like Thursday.
Why One Day Is Not Yet a Trend
The trigger was a political shift and concerns about the pace of AI infrastructure investment, not a change in law. Neither Senator-elect's proposal for a pause nor a state moratorium has been enacted nationwide.
A single session does not settle the question. Markets repriced on fear of what control of Congress might bring, well before any bill is written, debated or signed. The gap between what investors expect and what lawmakers actually pass can be wide, and it often closes slowly.
The one thing that matters most is watching whether the technology reassessment continues or Thursday was a single repricing. |
