Wall Street faced a significant sell-off on November 5, resulting in an estimated $1 trillion loss in aggregate market capitalization across major firms. The downturn occurred swiftly after the U.S. midterm election results, prompting immediate reactions from political figures.
Trump Links Market Plunge to Democratic Victories
Former U.S. President Donald Trump publicly blamed the Democratic Party for the substantial market decline. Taking to Truth Social, Trump linked the financial instability directly to the recent political shifts, stating, "The Stock Market suffered one of the Worst Days in History based on the results of the Election." He further asserted that the market's previous gains were undone by what he termed "Dumocrats," reassuring his followers of a future resurgence.
"The Stock Market suffered one of the Worst Days in History based on the results of the Election. Such a sad thing to watch! It took so much work to get us to a level that no one has ever seen before, and then this. Your 401(k)s have, therefore, dropped. Remember, it wasn’t Republicans, it was Dumocrats. Do not fear, however, we will soon, one way or the other, be BIGGER AND STRONGER THAN EVER BEFORE. MAKE AMERICA GREAT AGAIN!" – President DONALD J. TRUMP
Major Indices Hit Hard
The market rout reversed post-election gains, pushing several benchmark indices into correction territory. The Nasdaq Composite plunged over 5%, marking its worst single-day performance since April 2025. The Dow Jones Industrial Average retreated more than 1,800 points, over 3%, while the S&P 500 pulled back more than 4%. The small-cap Russell 2000 also concluded the session in correction territory.
AI Sector and 'Magnificent Seven' Bear the Brunt
Fears surrounding a slowdown in the artificial intelligence (AI) buildout heavily drove the rout, severely impacting chipmakers and AI infrastructure firms. The collective market capitalization of the 'Magnificent Seven' – Apple, Microsoft, Nvidia, Alphabet, Amazon, Meta Platforms, and Tesla – erased over $1 trillion. Notably, Nvidia led the downturn, losing nearly $450 billion in market cap in a single day, with shares dropping over 9% and turning negative for the year. Qualcomm also fell significantly after a disappointing earnings forecast.
Democrats Target Data Center Expansion
Wall Street's anxieties were amplified by newly elected and returning Democrats signaling immediate legislative plans aimed at the AI buildout, particularly data center expansion. Concerns over rising interest rates, heavy capital requirements, and potential low revenue relative to debt loads have created a challenging environment for AI infrastructure companies.
- National Moratorium Calls: Senator Bernie Sanders (I-Vt.) called for a "National data center moratorium now," citing local referendum victories restricting data centers and warning against "Big Tech oligarchs."
- House Priorities: Representative Yassamin Ansari (D-Ariz.) and Congressional Progressive Caucus Chair Representative Greg Casar (D-Texas) declared pausing AI development a Day 1 priority for the House's Democratic majority.
- State-Level Opposition: Victories in states like South Carolina, Ohio, Pennsylvania, and Texas saw Democrats campaigning on or reiterating opposition to unchecked data center influence, emphasizing community control over Big Tech development.
The U.S. market rout had ripple effects, spreading to Asian counterparts on November 6, with Korea’s Kospi hitting its circuit breaker and indices across Japan and Taiwan experiencing significant declines.
