A stock market selloff on Thursday, November 5, 2026, erased about $3 trillion in U.S. market value as artificial intelligence and chip stocks fell, and President Donald Trump blamed the losses on voters who delivered Democratic wins in the November 3 midterm elections.

The Nasdaq Composite fell 5.52%, the S&P 500 fell 4.36% and the Dow Jones Industrial Average fell 3.44%, or 1,833 points, on November 5, according to closing figures reported by International Business Times. The drop followed the Dow’s best post-midterm session in 44 years, Fortune reported. The selloff centered on data centers, an issue that also shaped Alabama’s 2026 governor’s race.

Key Details

• Market value lost: About $3 trillion in S&P 500 market value on November 5, 2026, according to Fortune and International Business Times.
• Chip stocks: The Philadelphia Semiconductor Index fell 12.2% on November 5, its second-largest one-day percentage decline on record, International Business Times reported.
• Prior session: The Dow rose 3% to 53,356.12 and the S&P 500 rose 1.6% to 7,688.62 on November 4, 2026.

What Caused the Stock Market Selloff?

Fortune and International Business Times tied the November 5 stock market selloff to concerns that midterm results could slow construction of the data centers that power artificial intelligence. Of 41 local data center measures on November 3 ballots, 40 produced results favoring restrictions, International Business Times reported, citing Ballotpedia.

Fortune also cited the Democratic sweep of Congress and the Texas governor’s race, in which Democrat Gina Hinojosa defeated Republican Gov. Greg Abbott. Fortune listed other factors, including an overnight selloff in Asian markets, weaker technology earnings and a rebound in oil prices.

Chipmakers took the largest losses on November 5. AMD fell about 17%, Nvidia fell more than 9% and Broadcom fell about 10%, International Business Times reported. All 11 S&P 500 sectors closed lower, with technology down more than 7%, according to the same report.

What Did President Trump Say About Voters and the Market?

President Donald Trump blamed the selloff on Democrats and the voters who backed them. “The Stock Market crashed today because the Dumocrats had a big Tuesday — So sad to see, you only have yourselves to blame!” Trump wrote on Truth Social on November 5, the Washington Examiner reported.

President Trump added in another post, “Your 401(k)s have, therefore, dropped. Remember, it wasn’t Republicans, it was Dumocrats,” according to International Business Times.

One day earlier, on November 4, President Trump wrote on Truth Social that the “Stock Market just hit another Record High” and that “Your 401(k)s are through the roof,” Gray News reported.

The Huntsville Commerce Report did not find a published response to the posts from Democratic congressional leaders or the Democratic National Committee as of Friday morning, November 6. Fortune reported that unnamed analysts and economists argued political pushback “could let air out of an inevitable AI bubble without popping it.”

How the Data Center Debate Played Out in Alabama

Data centers were a central issue in Alabama’s 2026 governor’s race between Republican U.S. Sen. Tommy Tuberville and Democrat Doug Jones, a former U.S. senator. Tuberville said new data centers should pay their own infrastructure and electricity costs, WAFF 48 reported. Jones proposed a six-month to one-year pause on permitting new data centers.

The Associated Press projected Tuberville the winner of the Alabama governor’s race early Wednesday, November 4, WVTM 13 reported. Google said it would invest $1.5 billion across 2026 and 2027 to expand its Jackson County data center campus in North Alabama, The Huntsville Commerce Report reported in June 2026.

What This Means for North Alabama

Reporting on the November 5 selloff did not identify effects on specific Huntsville or North Alabama companies, and The Huntsville Commerce Report has not independently established any. HCR’s Alabama business news coverage will report regional company announcements as they are made.

Nasdaq futures rose about 1.2% before the opening bell on Friday, November 6, International Business Times reported, and Bloomberg reported that AI stocks rebounded Friday. More regional coverage is on HCR’s Huntsville business news page and Finance & Banking archive.
