The Nasdaq Composite fell 5.52% on Thursday, Nov. 5, and closed in correction territory, erasing an estimated $2 trillion to $2.5 trillion in market value, depending on the tally. Reuters and Fox Business tied the drop to Democratic wins in the midterm elections, which raised the odds that data centers get built later and on tougher terms. Chip and data-center stocks fell roughly two to four times as much as Meta, a major spender on AI infrastructure.
What happened on Thursday
The Nasdaq’s decline was its largest one-day percentage drop since the April 2025 tariff selloff, Reuters reported. The S&P 500 fell 4.36%, and the Dow Jones Industrial Average lost 1,833 points, or 3.44%. All market figures here reflect Thursday’s close.
The damage concentrated in the suppliers. The Philadelphia Semiconductor Index fell about 12%, which Reuters called its second-largest one-day fall on record. Nvidia dropped about 9%, and AMD and Micron each lost roughly 17%. Applied Digital, IREN and Nebius, which operate data centers, each fell more than 14%, Fox Business reported.
The buyers of that hardware held up better. Meta dropped about 4%, and Amazon and Alphabet also declined. Markets had rallied on Wednesday, and Reuters said investors then reassessed their initially benign reaction to the Democratic sweep.
Why investors sold the suppliers first
The data suggests the market priced timing risk. JonesTrading’s Michael O’Rourke told Reuters the lasting theme of the election is “the slowdown of the data center buildout,” pointing to Democratic wins in governorships. Fox Business reported that analysts see the AI infrastructure buildout becoming slower and more expensive. UBS analysts estimated that around 30% of expected U.S. data-center capacity additions in 2028 could face construction pauses, Reuters reported.
The politics did not start Thursday. In July, New York Gov. Kathy Hochul ordered state regulators to stop granting new permits for large-scale data centers for up to one year, and Newsweek counted governor candidates in at least a dozen states who backed similar pauses. AFP reported in August that anger over electricity bills and noise had turned data centers into a midterm issue for Democrats and a growing number of Republicans. The Trump administration, The Week reported, invited Republican governors to sign a pledge that developers pay their fair share of energy and water costs.
Spending worries predate the election. Reuters reported on Nov. 3 that the Nasdaq-100 had entered a correction on Monday as investors grew wary of Big Tech’s AI spending and saw little evidence of adequate returns. Alphabet reported on Oct. 28 negative free cash flow of about $9.1 billion for the third quarter, its second straight negative quarter, on capital spending of $51.4 billion. Amazon reported on Oct. 29 trailing twelve-month free cash flow of negative $42.4 billion, against positive $14.8 billion a year earlier.
Neither company reported weaker demand. AWS revenue grew 39% to about $46 billion, and Alphabet Chief Financial Officer Anat Ashkenazi put Google Cloud’s backlog at $561 billion. Both companies also say spending will rise: Amazon CEO Andy Jassy said the company expects to spend meaningfully more in 2027 than the roughly $220 billion planned for 2026, and Ashkenazi said Alphabet expects capital spending to increase significantly in 2027.
What the selloff does not show
Moves of this size can reflect positioning and forced selling as much as new information. Gizmodo, citing the Wall Street Journal, linked the rout to weak earnings from AI-sector companies as well as the election results. The tape does not read as a uniform exit from AI, though: Meta fell about 4% while Nvidia lost about 9% and AMD and Micron about 17%. Follow-through in the sessions ahead will show how much of Thursday’s move was repricing and how much was positioning.
What it means for operators
My take is that the useful reading concerns delivery dates and contract terms. A capacity contract is a bet on a delivery date as much as on demand. A buildout that arrives late, or that costs more because developers cover their own power, breaks a 2027 plan without any change in what customers want.
Cloud and GPU buyers should test 2027 plans against a slower-delivery scenario. Check the delivery-date clauses and remedies in capacity contracts, the price-adjustment terms, and how much of a commitment depends on a single neocloud, since data-center operators fell more than 14% in one session.
What would prove this wrong
Three signals test the thesis. Nvidia reports on Nov. 17, and its language on supply, power and customer timing will show whether orders are slipping or only the schedules. Hyperscaler guidance for 2027 comes next, and Alphabet has said it will provide further details on its fourth-quarter call. A cut would point to demand doubts, while a raise would say the money is coming and the open question is how fast it can be spent. The third signal is legislative: whether other governors follow New York with pauses of their own rather than campaign promises.
Thursday’s selloff put a price on delay. Buyers who plan 2027 around every facility opening on schedule hold the exposure the market just repriced. Nvidia’s Nov. 17 report will start to show how much of that exposure is real.
