TL;DR
The Nasdaq Composite dropped 5.52% on Nov. 5, its steepest daily fall since April 2025, as investors considered whether election results could slow or raise the cost of AI data center construction. The market reaction is confirmed, but potential policy changes remain uncertain: no new federal law has passed, and estimates of capacity at risk are forecasts, not decisions.
The Nasdaq Composite fell 5.52% on Thursday, Nov. 5, while the Nasdaq-100 dropped 6.36%, as investors weighed whether the U.S. midterm election results could make AI data center projects slower or more expensive. Reuters estimated that the Nasdaq-100 decline erased about $2.5 trillion in market value; that figure applies to the index’s 100 largest non-financial companies, not every stock listed on Nasdaq. No new federal restrictions have been enacted.
Nasdaq’s published closing data put the Composite at 24,315.00, down 1,421.51 points. The exchange data shows its largest one-day percentage decline since April 4, 2025, when it fell 5.82% during the tariff shock. The Composite closed 11.9% below its Oct. 6 record, placing it in correction territory, commonly defined as a decline of at least 10% from a recent peak. The Nasdaq-100 closed at 26,629.81, down 1,807.36 points.
Technology and infrastructure-related shares were hit particularly hard. The PHLX Semiconductor index fell 12.25%. Reuters reported that Nvidia lost 9% and AMD 17%, while several data center operators fell more than 14%. Amazon and Alphabet declined 2.2% and Microsoft 3.6%, Reuters reported. The VIX, a measure of expected market volatility, recorded its largest increase since December 2024, according to the news agency.
The selloff followed a mixed session on Wednesday, Nov. 4: the Composite rose 1.44%, even as data center operators and power companies fell, Reuters reported. Some investors had reasoned that fewer new facilities could make existing data centers more valuable. On Thursday, that argument gave way to concern about how political and regulatory changes might affect the wider technology investment cycle.

Data Center Costs Move Into Focus
The market reaction matters because AI investment depends on a large and continuing build-out of facilities, power supply and grid connections. If approvals take longer, incentives shrink, or developers shoulder more of the electricity and water costs, projects could become more expensive or be delayed. That could affect data center operators, utilities, chipmakers and the technology companies financing AI infrastructure.
But Thursday’s losses show investor concern, not proof that construction will slow. The connection between election outcomes and the day’s selloff is reported by Reuters and The National; the extent to which policy will change remains unsettled. Shares can respond to expectations before laws or agency decisions exist. Readers should distinguish that market interpretation from a confirmed change in project rules.
A UBS estimate cited in the source material says about 30% of planned U.S. data center capacity additions for 2028 could be at risk. That is an analyst estimate, not a government finding or a record of canceled projects. The underlying market stakes are substantial, but the estimate does not establish how much capacity will ultimately be built.

Election Results and Project Approvals
The source material identifies three channels through which election outcomes could affect data center plans: congressional oversight, state-level decisions and local votes. Reuters reported that Democrats won control of both chambers of Congress and are expected to chair committees overseeing technology and commerce from January. Analysts cited by Reuters expect more hearings and investigations into AI development and infrastructure.
The National reported Democratic gubernatorial wins in Texas, Georgia, Ohio, Iowa and Nevada. Its analysis of Cleanview project data said those states account for 37% of planned U.S. data center capacity, with Texas representing 22.8%. The outlet reported that the incoming Texas governor promised a moratorium on new data center construction and greater community input, while incoming governors in Georgia and Ohio pledged pauses on large projects. Those are reported campaign commitments; their scope, legal authority and implementation remain to be seen.
Governors can influence the environment for projects through appointments to utility regulators and decisions about state tax incentives. The source also reports that voters in small towns across 10 states considered local data center measures. Its count found 46 of 47 measures opposed projects through bans, size limits or pauses, based on unofficial results. Those reported local results do not by themselves establish a nationwide policy or determine what state and federal authorities will do.

Policy Changes Remain Unsettled
The market data confirms a steep one-day decline, but it does not establish that election results alone caused it. Nor does it show that data center projects have already been canceled or that new restrictions are in force. The source material describes investors’ concerns and analysts’ expectations, not enacted policy.
Several important details remain open: what oversight Congress will pursue, whether proposed state pauses will be adopted, and how utility regulators or local governments will handle permits, power connections and costs. The National’s local-vote tally was based on unofficial results. The UBS estimate that 30% of planned 2028 capacity additions could be at risk is a forecast, and its eventual accuracy is unknown.
The source says President Donald Trump retains veto power and that some analysts expect political gridlock rather than sweeping federal changes. The balance between federal action and state or local decisions is not yet clear. It is also uncertain how much of the Nov. 5 decline reflected data center policy fears rather than other market forces.
Watch Hearings, State Plans and Permits
Investors and project developers will be looking for concrete steps after the new Congress takes office in January, including committee hearings, investigations or proposed legislation. At the state level, attention will turn to whether incoming governors pursue their stated positions and whether those plans lead to formal orders, legislation or changes to permitting and incentives.
Local votes and decisions by utility regulators may provide earlier signals about project timelines, electricity costs and community requirements. Until those actions are documented, the Nov. 5 selloff is best understood as a market response to anticipated policy risk—not evidence that a nationwide data center crackdown has taken effect.
Key Questions
How much did the Nasdaq fall on Nov. 5?
The Nasdaq Composite fell 5.52% to 24,315.00. The Nasdaq-100 fell 6.36% to 26,629.81, according to Nasdaq closing data cited in the source material.
What does the reported $2.5 trillion loss refer to?
Reuters estimated that about $2.5 trillion in market value was erased from the Nasdaq-100, which tracks the exchange’s 100 largest non-financial companies. It is not a figure for every Nasdaq-listed stock.
Have new federal data center restrictions been passed?
No. The source material says no new federal law has passed. The market decline reflected concerns about possible future oversight and policy changes.
Why could state election results affect data center projects?
States can shape project conditions through utility regulation, grid connections, permitting and tax incentives. Incoming governors’ reported promises may affect expectations, but their plans still need to be carried out through the relevant processes.
Does the UBS estimate mean 30% of planned projects will be canceled?
No. The cited estimate says about 30% of planned U.S. capacity additions for 2028 could be at risk. It is a forecast about capacity, not confirmation that projects have been canceled.
