TL;DR
The Nasdaq Composite fell 5.52% on Nov. 5, its steepest one-day decline since April 2025, while semiconductor shares dropped more sharply. Reuters attributed the selloff partly to investor concerns that election results could bring greater oversight and higher costs for AI data center projects; no new federal law has been passed, and the potential effects remain uncertain.
The Nasdaq Composite fell 5.52% on Nov. 5, while the Nasdaq-100 dropped 6.36%, as investors weighed whether election results could slow or raise the cost of the U.S. AI data center build-out. Reuters reported that the Nasdaq-100 decline erased about $2.5 trillion in market value; that estimate applies to the index’s 100 largest non-financial companies, not every Nasdaq-listed stock. No new federal data center law has been enacted.
Nasdaq’s published closing data put the Composite at 24,315.00, down 1,421.51 points. The index’s last larger daily decline was a 5.82% fall on April 4, 2025, during the tariff-related market shock. The Nasdaq-100 closed at 26,629.81, down 1,807.36 points. It was 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.
Technology and infrastructure-linked shares bore much of the pressure. The PHLX Semiconductor Index fell 12.25%. Reuters reported Nvidia shares lost 9% and AMD fell 17%, while several data center operators declined by more than 14%. Amazon and Alphabet each fell 2.2% and Microsoft lost 3.6% on Thursday, according to the source material. The VIX, a measure of expected market volatility, recorded its largest rise since December 2024, Reuters reported.
The political concern centers on whether incoming officials will alter the conditions that shape new facilities: permits, electricity access, water costs and tax incentives. Reuters and The National reported that election outcomes prompted expectations of more oversight and possible pauses on projects. Those are investor concerns and forecasts, not evidence that construction rules have already changed. The source material says a UBS estimate put about 30% of planned 2028 capacity additions at risk; that is an estimate, not a confirmed cancellation figure.

Permits and Power Shape Project Costs
Data centers require large amounts of electricity and significant investment in land, equipment and grid connections. If regulators or local governments make those connections harder to secure, reduce tax breaks, or require developers to shoulder more power and water costs, projects could take longer or become more expensive. That prospect matters to investors in chipmakers, cloud companies, utilities and data center operators, as well as communities negotiating the impacts of new facilities.
The market move also shows how political risk can affect expectations for AI infrastructure before a law changes. The reported losses reflect investor repricing and concern about future conditions; they do not establish that AI demand has collapsed or that planned projects will be abandoned. Share prices are volatile, and a single session cannot establish the long-term direction of the sector.

Election Results Meet Data Center Expansion
The selloff followed election results that, according to the source material, gave Democrats control of both chambers of Congress and flipped several governorships. Reuters reported that investors anticipated increased congressional scrutiny of technology and commerce. The National reported Democratic wins in Texas, Georgia, Ohio, Iowa and Nevada, states it said account for a substantial share of planned data center capacity. The source attributes a 37% share to an analysis of Cleanview project data, including 22.8% for Texas; those figures describe planned capacity, not facilities already operating.
The incoming governors’ positions may matter because state governments can influence utility regulation, grid access and economic incentives. The National reported that the incoming Texas governor promised a moratorium on new data center construction and that incoming leaders in Georgia and Ohio pledged pauses on large projects. Local ballot measures also drew attention: the source says an unofficial count found 46 of 47 measures in ten states opposing projects through proposed bans, caps or pauses. Those results and their legal effects require care: unofficial vote counts and campaign pledges do not by themselves establish what rules will ultimately take effect.
The market’s reaction shifted during the two sessions. On Nov. 4, the Composite rose 1.44%, even as Reuters reported declines among data center operators and power companies; Amazon and Microsoft gained about 6% during that session. On Nov. 5, that contrast gave way to broad losses, including among major cloud companies. The sequence does not prove that election outcomes alone caused Thursday’s drop, but it places the policy debate among the factors investors were considering.

Policy Changes Remain Unsettled
The precise causes of a broad market selloff cannot be established from price movements alone. Reuters connected the losses to election-related concerns, but the source material also describes earlier volatility and existing investor worries about the cost of AI spending. It remains unclear how much of Thursday’s decline reflected data center policy rather than other market factors.
No new federal law governing AI data centers has passed, and the source says President Donald Trump retains veto power. The extent of future congressional oversight, the terms of any state-level pauses, and the final outcomes of local measures are not settled here. The UBS figure about planned 2028 capacity is a forecast; the source does not establish its assumptions or how many projects, if any, will actually be delayed or canceled. The market loss estimate also refers to Nasdaq-100 companies, not the entire U.S. technology sector.
Watch Oversight and State-Level Decisions
Investors and project developers will be watching for congressional hearings, state policy proposals, utility commission decisions and details of any promised construction pauses. Those developments could clarify whether campaign positions become binding rules and how they affect permits, grid connections, incentives and project costs. The source material does not identify a specific date for a new federal measure or a final decision on the state proposals.
Upcoming company results and capital-spending disclosures may also show whether cloud and technology firms are changing their infrastructure plans. Until policy decisions and project-level responses are clearer, the scale of any effect on U.S. data center capacity remains uncertain. This report is not investment advice; technology stocks can be volatile and investors can lose money.
Key Questions
How far 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 the exchange data cited in the source material.
What does the reported $2.5 trillion loss cover?
Reuters’ estimate refers to market value erased from the Nasdaq-100, which tracks 100 large non-financial companies listed on Nasdaq. It does not represent losses across every Nasdaq-listed stock.
Did the election change federal data center rules?
The source material says no new federal law has passed. Investor concerns focused on possible future oversight and changes to state or local permitting, incentives and infrastructure decisions.
Are planned AI data center projects already being canceled?
The source material does not confirm widespread cancellations. It cites policy pledges and a UBS estimate that about 30% of planned 2028 capacity additions could be at risk, but that figure is a forecast rather than a record of canceled projects.
