TL;DR
The Nasdaq Composite fell 5.52% on Nov. 5, its steepest one-day decline since April 2025, while the Nasdaq-100 dropped 6.36%. Investors weighed the prospect that election results could bring more oversight and tougher conditions for AI data center projects, but no new federal rules have passed and many projected effects remain uncertain.
The Nasdaq Composite fell 5.52% on Thursday, Nov. 5, its largest one-day decline since April 2025, as investors assessed whether the U.S. midterm election results could slow or raise the cost of AI data center construction. The Nasdaq-100 fell 6.36%; Reuters estimated that the decline erased about $2.5 trillion in market value from the index’s 100 largest non-financial companies.
Nasdaq’s closing data put the Composite at 24,315.00, down 1,421.51 points. The exchange data showed the Nasdaq-100 at 26,629.81, down 1,807.36 points. The Composite’s decline was its biggest since April 4, 2025, when it fell 5.82% amid the tariff shock. It closed 11.9% below its record on Oct. 6, meeting the usual definition of a market correction: a drop of at least 10% from a recent peak.
The selloff was steepest in chips and other companies tied to data center investment. The PHLX Semiconductor Index fell 12.25%. Reuters reported that Nvidia shares dropped 9% and AMD fell 17%, while several data center operators lost more than 14%. Amazon and Alphabet each fell 2.2% on Thursday, and Microsoft declined 3.6%, Reuters reported. The VIX, a measure of expected stock-market volatility, had its largest increase since December 2024, according to Reuters.
The trading followed a mixed session on Wednesday. The Composite rose 1.44% on Nov. 4, even as Reuters reported declines among some data center operators and power companies. Amazon and Microsoft rose about 6% during that session. A market theory described by Reuters was that existing data centers could become more valuable if fewer new facilities were built. Thursday’s broad decline showed that investors were also reassessing the effect of policy uncertainty across the sector.

Election Results Put Data Centers in Focus
The market reaction reflects uncertainty about whether political changes could affect the cost, timing and approval of new data centers. These projects need substantial electricity and water, as well as permits, grid connections and, in some cases, tax incentives. Changes in those conditions could affect both construction schedules and the projected returns that investors assign to technology companies and infrastructure providers.
That exposure reaches beyond data center operators. Chipmakers depend on continued investment in computing infrastructure, while utilities and power suppliers may benefit from new demand but face disputes over who pays for grid upgrades and electricity. The one-day market decline does not establish that projects will be canceled or that company earnings will fall by a particular amount. It shows that investors are pricing in a wider range of possible outcomes.
For readers and savers, the distinction between policy risk and enacted policy matters. Election outcomes can change oversight and local decision-making, but the reported selloff followed expectations and concerns, not a new federal law restricting data centers.

From Election Outcomes to Project Permits
Reports cited by the source describe Democrats winning control of both chambers of Congress and flipping five governorships: Texas, Georgia, Ohio, Iowa and Nevada. The National reported that those states contain 37% of planned U.S. data center capacity, based on its analysis of Cleanview project data; it put Texas’s share at 22.8%. Those figures concern planned capacity, not facilities already built or guaranteed to proceed.
The incoming governors of Texas, Georgia and Ohio were reported to have promised pauses or restrictions on large data center projects. The incoming Texas governor also promised a moratorium on new construction and greater community input, according to The National. Governors can influence state policy and appoint utility regulators, while local governments and utilities have roles in siting, permits and power access. The National also reported that unofficial results from local votes in ten states showed 46 of 47 measures opposing data center development through proposed bans, caps or pauses.
These developments followed weeks of concern about the expense of AI infrastructure. The election added a political dimension to questions investors were already asking about how much technology companies would spend on data centers and when those investments would pay off. The results may influence future decisions, but they do not by themselves change existing permits or guarantee that planned projects will be abandoned.

Rules and Project Timelines Remain Unsettled
No new federal law governing data center construction had passed as of the reported market close. The source material says President Donald Trump retains veto power and cites analysts who expect political gridlock rather than sweeping federal changes. The precise effect of the election on congressional investigations, state rules and individual project approvals is not yet known.
It is also unclear how many planned facilities will be delayed, redesigned or canceled, and how any added costs would affect company earnings. The estimate that about 30% of planned 2028 capacity additions could be at risk is an analyst estimate, not a confirmed outcome. The local measures cited were unofficial results, and their final status and legal effect were not established in the material. The market decline alone cannot show how much of the move reflected election concerns rather than other investor decisions.
Investors Await Policy and Company Decisions
Investors will be watching whether newly elected lawmakers and governors pursue the oversight, project pauses or changes to tax incentives described in reporting. Upcoming decisions by state governments, utilities and local authorities will help clarify whether data center projects face different requirements for permits, electricity, water or community consultation.
Companies’ future disclosures and investment plans may also show whether they expect to change construction schedules or spending. Until those decisions become clearer, the reported election pledges and capacity-risk estimates remain potential influences rather than confirmed changes to the build-out. The next market sessions will show whether the Nov. 5 drop continues, but the source material does not establish what direction shares will take.
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.
What does the $2.5 trillion figure refer to?
Reuters estimated that about $2.5 trillion in market value was erased from the Nasdaq-100, which tracks 100 large non-financial companies listed on the exchange. It is not a figure for every Nasdaq-listed stock.
Did the election create new federal restrictions on data centers?
No new federal law had passed as of the reported market close. Investors were reacting to possible future oversight and policy changes, not to an enacted federal restriction.
Are the data center projects in those states canceled?
The reported election results and policy promises do not confirm that projects have been canceled. The number of projects that may be delayed or changed remains unclear.
Why were chip stocks hit particularly hard?
Investors considered whether slower or more expensive data center construction could reduce demand for the chips and infrastructure used in AI computing. The share-price declines do not by themselves establish a change in company demand or earnings.
