The Nasdaq 100 suffered a massive sell-off on Thursday, losing approximately $2.5 trillion in market value as investors reassessed the implications of the Democrats’ sweeping victory in the US midterm elections. The rout intensified concerns that political gridlock, tighter regulatory scrutiny and growing opposition to data-center development could slow the expansion of artificial intelligence (AI) infrastructure.
The scale of the decline marked a dramatic reversal from Wednesday’s initial market reaction, when US stocks rallied on hopes that the conclusion of the midterm elections would reduce political uncertainty and improve investor sentiment. That optimism proved short-lived as investors began reassessing the potential consequences of a Democratic-controlled Congress for corporate investment, particularly the enormous spending commitments underpinning the AI boom.
By Thursday’s close, the technology-heavy Nasdaq Composite had plunged 5.5%, while the Nasdaq 100 fell 6.4%, wiping out approximately $2.5 trillion in market value. The Nasdaq Composite also entered correction territory, having declined nearly 12% from its record closing high on October 6.
The broader market suffered substantial losses as well. The S&P 500 dropped 4.4%, while the Dow Jones Industrial Average fell 3.4%, marking Wall Street’s steepest daily sell-off since the April 2025 market turmoil triggered by President Donald Trump’s tariff announcements.

The Philadelphia Semiconductor Index (.SOX) plunged approximately 12%, touching its lowest level in more than six months. Nvidia (NVDA) declined 9%, while Advanced Micro Devices (AMD) tumbled 17%, reflecting mounting pressure on companies at the centre of the AI investment cycle.
The sell-off extended beyond chipmakers to cloud infrastructure providers, data-centre operators, hyperscalers and companies supplying electricity and equipment to the rapidly expanding industry.
AI Infrastructure Stocks Bear the Brunt of the Sell-Off
Companies directly exposed to the financing and construction of AI infrastructure suffered some of the steepest losses.
CoreWeave (CRWV), increasingly viewed as a barometer of investor sentiment towards heavily financed AI infrastructure businesses, fell approximately 10%. Its five-year credit default swap spreads widened to a record 1,267.9 basis points, according to S&P Global Market Intelligence data. The increase signals growing market concern about the company’s credit risk and ability to meet its financial obligations.
Another neocloud provider, Nebius (NBIS), plunged 15%, as investors reassessed the financial and operational risks facing companies whose growth depends heavily on sustained AI infrastructure spending.
The pressure was particularly severe among data-centre operators. Applied Digital (APLD), Cipher Digital (CIFR) and IREN (IREN) each lost more than 14%, reflecting concerns about the sustainability of the investment boom and the possibility that new projects could encounter regulatory, financing and construction delays.
The weakness also spread to utilities and equipment suppliers with substantial exposure to data-center expansion. GE Vernova (GEV) fell 7.4%, while Constellation Energy (CEG) declined 2.5%.
Microsoft (MSFT) dropped 3.6% following a Bloomberg News report that the company was tightening oversight of certain data-center projects involving Nebius, IREN and Nscale.
The latest developments highlight the growing vulnerability of companies whose valuations have been closely linked to expectations of uninterrupted investment in AI computing capacity, electricity generation and data-center construction.

Political Uncertainty Adds to Data-Center Expansion Risks
Investors are increasingly concerned that the Democrats’ sweeping midterm victory could result in greater scrutiny of the data-centre industry and complicate the approval and construction of new facilities.
Although the election results do not automatically introduce new restrictions, Democratic gains have raised expectations of stronger political and regulatory pressure on an industry facing growing opposition from local communities.
Concerns over electricity consumption, water requirements, pressure on local power grids and the environmental consequences of large-scale data-center development have become increasingly prominent in communities across the United States.
The political implications could be significant for an industry whose expansion depends on securing permits, electricity supplies, financing and public acceptance for facilities requiring billions of dollars in investment.
UBS analysts estimate that approximately 30% of anticipated US data-center capacity additions in 2028 could be exposed to potential construction pauses or delays. Such disruptions could undermine the growth assumptions underpinning valuations across the AI infrastructure sector.
The prospect of slower development has also raised concerns about future demand for advanced semiconductors, cloud computing services, electricity and related equipment.
Hyperscalers and Chipmakers Face Growing Pressure
The latest sell-off also spread to the world’s largest technology companies, including hyperscalers that have committed hundreds of billions of dollars to developing AI infrastructure.
Amazon (AMZN) and Alphabet (GOOGL) each declined approximately 2.2%, reversing the relative resilience they had demonstrated during Wednesday’s initial post-election rally.
The previous session had seen investors consider whether slower data-center construction might eventually moderate the escalating capital expenditure commitments of major technology companies. However, Thursday’s trading suggested that concerns about disrupted infrastructure development and reduced demand for AI-related products were outweighing any potential savings from lower investment.
Microsoft’s decline further reflected concerns about the financial and operational challenges facing the data-center industry.
Meanwhile, semiconductor companies remained under intense pressure. Nvidia and AMD suffered substantial losses, while the broader Philadelphia Semiconductor Index recorded a decline of approximately 12%, one of its largest single-session drops in recent years.
Qualcomm (QCOM) also came under pressure after reporting quarterly smartphone-chip sales that fell short of Wall Street expectations, adding another source of weakness to an already battered technology sector.
Investors Reassess the Economics of the AI Boom
The latest market turbulence reflects a growing reassessment of the economics underpinning the AI investment boom.
For much of the past two years, enthusiasm over the transformative potential of artificial intelligence has supported extraordinary valuations for semiconductor manufacturers, cloud computing providers and companies involved in building the infrastructure required to support increasingly sophisticated AI applications.
However, investors are becoming more demanding about the financial returns from these investments.
The development of large-scale AI infrastructure requires enormous capital commitments, including spending on advanced processors, data-centre facilities, electricity generation, cooling systems and network equipment.
While demand for AI computing capacity remains substantial, questions are mounting over whether the revenues and profits generated by the technology will ultimately justify the scale of investment.
Smaller infrastructure providers face additional challenges because their business models frequently depend on substantial borrowing and continued access to capital markets. Higher financing costs and uncertainty over future demand could make it more difficult for these companies to sustain ambitious expansion plans.
The market reaction also suggests that investors are becoming less willing to reward AI-related companies solely on the basis of anticipated future growth, particularly when profitability and cash-flow generation remain uncertain.
A Turning Point for the AI Investment Trade?
Thursday’s rout exposed the growing sensitivity of technology valuations to political developments, financing conditions and concerns about the practical limitations of expanding AI infrastructure.
The Democrats’ midterm victories have introduced another layer of uncertainty into an industry already facing questions about investment returns, borrowing costs and the pace at which new facilities can be developed.
The immediate market consequences were particularly severe for semiconductor manufacturers and neo cloud providers, but the pressure extended across the broader technology and energy sectors, certainty and growing.
