Nasdaq 100 Erases $2.5 Trillion as Democratic Sweep Fuels AI Buildout Fears
3 articles · Updated · Reuters · Nov 5
Summary
A 6.4% plunge in the Nasdaq 100 wiped out $2.5 trillion in market value, while the broader Nasdaq Composite fell 5.5% into correction territory—nearly 12% below its October 6 record.
Investors sold AI-linked stocks on fears a Democratic midterm sweep will bring tougher scrutiny and local resistance to data centers, potentially slowing the infrastructure buildout behind the AI boom.
Chip and neocloud names led the rout: the Philadelphia Semiconductor index sank 12%, AMD dropped 17%, Nvidia lost 9%, Nebius fell 15% and CoreWeave slid 10%.
Credit stress sharpened the selloff as CoreWeave's 5-year CDS widened to a record 1,267.9 basis points; UBS estimates about 30% of expected 2028 U.S. data-center capacity additions could be at risk from construction pauses.
The drop deepened doubts about AI spending returns, with analysts warning more selling could spill into Asian markets and even complicate the timing of Anthropic's expected IPO.
With hyperscalers needing $300 billion in annual revenue to break even, is the $2.5 trillion tech selloff the start of an AI winter?
Can the AI industry survive its massive infrastructure costs, or will opaque private credit structures trigger a larger financial crisis?
November 2026 Tech Crash: $5 Trillion Wiped Out as AI Infrastructure Faces Political and Regulatory Headwinds
Overview
In November 2026, U.S. tech stocks plunged after Democrats won control of Congress and key states, triggering new moratoriums and restrictions on data center construction. This political shift, combined with hints of higher interest rates and weak chip sales forecasts, led to a sharp market sell-off, especially in semiconductor and leveraged neocloud companies. As 30% to 45% of planned U.S. data center capacity faced delays or cancellations, operators began shifting investments to less restrictive regions and adopting off-grid power solutions. Meanwhile, surging data center electricity demand exposed grid bottlenecks, driving major investments in smart grid infrastructure and reshaping capital flows across technology and energy sectors.
