**Updated November 5, 2026 — U.S. trading session still underway at the reporting
cutoff.** Wall Street’s technology-heavy Nasdaq fell sharply on Thursday as investors
reassessed the economics of artificial-intelligence infrastructure, the cost of 
financing new data centers and the prospect of tougher oversight following the U.
S. midterm elections. **Closing-market update (November 5, 2026):** The Nasdaq Composite
ultimately closed down **5.52%**, entering correction territory, according to Reuters
and Associated Press. The S&P 500 fell 4.36% and the Dow Jones Industrial Average
declined 3.44%. These confirmed closing figures supersede the earlier intraday indications
described below. Sources: [Reuters closing-market report](https://www.reuters.com/business/sp-500-futures-steady-after-midterm-rally-nasdaq-lags-chip-weakness-2026-11-05/)

## What drove the selloff?

Reuters reported that the Nasdaq was down around 5% during Thursday’s session, with
chipmakers and AI-infrastructure businesses among the hardest hit. The precise decline
can change before the market closes. The selling followed a period in which investors
had priced substantial future earnings growth into companies supplying AI processors,
servers and data-center capacity.

Those expectations are sensitive to several pressures at once: higher borrowing 
costs make large construction projects more expensive; energy and infrastructure
constraints complicate delivery schedules; and investors increasingly want evidence
that AI spending will translate into durable cash flow. Election results have added
uncertainty over future approvals and regulation, but it would be misleading to 
attribute every share-price move to a single political cause.

## Why the wider market matters

AP reported broad weakness across major U.S. stock indexes, while Reuters described
the rout spreading into global equities. Declines in semiconductor stocks can have
outsized effects on indexes because several AI-related companies carry substantial
market weights. A technical market correction refers to a fall of at least 10% from
a recent peak; it does not by itself establish an economic recession or a lasting
collapse in demand for AI.

## What investors should watch next

Three developments will help distinguish a short-lived valuation reset from a deeper
investment slowdown: whether major cloud companies maintain their capital-spending
plans, whether financing for smaller data-center operators tightens further, and
whether earnings forecasts are revised downward. Investors should also check the
_official closing index levels_ rather than treating afternoon quotes as final results.
