When the results of the United States midterm elections were announced on November 5, the nation’s capital buzzed with a rare sense of optimism. Salah‑Eddine Bouhmidi captured the mood succinctly: "Auf die Wahleuphorie folgt die Ernüchterung" – the euphoria of the vote is followed by disillusionment. Within hours, that disillusionment manifested on the trading floor.
Thursday’s market opened with a stark reversal of the post‑election rally that had lifted tech shares the day before. The Nasdaq Composite Index slumped by 795.08 points, while the broader S&P 500 and Dow Jones Industrial Average fell 127.74 and 351.87 points respectively. In percentage terms, the Nasdaq 100 shed 5% of its value. Analysts traced the sharp turn to growing concerns that the new congressional majority could tighten regulations on AI data‑center projects, potentially throttling the massive capital expenditures that have underpinned the sector’s recent surge.
Chris Beauchamp summed up the sentiment: "Tech stocks have gone into freefall, as investors focus on what the new guys in Congress will do to a sector so favoured by the current president and his coterie." The warning was clear: the sector’s privileged position could become a liability if policymakers decide to rein in the sprawling data‑center builds that power today’s generative‑AI models.
These divergent figures reflect the rapid, volatile nature of the trading day, where every tick amplified the perception of a market in freefall.
Absolute slaughter. Double digit losses for many AI companies. SpaceX 10% below IPO price, CoreWeave about to drop below its IPO price. Nvidia is down almost 10% The AI industry’s day of reckoning may have finally come. https://t.co/6S7mWPkzCY
The fallout was most visible among the chipmakers that supply the hardware backbone of AI workloads. Nvidia, the market’s poster child for AI acceleration, saw its shares tumble more than 6% in the session – a decline echoed by a separate report that listed a 7.5% drop in the company’s stock price. AMD fared even worse, with its shares crashing 12% and, in another tally, a 14.6% slide. Micron Technology was not spared, slipping 11% as investors reassessed demand for the memory chips essential to AI training and inference.
These moves were not isolated blips. The Philadelphia Semiconductor Index, a barometer for the broader chip industry, plunged more than 8%, underscoring how the sell‑off rippled across the entire semiconductor ecosystem.
The broader market metrics painted an equally stark picture. These divergent figures reflect the rapid, volatile nature of the trading day, where every tick amplified the perception of a market in freefall.

Compounding the tech sell‑off was a 10% recovery in oil prices. Higher energy costs have historically weighed on high‑growth, capital‑intensive sectors like technology, where profit margins can be squeezed by rising operating expenses. The oil rebound added another layer of headwinds, reinforcing the narrative that the tech rally was vulnerable to broader macroeconomic shifts.
At the heart of the market’s anxiety lies the prospect of tighter regulation on AI data‑center projects. These facilities, often the size of small towns, consume vast amounts of electricity and have become focal points for policy discussions around energy use, environmental impact and national security. The fear is that new rules could delay or curtail the construction of these centers, directly affecting the revenue pipelines of firms like Nvidia, AMD and Micron that depend on a steady stream of AI‑related orders.
US stock markets a sea of red…. Tech heavy Nasdaq down 5%, Dow Jones down 3%… Led by Tesla down 11% and Nvidia down 8.4%… Whereas alphabet down 1%, Amazon 2%. Clearly some focus on Musk post mid term Democrat sweep, and AI stocks given significant data centre backlash
The raw data from Thursday’s trading session tells a story of rapid re‑pricing:
- Nasdaq Composite down 795.08 points (or 1,285 points in an alternate tally) - S&P 500 down 127.74 points (or 287 points) - Dow Jones down 351.87 points (or 1,542 points) - Nasdaq 100 fell 5% - Nvidia shares dropped more than 6% (with a reported 7.5% slide) - AMD shares fell 12% (with a reported 14.6% slide) - Micron shares slid 11% - Philadelphia Semiconductor Index plunged over 8% - Oil prices recovered 10%
Taken together, these figures illustrate a market that swiftly moved from optimism to caution, with AI‑centric equities bearing the brunt of the shift.
The immediate aftermath leaves investors grappling with two intertwined uncertainties: the political calculus of a newly empowered Democratic Congress and the macro‑economic backdrop of rising energy costs. While the AI sector remains a cornerstone of the current tech narrative, the recent volatility serves as a reminder that policy and commodity shocks can quickly erode even the most robust rally.
For newcomers watching the market, Thursday’s episode offers a textbook case of how political outcomes, regulatory expectations and commodity price swings can converge to reshape investor sentiment in a single day. The next few weeks will reveal whether the sell‑off is a temporary correction or the opening act of a broader recalibration of AI‑driven valuations.
The story is still unfolding, but one thing is clear: the era of unchecked AI exuberance has met its first serious test, and the market’s response will set the tone for the sector’s trajectory in the months ahead.
