Nasdaq falls 5.5% on fears of data center regulation: the market is pricing in politics, not technology

By CNN Chile · November 5, 2026.

Wall Street suffered one of its worst sessions in years on Thursday. According to CNN Chile, the Nasdaq Composite fell 5.52% to 24,315 points and entered correction territory, meaning a drop of more than 10% from its all-time high in October. The S&P 500 lost 4.30% and the Dow Jones 3.44%.

According to the outlet, the sell-off wiped out more than $2 trillion in market value in a single day and erased Wednesday's rally, when stocks rose after the midterm election results came in.

The trigger, according to the source, is investor fear that Democratic control of Congress and the party's wins in state elections will lead to more regulation, higher costs or pauses in data center construction. The effect of data centers on electricity prices was a campaign issue.

Chips took the hardest hit. The Philadelphia Semiconductor Index plunged 12.25%. Nvidia fell 9.26% to $181.60 per share. SanDisk (22.26%), Micron (17.46%), AMD (17.26%), Broadcom (10.43%) and Intel (10.33%) also fell.

AI infrastructure firms suffered just as much: CoreWeave lost 9.83%, Palantir 9.73% and Oracle 6.93%. Big Tech held up better: Meta fell 3.96%, Microsoft 3.58%, Alphabet 2.20%, Amazon 2.19% and Apple 1.53%.

The cause deserves some nuance. CNN Chile points to an additional factor: Qualcomm forecast mobile chip sales below expectations, which fueled doubts about demand. And Tesla (-10.77%) and SpaceX (-9.05%) fell, according to the analysts cited, because the defeat of Texas's Republican governor complicates a potential merger between the two. Attributing the entire drop to AI regulation is an oversimplification.

Our take: the market is not questioning what AI can do, but who will pay its energy bill and under what rules. The decline is concentrated in the physical layer (chips, memory, data centers), not among those who use the models. That distribution reveals where the real bottleneck lies: electricity, permits and social acceptance.

In general, a 5-6% drop in a single day tends to mix panic, leveraged positions and profit-taking after months of gains. One day does not make a trend, and we do not yet know what regulation will be passed, if any. The market is pricing in a scenario, not a law.

There is a legitimate tension here, and the short term is tough. If household electricity bills rise because of data centers, it is reasonable for voters to demand conditions. Regulating based on evidence (who pays for the grid, how the energy is generated) is healthy. Regulating out of panic, by curbing computing capacity, would be a costly mistake.

In the long term, the underlying thesis does not change. Eradicating diseases and generating abundance requires compute and energy in large quantities. The most sensible way forward is not to build less, but to build with clean, abundant generation, and with costs that do not fall on those who have the least. Whoever solves that political and energy equation will win the next decade; this week's volatility is the price of starting to solve it.

What to watch: tomorrow's jobs report and Congress's first concrete proposals on data centers. That will show whether the fear was justified or overblown.
