What happened
Chip stocks (SOX) fell 12% on Thursday, their worst day since 2020, after Democrats' midterm wins in data-center states stoked fears of a slower AI buildout. Democrats won control of Congress and made gains in Texas and Georgia, two states with many planned data centers. Some party leaders, including Sen. Bernie Sanders, called for a national pause on new data centers. Investors also cashed in gains on this year's best-performing stocks, which added to the drop. Chip stocks bounced about 4% on Friday.
Why it matters
Nvidia (NVDA) and other chipmakers earn much of their money from companies building huge AI data centers. If Democrats slow new data centers through local rules, power-price limits or a national pause, those chip orders could grow more slowly. Nothing has become law yet, so the selloff reflects worry about what might come, not a new rule.
