elperiodicodearagon.com (Spanish) —

A sweeping Democratic victory in US legislative elections triggered a severe stock market selloff in the artificial intelligence industry, erasing nearly $2.5 trillion in value overnight. The Nasdaq fell up to 6% amid fears of new congressional oversight and investor skepticism toward the sector. The losses mark the worst day since April 2, 2025, when Donald Trump announced tariff policies. Fourteen AI companies analyzed lost a combined $1.94 trillion in market capitalization, with Micron Technology, AMD, and Dell suffering the steepest declines of 17.46%, 17.26%, and 14.89% respectively. The "Magnificent Seven" tech giants lost over $1 trillion in a single session, led by Nvidia's $447.5 billion drop. Elon Musk's companies also suffered, with Tesla falling 10.77% and SpaceX declining 9.05%, reflecting both AI skepticism and the defeat of Silicon Valley-backed candidates.
