AI stocks plunge after US midterm election data center sentiment rebound

The author reviews the sharp drop in the US stock market's AI sector: the Nasdaq fell more than 5% during trading, the Philadelphia Semiconductor Index dipped nearly 11%, Nvidia dropped nearly 9%, and the Nasdaq lost nearly $1.8 trillion in market value in a single day. The backdrop is that the Democrats took control of both chambers in the midterm elections. Arizona Representative Andy Biggs proposed suspending advanced AI development. Previously, Sanders and others proposed the '2026 Artificial Superintelligence Prohibition Act' in September, drawing a line at training compute power of 10^25 FLOPS and stipulating that individuals violating the rules face up to 20 years in prison, while companies can be forcibly dissolved.
