US stocks experienced a roller-coaster plunge, chip stocks were washed out, the Nasdaq erased the mid-term election gains in 6 minutes

US stocks maintained a rise for only one day after the midterm elections in 2026, plunging sharply on November 6. The Nasdaq index dropped by 5.5% to its largest single-day decline since April 2025, wiping out all post-election gains within 6 minutes. Chip and AI industry stocks were sold off, with the Philadelphia Semiconductor Index falling by more than 12%. Nvidia's market value evaporated by nearly 450 billion US dollars, as the market worries about the return on investment in AI infrastructure and the slowdown in data center construction.
