On Nov 5, 2026, two days after Democrats won Congress and key data-centre governorships, the Nasdaq 100 fell 6%, losing a record $2.3T, and the Philadelphia semiconductor index fell 12% (Bloomberg); on Nov 6 Taiwan's Taiex had its steepest-ever point fall, the Kospi fell 8.7% with trading halted, and the Nikkei 6.7%. The White House blamed 'Dumocrats'.
