Quick Summary

The S&P 500 experienced a significant drop of 4.4% on Thursday, marking its worst day since April 2025 when President Trump's "Liberation Day" tariffs caused market turmoil. This sell-off was primarily driven by declines in AI-related stocks due to concerns over potential restrictions on data center construction following Democratic victories in the U.S. midterm elections. Additionally, the Dow Jones Industrial Average fell more than 1,800 points and the Nasdaq Composite dropped 5.5%, while Canada's S&P/TSX Composite index declined by 2.03%.

Story summary

On November 5, 2026, stock futures and major indices in the US market dropped sharply following Democrats' unexpected victories in midterm elections, leading to fears of stricter AI regulation. The Dow Jones Industrial Average plunged by 1,200 points, while the tech-heavy Nasdaq Composite fell by up to 5% on concerns that an incoming Democratic Congress would impose new regulations on the artificial intelligence industry. This selloff erased over $2 trillion in market value from tech stocks within two days of the election results being announced. Major companies such as Nvidia, Intel, and SpaceX saw significant declines, with some investors caught off guard by the political shift.
