Nasdaq Plunges 5% to Worst Day in 18 Months as AI Regulation Concerns Weigh on Tech Stocks
Source Summary
The Nasdaq composite index fell as much as 5% on Thursday, marking its worst day in 18 months, as the tech-heavy index entered correction territory—more than 10% below its recent record high. The decline reflects growing expectations that the artificial intelligence industry will face stricter regulation following Democrats' success in this week's midterm elections. The index's largest one-day drop since April 2025, when former President Trump announced tariffs on US trading partners, signals widespread losses across Wall Street.
Why it matters
A 5% single-day decline in the Nasdaq, the largest in 18 months, signals significant market volatility and investor concern about potential regulatory constraints on the AI sector, which has been a major driver of recent market gains.
What remains uncertain
The source does not specify which regulatory measures Democrats may pursue or their likelihood of passage.
