Major tech stocks drop after US midterm elections raise AI concerns

Major technology and artificial intelligence stocks suffered a steep decline following the US midterm elections. BBC News reported that the sell-off occurred after Democratic election wins, following campaigns focused on slowing artificial intelligence growth. The tech-heavy Nasdaq composite stock index fell by more than 5.5 percent, erasing an estimated 2.5 trillion dollars in market capitalisation according to data from Dow Jones. [1]

Financial markets reacted sharply to the prospect of stricter government oversight. BBC News reported that investors fear tougher scrutiny regarding data centre construction and the wider artificial intelligence sector. Hundreds of billions of dollars in market value were wiped out across major firms, marking one of the worst single-day drops for key US stock indexes since 2025. [1]

The market reaction touches several industry leaders. Meta Platforms, an American multinational technology firm headquartered in Menlo Park, California, is among the dominant Big Tech companies. Meta operates major digital platforms including Facebook, Instagram, WhatsApp, Messenger, and Threads, relying heavily on its advertising network which generated 97.8 percent of its revenue in 2023.

The downturn follows recent volatility across the broader technology sector. As FTMQ Tech reported earlier, major US telecommunications shares dropped sharply in October 2026 after SpaceX acquired spectrum to expand its Starlink mobile service. During that previous drop, shares in T-Mobile, AT&T, and Verizon fell by 13.27 percent, 9.81 percent, and 8.75 percent, respectively. [3]
