Wall Street’s AI Trade Cracks as Nasdaq Sinks 2.6%, Chipmakers Lead Rout
The S&P 500 fell 1.2% and the Nasdaq tumbled 2.6% Thursday as investors reassessed whether AI infrastructure spending will ever pay for itself — the semiconductor ETF dropped roughly 4% with Lam Research down about 9%, while money rotated into bonds and pushed the 10-year Treasury yield down 11 basis points to 5.02%. IBM’s own CEO is now publicly flagging that large enterprises are scrutinizing AI return on investment, which is the kind of admission that turns a pullback into a re-rating. Boards and CFOs with AI capex on the books should expect financing costs and investor patience to tighten in tandem from here, not independently.
