Nvidia, AMD, Micron fall as AI stock sell-off deepens
A global sell-off in artificial intelligence and semiconductor stocks has resulted in over $1 trillion in market capitalization losses within a single week. High-profile companies including Nvidia, AMD, Micron, SK Hynix, and Samsung saw significant declines as investors reacted to rising borrowing costs and hotter-than-expected U.S. inflation data. The downturn was further exacerbated by concerns regarding potential memory chip oversupply by 2029 and warnings from industry executives at Broadcom and Intel that financing could become a primary obstacle to AI expansion, potentially outpacing chip or electricity shortages as a constraint.
