Global Semiconductor Stocks Plunge as AI Infrastructure Financing Scrutiny Intensifies

Original summary · What happened

Equity contracts tracking major benchmark indexes slipped on Thursday as a worldwide sell-off across artificial intelligence and semiconductor firms erased over $1 trillion in market capitalization from top sector names during the week. Key chipmakers including Nvidia, Advanced Micro Devices, and Micron dropped sharply in premarket action, while specialized infrastructure providers such as CoreWeave and Nebius experienced steep pullbacks. The retreat was accelerated by renewed attention on debt loads, elevated interest rates, and circular vendor-financing structures that support heavy computing buildouts across the broader ecosystem.

International suppliers absorbed heavy losses overnight, marked by severe declines in major Asian and European equipment manufacturers and memory producers including SK Hynix, Samsung Electronics, SoftBank Group, Advantest, and ASML. The contraction persisted despite Taiwan Semiconductor Manufacturing Company exceeding quarterly forecasts and posting record profits on strong artificial intelligence demand. Investor concern centered on whether capital-intensive cloud hosting operations can scale cash flows rapidly enough to support steep borrowing costs and aggressive computing hardware expenditure.
