NVIDIA and multiple semiconductor stocks saw sharp single-day pullbacks as markets began repricing AI infrastructure expansion amid policy scrutiny, power grid connection bottlenecks, and capital return horizons. The Philadelphia Semiconductor Index (SOX) dropped roughly 12.25%, affecting memory, cloud compute, and power equipment vendors. However, the sell-off reflects a valuation reassessment rather than an immediate collapse in shipments. The industry's focus is shifting from raw GPU procurement to unit economics such as performance per watt, total cost of ownership (TCO), and actual cluster utilization.
