Export Control Database tracks US semiconductor controls including Entity List and FDPR rule, chip equipment restrictions on ASML and Tokyo Electron, AI software limitations, quantum technology controls, and telecommunications restrictions including Huawei ban with immediate updates when new controls announced. Company Technology Exposure Mapping analyzes every tech holding for China revenue percentage, restricted technology dependence, alternative market availability, and domestic champion potential benefiting from controls. Technology Bloc Classification categorizes holdings into US ecosystem (NVIDIA, AMD, Intel, US cloud), China ecosystem (Huawei, Alibaba, Tencent, Chinese chip makers), Dual ecosystem (Samsung, TSMC serving both), and Neutral suppliers. Export Control Probability Model predicts next restrictions using national security rhetoric, technology timelines, prior patterns, and lobbying activity, currently flagging expanded cloud computing controls, AI model access restrictions, and quantum networking controls as high probability. Revenue Impact Calculator quantifies that US blocking all chip sales to China causes NVIDIA to lose $12B (30% of revenue), AMD $4B (15%), ASML €8B (25%). Alternative Market Opportunity identifies Chinese chip makers, Graphcore, and Cerebras gaining when NVIDIA is cut off. Technology Race Tracker monitors US versus China progress across chip manufacturing, AI models, quantum computing, 5G/6G, and batteries showing who's winning each race.
