Taiwan's equity market capitalization eclipsing India's stems primarily from TSMC's foundry dominance in sub-5nm processes, as reflected in the company's 2025 annual report detailing 54% revenue from advanced nodes. This structural shift aligns with patterns in the U.S. CHIPS and Science Act of 2022, which prioritizes onshore advanced manufacturing while leaving offshore concentration intact in East Asia. Primary data from the Taiwan Stock Exchange shows TSMC comprising over 30% of total market value, contrasting with India's more diversified NSE listings across IT services and energy. From one perspective, supply-chain concentration accelerates capital inflows to specialized nodes amid AI demand; from another, it exposes vulnerabilities to regional disruptions as noted in U.S. Department of Commerce export control records. Secondary analyses often overlook how this mirrors historical precedents in resource-based economies where single-commodity dominance dictated valuation hierarchies. Official filings from both TSMC and the Taiwan Ministry of Economic Affairs underscore sustained capex exceeding $30 billion annually, sustaining the divergence.
