Taiwan Stock Market Hits Record Highs on AI Surge

Taiwan's benchmark stock index, the Taiex, reached consecutive closing highs on June 2 and June 3, 2026, driven by a surge in AI-related investments and the introduction of new technology. On June 3, the index climbed 1.98 percent to 46,459.16 points, following a previous peak of 45,557.31 on June 2. This momentum was bolstered by an overnight rally in U.S. tech stocks and optimism surrounding remarks made by Nvidia CEO Jensen Huang at Computex Taipei.

Taiwan Semiconductor Manufacturing Co. led the rally, contributing 360 points to the June 3 gain and reaching a record share price of NT$2,380.00 after the debut of the NX1 AI chip for PCs. The chip was developed through a collaboration between Nvidia, TSMC, and MediaTek Inc. While semiconductor firms like ASE Technology Holding Co. and King Yuan Electronics saw gains, MediaTek experienced a slight dip as investors took profits.

Concurrent with these index peaks, Taiwan's total market capitalization surpassed US$5 trillion at the end of May 2026, with technology sectors comprising approximately 81.44% of the total. To sustain this growth, the Taiwan Stock Exchange is implementing the Power Up Plan 2.0 and the Taiwan Pristine Stock Index to attract high-growth firms. Nearly 40 companies are expected to apply for listing in 2026, including more than 15 from the AI supply chain.
