Taiwan Overtakes India as World's Fifth-Largest Stock Market, Powered by TSMC's AI Rally

Global cloud providers are increasing capital spending on AI data centers, boosting Taiwan’s foundry, advanced-packaging and server supply chains. TSMC accounts for more than 40% of the market’s value, making Taiwanese equities a key proxy for international investors seeking exposure to AI hardware. The International Monetary Fund estimates Taiwan’s 2026 GDP at $977 billion, yet its stock market has overtaken that of the UK, whose GDP is about $4.3 trillion, underscoring Taiwan’s industrial clout.

Data compiled by Bloomberg showed the combined market capitalization of Taiwan’s major listed companies had risen to $4.14 trillion, or about NT$131.6 trillion, as of April 15, 2026. That surpassed the UK’s roughly $4.09 trillion and lifted Taiwan to seventh place globally. The benchmark Taiex closed at a record 37,132.02 on April 16, up 409.88 points, while TSMC forecast full-year revenue growth of more than 30% in U.S. dollar terms.

Taiwan’s latest bull run has been led by TSMC and supply chains serving AI servers, advanced processes and components, reflecting how global AI infrastructure spending is translating into orders for Taiwanese manufacturers. The research team at the KGI Taiwan Select Five Fund expects AI applications to expand into smart factories and autonomous vehicles over the next 4 to 5 years. It sees inference-computing demand as a key driver of technology-sector growth, bringing TISA funds into focus.

Taiwan stocks rose 723.75 points intraday on April 15, 2026, reaching a high of 37,019.87 and crossing 37,000 for the first time. TSMC also set an intraday record of NT$2,095 per share. Eleven domestic equity funds with TISA share classes posted record net asset values, with seven returning more than 50% since the start of the year. By April 16, the combined market capitalization of listed and over-the-counter companies had reached $4.14 trillion, or more than NT$130 trillion.
