AI Boom Lifts Taiwan Stock Market Above $4 Trillion, Past UK to Rank Seventh Globally

The United States, China, Japan and Hong Kong have traditionally led global stock-market capitalization rankings, while India long held fifth place on the strength of domestic demand and corporate growth. Taiwan has now surpassed India for the first time, largely because of TSMC's dominance in advanced manufacturing processes and the AI chip supply chain. The milestone also underscores the heavy concentration of Taiwan's market value in its leading semiconductor company.

Based on 2026 data, Taiwan's stock market has risen to fifth globally and trails South Korea by only about $100 billion in market value. TSMC shares have gained 45% this year, making the company the main driver of the index. Taiwan's Financial Supervisory Commission has also eased the cap on funds' investments in a single stock, further channeling capital toward TSMC and semiconductor shares.

TSMC’s advanced manufacturing technology and global demand for AI chips have made it the main force behind Taiwan’s stock market rally past 40,000 points. The Financial Supervisory Commission is also advancing the “TSMC clause,” which eases limits on ETFs’ holdings of a single stock. The change reduces regulatory obstacles for funds tracking large index heavyweights, making passive inflows an important source of market support.

TSMC shares recently reached a record high and are moving toward NT$2,330 apiece, helping the weighted index break above 40,000 points. The impact of ETF portfolio adjustments continues to build. The market will look to corporate fundamentals and earnings data due in May to gauge whether the rally fueled by AI enthusiasm and passive buying can continue.

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.
