Taiwan becomes world’s fourth-largest stock market

Taiwan's benchmark Taiex index surged to fresh all-time highs this week, pushing the island's total stock market capitalization past $5.3 trillion and cementing its position as the fourth-largest equity market in the world, ahead of India, the United Kingdom, and South Korea.

AI-Fueled Rally Drives Historic Milestone

The Taiex rose 357.12 points, or 0.75 percent, to 48,157.29 on Wednesday, according to Focus Taiwan. The move extended a rally that saw the index hit a record intraday high of 48,601.53 on Tuesday, as reported by CNBC. According to data from MarketCapWatch cited by Focus Taiwan, the milestone pushed Taiwan's market capitalization to approximately $5.3 trillion, overtaking India's $4.94 trillion valuation.focustaiwan+1

Taiwan now trails only the United States ($82.7 trillion), China ($21.22 trillion), and Japan ($8.59 trillion) among global stock markets. The United Kingdom ranked sixth at $4.86 trillion, followed by South Korea at $4.5 trillion.focustaiwan

Semiconductors and TSMC at the Center

The rally has been powered by global demand for artificial intelligence infrastructure, with Taiwan Semiconductor Manufacturing Company ↘ 1.20% at its center. TSMC reported August 2026 consolidated net revenue of roughly $16.35 billion, up 53.3 percent year-over-year, outpacing its own full-year guidance of 40 percent growth. The chipmaker also raised its 2026 outlook earlier this year as AI and high-performance computing demand surged beyond expectations.247wallst+1

Taiwan's market capitalization first crossed the $5 trillion mark in May 2026, and the Taiex has now gained roughly 66 percent year-to-date after rising nearly 28 percent in 2025. A broader wave of AI optimism, including strong consumer adoption of Meta's ↗ 1.02% Muse AI agent, has lifted tech and semiconductor stocks across Asia.reuters+2

Global Tailwinds Add Momentum

The gains in Taiwan came amid a wider rally in Asian tech stocks. South Korea's Kospi rose 0.9 percent on Wednesday, with Samsung gaining nearly 1 percent. Reuters reported that memory and semiconductor stocks have "taken the leadership baton," recording a sixth consecutive day of gains.reuters

The prospect of easing geopolitical tensions also supported risk appetite, with oil prices declining for a sixth straight session and speculation growing around a possible extension of the U.S.-China trade truce as Chinese President Xi Jinping arrived in Washington.reuters
