AI boom ignites stock market rally

Richard Sanders, Phnom Penh

Taiwan’s stock market has surged past India’s to become the world’s fifth‑largest, propelled by a powerful wave of investment tied to the global artificial intelligence boom and the dominance of its semiconductor industry.

At the center of the rally is Taiwan Semiconductor Manufacturing Co. (TSMC), the world’s leading contract chipmaker and the backbone of the modern AI supply chain. Shares of TSMC have climbed about 46% this year, fueling a broader surge in Taiwan’s equity market and lifting the island’s global financial standing.

The rise reflects how deeply Taiwan has become embedded in the infrastructure powering artificial intelligence—from advanced data centers to cutting‑edge processors used by major tech firms worldwide. As demand for AI chips accelerates, investors have increasingly piled into companies linked to the sector, with TSMC leading the charge.

The chip giant’s market strength has had a gravitational pull on the entire Taiwanese market. With TSMC accounting for a substantial share of the Taiwan Stock Exchange’s total capitalization, its rally has effectively dragged the broader index upward, amplifying the impact of global enthusiasm for AI technologies.

Taiwan’s ascent past India in global market rankings underscores a wider shift in investor focus toward semiconductor manufacturing and AI infrastructure. While India’s market has grown rapidly in recent years on the back of domestic consumption and economic expansion, Taiwan’s fortunes are currently tied to a single, powerful theme: the explosive growth of artificial intelligence.

Analysts say the trend highlights both the opportunity and concentration risk in Taiwan’s market. The island’s economic and financial trajectory is now increasingly linked to the performance of its semiconductor sector, particularly TSMC’s ability to maintain its technological lead and meet the surging demand for advanced chips.

For now, the momentum remains firmly in Taiwan’s favor. As AI investment continues to surge globally, the companies producing the hardware that makes it possible—especially those in Taiwan—are reaping the rewards, pushing the island’s market deeper into the ranks of the world’s financial heavyweights.
