The artificial intelligence boom is triggering a significant realignment of global stock market rankings, with Taiwan and South Korea successively overtaking major European economies. According to compiled market data, the Taiwanese stock market's total valuation now approaches $4.3 trillion, having surpassed the United Kingdom, Europe's largest market, earlier this month. South Korea trails the UK by only about $140 billion. Over the past seven months, these two tech-heavy Asian markets have already surpassed Germany and France.
This shift is primarily driven by substantial share price gains from three core AI hardware suppliers: Taiwan Semiconductor Manufacturing Company, the world's largest contract chipmaker, alongside South Korea's leading memory manufacturers, Samsung Electronics and SK Hynix. In contrast, European equity markets carry a heavier weighting toward financial sector companies.
"The rapid ascent of Korea and Taiwan stems from the long-term mega-trend of 'semiconductors as the new oil,' where chips have become a critical input for economic activity, coupled with the recent price-insensitive investment frenzy around AI," stated a Fidelity International portfolio manager. This dynamic highlights the "oligopolistic nature of cutting-edge semiconductor manufacturing."
As AI technology develops and proliferates, Asia's central role in the global economy is strengthening further, even as concerns about tariff impacts and geopolitical tensions persist. Boosted by robust chip shipments, Taiwan's export order growth in March hit its fastest pace in 16 years, while South Korea's exports grew by over 40% for the second consecutive month.
Investors are increasingly recognizing Asia's pivotal role: TSMC, Samsung, and SK Hynix are viewed as essential suppliers to AI leader Nvidia. TSMC's shares have risen over 40% year-to-date, while the two Korean giants have each surged more than 80%. TSMC's current market capitalization stands at $1.8 trillion, placing it among the world's largest companies, and the combined valuation of the two Korean firms reaches $1.5 trillion. In comparison, ASML, Europe's largest chip equipment maker, holds a market cap smaller than any of these three Asian leaders. In fact, the combined market capitalization of all technology stocks within the Stoxx Europe 600 index is only about $1.4 trillion.
"This trend can largely be seen as a divergence between the tech and non-tech sectors," commented the Head of Greater China Equities at UBS Global Wealth Management. "While some European AI-related stocks have also posted strong gains this year, the impact is more pronounced in Korean and Taiwanese markets due to their higher weighting in technology stocks."
Despite the massive surge in stock market valuations for these Asian chip powerhouses, their economies remain considerably smaller than major European nations. The International Monetary Fund projects South Korea's GDP for this year at $1.9 trillion and Taiwan's at $977 billion, far below the projected figures exceeding $3 trillion each for Germany, the UK, and France.
Naturally, given the high weighting of tech stocks in Asian market indices, some investors have raised concerns about excessive concentration. Samsung and SK Hynix together account for 42% of South Korea's Kospi index benchmark, while TSMC alone holds a similar proportion in Taiwan's Taiex index.
However, as AI technology becomes increasingly integrated into daily life, demand for various hardware and applications is expanding, broadening the scope of AI investment. Stocks like MediaTek and Delta Electronics have risen, causing TSMC's index weighting to decline from recent highs.
"At the index level, Asia's AI story appears concentrated in a few leaders, but it is more diversified across the entire supply chain," noted a J.P. Morgan Asset Management specialist for emerging markets and Asia-Pacific investments. "While the leading companies are getting larger, investment opportunities are also expanding as AI capital expenditure continues to trickle down the supply chain."
After surpassing the UK, Taiwan's market capitalization is now approaching that of Canada, which has benefited from rising gold and other resource stocks. The next highest is India, though its market is facing pressure from rising energy prices and weakness in its banking and IT sectors.
Currently, Europe is gradually losing ground in the global market cap rankings due to its relative lack of technology stocks. "Europe's heavier focus on mature industries results in a slower trajectory for market cap growth," said a Franklin Templeton portfolio manager. "Korea, Taiwan, and the broader North Asia region have built durable advantages in innovation, talent, and manufacturing scale, particularly in key growth industries, which continues to attract global capital."
Beyond institutional funds, retail investors drawn by the AI stock rally are providing additional support to the strong momentum in Asian markets. South Korea is witnessing a resurgence of its famously coordinated individual "ant" traders, while retail participation is also rising in Taiwan.
"Across Asia, we are seeing domestic investors play an increasingly important role," stated an M&G Investments Asian equity portfolio manager, adding that from a long-term perspective, the growth in the market capitalizations of Taiwan and Korea appears "justified."
