Taiwan Pulls Ahead of Korea in Global AI Market Trade
Taiwan and South Korea have both done well as investors look for companies connected to artificial intelligence.
Recently, Taiwan’s stock market has performed better than South Korea’s.
Taiwan has companies involved in many parts of making and supporting AI technology.
South Korea’s market depends more heavily on two major chipmakers, Samsung Electronics and SK Hynix.
Their shares fell after a long period of gains.
Some investors think Taiwan has a steadier path to growth.
Others believe AI will keep demand for South Korean memory chips strong.
Investors are watching to see which market benefits more as AI spending changes.
Taiwan’s Taiex outperformed South Korea’s Kospi by about 23 percentage points last quarter, its widest margin since the turn of the century.
The Taiex rose 72% in 2026, while the Kospi gained about 65%, placing them first and second among more than 90 indexes tracked by Bloomberg.
Investors favor Taiwan for its broader AI-related businesses, spanning chip design, manufacturing, packaging, networking and servers.
South Korea’s market is more concentrated in Samsung Electronics and SK Hynix, whose shares fell 19% to 33% in the three months through September.
Some analysts see Taiwan as better positioned, while others argue strong demand for high-bandwidth memory could support Korean chipmakers.
