Taiwan's stock market surpasses the UK's despite having less than a quarter of the UK's economy — AI boom propels Taiwan forward, TSMC alone accounts for more than 40% of Taiwan's total market value

Taiwan’s stock market has overtaken the UK’s, with listed companies valued at about $4.3 trillion.

The rally is being driven by AI-chip demand and TSMC’s outsized weight in the TAIEX.

Taiwan’s regulator loosened limits on fund exposure to large stocks, helping lift TSMC and the broader market.

TSMC also posted strong earnings, raised guidance, and expanded fab plans, reinforcing the boom.
