Taiwan's stock market is now worth more than the United Kingdom's, according to recent Bloomberg data, in a shift driven almost entirely by the insatiable global appetite for AI chips. The island's listed companies carry a combined valuation of roughly $4.3 trillion, edging past Europe's largest equity market, despite Taiwan's economy being less than a quarter the size of the UK's. South Korea, powered by Samsung and SK hynix, is roughly $140 billion behind and closing fast.
As for Taiwan’s stock market constituents, TSMC makes up the bulk, with a market cap of approximately US$1.98 trillion, or 40% of Taiwan’s entire stock market value. No other major economy has this degree of single-company dependence. By comparison, Apple represents roughly 7% of the S&P 500.
