Taiwan overtakes UK stock market on AI chip boom

Source: ft.com

TL;DR

• Taiwan's stock market overtook the UK's in total value amid surging AI chip demand.
• Taiwanese equities hit $4.13tn on Thursday, ahead of UK's $4.09tn, per Bloomberg data.
• Surge driven by TSMC's dominance shows AI reshaping global market rankings.

The story at a glance

Taiwan's stock market surpassed the UK's total market capitalisation for the first time, becoming the world's seventh largest. The shift involves Taiwan's tech-heavy listings, led by TSMC, versus the UK's broader FTSE 100 firms. This is reported now after Thursday's milestone and TSMC's strong quarterly results. Taiwan's economy is far smaller at about $977bn versus UK's $4.3tn.[[1]](https://www.ft.com/content/4e647b69-f130-4864-944c-3b4c0fcb1dbc?syn-25a6b1a6=1)[[2]](https://www.bloomberg.com/news/articles/2026-04-16/ai-driven-demand-pushes-taiwan-s-market-cap-ahead-of-the-uk)

Key points

• Total value of Taiwan-listed companies reached $4.13tn (or $4.14tn as of Wednesday in some data), topping UK's $4.09tn based on Bloomberg figures for primary listings.[[1]](https://www.ft.com/content/4e647b69-f130-4864-944c-3b4c0fcb1dbc?syn-25a6b1a6=1)[[2]](https://www.bloomberg.com/news/articles/2026-04-16/ai-driven-demand-pushes-taiwan-s-market-cap-ahead-of-the-uk)
• TSMC accounts for over 40-45% of Taiwan's market value after record Q1 profits up 58% year-on-year and revenue beats, fuelling the Taiex index's 16-26.5% year-to-date rise.[[3]](https://www.thisismoney.co.uk/money/markets/article-15739863/Taiwan-stock-market-bigger-UKs-semiconductor-giant-TSMC-cashes-AI-boom.html)[[4]](https://www.linkedin.com/news/story/taiwan-edges-past-uk-stocks-7185564?utm_campaign=storylines_en&utm_source=rss)
• UK's FTSE 100 up just 6.1% year-to-date, lacking major AI exposure beyond firms like ASML.[[5]](https://www.mexc.co/news/1032557)
• Taiwan's Taiex recovered fully from recent geopolitical dips tied to Iran tensions, hitting record highs.[[6]](https://www.reddit.com/r/taiwan/comments/1smqccj/taiwan_market_cap_tops_4_trillion_on_ai_boom)

Details and context

The crossover highlights how AI demand for advanced semiconductors has concentrated investor flows into Taiwan's chip sector. TSMC, the top contract chipmaker, powers much of the global AI infrastructure via clients like Nvidia, with its shares up nearly a third this year.

Taiwan lacks the UK's economic scale but benefits from a narrow tech focus in a "supercycle," as one analyst put it. Europe trails in listed AI plays, leaving London vulnerable despite banks and energy giants like HSBC or AstraZeneca.[[4]](https://www.linkedin.com/news/story/taiwan-edges-past-uk-stocks-7185564?utm_campaign=storylines_en&utm_source=rss)

Data covers actively traded primary listings, so rankings can shift with exchange rates or inclusions.

Key quotes

• "The UK and most of Europe doesn't really have anything exposed to this tech supercycle in listed equities aside from ASML." — William Bratton, BNP Paribas, to Financial Times.[[4]](https://www.linkedin.com/news/story/taiwan-edges-past-uk-stocks-7185564?utm_campaign=storylines_en&utm_source=rss)

Why it matters

Global capital now prioritises AI growth over broader economic size, boosting tech hubs like Taiwan. Investors see clearer upside in semiconductors, while UK firms face slower gains from limited AI ties. Watch TSMC earnings, AI spending trends, and Taiex momentum amid any geopolitical flares.[[2]](https://www.bloomberg.com/news/articles/2026-04-16/ai-driven-demand-pushes-taiwan-s-market-cap-ahead-of-the-uk)
