Taiwan and South Korea are moving up the global stock-market rankings at historic speed as AI-linked semiconductor stocks pull trillions of dollars into Asian equity markets.
The Kobeissi Letter flagged the shift in a post on X, saying Taiwan’s total stock-market capitalization has reached a record $4.5 trillion, surpassing Canada for the first time and overtaking the UK two weeks earlier. The same post placed South Korea’s market capitalization near a record $4.1 trillion after it overtook the UK, with Canada now within reach.
The Taiwan milestone is backed by broader market data. Taiwan-listed companies recently reached about $4.47 trillion in total market capitalization, compared with roughly $4.44 trillion for Canada, according to Bloomberg data cited by Economic Times. TSMC has become the main engine, with its market value rising to about $1.8 trillion as demand for AI chips, advanced packaging, and high-end manufacturing capacity keeps expanding.
South Korea is moving along the same path. MarketWatch reported that South Korea became the world’s eighth-largest stock market after the Kospi surged 31% in April, its second-best month ever. Korean-listed companies reached about $4.2 trillion in market value, compared with roughly $3.9 trillion for the UK.
AI Hardware Is Driving The Re-Ranking
This is not a normal regional rotation. It is an AI hardware re-ranking of global capital markets.
Taiwan’s rise is dominated by TSMC, the foundry behind the most advanced chips used by Nvidia, Apple, AMD, and other major technology firms. South Korea’s surge is led by memory and AI infrastructure names, especially SK Hynix and Samsung Electronics. Reuters reported that SK Hynix jumped 13% to a record high after major U.S. technology companies signaled stronger AI spending, while South Korea’s broader market rose 5.1%.
The spending cycle behind the move remains enormous. Microsoft, Amazon, Alphabet, Meta, and other hyperscalers are still guiding toward hundreds of billions of dollars in AI-related capital expenditure, with data centers, GPUs, high-bandwidth memory, networking, power and cooling all becoming part of the same investment chain. A recent Big Tech AI capex update showed why that spending now matters for both equity markets and the broader risk trade.
The result is a geographic shift in market leadership. AI is not only lifting U.S. mega-cap tech. It is also repricing the markets that sit closest to the physical supply chain: chip fabrication in Taiwan and high-bandwidth memory in South Korea.
Crypto Reads The Signal Through Risk Appetite
The direct crypto link is not that Taiwan or South Korea’s stock markets automatically lift Bitcoin. The link runs through liquidity, risk appetite, AI narratives, and demand for high-beta assets.
When AI equities rise this aggressively, investors become more willing to price future growth, infrastructure spending, and long-duration technology exposure. That can support crypto when liquidity is loose, especially for Bitcoin, Ethereum, AI tokens, DePIN projects, and compute-linked narratives. A broader AI spending and market-structure story already showed how AI has become one of the dominant forces in global capital allocation.
The risk is concentration. Taiwan’s market is heavily tied to TSMC, while South Korea’s latest rally leans hard on SK Hynix, Samsung and other AI-sensitive companies. If AI capex expectations keep rising, the two markets can keep gaining share in global rankings. If hyperscaler spending slows or chip margins disappoint, the same concentration can turn into a volatility channel that hits Asian equities first and high-beta crypto narratives soon after.
Taiwan and South Korea now sit at the center of the AI trade because they control critical parts of the hardware stack. That makes their record market-cap milestones more than a regional equity story. They show where investors believe the AI boom is becoming real revenue, real capacity and real supply-chain power.
