South Korean Stock Market Surpasses UK in Total Value, Climbing to 8th Largest Globally Amid AI Boom

Driven by the explosive rally in AI-related technology shares, South Korea’s stock market capitalization has officially overtaken that of the United Kingdom, securing its position as the world’s eighth-largest equity market.

 

Since the beginning of the year, the total market value of South Korean listed companies has surged by more than 45%, reaching $4.04 trillion.

 

In contrast, the UK’s market value grew by approximately 3%, totaling $3.99 trillion. This marks a dramatic shift from the end of 2024, when the UK market was nearly double the size of South Korea’s.

The AI Catalyst: Samsung and SK Hynix Lead the Charge

The meteoric rise of the South Korean market highlights a global investor preference for companies integral to the artificial intelligence ecosystem.

 

Shares of the country’s two largest listings, Samsung Electronics and SK Hynix, have skyrocketed, now accounting for over 40% of the benchmark KOSPI index’s total market capitalization.

 

Further momentum has been provided by President Lee Jae-myung’s market-oriented policies and corporate governance reforms, designed to boost valuations and enhance shareholder returns.

A Structural Shift in Asia-Pacific

South Korea’s trajectory mirrors that of Taiwan, which overtook the UK in April to become the world’s seventh-largest market.

 

Taiwan’s $4.48 trillion valuation is largely anchored by TSMC, which represents roughly 45% of its total market value and is now approaching the scale of the Canadian market.

 

"The rapid ascent of South Korea and Taiwan reflects a structural realignment of global equity markets driven by their dominance in AI hardware," said Francesco Chan, Investment Specialist at JPMorgan Asset Management. "

 

As the backbone of the AI supply chain, these regions are attracting sustained structural capital inflows due to their 'super-cycle' advantages in high-end foundries and memory chips."

Traditional Markets Lag Behind

While the UK remains Europe's largest equity market, its heavy reliance on traditional sectors—such as finance, consumer staples, energy, and mining—has caused it to lag behind AI-driven growth stories.

 

Patrick Kellenberger, Emerging Markets Equity Strategist at Lombard Odier, noted that factors like AI potential, global defense spending, and governance reforms are making Asian markets significantly more resilient than their European counterparts.

 

"Europe continues to face challenges in commercializing and scaling innovation," Kellenberger stated.

Wall Street Remains Bullish

Despite the market surge, South Korea’s GDP (estimated at $1.9 trillion) remains smaller than that of the UK, Germany, or France, all of which are expected to exceed $3 trillion this year.

 

However, Wall Street analysts remain optimistic about South Korean equities, citing attractive valuations and upward earnings revisions fueled by AI demand.

 

Goldman Sachs recently raised its target for the KOSPI index to 8,000, based on a forecast that corporate earnings could grow by more than 200% by 2026.
