South Korea Surpasses India to Become World's Sixth-Largest Stock Market
South Korea's Equity Market Surges, Overtaking India's as World's Sixth Largest
South Korea's equity market has surpassed India's as the world's sixth largest, driven by a significant surge in chip heavyweights that are powering the global artificial intelligence buildout.
According to data compiled by Bloomberg, the total market capitalization of Korea-listed companies has soared 86% this year to $5 trillion, while India's has declined to $4.8 trillion.

The rapid growth of South Korea's equity market can be attributed to the dominance of chip heavyweights such as Samsung Electronics Co. and SK Hynix Inc., which have recently joined the $1 trillion valuation club. These companies have lifted the Kospi's 2026 gains to more than 100% through their leadership in AI memory chips.
India's Market Decline
In contrast, India's equity market has been dragged lower by a weakening rupee, record foreign outflows, and a lack of companies directly linked to the AI infrastructure. Despite this, India's $4.15 trillion economy remains among the fastest growing in the world, outpacing Seoul's $1.93 trillion gross domestic product, according to International Monetary Fund estimates.
