South Korea Overtakes India To Become World's Sixth-Largest Stock Market On AI Chip Rally

South Korea has displaced India to claim sixth place in global stock market rankings, with its total market capitalisation climbing 86% this year to $5 trillion against India's $4.8 trillion, according to Bloomberg data.

The shift follows a similar move by Taiwan just days ago, when Taiwan Semiconductor Manufacturing Company’s (TSMC's) rally helped push that market ahead of India as well.

Together, South Korea and Taiwan have now emerged as the two biggest stock market winners of 2026, both riding the global race to build artificial intelligence (AI) infrastructure.

Two Companies Doing Most Of The Work

Samsung Electronics and SK Hynix, both major suppliers of memory chips used in AI systems and data centres, have been the primary engines behind South Korea's market surge. Both companies have recently crossed the $1 trillion market capitalisation mark, a milestone that has transformed investor sentiment toward the country.

South Korea's Kospi index has already blown past President Lee Jae Myung's earlier target of 5,000 points, with some Wall Street analysts now projecting even higher levels. The market has benefited from a combination of the AI investment boom and domestic corporate governance reforms pushed by the president, creating a powerful dual tailwind for investors.

Analysts opine the rally reflects the growing importance of South Korean technology companies in the next phase of global technological innovation and a broader shift in capital flows towards major Asian economies. But some market watchers have flagged concentration risk.

Samsung and SK Hynix have done most of the heavy lifting, according to analysts, and the long-term success of the rally will depend on whether South Korea can broaden investor confidence beyond a handful of large technology firms and follow through on genuine corporate governance reform.

Why India Has Fallen Behind

India’s market decline tells a different story. The country lacks major listed companies with direct exposure to the global AI infrastructure buildout, which has been the dominant investment theme of 2026. Additionally, a weakening rupee, rising energy costs, inflation concerns, slowing earnings growth and record foreign investor selling have compounded the pressure on Dalal Street.

Global funds have offloaded around $26 billion worth of Indian equities this year. India's benchmark indices are down about 11% in 2026, on course for their first annual fall after nearly a decade of gains.

According to analysts, India's growth story has lost momentum in investor minds as the country deals with domestic and external challenges, while longstanding infrastructure gaps continue to hold back its ambitions in advanced manufacturing.

Economy vs Market

Despite losing ground in stock market rankings, India's economic size remains far larger than South Korea's.

India's gross domestic product (GDP) stands at around $4.15 trillion against South Korea's $1.93 trillion, according to IMF estimates. I

India's GDP per capita has reached around $2,810 this year, still some distance from the $4,000 level that many investors associate with a significant upturn in domestic consumption.

According to analysts, India's long-term investment case remains intact, but inflation is creating near-term headwinds that are keeping global capital on the sidelines for now.
