South Korea Overtakes India as World's Sixth-Largest Stock Market on AI Surge

What Happens Next

• →Passive and active global equity funds benchmarked to emerging-market and all-country indices increase South Korea weightings by 2-4 percentage points, channeling an estimated $15-30 billion in incremental flows into Korean semiconductor names within the next quarter.
• →Indian equity strategists and policymakers accelerate efforts to cultivate a domestic AI and semiconductor ecosystem — including fab subsidies and startup incentives — to counter the narrative of structural AI underexposure that now defines India's relative positioning.
• →Concentration risk in the Korean market intensifies as Samsung Electronics and SK Hynix account for an outsized share of Kospi's capitalization, making the index increasingly vulnerable to a single-sector correction tied to AI demand cycles.

Near-term: Global fund managers rebalance emerging-market portfolios toward South Korea, amplifying inflows into Samsung and SK Hynix and widening the capitalization gap with India over the next 1-3 months. Long-term: Over 2-5 years, global equity market rankings become increasingly correlated with national positioning in the AI supply chain, diminishing the influence of demographic and consumption-driven growth narratives that previously favored markets like India.
