How This List Is Built

The largest South Korean companies, ranked by market capitalization in US dollars with live prices — the market the KOSPI tracks.

Frequently Asked Questions

What counts as a South Korean stock here?: We classify each company by its headquarters country from its profile, so South Korean companies that trade in the US as ADRs still count toward South Korea. The list spans our global universe above a $2 billion market cap and refreshes nightly.
Is this the same as the KOSPI?: No. The KOSPI is a curated benchmark with licensed membership rules — free-float weighting, liquidity screens, periodic committee reviews. This list is the broader South Korea market those benchmarks draw from: every South Korean company we cover, ranked by market capitalization.
