Korean listed companies, ranked by market capitalisation

Market capitalisation — share price times shares outstanding — for every Korean listed company that files with the Financial Supervisory Service. Sorted highest first, as of the most recent close on file.

Why you can trust this number

Every figure is share price × shares outstanding on a single named date — not an estimate.
A company with no traded close on that date (delisted, halted, or newly listed after the cutoff) is left out, not shown as zero.
We do not rank a company as "undervalued" or "overvalued" from this number alone — that needs earnings and book value too. See the paired PBR ranking for that.
The full computation is open: build-rankings-json.mjs joins this from the same valuation tape used across every SeoulMarkets data page.

2,621 of 2,865 companies filed this figure — 244 did not, and are left out rather than shown as zero.

Frequently asked

What is market capitalisation?

The total value of a company’s outstanding shares — share price multiplied by the number of shares outstanding. It is a market price, not a measure of the company’s underlying worth.

Which is the largest listed company in Korea?

See the table above — it updates from the same source used across this site’s data pages, so the answer is whatever the most recent filing and closing price show, not a fixed claim.

Why do some companies have no market cap listed here?

A company is left off this ranking, not shown at zero, if it has no traded closing price on file for the date this page was built — for example a recent listing, a trading halt, or a delisting.
