How a Korean IPO works: institutions bid first (the demand forecast), which sets the final offer price; then individuals subscribe for two days through the lead managers' brokerage accounts; shares start trading on the listing date.
Dates and prices can change until the final terms are filed. Not financial advice. · Updated Oct 18, 2026 · IPO calendar
