About this market

Final prediction market prices for "Will KOSPI (KS11) close above __ end of Q1?". 4500 last traded at 100%. Next is 4750 at 100%. $26K has traded across 9 outcomes on Polymarket. The market closed on Mar 31, 2026.

This market will resolve to "Yes" if the official closing price for the KOSPI Composite Index (^KS11) on the final trading day of the first quarter of 2026 is higher than the listed price. Otherwise, this market will resolve to "No". The first quarter of 2026 ends on March 31, 2026. The closing price for the final day of trading on or before this date will be used to resolve this market. If the final trading day of the quarter is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution. If no official closing price is published for that session (for example, due to a trading halt into the close, system issue, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source for this market is Yahoo Finance, specifically the KOSPI Composite Index (^KS11) "Close" prices available at https://finance.yahoo.com/quote/%5EKS11/history/, published under "Historical Data."

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
