Highest temperature in Busan on June 19?

Prediction market odds aggregate the real-money bets of many traders, creating a decentralized forecast that often differs from traditional weather analyst predictions. While meteorologists rely on physics-based models and historical data, this market incorporates trader conviction through financial incentives—those who forecast accurately profit, while incorrect predictions cost money. Comparing the implied odds here to official forecasts from Korea Meteorological Administration or regional weather services can reveal where the crowd sees upside or downside risk. Markets often outperform single-model forecasts when traders have access to diverse information and skin in the game.

On Polymarket, traders set prices by buying and selling outcome shares in an automated market maker (AMM) system. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each temperature range has its own contract, and the price of each reflects the probability traders assign to that outcome occurring. As more capital flows into a particular range—say, 28–30°C—its price rises and others fall accordingly. The spread between bid and ask prices tightens as volume increases, rewarding active traders with better execution. Your entry and exit prices depend on the current state of the liquidity pool and the size of your trade.
