Prediction market odds on Polymarket reflect aggregated trader expectations and often incorporate meteorological forecasts from professional weather services. While analysts issue point estimates or ranges based on atmospheric models, prediction markets price in uncertainty and real-time information from many participants. Comparing the implied temperature distribution from market odds to consensus forecasts from Korea Meteorological Administration or international weather models can reveal whether traders are pricing in higher or lower temperatures than official predictions suggest.
On Polymarket, the highest temperature in Seoul on June 10 is priced through outcome contracts representing specific temperature ranges or thresholds. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, with its price reflecting the probability traders assign to that temperature occurring. Liquidity and spreads vary by outcome; popular ranges typically show tighter bid-ask spreads. Prices update continuously as new information arrives and traders adjust positions based on weather model updates and seasonal patterns.
The market resolves on Jun 10, 2026, after the highest temperature for June 10 in Seoul has been recorded. Resolution is determined by official temperature data from a designated meteorological source, typically the Korea Meteorological Administration or equivalent national weather authority.

Once the data is confirmed and published, the winning outcome contract is settled.
