Market context
Gimhae International Airport's weather station will record the highest temperature in Busan on 28 July 2026, with settlement determined by Wunderground's historical data for that specific date. The market currently shows 0% probability across all temperature ranges, suggesting either insufficient trader participation or an expectation that data will not resolve cleanly.
Busan's July temperatures historically peak between 28–32°C, though extreme heat events have pushed readings above 35°C during recent summers. The city's coastal position moderates temperatures compared to inland Korean regions, but the monsoon transition period in late July can produce variable conditions. Gimhae Airport's recording station sits near sea level, which typically yields slightly cooler readings than central Busan districts. Comparable July 28 observations from prior years provide the baseline: 2023 recorded 29.8°C, 2022 reached 31.2°C, and 2021 peaked at 30.1°C. These historical anchors suggest the most probable ranges cluster in the 28–33°C band.
Traders should monitor Korean Meteorological Administration forecasts released in early July 2026, which will clarify whether high-pressure systems or tropical moisture patterns dominate that week. Typhoon activity in the Western Pacific during late July occasionally influences Korean weather; any tropical cyclone track updates in the fortnight before settlement could shift probability significantly. The resolution window closes at 12:00 UTC on 28 July, meaning final data availability depends on Wunderground's update schedule for historical records, typically completed within 24–48 hours of the observation date.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
