Market context
Seoul's weather in mid-July sits firmly within the East Asian monsoon season, when the Korean peninsula experiences its most intense heat and humidity. The settlement relies on official readings from Incheon International Airport Station, which typically records daytime highs between 28–32°C during this period, though extreme heat events can push temperatures above 35°C. The 0% crowd probability suggests traders are pricing in a specific temperature threshold that historical data makes unlikely, rather than dismissing the possibility of heat altogether.
South Korea has experienced several notable heat waves in recent summers. July 2023 saw Seoul reach 33.1°C on the 18th, whilst the summer of 2022 brought multiple days exceeding 35°C across the peninsula. The Korea Meteorological Administration's records show that temperatures above 36°C on any given July day occur roughly once per decade in the Seoul region, making extreme outliers genuinely rare but not unprecedented. The current 0% reading likely reflects a market threshold set well above the seasonal norm—possibly 38°C or higher—rather than scepticism about typical summer heat.
Traders should monitor the Korea Meteorological Administration's 10-day forecasts as mid-July approaches, particularly any alerts for heat waves or tropical air mass intrusions. Upper-level atmospheric patterns, including the position of the Tibetan high-pressure system and any typhoon activity in the Western Pacific, will determine whether conditions remain seasonally typical or shift toward exceptional heat. The settlement window closes at 12:00 UTC on 18 July, meaning traders have no post-midnight data to influence final resolution.

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.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- 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.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- 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.
