Highest temperature in Seoul on July 1?

Platform comparison

Market context

On 1 July 2026, the highest temperature recorded at Incheon International Airport will determine the outcome of a prediction market focused on Seoul’s peak heat, with the settlement window closing at noon UTC. Current crowd-implied probability for a “YES” outcome sits at 0%, yet trading data reveals a more nuanced picture: the market assigns a 38% chance to 30°C and 32% to 29°C, indicating strong belief that temperatures will reach at least the high 20s[1]. This divergence between the binary “YES” probability and the granular temperature distribution suggests traders are pricing in specific heat thresholds rather than a simple pass/fail condition.

Historical July records in South Korea show that extreme heat is not uncommon; Incheon recently hit 35.6°C in early July, and the national record stands at 41°C[8]. Comparable cases from the past decade confirm that temperatures regularly exceed 30°C during this period, making the 0% binary probability appear inconsistent with climatic trends. Traders should monitor daily weather bulletins from the Korea Meteorological Administration, particularly updates on cloud cover, wind direction, and precipitation probability, as these factors directly influence peak temperatures[7]. Any sudden shift toward clear skies or reduced wind could act as a catalyst for a rapid repricing of the market.

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.

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'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.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
