Highest temperature in Seoul on July 2?

Platform comparison

Market context

The real-world event is the peak daytime heat recorded at Incheon International Airport on 2 July 2026, which will determine the settlement of a prediction market currently assigning zero probability to any outcome above the lowest temperature bracket. Historical data for Seoul in July shows average highs clustering around 27–28°C, with midday temperatures often feeling like 34°C due to humidity exceeding 80% during the monsoon season [2][3]. While the market implies an extreme cold snap, comparable July 1 data saw a 30°C bracket surge to nearly 70% probability just hours before resolution, suggesting the current 0% pricing may be a misread of typical seasonal volatility rather than a forecast of freezing conditions [5].

Traders should monitor the Korea Meteorological Administration’s short-range forecasts, which indicate today’s high is 25°C but warn that daily highs can reach 31.9°C on the hottest July days [8][9]. The primary catalyst is the timing of the Jangma rainy season, which typically spans late June to mid-July and brings short, heavy downpours that can temporarily suppress peak temperatures before the sun re-emerges to create steamy, elevated heat [2]. Watch for official updates on whether the rain clears by midday, as clear skies combined with lingering moisture often drive temperatures toward the 28–32°C range cited in recent travel guides [4]. Any sudden shift in cloud cover or wind direction could invalidate the current zero-probability stance and trigger a rapid price correction toward the 28°C frontrunner seen in parallel markets [1].

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.

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.

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.
