Highest temperature in Seoul on July 9?

Platform comparison

Market context

Seoul is set to experience its peak early-July heat on 9 July 2026, with the Incheon International Airport station likely to record temperatures near or above 37°C. Historical data shows that early July in the capital has already broken records, with Seoul hitting 37.7°C in 2025 and 37.8°C in 2026, the highest ever for this period since 1908[1][8]. These figures frame the current 0% crowd-implied probability as potentially misaligned, given that such extreme heat is not anomalous but increasingly typical for early July in the region.

Traders should monitor the monsoon window, which typically ends by mid-July, as a clear shift to dry, sunny conditions could trigger a rapid temperature spike. The Korea Meteorological Administration notes a 60% chance of slight rainfall today, but if skies clear by tomorrow, humidity combined with intense solar radiation may push temperatures beyond 34°C, creating a steamy, high-heat environment[2][5]. Watch for official weather bulletins from the KMA and real-time updates from Wunderground, as any delay in monsoon retreat could be the catalyst for a record-breaking day[2].

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.

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.

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.
