Market context
Busan’s highest temperature is being set against a live heatwave, after the city reached **38.8C** on 29 July, its hottest reading since modern records began in 1904. That makes the market’s current **0% YES** price look detached from recent extremes: Busan has already printed a far higher benchmark than the August climatology, and nearby southeastern Korea has pushed even further, with Yangsan hitting **42.5C** during the same spell.[1][2][16]
For framing, August in Busan is normally a warm, humid month, with typical highs around **30-31C** in forecast products and long-run August highs near **87F/30.5C** in climate summaries.[3][12][14] Against that baseline, the market only needs a day’s top reading to land in the relevant Celsius bucket, so the line is most sensitive to whether the current heat dome persists through the local afternoon maximum rather than to average monthly conditions. Recent reporting has already placed Busan in the high-30s during this outbreak, which is well above the norm and shows that a range break is not a remote tail event.[1][9][10]
Traders should watch the Korea Meteorological Administration and any updated local forecasts for Busan and nearby Ulsan or Yangsan, because short-term changes in cloud cover, sea breeze, or rainfall can suppress the day’s peak even when the broader pattern remains hot.[2][10][13] The settlement source is the Gimhae International Airport station on Wunderground, so the critical dependency is the airport’s recorded maximum, not the city average; that means inland readings, timing of afternoon convection, and whether the hottest hour coincides with a cleared sky all matter more than headline city temperatures.[16]

FAQ
- 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.
- 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.
- 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.
