Market context
Busan’s official daytime peak for the day is being set by the thermometer at Gimhae International Airport, and the market will settle on the temperature band containing the single highest reading there on 6 August. That makes the first few forecast updates and any late-morning heating particularly important, because the result is determined by the day’s maximum rather than the average or the start-of-day temperature.
The 0% YES price sits well below Busan’s normal August profile, where climatology points to highs in the upper 20s to low 30s Celsius, and current forecast pages are already leaning towards a warm but not extreme outcome. Busan has also shown it can spike sharply in heat events: recent reporting noted 38.8°C at the city’s official observing point during a record-breaking South Korean heatwave, underlining that very high readings are possible when the synoptic setup locks in hot, humid air.[4][15][16]
What traders should watch is whether the forecast holds or weakens through the day as sea breeze, cloud cover and any afternoon showers either cap the maximum or leave the airport station exposed to stronger heating. Local coverage on 5 August said Busan was expected to reach about 33°C, noticeably below the record-tier outcomes seen in recent heatwaves, while broader South Korean reporting described severe regional heat and emergency warnings, which can still support upside if the hot pattern persists.[11][3]

FAQ
- 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.
- 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.
