Market context
On 2 July 2026, the Chongqing Jiangbei International Airport Station will record its peak temperature for the day, a critical metric in a city where July is historically the hottest month. Chongqing’s summer climate is notorious, with average highs around 33°C and extremes frequently reaching 44°C. The current 0% YES probability for a specific temperature range appears misaligned with this baseline, given that daytime temperatures in July typically span 32–37°C, and heatwaves have previously pushed readings above 40°C.
Historical data frames this market as highly volatile rather than improbable. In August 2025, a severe heatwave caused temperatures to top 40°C, prompting residents to seek shelter from the broiling conditions [8]. Such events are not anomalies; July consistently delivers the highest monthly averages, with daytime highs often hitting 99°F (37°C) [7]. The 0% probability likely reflects a narrow range definition rather than a genuine expectation of cool weather, as even average days exceed 30°C.
Traders should monitor real-time updates from Wunderground, the official resolution source, and watch for sudden shifts in local weather forecasts. AccuWeather’s July 2026 forecast indicates daily highs ranging from 84°F to 102°F (29–39°C), suggesting significant variability [4]. Any announcement of an incoming heatwave or cloud cover could rapidly alter the peak temperature, making live data essential. The settlement window ends 12:00 UTC on 2 July, so timely verification of the day’s maximum is crucial before the market closes.

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 are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- 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.
