Highest temperature in Chengdu on July 27?

Platform comparison

Market context

Chengdu’s afternoon heat is the key driver here: current live weather shows 24°C with 74% humidity and a light west-south-westerly breeze, while near-term forecasts still point to a hot, humid day with highs around 35-37°C and a meaningful chance of showers or thunderstorms. In a city that typically sees July highs in the high 20s to mid-30s, a settlement anywhere in the upper 20s or low 30s would be consistent with normal summer conditions, but a reading near the forecast ceiling would require the heat to hold through the airport’s peak warming window.[1][2][4][5][6]

The 0% crowd-implied YES probability is best read against the market’s exact source and timing: it resolves on the highest temperature recorded at Chengdu Shuangliu International Airport Station on 27 July, not on the city-wide forecast headline or an average daily high. Traders should watch for whether the airport stays dry through late morning and early afternoon, because cloud cover and convective rain can suppress the day’s maximum even when the broader forecast looks hot; the opposite risk is a brief clear spell that allows a sharp spike before storms arrive. Weather forecasts for the day already include isolated thunderstorms and rain risk, so the main catalyst is the timing of any precipitation relative to the afternoon peak rather than the existence of heat itself.[2][4][5]

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.

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.

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.

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.
