توقع: Highest temperature in Chicago on July 27?

Platform comparison

Market context

Chicago's peak temperature on 27 July 2026 will be measured at O'Hare International Airport, the official National Weather Service station for the metropolitan area. The settlement hinges on the single highest reading recorded across all hours of that calendar day, converted to Fahrenheit if necessary.

Historical July temperatures at O'Hare show considerable year-to-year variation. The station's all-time July record stands at 97°F, set in 1988, whilst July daily highs typically range between 78°F and 86°F depending on synoptic patterns. The 30-year normal high for late July sits around 82°F. Extreme heat events—those pushing above 95°F—occur roughly once every five to seven years during summer months, making them uncommon but not unprecedented. The 0% implied probability suggests traders are pricing in a scenario where the market's temperature ranges exclude all plausible outcomes, a technical artefact rather than a genuine weather forecast.

Traders should monitor the extended-range forecast issued by the National Weather Service and European Centre for Medium-Range Weather Forecasts (ECMWF) as July 2026 approaches. Persistent high-pressure systems or heat domes tracking into the Midwest would be the primary catalyst for above-normal temperatures. Conversely, a trough of low pressure or frontal passage could suppress highs significantly. The market settlement depends entirely on actual recorded data from O'Hare's instruments; no adjustments or alternative stations apply.

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.

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.
