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 window closes at midday UTC, meaning the final reading will capture the day's high before afternoon thunderstorm activity typically peaks in the region during late July.

Historical July data from O'Hare shows the airport regularly records highs between 82–88°F during the final week of the month, with extreme readings above 95°F occurring roughly once per decade. The all-time July record at O'Hare stands at 97°F, set in 1995. The 0% crowd probability suggests traders are pricing in a specific temperature threshold that falls outside typical late-July ranges for the station—likely either an unusually cool outcome or a heat-wave scenario that would require sustained high pressure and minimal cloud cover across the Great Lakes region.

The National Weather Service Chicago office publishes extended forecasts six to ten days ahead; traders should monitor updates from late July 2026 for upper-air patterns and any heat advisories issued for northern Illinois. Lake Michigan's influence moderates Chicago's summer extremes compared to inland locations, and any forecast shift toward dry continental air masses or tropical moisture advection will materially affect the probability of crossing temperature thresholds. Real-time satellite and model consensus from the GFS and NAM systems become reliable roughly 72 hours before the settlement date.

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.

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.

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.
