Market context
Warsaw's highest temperature on 27 July 2026 will be measured at Chopin Airport, the city's primary meteorological observation point. The settlement relies on Wunderground's historical weather database, which archives daily extremes from this station. The market currently shows 0% probability across all temperature ranges, suggesting either insufficient trader participation or genuine uncertainty about which bracket will contain the day's peak.
July temperatures in Warsaw typically peak between 20–28°C, with historical records showing occasional excursions above 30°C during heat waves. The city's warmest July days on record have reached 32–34°C, though such extremes occur irregularly. Comparable July 27 observations from prior years provide limited direct precedent, but the broader pattern of late-July weather in central Europe indicates that moderate warmth (22–26°C) represents the most frequent outcome, whilst genuinely hot days (above 28°C) require specific atmospheric conditions—high pressure systems and southerly airflow—that materialise perhaps once every few years.
Traders should monitor European weather forecasts from late July 2026, particularly outputs from ECMWF and national meteorological institutes, which typically provide reliable 10–14 day guidance by mid-July. Any significant heat wave developing across central Europe in that window would shift probability towards higher temperature brackets. Local factors including cloud cover, precipitation timing, and wind patterns on the day itself will determine the final reading, but these remain unknowable until the settlement window closes on 27 July at 12:00 UTC.

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.
- 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.
- 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.
