Highest temperature in Istanbul on July 27?

Platform comparison

Market context

On 27 July 2026, Istanbul Airport will record its highest temperature for that day, with settlement determined by NOAA's meteorological station data measured in degrees Celsius. The market currently shows 0% implied probability, suggesting traders expect the actual reading to fall outside whichever temperature range this specific outcome represents.

Istanbul's July climate is characterised by consistent heat. Historical data from the airport station shows July daily highs typically range between 28–32°C, with occasional peaks above 33°C during heat waves. The city experienced a notable heat event in July 2023 when temperatures exceeded 35°C on multiple days. The 0% probability implies either that the settlement range is unusually narrow or positioned at an extreme tail of the distribution—well above or below typical July conditions. Comparable weather prediction markets on extreme temperatures often see near-zero probabilities when ranges are set at thresholds like 40°C or above, or conversely at unusually low values for midsummer Istanbul.

Traders should monitor Turkish meteorological forecasts and European weather models as July 2026 approaches, particularly any alerts from Turkey's state weather service regarding heat waves or unusual atmospheric patterns. The settlement depends entirely on NOAA's Istanbul Airport station recording the specific temperature threshold on that date; any station maintenance or data gaps could delay resolution. The market cannot settle until the first data point for 28 July is published, creating a brief settlement lag after the actual weather event occurs.

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.

Which sports markets are available?

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.

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.
