Highest temperature in Istanbul on July 27?

Platform comparison

Market context

Istanbul will experience summer heat on 27 July 2026, with the settlement depending on the highest temperature recorded at Istanbul Airport (LTFM) by NOAA meteorological instruments. The market currently shows 0% probability assigned to any outcome, suggesting either insufficient trader participation or uncertainty about which temperature band will materialise.

Historical July temperatures at Istanbul Airport typically range between 28°C and 35°C, with occasional peaks above 36°C during heat waves. Data from the Turkish State Meteorological Service indicates that July averages around 28–29°C for daily highs, though extreme heat events have pushed readings to 39°C in recent decades. The 2023 summer saw temperatures exceed 40°C across parts of Turkey, establishing a reference point for how volatile seasonal conditions have become. Traders assessing this market should consider that Mediterranean summer patterns have shifted, with heat domes becoming more frequent and intense than historical norms.

The critical dependency for this market is NOAA's publication schedule for Istanbul Airport weather data, which typically updates within 24 hours of observation. Traders should monitor Turkish meteorological forecasts in late July 2026 and any heat wave warnings issued by the Turkish State Meteorological Service in the weeks preceding the settlement date. Atmospheric pressure systems moving across the eastern Mediterranean in mid-to-late July will determine whether conditions favour typical summer temperatures or anomalous heat. The market cannot resolve until the first data point for 28 July appears in NOAA's system, creating a potential settlement delay if publication lags.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.
