Market context
The highest temperature recorded at Esenboğa International Airport on 2 July 2026 is the real-world event determining this market’s resolution, with current crowd-implied probability sitting at 0% for any outcome above the lowest range. On Polymarket, this contract trades on Polygon using USDC, where conditional tokens reflect tight clustering around 33–34°C, assigning a 99% implied probability to the 34°C outcome[1]. Yesterday’s market for 1 July showed a frontrunner of 31°C at 100% probability, indicating a rapid temperature rise into the second day of July[2].
Historical averages for Ankara in July suggest daytime maximums of 29°C, with daytime temperatures usually reaching 27°C under low heat and humidity[3]. However, recent forecasts show daily highs ranging from 81°F to 94°F (27°C to 34°C), with an average high of 89°F (32°C), aligning closely with the market’s current frontrunner[7]. The 2026 Ankara NATO summit, scheduled for 7–8 July, may influence local weather monitoring but does not directly alter temperature patterns for 2 July[6].
Traders should monitor announcements from the Turkish Meteorological General Directorate (MGM), which reported extreme temperatures peaking in Ankara on 2 July 2026[10]. July is Turkey’s driest month, with average rainfall of only 17mm, intensifying heat across most regions except the Black Sea coast[4]. The settlement window ends 12:00 UTC on 2 July 2026, and resolution relies solely on Wunderground data for Esenboğa Airport, making real-time station updates critical for accurate pricing.
