This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 6 Jul '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=LTFM To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.

Prediction market odds reflect the aggregated beliefs of traders with real money at stake, often diverging meaningfully from traditional meteorologist forecasts. While weather analysts rely on numerical models and historical patterns, this market prices in trader conviction, which can incorporate local knowledge, recent data updates, or contrarian views. Comparing the market's implied probability to official forecasts from Turkish meteorological services or international weather agencies reveals whether traders are more bullish or bearish on heat. These differences highlight how decentralized markets sometimes anticipate shifts that institutional forecasters lag on, though both sources remain valuable for forming a complete picture.
This market resolves around Jul 6, 2026, once the highest temperature recorded in Istanbul on July 6 is confirmed and verifiable from credible public sources. The outcome is determined by the actual peak temperature reading from official meteorological stations or widely recognized weather data providers. Traders who correctly predicted the temperature range or threshold will receive their winnings, while incorrect positions expire worthless. Resolution typically occurs within hours of the close of the trading day, allowing rapid settlement once the data is finalized.
Major weather pattern shifts, updated seasonal forecasts, or anomalous atmospheric conditions could significantly reprrice this market. Heat waves, monsoon activity, or unexpected jet stream changes in the Eastern Mediterranean region would trigger trader repositioning. Real-time satellite imagery, humidity levels, and pressure systems also influence short-term expectations. Media coverage of extreme weather elsewhere in Europe or Asia may shift sentiment about regional heat risk. As July approaches, each new official forecast update or historical temperature comparison will likely spark trading activity, making this an active market for weather-focused traders and hedgers.
