Recent meteorological observations and forecast model runs from sources tracking Zhengzhou conditions point to a daily maximum of 26°C as the most likely outcome, underpinning the market's overwhelming 100% implied probability for that threshold. September climatology in the region typically features highs near 24–29°C amid transitional monsoon influences, with today's overcast skies, light winds, and moderate humidity around 60–80% limiting further warming. Official temperature records, rather than preliminary estimates, will determine resolution, and minor adjustments in final verified readings from monitoring stations could theoretically shift the result if they fall outside the 26°C mark.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 19 Sep '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=zhcc
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Recent meteorological observations and forecast model runs from sources tracking Zhengzhou conditions point to a daily maximum of 26°C as the most likely outcome, underpinning the market's overwhelming 100% implied probability for that threshold.
