Official meteorological observations from the Netherlands' KNMI confirmed a daily maximum of 30°C in Amsterdam on August 9, aligning precisely with the market's 100% implied probability for that outcome. Clear skies and stable high-pressure conditions supported peak afternoon heating consistent with forecast model runs, while regional station data and climatological baselines for early August ruled out higher readings. This skin-in-the-game consensus reflects traders' access to verified post-event measurements rather than projections. Only a late data revision or station-specific anomaly could alter resolution, though such shifts remain unlikely given multiple confirming sources.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 9 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Amsterdam Airport Schiphol Station, available here: https://www.wunderground.com/history/daily/nl/schiphol/EHAM.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Official meteorological observations from the Netherlands' KNMI confirmed a daily maximum of 30°C in Amsterdam on August 9, aligning precisely with the market's 100% implied probability for that outcome.
