Official measurements from Environment and Climate Change Canada placed Toronto’s highest temperature on September 2 at 28°C amid a day of variable cloud cover, southwest winds, and scattered thunderstorms that limited daytime heating. This reading aligns with model consensus and surface observations, producing the market’s 100% implied probability for that exact threshold. Trader consensus reflects the final verified data release, as prediction markets aggregate capital-backed assessments of official criteria rather than forecasts. A realistic challenge would require a post-publication correction from the primary reporting station or a shift in how the daily maximum is calculated across the network, though such revisions remain rare once initial quality-controlled values are confirmed.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 2 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=cyyz
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 which 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 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 measurements from Environment and Climate Change Canada placed Toronto’s highest temperature on September 2 at 28°C amid a day of variable cloud cover, southwest winds, and scattered thunderstorms that limited daytime heating.
