The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Toronto Pearson Intl Airport Station, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.

Frequently asked questions

Prediction market odds on Polymarket reflect aggregated trader beliefs about Toronto's June 6 high temperature, often incorporating meteorological models and historical seasonal data. Traditional weather analysts and Environment Canada forecasts typically rely on deterministic models and expert interpretation. Prediction markets may diverge from official forecasts because traders price in uncertainty, tail risks, and real-time information updates. Markets can sometimes outperform static forecasts by incorporating diverse data sources and incentivizing accuracy through financial stakes. Comparing the two reveals whether traders are more bullish or bearish on extreme temperatures than official meteorological guidance suggests.

The market resolves on Jun 6, 2026, after the highest temperature in Toronto on June 6 has been recorded and verified. Resolution is determined by official temperature data for that date, typically sourced from Environment Canada or recognized meteorological authorities. The outcome is binary or categorical depending on the specific contract structure—for example, whether the high reaches a specified threshold or falls within a defined range. Once the actual temperature is confirmed, the market settles automatically and traders receive payouts based on their positions and the final result.

Several factors could shift market odds for Toronto's June 6 high temperature. Updated seasonal forecasts and long-range weather models from meteorological agencies may indicate warming or cooling trends. Major weather systems—such as high-pressure ridges or cold fronts—developing in the days before June 6 would trigger repricing. Historical temperature anomalies and climate patterns for early June in Toronto provide baseline expectations. Real-time atmospheric data, jet stream positioning, and solar activity can influence trader sentiment. As June 6 approaches, short-range forecasts become more reliable, typically causing prices to converge toward the expected outcome and reducing uncertainty in the market.
