Highest temperature in Toronto on July 15?

Platform comparison

Market context

Toronto Pearson International Airport is set to record its peak daily temperature for 15 July 2026, with the market currently pricing in a certainty that the reading will fall within the implied range. Historical data for mid-July at this location shows daily highs typically cluster around 26°C, rarely dipping below 21°C or exceeding 32°C [1]. The 100% YES probability suggests the market expects the temperature to land squarely within a narrow, high-confidence band consistent with these long-term averages, where extreme deviations are statistically uncommon for this specific date.

Traders should monitor real-time atmospheric conditions, particularly wind speed and humidity, which directly influence peak temperature readings. Current observations show wind speeds at 24 km/h from the west-north-west with humidity at 47%, factors that can either suppress or amplify heat depending on cloud cover and solar intensity [2]. While no specific weather alerts have been issued for Mississauga today, any sudden shift in pressure systems—currently falling at 998mb—could act as a catalyst for temperature variance before the settlement window closes at 12:00 UTC on 16 July. The resolution relies exclusively on Wunderground’s recorded maximum for the Pearson station, making minute-by-minute updates critical for validating the current pricing.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
