Highest temperature in Toronto on July 9?

Platform comparison

Market context

The real-world event centres on the highest temperature recorded at Toronto Pearson International Airport on 9 July 2026, with the market currently implying a zero per cent chance of the temperature reaching the 26°C bracket. Historical data for July at this station shows daily highs averaging around 79°F (26.1°C), rarely dipping below 70°F (21.1°C) or exceeding 89°F (31.7°C), with the warmest average occurring on 20 July at 80°F (26.7°C) [3]. A recent heatwave in early July 2026 shattered records, pushing temperatures to 89°F (31.7°C) on 3 July, yet the market’s 33.5% implied probability for a similar 26°C outcome on 7 July suggests traders view this specific date as less likely to hit that threshold despite the broader seasonal warmth [1][9].

Traders should monitor the daily forecast updates from the National Weather Service for CYYZ, which recorded a high of 75°F (23.9°C) at 10:00 am on 9 July, alongside any sudden shifts in wind patterns or cloud cover that could suppress peak temperatures [8]. The settlement window ends at noon on 9 July 2026, creating a narrow trading window where real-time data from Wunderground will be the definitive resolution source, and any unexpected storm activity mentioned in recent meteorologist updates could drastically alter the outcome [4][7]. With the momentum composite currently bearish and the trend score just below neutral, the market appears to be pricing in a cooler-than-average day for this specific date, making the 26°C threshold a high-risk proposition for YES positions [1].

FAQ

When do sports markets resolve?

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.
