Pronóstico: Highest temperature in Paris on July 9?

Platform comparison

Market context

Paris is currently bracing for a severe, extended heatwave that has already pushed temperatures to 40°C in the southwest and is forecast to linger for at least twelve days. The Île-de-France region is expected to see peaks near 36°C this week, with northern areas likely experiencing highs between 35°C and 38°C as the heat dome intensifies. This immediate meteorological reality directly contradicts the crowd-implied 0% probability for a high temperature, suggesting the market is mispricing the imminent thermal conditions.

Historical data from July 2026 shows daily highs ranging from 73°F to 102°F, with an average of 83°F, while the recent June heatwave already set national records. The current 0% probability ignores the persistent nature of this event, which Météo-France states could last until after 14 July, making a temperature exceeding typical July averages highly probable. Traders should watch for official updates from Météo-France regarding the peak intensity expected on Sunday and Monday, as forecasts indicate temperatures may rise to between 37°C and 42°C by then. The lack of market adjustment to these specific, time-bound warnings represents a significant pricing inefficiency given the confirmed duration of the heatwave.

Methodology

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.

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.

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.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
