Pronóstico: Highest temperature in Paris on July 5?

Platform comparison

Market context

The real-world event is a forecasted peak temperature at Paris-Le Bourget Airport on 5 July 2026, where current crowd-implied probability for a 30°C high sits at 0% YES, despite recent market data suggesting a 44.5% chance for that exact outcome[1]. Historical context from the 2026 European heatwaves shows France experiencing unprecedented warmth, with May 2026 recording its hottest day since records began at 37.8°C and June peaks reaching 40°C in some areas[4][5]. Recent Météo-France statements indicate a severe, extended heatwave with temperatures potentially rising to 42°C by Sunday, 19 June, and Monday possibly becoming one of the hottest days ever documented in the nation[4]. This pattern of extreme heat frames the current 0% probability as an outlier, given that adjacent temperature buckets (29°C, 31°C, 32°C) all count as NO, spreading probability mass across ten alternatives while the modal peak remains in the 29–31°C range[1].

Traders must watch the next Météo-France or ECMWF medium-range forecast update, as the market is highly sensitive to these 48-hour projections with only two days to resolution[1]. Recent news from Reuters confirms a significant heatwave impacting France, with forecasts indicating temperatures may rise to between 37 and 42 degrees Celsius by Sunday, 19 June, and Monday potentially being one of the hottest days ever recorded[4]. The momentum composite is cautiously bullish on YES, with a 3.0% uptick in the 1-hour price suggesting fresh capital flowing into the 30°C outcome as European forecasts narrow the likely peak range toward the low thirties[1]. Key dependencies include the official Wunderground reading for the Paris-Le Bourget station, which will resolve the market at 12:00 UTC on 5 July, and any sudden shifts in cloud cover or wind patterns that could alter the daily maximum temperature[1].

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.

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.

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.

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.
