Pronóstico: Highest temperature in Paris on July 23?

Platform comparison

Market context

Paris’s July peak temperature is usually set by a warm summer afternoon rather than an extreme heat spike, with average July highs around 27°C and typical daily highs rising through the month to about 25°C in the later part of July.[2][3] Historical Paris climate data also suggests that July afternoons most often sit in the mid-20s, with temperatures only rarely pushing far above 30°C, although heatwaves can lift individual days well beyond the usual range.[3][4] That makes the current 0% implied chance for anything other than the lowest band look inconsistent with the seasonal baseline if a full day still has time to develop.[2][3]

For traders, the main drivers are the afternoon warmth at Paris-Le Bourget Airport, not the city centre forecast headline, because the market settles on the highest temperature recorded at that station on the day.[1] The key watchpoints are whether forecasters call for clear skies, light winds and strong sunshine into the local afternoon, or whether cloud cover, showers or a sea-breeze effect cap the high before it reaches the next range. Wunderground’s daily history page is the official resolution source, so late updates to the station observation feed matter more than broad Paris forecasts.[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.

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.

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.
