Market context

Madrid’s maximum at Barajas is likely to be set by a normal summer heat build-up rather than any one-off shock, and the market resolves on the *highest* reading logged during the day rather than the midday snapshot. That matters because Madrid regularly reaches the low-to-mid 30s Celsius in July, with average July highs around 33°C and daily maxima often sitting in that band[7][18].

Recent context points to a hot but not exceptional setup. AccuWeather’s Madrid forecast for 31 July shows a high near 92–96°F, while a Spanish outlet cited 38°C for the city on the same date, which would be enough to push the airport station into the upper 30s if verified on the day[1][4][6]. The broader historical frame is that Madrid’s standout extremes are far above normal, with the city’s recent benchmark highs around 40.7°C, but July day-to-day outcomes are usually well below that level[11][16].

For traders, the main catalysts are the live airport observations through the afternoon and whether the urban forecast is translated into an airport reading. Barajas can run a little differently from central Madrid, so the key dependency is the actual Wunderground station trace, not the city forecast alone. The market’s 0% implied YES makes the obvious risk a very hot afternoon still being priced as impossible, so any late surge towards the upper 30s would be the only meaningful path to a non-zero outcome[12][14][20].

Methodology

Football-specific comparison page for Pronóstico: Highest temperature in Madrid on July 31?. Polymarket's live quote (Polygon order book) plus platform attributes for the three reference venues. Sports markets reward liquidity — Polymarket and Betfair are materially deeper than Kalshi (US-focused) or Manifold (play-money).

Resolution & payout

Sports markets typically settle on official final-whistle plus league confirmation. Polymarket uses UMA Optimistic Oracle with a source URL per contract — usually official league data feeds or ESPN/Soccerway. Two-hour dispute window, then smart-contract payout in USDC.

FAQ

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.
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.
