Highest temperature in Madrid on June 29?

Platform comparison

Market context

The real-world event at hand is the daily high temperature recorded at Madrid-Barajas Airport on 29 June 2026, which will determine whether the market resolves to a specific temperature range. Current crowd-implied probability sits at 0% for the YES outcome, suggesting traders believe the temperature will fall outside the defined range. Historical data frames this low probability: June 2026 in Madrid has seen daily highs between 95°F and 102°F (35°C–39°C), with the average high at 99°F (37°C) [3]. The warmest day so far was 22 June, reaching 38.3°C [7], while the highest recorded temperature in Madrid for June remains 40.7°C on 28 June 2019 [9]. Given that 29 June is not typically the peak heat day—30 June holds the highest average at 31.8°C [6]—the 0% probability aligns with seasonal patterns.

Traders should monitor Wunderground’s real-time updates for the Adolfo Suárez Madrid-Barajas Airport Station, as this is the official resolution source [1]. Key catalysts include any sudden shifts in weather forecasts, such as unexpected heatwaves or cloud cover, which could alter the daily high. While no specific announcements are pending, the settlement window ends at 12:00 UTC on 29 June 2026, meaning the final reading must be captured before then. Recent reports of record heat in Spain, with temperatures exceeding 110°F (43°C) in some areas, highlight the volatility of this period [4]. However, Madrid’s typical June profile suggests a stable range, making the 0% probability a rational assessment based on current conditions and historical trends.

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.

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.

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.

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.
