Highest temperature in Munich on July 1?

Platform comparison

Market context

On 1 July 2026, the Munich Airport Station will record its highest temperature for the day, a real-world event that determines whether this prediction market resolves to YES or NO. Today, Polymarket prices the YES contract at 0%, implying the crowd believes Munich will not hit the temperature range required for a positive outcome. This pricing sits on the Polygon network, where conditional tokens are settled in USDC, reflecting a market that has already dismissed the likelihood of extreme heat in Bavaria for this specific date.

Historically, Munich’s July highs average around 24°C (75°F), rarely exceeding 30°C unless a major heatwave strikes, as seen in 2015 when Bavaria recorded 40.3°C before Germany’s all-time record of 41.7°C was set in 2022 [1][4]. While Europe has experienced record-breaking heat, such as the 40.5°C in Geilenkirchen in 2022, Munich’s location and typical summer patterns mean it often stays cooler than North Rhine-Westphalia [1]. The current 0% probability suggests traders view Munich as unlikely to match those extreme peaks, even as regional heatwaves intensify.

Traders should monitor the German Weather Service (DWD) forecasts for high-pressure systems like “Yvonne,” which have previously pushed temperatures beyond 40°C in Germany [1]. Key catalysts include official announcements of heatwave schedules and any updates from Wunderground, the designated resolution source for this market. If a sudden spike in regional temperatures occurs, the 0% pricing could shift rapidly, but until such a catalyst is confirmed, the market remains firmly sceptical of extreme heat in Munich on this date.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
