Highest temperature in Munich on July 9?

Platform comparison

Market context

The underlying event is the official daily high temperature recorded at Munich Airport on 9 July 2026, measured in degrees Celsius and resolved via Wunderground data. Historical averages for Munich in July show daily highs typically ranging from 72°F to 75°F (22°C to 24°C), rarely falling below 61°F (16°C) or exceeding 87°F (31°C)[1]. Recent years have seen hotter spells, with Munich experiencing temperatures around 34–36°C becoming more common, and the hottest day ever recorded in the city reaching approximately 38°C[7]. Germany’s all-time record hit 41.3°C in June 2026, indicating a warming trend that could influence July extremes[5]. Given this context, a current crowd-implied probability of 0% for any specific outcome suggests the market may be mispricing the likelihood of moderate highs, as 25°C and 26°C remain statistically plausible based on both long-term averages and recent heat anomalies[2].

A power-user approaching this market programmatically would monitor real-time weather feeds from the Munich Airport station, cross-referencing with Wunderground’s hourly updates to detect deviations from the 22–24°C baseline. Key catalysts include regional heatwave announcements from the German Meteorological Service and any scheduled atmospheric pressure shifts that could elevate temperatures beyond the norm. Recent news confirms Germany is experiencing record heat, with forecasts suggesting highs up to 42°C in late June, which may persist into July[5]. Traders should also watch for cloud cover reductions and wind patterns, as east-northeasterly winds observed on 9 July 2026 could either suppress or amplify daytime highs depending on humidity levels[8]. Integrating these variables into a conditional order strategy allows for dynamic position adjustments as the settlement window closes on 12:00 UTC, 9 July 2026.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
