Highest temperature in Munich on July 9?

Platform comparison

Market context

On 9 July 2026, Munich Airport will experience its daily peak temperature, a real-world metric that determines whether the market resolves to a specific Celsius bracket. Historical data frames this event: July highs at Munich International Airport typically range from 72°F to 75°F (22–24°C), rarely exceeding 87°F (31°C) or falling below 61°F (16°C)[1]. The hottest day ever recorded in Munich reached approximately 38°C, though recent summers show 34–36°C becoming common[7]. With the current crowd-implied probability for a high-temperature outcome sitting at 0% YES, the consensus assumes a standard summer day, yet value may exist if traders anticipate a heatwave anomaly similar to Germany’s record-breaking 41.3°C event in June 2026[4].

Traders must monitor the progression of high-pressure systems, particularly the movement of hot air masses like "Yvonne," which previously drove temperatures beyond 40°C across Europe[6]. The primary catalyst is the daily forecast from European and global models, which currently place Munich’s July maximum near 25–27°C for adjacent dates, suggesting a tight probability split[3]. While the market frontrunner is 25°C at 59%, with 26°C at 46%, contrarian angles could emerge if a sudden heat surge pushes the daily high into the 28°C bracket, a scenario some lines.com traders are already pricing in[2][9]. The settlement window closes at 12:00 UTC on 9 July, making real-time Wunderground data the definitive resolution source for the official daily high.

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.
