Highest temperature in Munich on July 1?

Platform comparison

Market context

The underlying event is the highest temperature recorded at Munich Airport on 1 July 2026, measured in degrees Celsius and resolved via Wunderground data. This single-day metric determines the market outcome, with the settlement window closing at 12:00 UTC on 1 July 2026. The current crowd-implied probability for a specific outcome sits at 0%, yet the frontrunner in the market is 21°C at 35%, followed by 22°C at 28%, reflecting a collective view that moderate summer heat is most likely [1].

Historical July temperatures at Munich International Airport typically range from 72°F to 75°F (22°C to 24°C), rarely exceeding 87°F (31°C) [5]. Recent extreme events, such as the 2026 European heatwave, saw Munich reach 38°C on 4 July before cooler air arrived, indicating that while record-breaking highs are possible, they are not the norm for early July [3]. The 0% probability for the current frontrunner appears inconsistent with the market’s own 35% assignment to 21°C, suggesting a data lag or misalignment in the displayed odds rather than a genuine absence of expectation [1].

Traders should monitor the German Weather Service (DWD) forecasts for high-pressure systems like “Yvonne,” which previously drove temperatures beyond 40°C across western Germany [4]. Key catalysts include the timing of cooler air masses moving from the north, as seen in 2026 when temperatures dropped to 28°C after 4 July [3]. Programmatically, one would query Wunderground’s daily history endpoint for Munich Airport (EDDM) at 12:01 UTC on 1 July to fetch the resolution value, then execute conditional orders based on real-time DWD updates for heatwave intensity [2]. Recent reports confirm Germany recorded a probable 40.5°C in Geilenkirchen, reinforcing the need to watch for similar high-pressure anomalies in Bavaria [4].

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Review UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
