Highest temperature in Munich on July 17?

Platform comparison

Market context

Munich faces a mid-summer heat check on 17 July 2026, with the Munich Airport Station set to record the day’s peak temperature in degrees Celsius. The crowd currently assigns a 0% implied probability to the “YES” outcome, suggesting near-universal doubt that the temperature will hit the specific threshold required for that resolution, while the market favourite sits firmly at 29°C with a 57% implied probability, followed by 28°C at 31% [1].

Historical July peaks at Munich Airport typically cluster in the mid-to-upper 20s, driven by warm summer air masses and limited cloud cover early in the day, which aligns with the scientific consensus underpinning the 27°C, 28°C, and 29°C outcomes [1]. Current conditions show Munich as mostly cloudy with temperatures around 16°C (61°F), a significant drop from the expected highs and a potential contrarian signal if cloud cover breaks later [2]. Traders should watch for real-time updates on cloud dissipation and incoming warm air masses from the south, as these are the primary catalysts that could push temperatures toward the 28–29°C range. The settlement window closes at 12:00 UTC on 17 July 2026, meaning any late-morning heat spike will be decisive. Value may sit in the 28°C outcome if the market overweights the 29°C favourite, given the current cloud cover and cooler starting temperature.

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Who Will Win. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

Do I need to KYC for this market?

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

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
