Highest temperature in Munich on July 17?

Platform comparison

Market context

Munich Airport is set to record its peak July 17 temperature for 2026, with the market currently pricing a 0% chance of the event resolving to any specific outcome, despite scientific consensus favouring mid-to-upper 20s Celsius readings driven by warm summer air masses and limited early cloud cover [1]. Historical patterns for mid-July in Bavaria typically see highs between 24°C and 28°C, making the current crowd-implied probability of 0% for any specific range appear statistically anomalous when compared to the leading 27°C outcome, which holds a 31% implied probability in parallel markets [1].

The consensus has heavily favoured 29°C at 57% implied probability in related venues, positioning it as the clear favourite over the 28°C underdog at 31% [1]. A contrarian angle suggests value may sit in the 27°C range if the warm air mass weakens or cloud cover increases later in the day, as current local conditions show Munich as mostly cloudy with temperatures around 16°C (61°F), potentially suppressing the peak [2]. Traders should monitor real-time updates from Wunderground for the Munich Airport Station (EDDM) as the settlement window closes at 12:00:00Z on 17 July 2026, watching for any sudden shifts in air mass intensity that could invalidate the 29°C favourite [1].

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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.

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 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.
