Highest temperature in Munich on July 12?

Platform comparison

Market context

The underlying event is the official daily high temperature recorded at Munich Airport Station on 12 July 2026, with the market currently pricing in a near-zero chance of any specific high-temperature bracket hitting. Historical data for Munich in July shows daily highs typically range between 22°C and 31°C, rarely exceeding 33°C, while Germany’s national record sits at 42.6°C[1][6]. The crowd-implied probability of 0% YES suggests the consensus believes the temperature will fall outside the specific range offered, likely clustering around the average 28–30°C band rather than extreme outliers.

Value may sit in contrarian positions if forecast models shift toward a heatwave, as Bavaria has seen maximum July temperatures reach 25.6°C in recent years with occasional spikes higher[7]. Traders should monitor the German Weather Service (DWD) forecasts for the coming days, particularly any announcements of sustained high-pressure systems or heatwave warnings, which have previously driven temperatures toward 40°C+ in Germany[9]. With settlement ending at 12:00 UTC on 12 July, the final resolution hinges on real-time Wunderground data for EDDM, making short-term forecast updates the primary catalyst for probability swings.

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

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 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.
