Highest temperature in Munich on July 27?

Platform comparison

Market context

On 27 July 2026, Munich Airport Station will record its daily high temperature, which Wunderground will log as the settlement reference point for this market. The 0% crowd probability reflects the market's current state rather than any meteorological certainty; Polymarket prices this contract at the extreme edge because no single temperature range has accumulated meaningful USDC backing on Polygon's conditional token infrastructure. Traders holding YES positions in any specific temperature band are effectively shorting all other outcomes simultaneously through the market's binary structure.

Munich's July climate presents a constrained forecasting window. Historical data from the past two decades shows late-July highs clustering between 24°C and 28°C, with extremes reaching 30°C during heat waves and dipping to 22°C in cooler years. The 2019 European heat wave pushed Munich to 34.6°C in late June, though July typically runs cooler. Current seasonal patterns and the thirteen-month lead time before settlement mean long-range weather models carry substantial uncertainty; the German Meteorological Service (Deutscher Wetterdienst) will publish increasingly reliable forecasts only in early July 2026.

Traders should monitor European summer weather patterns and any developing heat dome systems in late June and early July 2026. The Atlantic Oscillation index and Mediterranean sea-surface temperatures will influence whether high-pressure systems establish over central Europe. Wunderground's historical data for Munich Airport Station remains the sole authoritative source, making data access and verification critical before settlement. The market's current pricing suggests limited participation rather than confidence in cooler outcomes.

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.

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 Polymarket Alternative UK. 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.

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 Polymarket Alternative UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
