Highest temperature in Munich on July 1?

Platform comparison

Market context

On 1 July 2026, the Munich Airport Station will record its highest temperature for the day, a real-world metric that determines the outcome of this prediction market. Today, Polymarket prices the contract for a YES outcome at 0%, implying the crowd believes the temperature will fall outside the specified range. This stark pricing sits against a backdrop of extreme historical heat in the region, where Munich previously reached 38°C during a deadly European heatwave in early July, with western Germany hitting 37°C and Cologne reaching 30°C by morning [1]. Such events, driven by high-pressure systems like "Yvonne" that pushed temperatures beyond 40°C in Geilenkirchen, suggest that July in Munich can indeed produce record-breaking highs, making the current 0% probability a bold contrarian stance [2].

Traders should monitor the immediate weather forecast for thundery showers and light winds currently affecting the airport, which may suppress temperatures to a high of just 21°C today [3]. The key catalyst is the arrival of cooler air from the north, which historically ended similar heatwaves by 4 July, dropping temperatures to 28°C [1]. While average July highs at Munich International typically range between 21°C and 24°C, with daily peaks rarely exceeding 27°C, the potential for sudden spikes remains if the high-pressure mass persists [4][9]. No specific announcements are pending, but the dependency on the Wunderground resolution source means any data gaps or sensor anomalies could alter the final settlement, requiring close attention to the hourly forecast updates for high-temperature warnings [5]. The on-chain mechanics, settled in USDC on Polygon via conditional tokens, will resolve once the settlement window closes on 1 July 2027, locking in the outcome based on the verified daily maximum.

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

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 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 Kalshi UK 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.
