Highest temperature in Munich on July 1?

Platform comparison

Market context

On 1 July 2026, the Munich Airport Station will record its peak temperature for the day, a single real-world data point that determines the outcome of a weather prediction contract. Current crowd-implied probability for a “YES” outcome sits at 0%, suggesting the market believes the temperature will fall outside the implied range, while Polymarket’s frontrunner is 21°C at 77% probability, with 22°C next at 21%[2]. This stark divergence between the 0% crowd-implied probability and Polymarket’s 77% odds for 21°C highlights a meaningful cross-platform odds discrepancy that traders must scrutinise before committing capital[1].

Historical records show Munich’s July highs rarely dip below 21°C, with the city’s highest ever temperature reaching 37.0°C in August 2003 and 36.9°C in July 2015 and 2013[9]. Average July highs at Munich International Airport hover around 74°F (23.3°C), rarely falling below 61°F (16.1°C)[7]. The current 0% probability appears inconsistent with these baselines, especially given the recent European heatwave that pushed temperatures to 38°C in Munich on 1 July in a prior year, with overnight lows barely dropping below 24°C in hotspots across Germany[3][4].

Traders should monitor the German Weather Service’s (DWD) daily forecasts and Wunderground’s real-time updates for the Munich Airport Station, as these are the official resolution sources[2]. The heatwave is expected to shift eastward by the end of July, potentially cooling Central Europe and the Balkans, which could influence late-July conditions but not the 1 July peak[5]. No new announcements are pending, but the DWD’s Thursday forecast for France (37–42°C) and Germany’s record 41.3°C in Saarbruecken underscore the volatility of current weather patterns[4][6].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.

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 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 Best Prediction Markets 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.
