Highest temperature in Munich on August 6?

Platform comparison

Market context

Polymarket is pricing this Munich Airport Station temperature contract at **0% YES** right now, so the chain is effectively saying the market sees no meaningful chance of a hot outlier by the settlement cut-off. On Polymarket, the position sits as **conditional tokens** on **Polygon** and settles in **USDC**, so the key question is not whether Munich is “warm”, but whether the day’s high at EDDM lands inside the specific Celsius band that resolves this market.

For context, Munich’s August climate is usually mid-20s Celsius by day, with a long-run average daily high around **24.7°C** and a record August high of **37.0°C** in the historical Munich dataset[1]. The August 6 line in that same record shows an average high of **25.4°C** and a historical daily record high of **35.3°C**, which matters because the market is about the *day’s maximum* at the airport station, not the city centre or the daily mean[1]. In other words, a 0% price is only sensible if traders think the relevant temperature band is too low to capture a normal August afternoon, or if the contract’s strike range is especially high.

The near-term catalysts are straightforward: the first usable Wunderground reading for Munich Airport on 6 August, then any late-day warming that pushes the maximum into a higher bracket before the settlement window closes at 12:00 UTC on 6 August. The resolution source is explicitly Wunderground’s daily history page for Munich Airport Station, so traders should watch that station rather than broader Munich forecasts or nearby-city headlines[2]. If forecasts from mainstream weather services continue to show a standard August pattern rather than a heat spike, the on-chain price is likely to stay pinned near zero; if a European heatwave pattern builds, the market can reprice quickly, even before the airport’s observed maximum is published.

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.

UK Frequently Asked Questions

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.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
