Highest temperature in Munich on August 19?

Platform comparison

Market context

On 19 August 2026, the highest temperature recorded at Munich Airport Station will fall into one of several defined ranges measured in degrees Celsius. The market currently prices all temperature outcomes at 0% probability on Polygon, suggesting either a technical settlement issue or that traders have not yet engaged with this contract. Resolution depends on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from official highs.

Munich's August climate typically produces daily maxima between 24–28°C, though heat waves can push readings above 30°C. Historical August data from the airport station shows that temperatures exceeding 32°C occur roughly once per decade, whilst readings below 20°C are rare. The 2022 European heat wave saw Munich reach 35.2°C in mid-August, demonstrating that extreme outcomes, whilst uncommon, remain within the realm of possibility. Current seasonal forecasts and long-range models will become more reliable as summer 2026 approaches, allowing traders to calibrate their positions against climatological baselines.

Traders should monitor European weather pattern forecasts from mid-July onwards, particularly Atlantic ridge positioning and any developing heat domes over Central Europe. The German Meteorological Service (Deutscher Wetterdienst) publishes monthly outlooks that may signal anomalous warmth or coolness. Any significant deviation from the 30-year Munich August average of 27.5°C would shift conditional token valuations materially. Settlement occurs at 12:00 UTC on the resolution date, giving traders a final window to adjust exposure based on morning observations from the airport station.

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.

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.

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%.
