Pronóstico: Highest temperature in Munich on August 18?

Platform comparison

Market context

Polymarket has this contract pinned at 0% YES, which implies the market is effectively pricing out any outcome above the low-temperature bands. That sits alongside fresh weather runs for Munich Airport showing a cool, unsettled Tuesday: AccuWeather puts the day around 66°F with showers and cloud, while Time and Date shows roughly 69/57°F with a few thunderstorms and overcast conditions[6][13]. On the market’s own framing, settlement will follow the Daily Observations table for Munich Airport Station on Weather Underground, so the intraday peak matters more than the headline day-high figure.

For context, Munich in August usually sits closer to the low-20s Celsius, but the current setup is below that norm[14]. Comparable guidance around the current contract window has also leaned modest: Polymarket’s own event page cited ensemble guidance clustering the maximum near 19–20°C, with the leading implied prices concentrated on 19°C and 20°C rather than any warmer bracket[2]. That kind of distribution helps explain why the market can sit near a one-way view even before the day is over.

A trader would watch the timing of rain bands, cloud cover and any afternoon clearing, because those drive the day’s true high at the airport station more than the broad city forecast. The key dependency is the Weather Underground daily table at Munich Airport, not the summary day-high line, and revisions remain possible until the first datapoint for the following date is published[2]. With the settlement window ending at 12:00 UTC, the relevant print is the highest recorded by then, so late-morning observations are especially material.

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.
