This market will resolve to the temperature range that contains the highest temperature recorded at the Malpensa Intl Airport Station in degrees Celsius on 7 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Malpensa Intl Airport Station, available here: https://www.wunderground.com/history/daily/it/milan/LIMC. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
On Polymarket, the highest temperature in Milan on June 7 is priced through outcome tokens representing specific temperature ranges or thresholds. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders buy and sell these tokens, with prices reflecting the implied probability of each outcome. The market uses an automated market maker or order-book mechanism to determine prices based on supply and demand. As new information emerges—such as updated seasonal forecasts or atmospheric patterns—prices adjust to reflect changing trader expectations about whether Milan will experience cooler or warmer conditions on that date.
The market resolves on Jun 7, 2026, after the highest temperature in Milan on June 7 has been recorded and verified. The outcome is determined by official temperature data from a designated meteorological source, typically the Italian national weather service or an internationally recognized weather station in Milan. Once the actual high temperature is confirmed, it is matched against the predefined outcome categories in the market, and winning positions are settled accordingly.
Major weather pattern shifts, including changes to jet stream positioning, high-pressure system development, or approaching cold fronts, can significantly move odds. Updated seasonal climate forecasts from meteorological agencies, historical temperature anomalies for early June in Milan, and real-time atmospheric data closer to the event date all influence trader positioning. Additionally, broader European heat waves or cold snaps, volcanic activity affecting solar radiation, and shifts in Atlantic or Mediterranean circulation patterns can alter expectations about Milan's temperature on June 7, causing market prices to adjust accordingly.
