This market will resolve to the temperature range that contains the highest temperature recorded at the Amsterdam Airport Schiphol Station in degrees Celsius on 2 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 Amsterdam Airport Schiphol Station, available here: https://www.wunderground.com/history/daily/nl/schiphol/EHAM. 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.
Prediction market odds reflect real-money bets from traders and often diverge from traditional weather analyst forecasts. While meteorologists issue deterministic forecasts based on atmospheric models, prediction markets aggregate diverse opinions and incentivize accuracy through financial stakes. For Amsterdam's June 2 high temperature, market odds may price in tail risks or consensus shifts that analysts have not yet fully incorporated. Comparing the two reveals where traders see value relative to official weather guidance.
On Polymarket, the highest temperature in Amsterdam on June 2 is priced through outcome shares that traders buy and sell. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each temperature bracket or specific degree outcome has its own contract, and the price of each share reflects the market's implied probability. As traders update their views based on weather models, seasonal patterns, and climate data, prices shift in real time. The spread between bid and ask prices indicates liquidity and trader conviction around different temperature scenarios.
The market resolves on Jun 2, 2026, after the highest temperature for June 2 in Amsterdam has been recorded. Resolution is determined by official meteorological data for that calendar day. The winning outcome is the temperature bracket or specific degree reading that matches the actual observed high. Traders should monitor the event date closely and confirm which official weather source will be used to settle the market.
Major weather pattern shifts, seasonal forecasts, and atmospheric indices like the North Atlantic Oscillation can move odds significantly. Updates to European weather models, especially those issued 7–14 days before June 2, often trigger repricing as traders refine their expectations. Unusual heat waves, cold fronts, or climate anomalies reported in the weeks leading up to the event will influence market sentiment. Real-time meteorological alerts and revisions to long-range forecasts are key catalysts for price movement.
