This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Vnukovo International Airport in degrees Celsius on 15 Jun '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=UUWW To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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 often diverge from traditional weather forecasts because they reflect real-time trader sentiment rather than deterministic meteorological models. While meteorologists publish point estimates and confidence intervals based on atmospheric data, this market aggregates the collective judgment of participants who have financial incentive to forecast accurately. Comparing the implied probability from market prices to published analyst predictions can reveal where traders see asymmetric risk or where consensus forecasts may be underweighting tail outcomes.
On Polymarket, traders set prices through an automated market maker that converts contract odds into decimal or percentage form. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, with the current price reflecting the marginal trader's assessment of that scenario's likelihood. As new information emerges or traders adjust their views, prices adjust continuously, and the spread between bid and ask prices reflects market liquidity and conviction around specific temperature thresholds.
This market resolves around Jun 15, 2026, once the highest temperature recorded in Moscow on June 15 is verifiable from credible public sources. The outcome is determined by comparing the actual peak temperature reading against the contract thresholds traders have been betting on. Resolution occurs after the event concludes and official data becomes available, at which point winning positions are settled and losing positions expire worthless.
Major weather pattern shifts, updated seasonal forecasts, and atmospheric anomalies can significantly move this market. Unexpected heat waves, changes in jet stream positioning, or revised climate indices may prompt traders to reassess temperature probabilities. Additionally, real-time weather alerts, satellite data releases, and updates from meteorological agencies in the days leading up to June 15 can trigger rapid repricing. Even geopolitical or industrial events affecting regional air quality or urban heat dynamics could influence final trading activity.
