This market tracks the highest temperature recorded in Washington DC on July 10, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for Washington-National, which provides the authoritative temperature measurement for the day.
Resolution is based on the maximum temperature recorded at Washington DC on July 10, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Washington-National. The temperature is divided into six ranges: 86°F or below, 87-88°F, 89-90°F, 91-92°F, 93-94°F, and 95°F or above. Each range corresponds to a separate market outcome. The official data source is accessed through the NWS Regional Headquarters website by navigating to the Observed Weather tab and selecting Washington-National with Daily Climate Report. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution rather than preliminary readings or third-party weather services.
Prediction market odds reflect the collective judgment of traders betting real money, whereas traditional weather forecasts rely on meteorological models and expert analysis. This market allows you to compare how traders price the likelihood of specific temperature outcomes against what climate analysts and the National Weather Service project for that date. Markets often incorporate late-breaking data and shifting conditions faster than static forecasts, though both sources have distinct strengths. Watching this market alongside official forecasts can reveal where consensus exists and where traders diverge from institutional predictions.
This market resolves around Jul 11, 2026, once the actual maximum temperature for July 10, 2026 is recorded and verified. The outcome is confirmed against credible public sources documenting the official high temperature in Washington DC for that day. Traders holding shares in the correct outcome bracket receive their payout, while incorrect positions expire worthless. The resolution process is automatic once the data becomes available, ensuring all participants see the same verified result.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can all influence trader positioning in this market. Significant heat waves or unusual atmospheric conditions reported in the weeks leading up to July 10 typically drive prices higher for warmer outcomes. Conversely, cooler-than-normal weather patterns or tropical systems could shift odds toward lower temperature brackets. Real-time updates from the National Weather Service and visible changes in jet stream patterns often trigger rapid repricing. News coverage of extreme weather elsewhere can also affect risk sentiment and trading volume.
