This market will resolve to the temperature range that contains the highest temperature recorded at the William P. Hobby Airport Station in degrees Fahrenheit on 25 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 William P. Hobby Airport Station, available here: https://www.wunderground.com/history/daily/us/tx/houston/KHOU. 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 Fahrenheit (eg, 21°F). 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-money incentives and crowd wisdom rather than single-model outputs. On this market, traders are betting on whether the high will stay at 81°F or below, or exceed that level. Meteorologists typically issue point forecasts or ranges based on atmospheric models, while prediction markets aggregate dispersed information through price discovery. Both approaches have merit: analysts excel at physics-based modeling, while markets capture uncertainty and tail risks that models may underweight or overlook.
This market resolves around Jun 25, 2026, once June 25 has passed and the actual high temperature in Houston can be verified. The outcome is determined by comparing the recorded peak temperature against the threshold specified in the market. Verification relies on credible public weather data sources that document the day's high. Once the event is confirmed, the market settles automatically and traders receive payouts based on which outcome occurred.
Several factors could shift odds in this market before Jun 25, 2026. Updated seasonal forecasts, atmospheric patterns, or climate anomalies reported by meteorologists may prompt traders to reassess their positions. Major weather systems—tropical systems, heat domes, or cold fronts—could alter expectations for the day's high. Real-time model runs closer to June 25 will likely trigger trading activity as forecasts become more precise. Social media discussion, news coverage of extreme weather, or shifts in long-range consensus could also influence trader sentiment and move prices.
