Kalshi
This event tracks whether Dallas/Fort Worth experiences prolonged periods of high temperatures during a specific week. It examines consecutive days where the average temperature exceeds a set threshold, reflecting potential heatwave conditions. The outcome depends on the duration of these hot periods throughout the specified dates.
These markets resolve based on consecutive days of average temperature above 90°F in Dallas/Fort Worth from August 31 to September 6, 2026, with varying minimum streak lengths from two to six days. For any market to resolve as Yes, the specified number of consecutive days must each have an average temperature strictly greater than 90°F, calculated as the arithmetic mean of hourly temperatures reported by The Weather Company from 12:00 AM to 11:59 PM local time, rounded to the nearest whole degree. An average of exactly 90°F does not count, and any day with fewer than 18 reported hourly values breaks the streak. Only days within the official period contribute to the streak, and data is locked at expiration time with no revisions allowed after that point.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders actively set the price through buying and selling contracts that represent the binary outcome — either the streak happens or it doesn’t. The current implied probability reflects the most recent trading activity and can shift quickly as new weather data, forecasts, or model updates emerge, especially in the weeks leading up to the event window.
This market resolves around Sep 8, 2026, with the outcome confirmed once official temperature readings from credible public meteorological sources are verified for the specified week. The final settlement will depend on whether the recorded average daily temperatures meet the threshold for each consecutive day in the defined period.
Key signals that could shift this market include updates from major weather forecasting services, sudden changes in long-range climate models, or the release of regional drought or heatwave alerts. Any significant deviation in predicted temperatures — whether warmer or cooler than earlier estimates — may cause rapid re-pricing as traders adjust their positions based on new expectations.
