This market tracks the overnight low temperature in Houston on July 6, 2026. The outcome will be determined by the official National Weather Service daily climatological report for the Houston area, which records the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Houston on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily) accessible via the Houston NWS office. The official data source is the NWS Daily Climate Report for Houston-Hobby, TX, available through the specified NWS regional office portal. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source for resolution. While secondary sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) value is used for final determination.
Prediction market odds reflect real-money incentives, meaning traders who misjudge the outcome face direct financial loss. This differs from traditional analyst forecasts, which may carry institutional or reputational constraints but no direct personal stake. Markets often incorporate information faster than formal forecasts update, since traders can adjust positions instantly. However, both sources are valuable: analyst models bring domain expertise and historical data, while this market aggregates the collective judgment of participants betting their own capital on the outcome.
On Kalshi, this market is priced through an order-book mechanism where traders submit bids and asks for contracts tied to specific temperature ranges or thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each contract reflects the probability traders assign to that outcome occurring. As new information arrives—updated weather models, seasonal patterns, or real-time atmospheric data—traders adjust their positions, moving the odds. Your ability to buy or sell at any time means the market price continuously incorporates fresh signals about what the lowest temperature will be on that date.
This market resolves around Jul 7, 2026, once July 6, 2026 has passed and the lowest temperature for that day is verifiable from credible public sources. The outcome is determined by the actual recorded low temperature in Houston on that date, confirmed through official meteorological data. Traders' positions settle based on whether the final temperature falls within or outside the ranges they predicted. Resolution is automatic once the data is available and verified, ensuring all participants receive payouts according to their positions.
Major weather pattern shifts, updated seasonal forecasts, and climate anomalies can all drive significant price movement in this market. Long-range models released months before July 2026 may suggest warmer or cooler conditions, prompting traders to adjust bids. Real-time atmospheric data, jet stream positioning, and tropical activity closer to the date will trigger sharper repricing. Additionally, historical temperature records and El Niño or La Niña patterns influence trader expectations. Each new forecast update or meteorological development gives participants fresh information to reassess their positions.
