This market tracks the lowest temperature recorded in Houston on June 25, 2026. The outcome is determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on specific temperature ranges.
Resolution is determined by the minimum temperature recorded at Houston-Hobby on June 25, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the Houston-Hobby, TX location on the NWS website. The official temperature measurement from this source is the sole determinant, regardless of preliminary reports or alternative weather services. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances that could affect interpretation of borderline temperatures.
Prediction market odds often diverge from traditional weather forecasts and analyst models because they incorporate real-time information, trader conviction, and market incentives absent from academic or institutional predictions. While meteorologists rely on physics-based models and historical data, this market reflects what informed traders are willing to stake financially on the outcome. Both approaches have merit: analysts provide detailed methodology, while prediction markets reveal aggregated belief weighted by financial commitment. Comparing the two can highlight where consensus breaks down or where market participants see value analysts may have missed.
On Kalshi, this market is priced through a continuous order book where traders submit bids and asks for shares tied to specific temperature ranges or outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects supply and demand; as more traders buy shares predicting a particular temperature band, that outcome's price rises, and vice versa. Settlement values are binary or range-based, meaning traders profit if their chosen outcome occurs by the resolution date. This mechanism ensures prices remain responsive to new information and trader conviction throughout the market's lifetime.
This market resolves around Jun 26, 2026, once the lowest temperature recorded in Houston on June 25, 2026 is verifiable from credible public sources. The outcome is determined by comparing actual meteorological data against the predefined temperature thresholds or ranges established at market creation. Traders who correctly predicted the temperature band or outcome receive their winnings, while incorrect positions expire worthless. Resolution typically occurs within hours or a day after the event, once official temperature readings are confirmed and published.
Major weather pattern shifts, seasonal forecasts, and climate anomalies can significantly move this market. Traders monitor long-range meteorological models, El Niño or La Niña conditions, and historical June temperature data for Houston to adjust their positions. Unexpected heat waves, cold fronts, or atmospheric blocking patterns in the weeks leading up to June 2026 would trigger repricing. Additionally, any revisions to climate normals or shifts in broader weather systems affecting the Gulf Coast region could prompt traders to reassess their forecasts and adjust market odds accordingly.
