This market tracks the highest temperature recorded in Houston on June 22, 2026. The outcome will be 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 maximum temperature recorded at Houston on June 22, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Climate portal for Houston-Hobby, TX. Temperature ranges are divided into six bands: 90°F or below, 91-92°F, 93-94°F, 95-96°F, 97-98°F, and 99°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS reporting may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather data sources.
Prediction market odds often diverge from traditional meteorologist forecasts because they incorporate real-time trader positioning, historical volatility, and broader economic or seasonal signals beyond standard weather models. While meteorologists rely on atmospheric physics and historical climate data, this market aggregates the financial incentives of many participants betting on the actual outcome. Comparing the implied probability here to published forecasts from the National Weather Service or private weather firms can reveal where the crowd sees edge or disagreement with official predictions.
On Kalshi, this market is priced through a continuous order book where traders submit bids and asks on outcome ranges or specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The platform matches buyers and sellers in real time, with the midpoint of the spread reflecting the market's consensus probability at any moment. As new information arrives—updated climate models, seasonal patterns, or historical precedent for that date—traders adjust their positions, causing prices to move and the implied temperature distribution to shift accordingly.
This market resolves around Jun 23, 2026, after June 22, 2026 has concluded and the day's highest temperature can be verified. The outcome is confirmed once the peak temperature reading is available from credible public sources, allowing the platform to settle all positions based on the actual observed high. Traders holding positions aligned with the verified temperature will receive payouts proportional to their stake and the final odds at which they entered.
Major signals include updated seasonal climate forecasts, historical temperature records for that date in Houston, and broader atmospheric patterns such as El Niño or La Niña conditions. Real-time weather model updates in the weeks and days leading up to June 22 will likely trigger sharp price moves as traders incorporate new data. Urban heat island effects, air quality alerts, or unusual jet stream positioning could also shift expectations, as could any anomalous heat waves or cold snaps in the months prior that reset baseline assumptions about summer temperatures in the region.
