This market tracks the lowest temperature recorded in Houston on June 26, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on which temperature range the recorded minimum falls into.
Resolution is determined by the minimum temperature recorded at Houston-Hobby on June 26, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Houston-Hobby, TX location on the NWS website. The official data source is the NWS Climatological Report rather than preliminary reports or third-party weather services. Temperature measurements may be subject to rounding and conversion nuances in preliminary NWS data, so traders should verify against the final official report. Each outcome corresponds to a specific temperature range: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, or 80°F and above.
Prediction market odds reflect real-money trader consensus and often diverge from traditional weather forecasts issued by meteorologists and government agencies. While meteorologists rely on physics-based models and historical climate data, this market aggregates the collective judgment of traders who face financial consequences for inaccuracy. Prediction markets can sometimes detect signals earlier than conventional forecasts, especially when new data emerges or when consensus shifts. However, both approaches have merit: analyst forecasts provide detailed reasoning, while market odds distill distributed knowledge into a single probability estimate.
On Kalshi, this market is priced through an order-book mechanism where buyers and sellers submit bids and asks for each temperature outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders compete to fill orders at their preferred price, and the last executed trade sets the current market price for each outcome bracket. Prices range from 0 to 100 cents, representing implied probability. As new information arrives—such as updated weather models or seasonal patterns—traders adjust their bids, causing prices to shift and reflecting the market's evolving assessment of the June 26 low temperature.
This market resolves around Jun 27, 2026, once the event has occurred and the outcome is verifiable from credible public sources. The winning outcome is determined by the actual lowest temperature recorded in Houston on June 26, 2026. Traders holding positions in the correct outcome bracket receive their payout, while incorrect positions expire worthless. Resolution typically occurs within hours of the market end time, once official temperature data is confirmed and published.
Several factors could shift odds significantly before resolution. Updated seasonal forecasts or climate pattern analyses may alter expectations for June temperatures in Houston. Major weather systems developing weeks or days before the event—such as cold fronts or unusual atmospheric conditions—could trigger sharp repricing. Long-range model consensus shifts, changes in solar activity predictions, or anomalies in ocean temperatures could also influence trader positioning. As June 26 approaches, real-time weather data and short-term forecasts will likely dominate price action, with the final days seeing the most volatile trading.
