This market tracks the lowest temperature recorded in Houston on July 10, 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 July 10, 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: 72°F or below, 73-74°F, 75-76°F, 77-78°F, 79-80°F, or 81°F and above.
Prediction market odds reflect the collective judgment of traders with real money at stake, often diverging from traditional weather analyst forecasts. While meteorologists rely on numerical models and historical patterns, this market aggregates dispersed information and incentivizes accuracy through financial reward. Traders may price in factors—such as climate patterns, seasonal trends, or emerging weather systems—that shift odds away from consensus forecasts weeks in advance. Comparing the market's implied probability to official forecasts from the National Weather Service or private meteorology firms can reveal where traders see asymmetric risk or opportunity.
On Kalshi, this market is priced through a continuous order-book mechanism 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. Each share represents a claim on the final payout if that outcome occurs, and prices fluctuate based on supply and demand. The market displays a spread between the best bid and ask, reflecting the cost of immediate execution. As new information emerges or trading volume shifts, prices adjust in real time, allowing you to enter or exit positions at market rates or place limit orders to wait for your target price.
This market resolves around Jul 11, 2026, after July 10, 2026 concludes and the lowest temperature for that day in Houston is finalized. The outcome is confirmed once the event is verifiable from credible public reporting. Traders holding shares in the correct temperature band or outcome receive their payout based on the final verified data. Until resolution, you can continue to trade your position, allowing you to lock in gains, cut losses, or adjust your exposure as new weather forecasts and real-time conditions emerge.
Major weather pattern shifts, tropical storm or hurricane activity in the Gulf of Mexico, and seasonal climate anomalies could significantly move this market. Updated long-range forecasts from the National Weather Service, changes in ocean temperatures, or atmospheric pressure systems developing weeks ahead may trigger repricing. As July 2026 approaches, daily weather model updates and real-time atmospheric data will become increasingly influential. Short-term catalysts include heat waves, cold fronts, or unusual jet-stream positioning. Trading volume and sentiment shifts among the prediction community can also amplify price swings, especially if new information challenges the prevailing consensus.
