This event tracks the lowest temperature recorded in Houston on June 17, 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 17, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the CLIHOU database at the Houston office. The official data source is the NWS Daily Climate Report, not preliminary reports or third-party weather services. Temperature ranges are divided into six bands: 69°F or below, 70-71°F, 72-73°F, 74-75°F, 76-77°F, and 78°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution. Different cities update their climate reports at varying frequencies, so the latest available data for the specified date must be consulted.
Prediction market odds reflect real-money incentives for accuracy, often incorporating signals that traditional weather forecasts may lag in capturing. While meteorologists rely on atmospheric models and historical climate data, this market prices in trader conviction and incorporates diverse information sources in real time. Comparing odds here to published analyst forecasts reveals whether the crowd expects conditions warmer or cooler than consensus models suggest. As June 2026 approaches, divergences between market pricing and official forecasts can highlight where traders see edge or where uncertainty remains highest.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and offers on outcome shares. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome—representing a specific temperature range or threshold—has its own price, and the spread between buy and sell orders reflects market uncertainty. As traders update their views on Houston's weather, prices adjust in real time, with higher prices indicating greater perceived likelihood of that outcome occurring on the specified date.
This market resolves around Jun 18, 2026, once June 17, 2026 has passed and the lowest temperature recorded in Houston that day is verified. The outcome is confirmed against credible public sources documenting actual weather conditions. Traders holding shares in the correct outcome receive their payout based on the final verified temperature, making accuracy the sole determinant of profit or loss in this event.
Major climate patterns, seasonal forecasts, and long-range weather models will drive price movement in this market. El Niño or La Niña conditions, shifts in the jet stream, and tropical system activity in the Atlantic can all influence summer temperatures across the Gulf Coast. Additionally, updated seasonal outlooks from NOAA and other meteorological agencies may shift trader expectations. As June 2026 approaches, shorter-range forecasts become more reliable, typically triggering sharper price adjustments as uncertainty narrows and the actual weather window draws near.
