This market tracks the lowest overnight temperature recorded in Houston on July 5, 2026. Resolution uses the official National Weather Service Climatological Report (Daily) for Houston-Hobby Airport, which may differ from other weather sources due to measurement methodology and rounding conventions.
Resolution is determined by the minimum temperature recorded at Houston-Hobby on July 5, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Houston NWS office. The official temperature is divided into six ranges: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, and 80°F or above. Each range corresponds to a separate market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the official final value from the NWS Climatological Report takes precedence over other weather sources such as AccuWeather or Google Weather.
Prediction market odds often diverge from traditional weather analyst forecasts because they incorporate real-time trader behavior and incentives. While meteorologists rely on atmospheric models and historical data, this market aggregates the distributed knowledge of participants with financial skin in the game. Traders may price in uncertainty, seasonal volatility, or emerging climate patterns differently than consensus forecasts. Comparing the two reveals where market participants see value or risk that official models may underweight, making prediction markets a complementary lens to conventional weather analysis.
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. The price of each outcome reflects the balance of buy and sell pressure, with shares trading between 0 and 100 cents based on perceived probability. As new information arrives—updated forecasts, seasonal data, or real-time conditions—traders adjust their positions, moving prices dynamically. This mechanism ensures prices stay responsive to changing expectations right up until market close.
This market resolves around Jul 6, 2026, after the lowest temperature in Houston on July 5, 2026 has been recorded and verified. The outcome is confirmed once credible public reporting of that day's minimum temperature becomes available. Traders' positions settle based on which outcome bracket or range the actual low temperature falls into, with payouts distributed accordingly. Resolution timing may shift slightly if official data requires additional verification, but the market will close and settle as soon as the temperature is reliably established.
Several factors could shift prices in this market over time. Seasonal climate patterns and long-range weather models updated closer to July 2026 will influence trader positioning. Major atmospheric events—such as heat waves, cold fronts, or unusual pressure systems affecting the Gulf Coast—could trigger repricing. Additionally, broader climate trends, historical temperature records for that date, and real-time forecasts issued in the days leading up to July 5 will all provide new information that traders incorporate. As the event date approaches, intraday weather updates typically drive the most volatile price movements.
