This market tracks the highest temperature recorded in San Antonio on July 6, 2026, using official National Weather Service data from San Antonio. The outcome will be determined by the maximum temperature reading on that specific date.
Resolution is based on the maximum temperature recorded at San Antonio on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 92°F or below, 93-94°F, 95-96°F, 97-98°F, 99-100°F, and 101°F or above. Each range corresponds to a distinct outcome. Official data must be obtained from the NWS Climatological Report via the specified URL, selecting San Antonio with Daily Climate Report. While preliminary NWS data and third-party weather sources may provide guidance, the final determination uses only the official NWS Climatological Report (Daily) value. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect the final reading.
Prediction market odds reflect real-money trader conviction and often incorporate meteorological forecasts, historical temperature patterns, and climate models in a single price signal. Unlike traditional analyst forecasts, which may represent a single institution's view, this market aggregates diverse trader perspectives into a dynamic probability. When meteorologists issue seasonal outlooks or near-term forecasts for South Texas heat, traders incorporate that data into their bids and asks. The market price typically converges toward consensus as the event date approaches and new weather data emerges, creating a continuously updated alternative to static analyst predictions.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract represents a specific temperature range or threshold, and the price of each contract reflects the market's implied probability of that outcome occurring. As new weather data, seasonal patterns, or climate signals emerge, traders adjust their positions, moving prices up or down. The spread between bid and ask prices narrows as the event date approaches and uncertainty decreases, allowing you to enter or exit positions at transparent, market-determined rates.
This market resolves around Jul 7, 2026, once the highest temperature recorded in San Antonio on July 6, 2026 is verified against credible public sources. The outcome is determined by the official temperature reading for that day, confirmed through established meteorological reporting. Once the event occurs and the data is publicly available and verifiable, the market settles according to which outcome bracket or threshold the actual temperature falls into. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless.
Major weather pattern shifts, seasonal climate forecasts, and long-range meteorological models will drive significant price movement in this market. El Niño or La Niña conditions, upper-atmosphere pressure systems, and historical heat-wave patterns for South Texas in early July all influence trader expectations. As summer approaches, updated seasonal outlooks from the National Weather Service or other climate agencies can shift the market substantially. Closer to July 6, short-range forecasts become more precise, typically narrowing the range of outcomes and concentrating trading activity. Unusual global climate events or regional drought conditions may also prompt traders to reassess their positions.
