This market tracks the lowest temperature recorded in San Antonio on June 16, 2026. The outcome will be determined by the official National Weather Service daily climatological report for San Antonio, which provides the authoritative minimum temperature measurement for that date.
Resolution is based on the minimum temperature recorded at San Antonio on June 16, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website at the specified URL, selecting San Antonio with Daily Climate Report. The minimum temperature is divided into six ranges: 67°F or below, 68-69°F, 70-71°F, 72-73°F, 74-75°F, and 76°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 NWS Climatological Report (Daily) serves as the definitive source, superseding other weather services.
Prediction market odds reflect real-money trader conviction and aggregate dispersed information about June 16 weather conditions in San Antonio. Unlike traditional forecasts from meteorologists or climate models, which rely on historical data and atmospheric modeling, this market incorporates live expectations from participants with financial stakes in accuracy. Traders continuously update positions based on new weather reports, seasonal patterns, and atmospheric indicators. While analyst forecasts provide a single point estimate, market odds reveal the full distribution of possible outcomes and how confidence shifts as the event date approaches.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, and the price of a share reflects the implied probability that the lowest temperature will fall within that bracket. Traders profit by correctly predicting the actual low; those holding the winning outcome receive the full payout. Bid-ask spreads tighten as volume increases, making the market more efficient and easier to enter or exit positions near the event date.
This market resolves around Jun 17, 2026, once June 16, 2026 has passed and the lowest temperature recorded in San Antonio is verified. The outcome is confirmed against credible public sources reporting the official daily low. Traders holding shares in the outcome bracket that matches the verified temperature receive their payout, while other positions expire worthless. Resolution typically occurs within hours of the close of the trading day, allowing rapid settlement and payout distribution.
Several factors can shift odds in this market before resolution. Seasonal weather pattern updates, long-range forecasts from the National Weather Service, and historical temperature anomalies for mid-June in San Antonio all influence trader positioning. Major climate events or atmospheric patterns—such as cold fronts, high-pressure systems, or unusual jet-stream behavior—can trigger sharp repricing. As June 16 approaches, short-term forecasts become more reliable, typically narrowing the range of plausible outcomes and concentrating liquidity around the most likely temperature brackets.
