This market tracks the lowest temperature recorded in San Antonio on July 6, 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 July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS website by navigating to the "Observed Weather" tab and selecting "San Antonio" with Daily Climate Report. The temperature is divided into six ranges: 70°F or below, 71-72°F, 73-74°F, 75-76°F, 77-78°F, and 79°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 rather than preliminary estimates or third-party weather services.
Prediction market odds reflect the collective judgment of traders betting real money, which often incorporates a wider range of information than traditional weather forecasts alone. While meteorologists publish deterministic low-temperature predictions based on atmospheric models, this market aggregates trader expectations across multiple outcome ranges. The two approaches can diverge when traders factor in longer-term climate patterns, historical volatility for early July in San Antonio, or uncertainty that standard forecasts may underweight. Comparing market-implied probabilities to National Weather Service guidance or private meteorological services can reveal where traders see additional risk or opportunity.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature outcome ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome has its own price, typically expressed as a percentage probability between 0 and 100. Traders submit limit or market orders, and the platform matches buyers and sellers in real time. The mid-market price—halfway between the best bid and ask—represents the current consensus estimate. As new information emerges or trading interest shifts, prices adjust dynamically to reflect updated market sentiment about the lowest temperature on that date.
This market resolves around Jul 7, 2026, once the event has occurred and the outcome is verifiable from credible public sources. The lowest temperature recorded in San Antonio on July 6, 2026, will be confirmed and matched against the outcome ranges offered in the market. Traders holding shares in the correct range receive their payout, while incorrect positions expire worthless. Resolution typically occurs within hours of the market close, pending final data verification. Participants should monitor official weather reporting as the date approaches to understand how their positions may settle.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts can all drive significant price movement in this market. As summer 2026 approaches, traders will react to El Niño or La Niña conditions, historical heat records, and any unusual atmospheric circulation patterns affecting South Texas. Closer to July 6, short-range model consensus and real-time atmospheric data will become the primary drivers. Extreme heat waves or unexpected cool fronts in the weeks leading up to the event could trigger sharp repricing. Additionally, any unusual local factors—such as urban heat island effects or regional drought conditions—may influence trader positioning as the resolution date nears.
