This market tracks the highest temperature recorded in San Antonio on June 14, 2026, using official National Weather Service data from San Antonio, Texas. The outcome is determined by which temperature range the recorded maximum falls into, spanning from below 88°F to 96°F or above.
Resolution is based on the maximum temperature recorded at San Antonio on June 14, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Austin office website under the Observed Weather tab. Temperature ranges are: below 88°F, 88-89°F, 90-91°F, 92-93°F, 94-95°F, and 96°F or above. 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 authoritative source, superseding other weather services.
Prediction market odds aggregate the collective judgment of traders betting real money on outcomes, whereas traditional analyst forecasts rely on meteorological models and expert opinion. This market incorporates forward-looking trader behavior and incentives to be accurate, often capturing shifts in expectations faster than static forecasts. Comparing odds here to published weather forecasts from the National Weather Service or other meteorological authorities can reveal where the market expects conditions to diverge from baseline predictions. Both sources offer value: markets excel at pricing uncertainty, while institutional forecasters provide detailed physical reasoning.
On Kalshi, this market is priced through a continuous order book 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.

The bid-ask spread tightens as volume increases and resolution approaches, making prices more efficient. Kalshi's regulatory framework ensures transparent pricing and settlement aligned with verifiable real-world data.
This market resolves around Jun 15, 2026, once the highest temperature recorded in San Antonio on June 14, 2026 is verified and confirmed.

Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies will influence trader positioning in this market. El Niño or La Niña conditions, atmospheric pressure systems, and historical temperature records for mid-June in San Antonio all serve as reference points. As June 14, 2026 approaches, short-range weather models become more precise, typically causing prices to converge toward a narrower range. Breaking news about climate events or unusual atmospheric conditions could trigger rapid repricing as traders adjust their expectations.
