This market tracks the highest temperature recorded in San Antonio on June 28, 2026. The outcome will be determined by the official National Weather Service Climatological Report for San Antonio, which records daily maximum temperatures. Temperature data is sourced from the NWS Daily Climate Report rather than commercial weather services.
Resolution is based on the maximum temperature recorded at San Antonio on June 28, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS website by navigating to the Observed Weather tab and selecting San Antonio with Daily Climate Report. Outcomes are divided into six temperature bands: 91°F or below, 92-93°F, 94-95°F, 96-97°F, 98-99°F, and 100°F or above. Each band resolves to Yes if the recorded maximum falls within that range. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) is the authoritative source, not preliminary reports or third-party weather services.
Prediction market odds on this market reflect real-time consensus from active traders, often incorporating meteorological models and historical temperature data faster than traditional analyst forecasts. While weather analysts typically issue point estimates or narrow ranges based on atmospheric models, markets aggregate dispersed information through price discovery. Traders betting on higher or lower outcomes effectively crowdsource expectations about June conditions in San Antonio. Over time, prediction markets have demonstrated competitive accuracy against expert forecasts, particularly when liquidity is robust and participants have strong incentives to price outcomes correctly. Comparing current odds to recent analyst statements can reveal where market participants expect divergence from official predictions.
This market resolves around Jun 29, 2026, once the highest temperature recorded in San Antonio on June 28, 2026 is verified and confirmed. The outcome is determined by the actual daily high temperature on that date, measured against credible public sources. Traders holding shares in the correct outcome bracket receive their payout shortly after verification. Until that point, prices remain fluid as new information about seasonal patterns, climate anomalies, or long-range forecasts influences trader positioning. The resolution process is final once the temperature data is locked in, and all positions settle according to the bracket in which the actual high falls.
Several factors could shift prices in this market significantly. Long-range weather forecasts and seasonal climate outlooks released by meteorological agencies often trigger repricing as traders incorporate new data. El Niño or La Niña patterns, atmospheric pressure systems, and historical temperature anomalies for late June in San Antonio all influence expectations. Major climate events or unusual atmospheric conditions months ahead of the date can alter baseline assumptions. Additionally, as June 2026 approaches, weekly and daily forecasts become more precise, typically narrowing outcome ranges and concentrating liquidity around the most probable temperature bracket. Traders monitoring these signals adjust positions accordingly, creating price momentum that reflects evolving consensus about what the actual high will be.
