This market tracks the lowest temperature recorded in Austin on July 10, 2026, using official National Weather Service data from Austin Bergstrom Airport. The outcome will be determined by the minimum temperature reading on that specific date.
Resolution is based on the minimum temperature recorded at Austin Bergstrom on July 10, 2026, as reported in the National Weather Service's Climatological Report (Daily). 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 outcome. Official data must be obtained from the NWS Climatological Report via the specified URL, selecting Austin Bergstrom 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) values. 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 often diverge from traditional weather forecasts because they incorporate real-time trader sentiment and incentivize accuracy through financial stakes. While meteorologists rely on atmospheric models and historical data, this market reflects what informed participants actually believe will occur, weighted by their conviction. Comparing the odds here to published forecasts from the National Weather Service or private weather firms can reveal where market participants expect greater or lesser confidence in a particular outcome. Both approaches have merit: markets excel at aggregating dispersed information, while institutional forecasters leverage specialized modeling.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares tied to specific temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects supply and demand; as more traders buy shares predicting a colder day, that outcome's price rises, and vice versa. Settlement occurs at a fixed price once the event resolves, so traders profit or lose based on whether their prediction matched the actual low temperature. This mechanism ensures prices stay aligned with genuine market expectations throughout the trading period.
This market resolves around Jul 11, 2026, once July 10, 2026 has passed and the lowest temperature for that day is verifiable from credible public sources. The outcome is determined by comparing actual recorded temperatures against the ranges offered in the market, with the correct range paying out in full. Traders who predicted the winning temperature band receive their winnings, while incorrect predictions expire worthless. Resolution is typically finalized within hours of the event, pending confirmation from official weather data.
Major weather pattern shifts, seasonal forecasts, and updated climate models can all influence trader expectations and move odds significantly. Tropical systems, heat domes, or cold fronts approaching Texas in early July would trigger rapid repricing as participants adjust their bets. Long-range forecasts released by meteorological agencies may also sway sentiment if they suggest unusual conditions. Additionally, historical temperature records for that date and broader climate trends could prompt traders to reassess probabilities. Real-time trading activity itself—large buy or sell orders—can accelerate price movement as the event date approaches.
