This market tracks the lowest temperature recorded in Houston on June 27, 2026. The outcome is determined by the minimum temperature reported by the National Weather Service's daily climatological report for that specific date.
Resolution is based on the minimum temperature recorded at Houston on June 27, 2026, as reported in the National Weather Service's Climatological Report (Daily) for the Houston-Hobby, TX location. The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature readings are categorized into six ranges: 72°F or below, 73-74°F, 75-76°F, 77-78°F, 79-80°F, and 81°F or above, with each range corresponding 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 authoritative source for resolution, superseding other weather data sources.
Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader behavior, risk appetite, and information beyond standard meteorological models. While meteorologists rely on atmospheric data and historical patterns, this market aggregates the financial commitments of many participants betting on specific temperature outcomes. Comparing the two reveals whether traders are pricing in tail risks or consensus scenarios that official forecasts may weight differently, offering a complementary lens on June 27 conditions.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for 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 price of each outcome reflects supply and demand; as more traders believe a particular temperature band is likely, its share price rises. Settlement values are tied to verified temperature data, ensuring that market prices remain anchored to real-world conditions throughout the trading period.
This market resolves around Jun 28, 2026, once the lowest temperature recorded in Houston on June 27, 2026 is confirmed and verifiable from credible public sources. The outcome is determined by the actual low temperature observed that day, measured by recognized meteorological stations. Once the event occurs and data is finalized, the market settles based on which temperature range the verified reading falls into.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from the National Weather Service can all drive significant price swings in this market. Tropical activity, jet stream positioning, and broader atmospheric oscillations months ahead of June 2026 will influence trader expectations. Additionally, historical temperature records for that date and any emerging climate trends may prompt reassessment of probabilities, causing traders to reposition their bets as new meteorological data emerges.
