This market tracks the lowest temperature recorded in Washington DC on June 23, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with temperature ranges divided into distinct bands to capture the full spectrum of possible overnight lows.
Resolution is based on the minimum temperature recorded at Washington-National on June 23, 2026, as reported in the National Weather Service's Climatological Report (Daily), accessible via the Washington DC NWS climate portal. The minimum temperature is divided into six ranges: 63°F or below, 64–65°F, 66–67°F, 68–69°F, 70–71°F, and 72°F or above. Each range corresponds to a distinct outcome. The official NWS Climatological Report (Daily) serves as the authoritative data source; preliminary NWS reporting and other weather services are for reference only. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances that could affect interpretation of borderline temperatures.
Prediction market odds often diverge from traditional meteorologist forecasts because they incorporate real-time trader conviction and broader information flows. While weather analysts publish deterministic low-temperature predictions based on numerical models, this market aggregates the collective judgment of participants betting on specific ranges. Prediction markets tend to update faster than seasonal outlooks when new data arrives, and they can reflect tail-risk scenarios that analysts downplay. Comparing this market's leading outcome to official National Weather Service guidance for that date can reveal where traders see asymmetric opportunities or disagreement with consensus models.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to specific temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome bracket has its own bid-ask spread, and the midpoint reflects the implied probability that the low will fall within that range. As new information emerges—updated forecasts, seasonal patterns, or real-time weather developments—traders adjust their positions, moving prices up or down. The platform's matching engine ensures transparent price discovery, with all trades visible in the order history.
This market resolves around Jun 24, 2026, once June 23, 2026 has passed and the actual low temperature in Washington DC is recorded. The outcome is confirmed against credible public sources, typically the National Weather Service or equivalent official meteorological data. Traders holding shares in the outcome bracket that matches the verified low receive their payout, while other positions expire worthless. Resolution is automatic once the temperature reading is finalized and published.
Major weather pattern shifts, updated seasonal forecasts, and atmospheric oscillations like the North Atlantic Oscillation can significantly move this market. Real-time model runs released by the National Weather Service or European weather centers often trigger repricing as traders adjust their temperature expectations. Unusual jet-stream configurations or blocking patterns weeks in advance can signal whether June 23 will be warmer or cooler than climatological norms. Additionally, any significant heat waves or cold snaps affecting the Eastern Seaboard in the weeks prior may shift trader positioning on what the DC low will ultimately be.
