Description

This market tracks the highest temperature recorded in Washington DC on July 6, 2026. The outcome is determined by the maximum temperature reading from the National Weather Service's official daily climatological report for Washington-National Airport.

Kalshi

Resolution is based on the maximum temperature recorded at Washington DC on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Washington-National. The official data source is accessed through the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six bands: 83°F or below, 84-85°F, 86-87°F, 88-89°F, 90-91°F, and 92°F or above, with each band 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.

Frequently asked questions

On Kalshi, the DC heat record market dashboard tracks real-time odds and trading activity for the highest temperature expected in Washington DC on July 6, 2026. The interface displays current market prices, historical price movements, and trading volume to help you monitor how traders are pricing this weather outcome. This market reflects collective expectations about whether the day's peak temperature will fall within specific ranges, updated continuously as new information and trading activity flow in.

Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader sentiment and broader uncertainty. While meteorologists issue deterministic forecasts based on atmospheric models, this market aggregates the beliefs of many participants betting real capital on the outcome. Traders may price in tail risks, historical variability, or climate patterns that standard forecasts downweight. Comparing the implied probabilities here to published seasonal temperature expectations can reveal where the market sees asymmetric risk or consensus blind spots.

On Kalshi, this market is priced through an order-book mechanism where traders buy and sell contracts representing different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract's price reflects the probability traders assign to that outcome occurring. As demand shifts—driven by updated forecasts, seasonal patterns, or new climate data—the bid-ask spread widens or tightens, and prices move accordingly. Your position's value fluctuates with the collective reassessment of July 6 conditions in the nation's capital.

This market resolves around Jul 7, 2026, once the actual high temperature for July 6, 2026 in Washington DC is verifiable from credible public sources. The outcome is determined by the official recorded peak temperature on that date, confirmed through established meteorological reporting. Your position settles based on which temperature range the final reading falls into, with all contracts paying out according to the predetermined outcome brackets.

Several factors could shift odds in this market: updated seasonal climate forecasts, El Niño or La Niña patterns, historical heat-wave data, and real-time weather model runs as July 2026 approaches. Major atmospheric events—such as shifts in the jet stream or tropical activity—can reshape expectations weeks in advance. Additionally, any revision to how Washington DC records or reports temperature could influence trader positioning. Traders monitor long-range outlooks and climate indices closely, repricing the market as new evidence emerges.
