Description

This event tracks the highest temperature recorded in Houston on June 25, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for Houston-Hobby, TX, which provides the authoritative temperature measurement for that date.

Kalshi

Resolution is based on the maximum temperature recorded at Houston-Hobby, TX on June 25, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 90°F or below, 91-92°F, 93-94°F, 95-96°F, 97-98°F, and 99°F or above. Each range corresponds to a specific market outcome. The official data source is accessed through the NWS website at the Houston/Galveston office, selecting the Observed Weather tab and Houston-Hobby location with Daily Climate Report. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be used for resolution rather than preliminary readings or third-party weather services.

Frequently asked questions

On Kalshi, the Houston temperature market dashboard tracks real-time odds and historical price movement for predictions on the highest temperature in Houston on June 25, 2026. The interface displays current market pricing, 24-hour trading volume, and a price history chart that reflects how trader sentiment has shifted as new weather data and seasonal forecasts emerge. This live feed lets you monitor how the market is pricing different temperature outcomes and compare your own forecast against the collective prediction of active traders.

Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader positioning, historical volatility, and broader economic or seasonal signals beyond raw weather models. While meteorologists publish deterministic temperature ranges based on atmospheric data, this market aggregates the beliefs of many participants with financial incentives to be accurate. Over time, prediction markets have proven competitive with or superior to expert consensus on specific outcomes, though they reflect market sentiment rather than a single authoritative forecast.

On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome has its own price, typically ranging from $0 to $1, and the sum of all outcome prices reflects the implied probability distribution. As traders place bids and offers, prices adjust in real time, allowing you to enter or exit positions at transparent, market-determined rates.

This market resolves around Jun 26, 2026, once the highest temperature recorded in Houston on June 25, 2026 is verifiable from credible public sources. The outcome is determined by the official temperature reading for that date, confirmed through established meteorological records. Traders holding shares in the correct outcome receive their payout once the event is settled and verified.

Major weather pattern shifts, updated seasonal climate forecasts, and historical temperature anomalies for Houston in late June can all influence trader positioning. El Niño or La Niña conditions, broader heat waves affecting the Gulf Coast region, and long-range model updates from the National Weather Service are key catalysts. Additionally, as June 2026 approaches, real-time atmospheric data and short-term forecasts will become increasingly relevant, likely driving sharper price movements in the final weeks before resolution.
