This event tracks the peak temperature in Oklahoma City on June 30, 2026, using official National Weather Service daily climate data. The outcome will be determined by the maximum temperature recorded at Oklahoma City Will Rogers Airport on that date.
Resolution is based on the maximum temperature recorded at Oklahoma City on June 30, 2026, according to the National Weather Service's Climatological Report (Daily) for CLIOKC. The official data source is accessed via the NWS website by navigating to the Observed Weather tab and selecting Oklahoma City Will Rogers Airport with Daily Climate Report. Temperature ranges are categorized as follows: 93°F or below, 94-95°F, 96-97°F, 98-99°F, 100-101°F, and 102°F or above. Each range corresponds 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, superseding other weather services.
Prediction market odds reflect aggregated trader expectations and often incorporate real-time information faster than traditional weather forecasts. While meteorologists typically issue seasonal outlooks and extended forecasts months in advance, this market allows traders to price in updated climate models, historical temperature records, and emerging atmospheric patterns. The gap between market odds and analyst consensus can signal where traders see underappreciated risk or opportunity relative to official forecasts.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares representing different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Prices move based on supply and demand, with higher prices indicating greater perceived likelihood of a particular temperature range. Traders can place limit or market orders to express their views, and the spread between bid and ask prices reflects market confidence and liquidity around the event.
This market resolves around Jul 1, 2026, once the highest temperature recorded in Oklahoma City on June 30, 2026 is verified and finalized. The outcome is confirmed using credible public reporting from established weather monitoring sources. Traders holding positions aligned with the verified temperature outcome receive their payouts, while those on the opposite side of the trade realize losses.
Major climate patterns such as La Niña or El Niño cycles, seasonal drought conditions, and updated long-range weather models can shift market odds significantly. Real-time atmospheric data, tropical storm activity, and heat dome forecasts in the weeks before June 30 will drive price movements. Additionally, historical temperature records for that date and broader warming trends in the region may influence trader positioning as the event approaches.
