The minimum temperature in Oklahoma City on May 31, 2026, will be recorded according to the National Weather Service's daily climatological data. This event covers the full range of possible temperature outcomes.
Prediction market odds on Kalshi reflect real-money trader consensus and typically incorporate meteorological data, historical May temperature patterns for Oklahoma City, and seasonal climate models. Analyst forecasts from the National Weather Service and climate research institutions provide independent baseline estimates. Markets often price in broader uncertainty and tail-risk scenarios that traditional forecasts may underweight. Comparing Kalshi odds to published analyst ranges helps identify whether traders are more bullish or bearish on extreme temperatures relative to expert consensus. Divergence between venues can signal emerging information or shifting confidence in seasonal outlooks.
On Kalshi, the lowest temperature in Oklahoma City on May 31, 2026 is priced as binary or range-based contracts reflecting specific temperature thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders buy or sell shares corresponding to whether the official recorded low will fall above or below predetermined strike levels. Prices move based on order flow, weather model updates, and real-time market demand. Each contract settles to 1 or 0 depending on the actual temperature reading from the National Weather Service or designated weather station. The bid-ask spread and liquidity on Kalshi determine how efficiently traders can enter or exit positions ahead of the May 31 observation window.
The market resolves on Jun 1, 2026, after the lowest temperature for May 31, 2026 in Oklahoma City is officially recorded and reported. Resolution timing allows for official weather data to be published and verified by the relevant meteorological authority. The outcome is determined by the actual minimum temperature observed on that calendar date at the designated weather station serving Oklahoma City. Once the official reading is confirmed, contracts settle according to whether the temperature fell within or outside the specified range or threshold defined at market creation.
Major signals include updated seasonal climate forecasts, atmospheric pattern shifts favoring warmer or cooler air masses over the central United States, and historical analogs from prior May 31 observations in Oklahoma City. Real-time weather model runs in late May will become increasingly influential as the date approaches. Broader climate oscillations such as La Niña or El Niño phases, jet stream positioning, and high-pressure or low-pressure systems developing over the region can all shift market odds. Trader positioning and new meteorological data releases will drive price adjustments throughout the lead-up period.
