This event tracks whether Oklahoma City will experience consecutive days of high temperatures during a specific week. It focuses on the number of days in a row where the average temperature exceeds a set threshold, providing insight into potential heat patterns.
The event evaluates whether Oklahoma City records a specified number of consecutive days with average temperatures strictly above 90°F during the week of September 7–13, 2026. Each market corresponds to a different minimum streak length (2, 3, 4, 5, or 6+ days). A day’s average temperature is calculated as the mean of hourly readings from 12:00 AM to 11:59 PM local time, rounded to the nearest whole degree, using data from The Weather Company. Only days within the specified week count toward a streak. If a day’s average is exactly 90°F, or if fewer than 18 hourly values are reported, the streak is broken. The market resolves based on data published at the expiration time, with later revisions disregarded.
Currently, the collective prediction from this market offers a unique perspective compared to traditional analyst forecasts. While weather analysts provide predictions based on models and historical data, this market reflects the wisdom of the crowd, incorporating a broader range of information and potential unforeseen factors. It’s important to note that prediction market probabilities represent what traders believe will happen, which may differ from expert opinions or long-range forecasts for Oklahoma City’s September temperatures. Examining these differences can reveal valuable insights into market sentiment.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing potential outcomes. The price of a contract reflects the implied probability of that outcome occurring. As more traders participate, the prices adjust to reflect the collective assessment of the likelihood of consecutive 90°F+ days in Oklahoma City. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Price movements are driven by new information, changing weather patterns, and overall market sentiment regarding the potential for extreme heat in the region.
This market resolves around Sep 15, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will be based on the average daily temperature recorded in Oklahoma City during the week of September 7, 2026. If the average temperature exceeds 90°F on a consecutive basis for the duration of that week, the market will settle in favor of ‘yes’. Otherwise, it will settle as ‘no’, reflecting whether the heat wave criteria were met.
Several factors could significantly influence trading activity in this market. Long-range weather forecasts released closer to September 2026 will be key drivers, as will any emerging patterns suggesting a potential for a sustained heat wave. Unexpected shifts in climate models or reports of unusually warm temperatures during the preceding months could also impact trader behavior. Finally, broader economic conditions or news events related to energy demand and climate change awareness might indirectly affect sentiment and volume in this market.
