Kalshi
This market tracks whether the lowest temperature recorded in Los Angeles on May 28, 2026, will exceed 60 degrees Fahrenheit according to the National Weather Service's Climatological Report. On Kalshi, the leading outcome—that the minimum temperature will be greater than 60°F—stands at 99.0%. Resolution will be determined by the official National Weather Service daily climatological data reported for Los Angeles on May 28, 2026, with settlement occurring the following day based on the recorded minimum temperature reading.
Prediction market odds on Kalshi reflect real-money consensus from traders pricing in available meteorological data and seasonal patterns for Los Angeles in late May. Traditional weather analysts and the National Weather Service typically issue forecasts closer to the event date, whereas prediction markets incorporate forward-looking expectations months in advance. The market odds represent a decentralized estimate of temperature likelihood, often differing from single-source forecasts because traders aggregate diverse information and adjust continuously as new weather models and climate signals emerge.
The market resolves on May 29, 2026, after the calendar date of May 28, 2026 has passed and actual temperature data is recorded. The outcome is determined by the official lowest temperature reading for Los Angeles on that date. Resolution occurs once verified meteorological data becomes available, ensuring that the winning contract corresponds to the true minimum temperature observed. Traders should monitor weather station reports and official climate records as the resolution date approaches to understand which temperature bracket will ultimately be correct.
Several factors could shift odds for the lowest temperature in Los Angeles on May 28. Updated seasonal climate forecasts and long-range weather models issued by meteorological agencies will influence trader expectations. El Niño or La Niña patterns, Pacific Ocean temperatures, and upper-atmosphere pressure systems can alter spring weather in Southern California. As May 2026 approaches, medium-range forecasts become more precise, typically causing sharper price movements. Additionally, any unusual atmospheric events or anomalies reported in the months leading up to late May could prompt traders to reassess their temperature predictions and adjust contract prices accordingly.
