This market tracks whether the lowest temperature recorded in Las Vegas on May 28, 2026, will fall within the 57-58° Fahrenheit range. On Kalshi, the leading outcome—that the minimum temperature stays in that band—stands at 99.0%, while the possibility of temperatures exceeding 60° is priced at 1.0%. Resolution will be determined by the National Weather Service's Climatological Report (Daily) for that date. Watch the actual low temperature reading on May 29, 2026, when the National Weather Service publishes its official daily report for Las Vegas.
The market resolves on May 29, 2026, after the May 28, 2026 trading day concludes and the lowest temperature for Las Vegas is officially recorded. Resolution depends on the actual minimum temperature observed in Las Vegas on that date. The specific temperature threshold or range determines which contracts pay out and which expire worthless. Traders should monitor official weather data sources and market announcements as the resolution date approaches to understand how outcomes will be determined and settled.
Several factors could shift market odds for the lowest temperature in Las Vegas on May 28, 2026. Long-range weather models updated in the months leading to May will influence trader expectations as forecasts become more precise. Major climate patterns, such as high-pressure systems or unusual jet-stream positioning, could signal warmer or colder conditions. Historical temperature trends and seasonal anomalies may prompt traders to adjust positions. Additionally, any significant weather events or atmospheric disturbances in the weeks before May 28 could alter the probability of extreme cold or warmth, causing market prices to move as new information becomes available.
