Kalshi
This event tracks the occurrence of consecutive high-temperature days in Las Vegas during a specific week. It examines whether the daily average temperature exceeds a set threshold for multiple days in a row, reflecting potential heatwave conditions. The outcome depends on recorded weather data for the defined period.
The event evaluates whether Las Vegas experiences a specified number of consecutive days with daily average temperatures strictly above 90°F during the week of August 18–24, 2026. Data is sourced from The Weather Company for KLAS airport, with daily averages calculated as the mean of hourly temperatures from midnight to midnight local time, rounded to the nearest whole degree. Only days within the specified week contribute to streaks, and a day with exactly 90°F or fewer than 18 hourly reports breaks any streak. Markets resolve to Yes if the recorded data shows at least the required number of consecutive qualifying days by the expiration time; subsequent data revisions are ignored.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, this market is priced through a continuous order book where buyers and sellers post bids and asks for contracts representing the event’s binary outcome. The current top trading chance reflects the equilibrium price set by market participants, influenced by recent trading volume, order flow, and any emerging weather patterns affecting trader sentiment.
This market resolves around Aug 25, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, official meteorological data for the week of August 18, 2026, will be examined to determine whether the temperature criteria are met, and the market will close based on that verified result.
Between now and resolution, this market could shift based on medium- to long-range weather outlooks from major forecasting agencies, sudden shifts in atmospheric patterns like El Niño developments, or extreme early-season heat events that alter trader expectations. Any significant update from recognized climate models or government weather services is likely to generate trading volume and price swings.
