This market resolves around Jun 25, 2026, once the highest temperature recorded in Mexico City for June 25 becomes verifiable from credible public sources. The outcome is determined by the actual peak temperature reading on that date, confirmed through official meteorological records. Traders holding shares in the correct temperature band receive their payout once the event occurs and the result is finalized on the platform.
Several factors could shift odds before resolution. Updated seasonal forecasts or climate anomalies—such as heat waves or unusual atmospheric patterns—often trigger sharp repricing. Major weather events in neighboring regions can signal broader conditions affecting Mexico City. Real-time meteorological data releases, changes in atmospheric pressure systems, and even historical temperature comparisons for similar dates influence trader positioning. As June 25 approaches, intraday forecasts become more precise, typically narrowing the range of plausible outcomes and concentrating trading volume around the most likely temperature bands.
