The Highest temperature in Seoul on May 30 market resolves on May 30, 2026, after the day's weather data is finalized. Resolution is determined by the actual highest temperature recorded in Seoul on May 30. The outcome that matches the official recorded temperature will be deemed correct, and traders holding shares in that outcome receive their payout. Markets typically close to new trades shortly before the resolution timestamp to allow time for data verification and settlement processing.
Several factors could shift odds for Seoul's highest temperature on May 30. Updated weather forecasts from meteorological agencies, particularly those issued 7–14 days before the event, often trigger significant repricing. Seasonal climate anomalies, such as early heat waves or unexpected cold fronts, can alter trader expectations. Historical temperature patterns for late May in Seoul provide a baseline, but deviations from normal conditions drive trading activity. Real-time atmospheric data, ocean temperatures, and pressure systems also influence market sentiment as May 30 approaches.
