The market resolves at Jun 8, 2026, after the highest temperature in Cape Town on June 8 has been recorded and verified. Resolution depends on official temperature data from a designated weather station or meteorological authority serving Cape Town. The outcome is determined by comparing the actual recorded high temperature against the predefined outcome brackets or thresholds established at market creation. Once the official data is confirmed, the market settles and winning positions are paid out according to their final odds.

Several factors can shift odds for Cape Town's June 8 high temperature. Updated weather forecasts from meteorological agencies, particularly those issued within 7–10 days of the event, carry significant weight as models become more precise. Unusual atmospheric patterns, such as cold fronts, heat waves, or ocean current anomalies, can trigger rapid repricing. Historical temperature records and seasonal climate trends also influence trader expectations. Real-time weather alerts, changes in solar activity forecasts, or unexpected shifts in regional pressure systems may prompt traders to adjust positions, causing odds to move before the resolution date.
