The market resolves on Jun 5, 2026, after the lowest temperature recorded in Shanghai on June 5 is officially published. Resolution depends on identifying the actual minimum temperature reached that day from authoritative weather data sources. Once the official low is confirmed, the corresponding outcome contract is settled at full value while all other temperature outcomes expire worthless. Traders should monitor official Shanghai meteorological records as the resolution date approaches to anticipate the final outcome.

Major weather pattern shifts, tropical cyclone activity, or unexpected atmospheric blocking systems could significantly alter Shanghai's June 5 low temperature. Updated seasonal forecasts from meteorological agencies, real-time atmospheric data, and historical temperature anomalies for early June will influence trader expectations. As June 5 approaches, short-range weather models become more reliable, often triggering sharp market repricing. Additionally, any unusual heat waves or cold snaps affecting East Asia in late May could shift market odds for Shanghai's minimum temperature on that specific day.
