The market resolves on Jun 1, 2026, after June 1 has concluded and the actual highest temperature in Guangzhou is recorded. Resolution depends on official meteorological data from a designated source, typically China's national weather service or a recognized regional authority. The recorded peak temperature for that calendar day determines which outcome bracket or specific value wins.

Several factors can shift odds for Guangzhou's peak temperature on June 1. Seasonal monsoon patterns and atmospheric pressure systems developing over East Asia will influence trader expectations. Updated numerical weather models from meteorological agencies, released regularly in the weeks before June 1, often trigger significant repricing. Urban heat island effects and local pollution levels can affect actual temperatures. Major weather events like tropical cyclones or unusual jet-stream configurations may prompt rapid market moves. As June 1 approaches, real-time satellite imagery and short-range forecasts become more reliable, typically narrowing the range of plausible outcomes and concentrating trading volume around the most likely temperature bands.
