This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
The market resolves on Jun 10, 2026, after the highest temperature in Shanghai on June 10 has been recorded. Resolution is determined by official temperature data for that day, typically sourced from Shanghai's meteorological authority. The outcome settles based on whether the recorded high meets or exceeds the specified threshold, converting trader positions to final payouts. Traders should monitor official weather stations and announcements as the event date approaches to understand how resolution will be determined.
Key signals include seasonal weather pattern updates, monsoon forecasts, and atmospheric pressure systems affecting East Asia in early June. El Niño or La Niña conditions can influence regional temperatures. Real-time weather models released in the days leading up to June 10 will sharpen expectations, as will any unusual heat waves or cold fronts in the region. Trading volume and price shifts on Polymarket often accelerate as the resolution date nears and meteorological confidence increases, reflecting traders' updated beliefs about Shanghai's peak temperature.
