Description

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 30 Jun '26. The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm This market can not resolve until data for this date has been published. The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.

Frequently asked questions

The Hong Kong temperature market dashboard on Polymarket tracks real-time odds and trading activity for predictions about the lowest temperature in Hong Kong on June 30. Traders buy and sell shares based on their forecasts, with current odds reflecting the collective expectation across the platform. The dashboard displays the leading outcome, live price movements, and volume of $44,183 in total activity, plus $1,585 traded in the last 24 hours. This gives participants a transparent view of how the market is pricing different temperature scenarios as the event date approaches.

Prediction market odds often diverge from traditional analyst forecasts because they reflect real-money incentives and continuous price discovery rather than static models. While meteorologists may issue point estimates or ranges based on historical data and atmospheric models, this market aggregates the beliefs of traders who profit or lose based on accuracy. Comparing the leading outcome's implied probability to published weather forecasts can reveal where the market is more bullish or bearish than experts. Such gaps sometimes signal either market inefficiency or information that analysts have not yet incorporated into their public guidance.

This market resolves around Jun 30, 2026, once June 30 has passed and the lowest temperature recorded in Hong Kong that day is confirmed. The outcome is determined by verifying the actual temperature reading against credible public sources. Whichever outcome bracket or specific temperature prediction matches the official record will be deemed correct, and traders holding winning shares receive their payout. Until that point, prices remain fluid as participants trade on their expectations and react to weather forecasts and real-time conditions.

Several factors can shift odds significantly before the market closes. Updated weather forecasts from meteorological agencies often trigger repricing, especially as June 30 draws nearer and models become more reliable. Seasonal climate patterns, historical temperature data for that date, and any unusual atmospheric conditions reported in the weeks leading up to the event can all influence trader sentiment. Real-time weather developments—such as tropical systems, heat waves, or cold fronts—may also prompt sharp moves. Early trading volume and initial price discovery can establish momentum that either attracts or repels additional capital into this market.
