This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 25 Jun '26. The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (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.

Prediction market odds reflect aggregated trader expectations and often diverge from traditional meteorological forecasts. While weather analysts rely on numerical models and historical climate data, this market prices in real-time information and trader conviction. The current odds suggest strong confidence in a particular outcome, though official forecasts from Hong Kong's Observatory may differ based on their modeling approach. Comparing the two reveals whether traders are more or less bullish than institutional weather services, offering insight into market-specific risk assessment.
This market resolves around Jun 25, 2026, once the highest temperature recorded in Hong Kong on June 25 is verifiable from credible public sources. The outcome is determined by comparing actual meteorological readings against the prediction thresholds embedded in the market's contract. Traders holding positions aligned with the final temperature outcome receive payouts proportional to their stake, while opposing positions expire worthless. Resolution typically occurs within hours of the event closing, pending confirmation from official weather data.
Several factors could shift odds before Jun 25, 2026. Updated seasonal forecasts, tropical weather systems, or atmospheric anomalies reported by meteorologists may trigger repricing. Major climate or weather news—such as unusual heat patterns or monsoon activity—could influence trader positioning. Real-time weather model updates in the days leading up to June 25 often prompt significant trading volume. Additionally, historical temperature records for that date and recent Hong Kong climate trends serve as reference points traders monitor to refine their probability estimates.
