This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 1 Jul '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.

Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader sentiment and financial incentives. While weather analysts rely on atmospheric models and historical data, this market aggregates the beliefs of participants who have money at stake. Traders may react faster to emerging weather patterns or adjust for local factors that models lag on. Comparing the current odds to official forecasts from Hong Kong's meteorological authority can reveal where the market is pricing in additional uncertainty or confidence. Both sources offer value: analysts provide scientific rigor, while markets reflect dynamic, incentivized judgment.
This market resolves around Jul 1, 2026, once July 1 has passed and the lowest temperature recorded in Hong Kong is verifiable from credible public sources. The outcome is determined by comparing the actual minimum temperature on that date against the threshold specified in the contract. Resolution typically occurs within hours or a day after the event, once official meteorological data is published and confirmed. Traders who correctly predicted the temperature range receive their payout, while incorrect predictions result in a loss. The market's integrity depends on transparent, timely access to verified temperature readings.
Several factors could shift odds before resolution. Updated weather forecasts from meteorological agencies, especially those showing shifts in monsoon patterns or tropical systems, often trigger repricing. Real-time atmospheric data—pressure systems, humidity, wind patterns—can prompt traders to adjust positions as July 1 approaches. Major weather events or anomalies in the weeks prior may also influence expectations. Social media discussion or news coverage of Hong Kong's climate conditions can sway sentiment. Finally, as the event date nears, traders may lock in profits or cut losses, creating volume spikes that move prices independent of new weather information.
