This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 11 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 broader uncertainty. While weather analysts rely on atmospheric models and historical data to project July temperatures in Hong Kong, this market prices in additional factors such as climate variability and trader conviction. Comparing the current odds to official forecasts from meteorological agencies can reveal whether the crowd is more bullish or bearish on cooler conditions than experts expect, though both sources aim to estimate the same underlying event.
This market resolves around Jul 11, 2026, once July 11 has passed and the actual lowest temperature in Hong Kong can be verified. The outcome is confirmed against credible public sources reporting the day's minimum temperature. Traders who correctly predicted whether the temperature would fall within their chosen range receive payouts proportional to their stake, while incorrect positions expire worthless. Resolution typically occurs within hours of the market close date once official data is published.
Several factors could shift odds before July 11 arrives. Updated seasonal forecasts, tropical storm warnings, or anomalous heat patterns reported by meteorological agencies may prompt traders to reprrice their positions. El Niño or La Niña developments affecting regional climate could influence long-term temperature expectations. Additionally, historical temperature records for early July in Hong Kong and real-time atmospheric pressure systems tracked in the days leading up to the event may trigger significant trading activity. Major weather model updates typically drive the largest price swings.
