This market will resolve to the temperature range that contains the highest 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 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 often diverge from traditional meteorological forecasts because they incorporate real-time trader positioning and risk appetite alongside expert models. While weather analysts publish deterministic or probabilistic forecasts based on atmospheric data, this market aggregates the collective judgment of traders betting real capital on specific temperature thresholds. The two sources can align closely or drift meaningfully depending on recent data releases, model consensus shifts, or trader conviction. Comparing the implied odds here to published forecasts from Hong Kong's Observatory or regional meteorologists can reveal where the market is pricing in tail risks or consensus blind spots.
This market resolves around Jul 11, 2026, once the highest temperature recorded in Hong Kong on July 11 is verifiable from credible public sources. The outcome is determined by comparing the final reported high temperature against the contract thresholds traders have wagered on. Resolution typically occurs within hours or a day after the event concludes, allowing the platform to confirm the data and settle all positions. Traders holding contracts aligned with the verified temperature outcome receive their winnings, while mismatched positions expire worthless.
Major weather model updates, tropical storm or typhoon alerts, and seasonal heat advisories can all trigger sharp repricing in this market. Real-time atmospheric pressure changes, upper-air pattern shifts, or unexpected monsoon activity could push implied probabilities higher or lower. Additionally, historical temperature records for Hong Kong in early July and recent heat waves in the region often influence trader positioning. As Jul 11, 2026 approaches, intraday weather radar data and official meteorological statements will likely drive final volatility, with traders adjusting positions hours before the event closes.
