This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 4 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 reflect real-money incentives for accuracy, often capturing forward-looking sentiment that differs from traditional weather forecasts. While meteorologists rely on atmospheric models and historical data to project temperatures, traders in this market incorporate broader information—including seasonal patterns, climate anomalies, and recent weather trends—into their pricing. The market's odds can diverge from analyst consensus when traders anticipate conditions forecasters may have underweighted, making side-by-side comparison useful for understanding both institutional and crowd-sourced temperature expectations.
This market resolves around Jul 4, 2026, once July 4 has passed and the highest temperature in Hong Kong can be verified. The outcome is confirmed when the recorded peak temperature is available from credible public sources, allowing the market to settle according to the temperature thresholds embedded in each outcome. Traders should monitor weather reporting and official meteorological data as the event date approaches to assess how conditions align with their positions.
Several factors could shift odds in this market: updated seasonal forecasts from meteorological agencies, unusual weather patterns or heat waves affecting the region, changes in ocean temperatures or atmospheric pressure systems, and real-time weather updates as July 4 approaches. Major climate events or anomalies in the weeks prior could also influence trader expectations. As the resolution date nears, intraday weather reports and live temperature readings will likely drive final price movements, with traders adjusting positions based on how actual conditions compare to their predictions.
