This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 30 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 decentralized trader consensus and often incorporate meteorological forecasts, historical climate data, and real-time weather updates. Professional meteorologists and climate analysts typically rely on numerical weather prediction models and satellite imagery to estimate temperature ranges. This market's pricing may align with or diverge from traditional forecasts depending on how traders weight recent data, seasonal anomalies, and model uncertainty. Comparing the implied probabilities here to published forecasts from Hong Kong's Observatory or international weather services can reveal where the market sees upside or downside risk relative to expert opinion.
This market resolves around Jun 30, 2026, once the highest temperature recorded in Hong Kong on that date is confirmed and verifiable from credible public sources. The outcome is determined by the official meteorological reading for June 30, typically reported by Hong Kong's Observatory or equivalent authoritative weather service. Resolution occurs after the event concludes and the final data is published, at which point the winning outcome shares are settled and payouts are distributed to holders. Traders should monitor official weather announcements and forecasts as the date approaches to refine their positions.
This market is sensitive to updated seasonal forecasts, tropical weather systems, and atmospheric patterns affecting Hong Kong in late June. Major signals include tropical cyclone warnings, monsoon intensity shifts, and anomalous heat events across East Asia. Real-time weather model updates from meteorological agencies typically drive short-term price movements as traders recalibrate expectations. Historical temperature records for late June and climate indices such as sea surface temperature anomalies can also influence positioning. As June 30 approaches, daily weather reports and final forecast updates will likely trigger the most volatile trading activity.
