This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 11 Jun '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 on Polymarket reflect real-money consensus from traders pricing in meteorological data, seasonal patterns, and climate models. Analyst forecasts from weather services and climate institutes typically focus on point estimates or ranges for June temperatures in Hong Kong. Market odds often incorporate broader uncertainty and tail-risk scenarios that traditional forecasts may underweight. Comparing the two reveals whether traders are pricing in more extreme outcomes or showing greater confidence than official predictions, offering insight into market-specific risk assessment versus institutional expert opinion.
The market resolves on Jun 11, 2026, after the close of June 11 in Hong Kong. Resolution is determined by the official lowest temperature recorded on that date according to designated meteorological data sources. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. The specific measurement station and data provider used for settlement are defined in the market's terms at launch, ensuring an objective, verifiable outcome independent of trader opinion or dispute.
Key drivers include updated weather models and seasonal forecasts from meteorological agencies, tropical storm or typhoon activity in the Western Pacific that could affect Hong Kong's June climate, shifts in ocean temperatures and monsoon patterns, and real-time atmospheric data as June 11 approaches. Major climate anomalies or unexpected weather systems could trigger sharp repricing. As the event date nears, historical temperature records and final 48-hour forecasts typically exert the strongest influence on odds. Traders monitor these signals continuously to adjust positions and capture alpha before resolution.
