This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 16 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 often diverge from traditional weather forecasts because they incorporate real-time trader sentiment and financial incentives alongside meteorological models. While official forecasters publish point estimates and confidence intervals based on atmospheric data, this market aggregates the collective judgment of participants who have money at stake. Traders may price in tail risks, recent model updates, or historical volatility that analysts downweight. Comparing the implied probabilities here to consensus forecasts from Hong Kong's Observatory or regional weather services can reveal where market participants see asymmetric opportunities or disagree with conventional wisdom.
On Polymarket, this market is priced through an automated market maker that sets odds based on the ratio of shares bought and sold for each temperature outcome. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders purchase shares representing their belief about the lowest temperature, and the price of each outcome adjusts dynamically as volume flows in or out. Higher demand for a particular temperature range pushes its price up and probability higher; conversely, selling pressure lowers it. This continuous repricing mechanism ensures the market stays liquid and reflects the latest information available to participants.
This market resolves around Jun 16, 2026, once the event is verifiable from credible public reporting. The outcome is determined by the actual lowest temperature recorded in Hong Kong on June 16, confirmed through official meteorological data. Traders holding shares in the correct outcome bracket receive their payout, while incorrect positions expire worthless. The resolution window typically closes shortly after the day ends and the final temperature reading is published, ensuring all participants have access to the same authoritative information.
Major weather pattern shifts, tropical storm warnings, or updated seasonal forecasts could significantly move this market. Real-time model runs from meteorological centers often trigger repricing as traders adjust positions based on new atmospheric data. Unusual heat waves or cold fronts in the region weeks before June 16 may shift baseline expectations. Media coverage of extreme weather elsewhere in Asia can also influence sentiment. Additionally, historical temperature anomalies or El Niño updates might prompt traders to reassess probabilities. Close to the event date, hourly forecasts and overnight low predictions will drive the most volatile price swings.
