Market context
Hong Kong's weather on 9 June 2026 will determine the highest temperature recorded by the Hong Kong Observatory that day, measured to one decimal place in Celsius. The settlement window closes at midday on the specified date, with resolution dependent on official data publication from the Observatory's Daily Extract records.
Historical temperature records for Hong Kong in early June show considerable variation. The territory's climate transitions into the pre-monsoon season, with average daily maxima around 31–32°C, though extremes have reached into the mid-to-high 30s during heat waves. The 0% crowd probability suggests traders are either awaiting clearer seasonal forecasts or treating this as a calibration exercise given the eighteen-month lead time. Comparable June dates from the Observatory's archives provide the primary benchmark for assessing plausible ranges, though long-range weather prediction carries substantial uncertainty at this distance.
Traders should monitor the Hong Kong Observatory's seasonal outlooks and any El Niño or La Niña developments that typically influence regional temperatures. Tropical cyclone activity, whilst more common later in the season, can suppress temperatures if systems approach in early June. The Observatory publishes monthly climate summaries and three-month forecasts that may shift probability distributions as June 2026 approaches. Current atmospheric patterns and sea-surface temperature anomalies tracked by regional meteorological agencies will provide the most actionable signals for adjusting positions closer to the resolution date.
Methodology
This page tracks Highest temperature in Hong Kong on June 9? across four political prediction venues. Live odds come from the Polymarket order book (the deepest political prediction-market book). Kalshi is the CFTC-regulated US alternative, Betfair the established UK sports-exchange with politics markets, Manifold the open play-money variant. Election Predictions UK routes every trade through to Polymarket — at 0% fees.
Resolution & payout
Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.
Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.
