Market context

The Hong Kong Observatory will record the highest temperature in Hong Kong on 27 May 2026, with settlement determined by the official "Absolute Daily Max" figure published in the Observatory's Daily Extract once data finalisation is complete. The market currently shows 0% probability across all temperature ranges, suggesting traders are awaiting historical baseline data and seasonal patterns before committing positions.

Hong Kong's May temperatures typically range between 28°C and 33°C, with occasional peaks above 34°C during heat waves. Historical records from the Observatory show that late May sits within the pre-monsoon transition period, when subtropical high-pressure systems can drive temperatures sharply upward. The current 0% probability across all ranges reflects the absence of firm meteorological forecasts this far in advance rather than consensus that no temperature will be recorded—settlement requires only that the Observatory publishes a valid reading by the deadline.

Traders should monitor the Observatory's seasonal forecasts and broader climate pattern announcements in the months preceding May 2026. The El Niño Southern Oscillation (ENSO) phase and Indian Ocean Dipole conditions, typically forecast by the World Meteorological Organisation in early 2026, will shape regional temperature expectations. Additionally, any revision to Hong Kong's historical temperature records or methodology by the Observatory could affect how traders calibrate their probability estimates against comparable May dates from prior years.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Highest temperature in Hong Kong on May 27? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

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.
