Market context
The contract is trading as a near-dead outcome on Polymarket, with the crowd-implied **1% YES** price implying an extremely low chance that the selected temperature range will be hit when the Hong Kong Observatory publishes the day’s final maximum. On Polymarket, that pricing sits in USDC on Polygon and resolves through conditional tokens, so the trade is really a claim on where the Observatory’s final “Absolute Daily Max” lands, not on whether Hong Kong merely feels hot.
For context, July in Hong Kong is typically very hot, with average daily highs around **32°C** and only limited day-to-day variation in the mean pattern; comparable climate data shows highs usually sit near **29°C to 34°C**, with 25 July itself often clustering near the seasonal peak of the month.[2][3] That makes a low single-digit price easier to understand if the market is concentrated on a narrow band at the top end of the distribution rather than on “hot weather” in general.
The practical catalysts are procedural rather than dramatic: traders should watch the Hong Kong Observatory’s daily extract publication, because this market cannot settle until the finalised data for 25 July 2026 is posted on the official climatology page.[1] With the settlement window closing at 12:00 UTC, any late-day heat spike in Hong Kong local time only matters once it is captured in that archived extract, and the final print is what determines which conditional token pays out.
Methodology
This page reviews Pronóstico: Highest temperature in Hong Kong on July 25? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Polymarket Qué Es, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
