Highest temperature in Hong Kong on July 14?

Platform comparison

Market context

The Hong Kong Observatory will record the highest temperature in Hong Kong on 14 July 2026, measured to one decimal place in degrees Celsius. This single daily maximum will determine which temperature band the market resolves to, with settlement occurring after the Observatory publishes its Daily Extract for that date. The 0% crowd-implied probability suggests traders are either awaiting range options to be specified or treating this as a placeholder market pending clarification of the exact temperature brackets available for wagering.

Hong Kong's July temperatures are remarkably consistent year-on-year, with historical daily maxima typically clustering between 31°C and 34°C during mid-July. The Observatory's 30-year climate data shows July averages around 32.3°C, with extreme heat events (35°C+) occurring in roughly 5–10% of July days. Traders should reference the Observatory's published normals and recent July performance; the 2023 and 2024 summer seasons saw several days exceeding 34°C during this period, providing a baseline for assessing probability distributions across potential ranges.

The primary dependency for this market is the publication schedule of the Hong Kong Observatory's Daily Extract, which typically appears within 24–48 hours of the observation date. Tropical cyclone activity or unusual atmospheric patterns in early July 2026 could shift expectations materially; traders should monitor the Observatory's seasonal forecasts and any typhoon warnings issued in the week preceding 14 July. The settlement window closes at 12:00 UTC on the resolution date, allowing only morning-published data to inform final resolution.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Best Prediction Markets UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
