Highest temperature in Hong Kong on July 14?

Platform comparison

Market context

Hong Kong's daily maximum temperature on 14 July 2026 will be recorded by the Hong Kong Observatory and published in their Daily Extract dataset. The settlement hinges on the "Absolute Daily Max (deg. C)" figure, reported to one decimal place, which determines which temperature band resolves YES. The 0% crowd probability suggests either extreme confidence in a specific range or insufficient liquidity across all outcome bands.

July sits within Hong Kong's peak summer season, when daily maxima typically range between 32–35°C, though heat waves can push readings above 36°C. Historical data from the Observatory shows that extreme heat events (38°C+) occur roughly once per decade in mid-July, whilst readings below 31°C are rare. Examining the Observatory's climate archive for comparable dates reveals the distribution of outcomes: most years cluster in the 33–34°C band, with occasional outliers. A trader building a programmatic model should weight recent decade trends more heavily than longer-term averages, as urban heat island effects have shifted Hong Kong's baseline upwards.

The key dependency is publication timing. The Observatory typically releases Daily Extract data within 48 hours of the observation date, though official finalisation can extend to several days. Traders automating conditional orders should monitor the Observatory's data portal directly rather than relying on secondary sources, as transcription errors occasionally occur in aggregated weather databases. Tropical cyclone activity in early July could materially alter atmospheric conditions; the Hong Kong Observatory's seasonal forecast and any typhoon warnings issued in the week prior will signal whether outlier temperatures become probable.

Methodology

We track Highest temperature in Hong Kong on July 14? across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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 Polymarket Review 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.
