Highest temperature in Hong Kong on July 14?

Platform comparison

Market context

On 14 July 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market settles on that single data point once the Observatory publishes its daily extract, with resolution bands covering the full plausible range from below 30°C to above 37°C.

Hong Kong's July temperatures are remarkably consistent year-on-year, with historical daily maxima clustering between 32°C and 35°C during the mid-summer period. The Observatory's 30-year climate normal for mid-July sits near 32.6°C, though extremes have reached 36.3°C (July 1975) and dipped to 29.5°C (July 1992). The 0% crowd probability across all temperature bands suggests either a technical issue with market initialisation or genuine uncertainty about which specific range will resolve. Comparable weather markets on other platforms show similar flatness, indicating traders are withholding positions until nearer the settlement date when seasonal forecasts sharpen.

The key dependency is the monsoon pattern across the South China Sea in early-to-mid July 2026. The Hong Kong Observatory typically issues extended forecasts 10–14 days ahead; traders should monitor their monthly outlooks from June onwards for signals on whether the Southwest Monsoon will bring typical convective activity (suppressing peaks) or whether a ridge of high pressure might drive temperatures toward the 35–37°C bands. Tropical cyclone activity in the region could also materially shift outcomes, though July sits outside peak typhoon season.

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 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 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.
