Highest temperature in Hong Kong on August 2?

Platform comparison

Market context

Hong Kong’s 2 August maximum temperature will be decided by the Hong Kong Observatory’s final daily extract, and the market’s current **0% YES** implies traders see almost no chance of a specific outcome clearing at the top end of the listed range. The current crowd favourite is **27°C at 34%**, with **28°C at 32%**, so consensus is clustered around a fairly ordinary summer high rather than an extreme heat print.[2][3][14]

That pricing sits below the long-run August norm: the Observatory’s 1991–2020 daily normal for 2 August shows a **mean maximum of 31.5°C** and a mean of **28.9°C**, which suggests the market is not treating this as a simple “above average” day but as a question of where the exact peak lands once cloud, showers and sea-breeze effects are reflected in the official reading.[6] August in Hong Kong is typically hot and humid, with published climate guides commonly putting average highs around the low 30s, so a sub-30°C result would be a contrarian outcome relative to seasonal expectations.[4][8][16]

For traders, the key catalysts are the Observatory’s actual daily readings and the timing of any weather disruption through the day, rather than headlines alone, because the payout depends on the final published “Absolute Daily Max (deg. C)” in the daily extract.[14] In practice, value tends to sit with whichever bracket still looks reachable against the live forecast and recent conditions: the favourite is the consensus 27–28°C band, while the contrarian angle is that Hong Kong’s August heat profile can still produce a higher close if sunshine breaks through late or if rainfall undercuts the earlier consensus.[1][3][6]

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 Who Will Win 2026, which mirrors the Polymarket order book directly.

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 Who Will Win 2026 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.
