Market context
Polymarket is pricing this Hong Kong heat contract at **0% YES** in USDC on Polygon, which means the current on-chain market is saying a specific temperature band for the day’s maximum is effectively unwagered for now. The market will settle off the Hong Kong Observatory’s *Absolute Daily Max* for 27 July 2026, so holders of the conditional tokens are really trading the eventual published official figure rather than any live forecast headline.
For context, a recent comparable Hong Kong temperature market resolved at **30°C** on 19 July 2026, with the contract finishing at full value once the Observatory confirmed the daily maximum. That is a useful reminder that these markets can move sharply once the official extract lands, especially when traders are focused on the exact bracket rather than the broad weather picture. Hong Kong in July is also typically a humid, rain-prone period; one recent July outlook for the city highlighted heavy rainfall and persistently wet conditions, which can cap daytime highs even when the air feels oppressive.
The key catalysts are the Hong Kong Observatory’s daily reporting cadence, the timing of the finalised climate extract, and any late-day weather shift before the settlement window closes. Because resolution depends on the Observatory’s published data and not a private forecast, traders should watch for the updated “Daily Extract” page to appear, along with any operational delay in finalising the month’s climatology record. In practice, the contract can remain pinned at zero until the official number is visible, then reprice quickly once the exact Celsius value is confirmed.
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 Polymarket Qué Es, 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
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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 Qué Es 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.
