Highest temperature in Beijing on July 12?

Platform comparison

Market context

Beijing’s highest temperature on 12 July 2026 will be recorded at the Beijing Capital International Airport Station, with settlement based on Wunderground’s daily maximum in degrees Celsius. The market resolves to the temperature range containing that peak, settling in USDC on btc-prediction.bet with on-chain mechanics tied to BTC and ETH macro flows.

Historical July data shows Beijing routinely hits 35–40°C, with 2023 reaching 40°C and 2024 marking China’s hottest July month in recent history [1][9]. The 17 July average high is 31°C (88°F), rarely dipping below 26°C or exceeding 35°C [2]. A 0% YES probability implies the crowd expects the peak to fall below the lowest range offered, which contradicts typical mid-July heat patterns where temperatures exceed 35°C in most years [1][5].

Traders should monitor the North China Plain heat dome intensity, daily Wunderground updates for ZBAA, and any official heatwave announcements from China Daily [7][10]. Funding rates on BTC/ETH perps and whale flows into USDC-stable contracts may shift as macro volatility interacts with weather-driven speculation. A sudden spike in funding rates or large USDC inflows could signal institutional positioning ahead of the 12:00 UTC settlement window.

Methodology

This page reads Highest temperature in Beijing on July 12? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

How does UMA secure the resolution?
