Highest temperature in Beijing on July 25?

Platform comparison

Market context

On 25 July 2026, the highest temperature recorded at Beijing Capital International Airport will fall into one of several defined ranges. In a prediction market, traders buy YES or NO shares corresponding to each range. A YES share pays out if that range contains the actual recorded high; a NO share pays out if it does not. The settlement source is Wunderground's historical weather database for that specific station and date, making the outcome objective and verifiable once the day concludes.

Beijing's July temperatures are among the year's most extreme, with historical highs regularly exceeding 35°C. The 30-year average maximum for late July sits around 32–33°C, though the city has recorded peaks above 40°C during heat waves. The current 0% crowd probability on any single range reflects genuine uncertainty: without knowing which temperature bracket the market offers, traders cannot yet assess whether conditions will trend toward seasonal norms, mild heat, or exceptional extremes. Historical volatility in summer weather patterns—driven by monsoon positioning and urban heat-island effects—means even experienced forecasters treat July predictions with caution.

The primary catalyst is the East Asian summer monsoon's strength and timing in early-to-mid July 2026, which influences whether cooler, moisture-laden air reaches northern China or whether high-pressure systems dominate. China's meteorological agency typically issues seasonal outlooks by June, providing the first formal guidance on expected temperature ranges. Real-time atmospheric data from late June onwards will sharpen expectations, but the inherent unpredictability of synoptic weather patterns means significant probability shifts remain possible until settlement.

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.

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.

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 Prediction Market 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.
