Highest temperature in Beijing on July 6?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded at Beijing Capital International Airport on 6 July 2026, measured in degrees Celsius. Polymarket prices this contract today with a 43% probability for 34°C and a 36% chance for 33°C, while the crowd-implied probability for a 0% YES outcome sits at 0%, suggesting traders expect temperatures well above freezing. This pricing reflects on-chain mechanics where USDC trades on Polygon using conditional tokens, locking liquidity into temperature-range outcomes rather than abstract weather speculation.

Historical data frames how to interpret these probabilities: July in Beijing typically sees daily highs around 88°F (31°C), rarely falling below 78°F (26°C) or exceeding 96°F (36°C), with the highest average high reaching 88°F on 17 July[3]. In 2023, Beijing hit 40°C (104°F) during the hottest month, and China recorded its most hot days in six decades, averaging 4.1 days above 35°C since 1961[4][5]. These precedents make the current 34°C frontrunner plausible, as extreme heatwaves have become more frequent in northern China.

Traders should monitor the Beijing Meteorological Bureau’s daily forecasts and Wunderground’s real-time updates for the airport station, as humidity and heatwave schedules directly influence peak temperatures[5]. Recent news from Global Times confirms China’s rising trend in extreme heat, with state media reporting 52.2°C in northwest China in July 2023, underscoring the volatility of regional weather patterns[4][8]. The settlement window ends 12:00 UTC on 6 July 2026, so timely data from Wunderground will determine the final resolution.

Methodology

This page reviews Highest temperature in Beijing on July 6? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Kalshi UK, which mirrors the Polymarket order book at 0% fees.

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 Kalshi 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.
