Highest temperature in Beijing on July 14?

Platform comparison

Market context

Beijing's highest temperature on 14 July 2026 will be measured at the Capital International Airport Station and resolved against historical weather records. The market currently shows 0% implied probability across all temperature bands, suggesting either incomplete pricing or a data-loading issue rather than genuine consensus that no temperature will be recorded.

July temperatures in Beijing typically peak between 32–36°C, with occasional extremes reaching 38–40°C during heat waves. Historical data from the past decade shows that mid-July highs consistently fall within the 33–35°C range under normal conditions, though the city experienced 40.6°C in June 2022 during an exceptional heat event. The 0% reading across all brackets is anomalous given that some temperature outcome is certain to occur; this suggests the market may not yet reflect typical seasonal patterns or that traders are awaiting clearer forecast data as the date approaches.

The key catalyst will be the East Asian summer monsoon pattern and any high-pressure systems developing over northern China in early July 2026. The China Meteorological Administration typically issues 10-day forecasts by early July that would clarify whether conditions favour above-average or near-average temperatures. Any significant heat dome or tropical cyclone activity in the region could shift outcomes materially. Traders should monitor whether the crowd begins pricing realistic temperature ranges once seasonal forecasts solidify, as the current flat 0% reading leaves substantial value in whichever band ultimately contains the recorded high.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Who Will Win 2026. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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 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.
