Highest temperature in Beijing on July 16?

Platform comparison

Market context

Beijing’s summer heat on 16 July 2026 is the real-world event determining this contract, with the settlement tied to the peak temperature recorded at Beijing Capital International Airport Station. The market currently prices the YES outcome at 0%, implying the crowd expects the temperature to fall outside the defined range, though the exact range isn’t specified in the prompt. This near-zero probability is unusual for a mid-July date in Beijing, where historical data shows summer temperatures frequently exceed 30°C, often reaching 35–38°C during heatwaves [1].

Historically, Beijing’s July highs cluster between 31°C and 37°C, with several years recording peaks above 38°C, such as in 2023 and 2024. A 0% implied probability suggests traders believe the temperature will be either significantly lower or higher than the market’s threshold, possibly due to an unusually cool forecast or an extreme heat spike not yet priced in. Comparable cases from recent summers show that even with monsoon-driven cloud cover, daytime highs rarely dip below 28°C in mid-July [1].

Traders should monitor the daily Wunderground update for ZBAA at 12:00 UTC, which serves as the official resolution source, and watch for any sudden shifts in the National Meteorological Centre’s heatwave bulletins. While no specific announcement is pending, the timing of the settlement—ending precisely at 12:00 UTC on 16 July—means the market will resolve on the day’s actual peak, not a forecast. On-chain mechanics on Polygon, using USDC and conditional tokens, allow instant position adjustments as the day unfolds, making real-time weather data the only catalyst worth tracking.

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

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 PolyGram 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.
