Highest temperature in Shenzhen on July 14?

Platform comparison

Market context

Shenzhen's mid-July heat will be measured against historical benchmarks on 14 July 2026, with the settlement hinging on the single highest temperature recorded at Bao'an International Airport Station throughout that calendar day. The current 0% crowd probability across all temperature bands suggests either extreme uncertainty about which range will resolve, or traders awaiting clearer atmospheric forecasting as the date approaches. On Polymarket, this contract trades as conditional tokens on Polygon, with USDC collateral backing each outcome bracket—meaning the probability distribution across temperature ranges currently reflects no consensus favourite.

Shenzhen's July climate is remarkably consistent. Historical data from Bao'an shows July highs typically cluster between 32–34°C, with extreme readings rarely exceeding 36°C even during heat waves. The 2019 and 2023 July periods recorded peaks of 34.5°C and 33.8°C respectively, establishing a reliable baseline. The 0% reading across all ranges is anomalous and likely reflects low trading volume rather than genuine uncertainty about whether temperatures will fall within normal seasonal bounds.

Traders should monitor the East Asian summer monsoon forecast from June onwards, particularly any advisories from the China Meteorological Administration regarding heat domes or tropical systems that might suppress temperatures. Bao'an's coastal location moderates extremes compared to inland Shenzhen districts, a factor worth noting when interpreting settlement data. The Wunderground historical database will be the sole arbiter, making data access and timestamp verification critical before the 12:00 UTC settlement window closes on 14 July.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

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'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.

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.

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.
