Market context

On 27 May 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will fall into one of several discrete ranges, with settlement determined by Wunderground's historical weather data for that specific station. The market currently shows 0% implied probability across all temperature bands, a technical artefact of how Polymarket's conditional token system initialises contracts before meaningful trading volume arrives. Once traders begin depositing USDC and minting position tokens on Polygon, the probability distribution will reflect genuine expectations about late-May conditions in Shenzhen's subtropical climate.

Shenzhen's late May temperatures are remarkably consistent year-on-year. Historical data from Bao'an station shows daily highs clustering between 29–33°C during this period, with occasional spikes to 34–35°C during heat waves. The 0% reading across all ranges is therefore misleading; it reflects the contract's nascent state rather than any genuine uncertainty about whether temperatures will occur. Comparable May 27 observations from prior years provide a reliable baseline: the station has recorded highs in the 30–32°C band in most recent years, with only rare excursions above 33°C.

Traders should monitor seasonal weather patterns emerging in May 2026, particularly the onset of the pre-monsoon period and any tropical systems developing across the South China Sea. Wunderground's historical database for Bao'an is the sole authoritative source, making data accessibility straightforward once settlement approaches. The settlement window closes at 12:00 UTC on 27 May, giving traders until that point to adjust positions based on morning forecasts and early-day observations.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
