Market context

On 26 May 2026, Shenzhen will experience late spring weather as it transitions toward the summer monsoon season. The settlement mechanism relies on the highest temperature recorded at Bao'an International Airport Station, which serves as the official meteorological reference point for the city. Currently, Polymarket prices this contract at 0% YES across all temperature bands, suggesting traders are either awaiting clearer seasonal forecasts or treating this as a placeholder market pending liquidity.

Shenzhen's May temperatures historically cluster between 28–32°C, with occasional peaks above 33°C during heat waves. The city's subtropical climate means late May typically sits between spring and early summer conditions, though the exact range depends on whether the South China Sea monsoon has established itself. Historical data from Bao'an station shows May highs rarely exceed 35°C, making extreme temperature bands less probable than moderate ranges. The 0% pricing across all outcomes reflects the market's current illiquidity rather than genuine uncertainty about whether temperatures will fall within any given band.

Traders should monitor seasonal forecasts from the China Meteorological Administration, which typically issues 30-day outlooks in late April. The onset timing of the southwest monsoon—normally May–June—will be the primary catalyst affecting whether Shenzhen experiences typical late-spring warmth or an earlier shift toward summer heat patterns. Wunderground's historical data for Bao'an station provides the settlement source, so traders should verify the station's operational status and data availability ahead of the resolution window closing on 26 May at 12:00 UTC.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
