Market context

On 4 June 2026, the highest temperature recorded at Shenzhen Bao'an International Airport will determine which range wins this market. The crowd currently assigns zero probability to any outcome, suggesting either extreme uncertainty or insufficient liquidity to establish consensus pricing. Shenzhen's early June climate sits at the threshold between late spring and summer onset, with daily highs typically ranging between 28 and 33 degrees Celsius, though heat waves can push readings several degrees higher.

Historical temperature records from Shenzhen show June peaks clustering around 32–34 degrees Celsius in typical years, with occasional excursions to 35 degrees or beyond during anomalous warm spells. The 0% implied probability reflects the market's current inability to settle on any single range rather than genuine forecasting conviction that temperatures will fall outside normal bounds. Traders should examine the specific temperature brackets offered; if the ranges are narrowly constructed around the 30–34 degree band, the zero reading likely indicates missing price discovery rather than a genuine outlier event.

Catalysts entering June 2026 include the onset of the East Asian summer monsoon system, which typically brings moisture and occasional cloud cover that moderates peak temperatures. The South China Sea's sea surface temperatures and any developing tropical systems will influence whether Shenzhen experiences typical early-summer heat or cooler, cloudier conditions. Current seasonal forecasts from meteorological services should be cross-referenced against the specific temperature brackets available; the absence of crowd engagement suggests traders may be waiting for clearer range definitions before committing capital.

Methodology

This page reviews Highest temperature in Shenzhen on June 4? across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at Who Will Win — the application we operate, where you trade directly against the Polymarket order book at 0% fees.

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.
