Market context

On 26 May 2026, Beijing's highest temperature will be recorded at the Capital International Airport Station and fall into one of several defined ranges. The market currently prices all temperature brackets at 0% probability on Polygon, suggesting either thin liquidity or a settlement mechanism awaiting activation. Traders holding conditional tokens will need to wait until after 12:00 UTC on that date for Wunderground's historical data to finalise before any resolution occurs.

Beijing's late May temperatures typically range between 25–32°C, with occasional peaks above 33°C during early heat waves. Historical records from May 2023 and 2024 show highs clustering around 28–30°C, though the city experienced 35°C+ readings in late May during 2018 and 2020. The current zero-probability pricing reflects the market's nascent state rather than any meteorological certainty; comparable weather markets on Polymarket usually see meaningful price discovery only within 7–10 days of settlement as forecast models converge.

The primary catalyst for price movement will be seasonal weather pattern updates from China's Meteorological Administration and international forecast models (GFS, ECMWF) in early May 2026. Any developing high-pressure system or early monsoon activity could shift expectations significantly. Traders should monitor whether spring 2026 establishes itself as warmer or cooler than the 2020–2024 baseline; anomalies in April temperatures often correlate with May outcomes. The USDC settlement mechanism on Polygon means positions remain liquid until resolution, though slippage may widen if volume remains sparse.

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.
