Market context

Seoul's weather on 28 May 2026 will be measured at Incheon International Airport Station, with the settlement hinging on the single highest temperature recorded across all daylight and overnight hours. The market resolves based on historical data pulled from Weather Underground's daily archive, requiring traders to cross-reference Celsius readings from a specific monitoring station rather than relying on city-centre forecasts or alternative weather networks.

Late May in Seoul typically sits within the 22–28°C range, though anomalies occur. Historical data from the Korea Meteorological Administration shows that May temperatures at Incheon have occasionally spiked to 30°C or exceeded 32°C during early heat waves, whilst cooler years have peaked below 20°C. The 0% crowd probability suggests either extreme confidence in a specific temperature band or insufficient liquidity; traders building conditional orders or automated monitoring systems should flag this as a data-sparse market where historical variance matters more than consensus.

Programmatic traders should note that Weather Underground's historical archive updates with a lag, typically confirming final readings within 24–48 hours after the settlement window closes. Monitoring South Korean meteorological forecasts from mid-May onwards will signal whether ridge-building high pressure or monsoon moisture patterns are establishing themselves. The resolution dependency on a single airport station means localised weather events—thunderstorms or urban heat effects—could shift outcomes; cross-checking against Seoul's broader regional forecasts will help calibrate position sizing before the event date.

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.
