Market context

On 30 May 2026, the highest temperature recorded at Incheon International Airport Station will fall into one of several defined ranges, measured in degrees Celsius. The settlement hinges on historical weather data published by Weather Underground for that specific location and date. Seoul's late-May climate typically sits in the warm-to-hot range; the city's average high in May is around 26°C, though individual days frequently exceed 28°C, with outlier peaks reaching into the low 30s during early heat waves.

The 0% crowd probability suggests traders currently perceive negligible demand for extreme-temperature outcomes, or the market structure itself may not yet reflect typical May variance. Historically, Seoul experiences considerable day-to-day volatility in late spring, driven by shifting monsoon patterns and occasional warm-air advection from the south. Comparable May 30th conditions across prior years show highs ranging from 22°C to 31°C, indicating the settlement range brackets genuine meteorological uncertainty rather than edge-case scenarios.

Traders should monitor the Korean Meteorological Administration's extended forecasts from mid-May onwards, as these typically gain accuracy within two weeks of the target date. Pacific typhoon activity and upper-level ridge positioning over East Asia in late May can materially shift temperature outcomes. Additionally, Incheon Airport Station's specific microclimate—coastal location, urban heat-island effects—may produce readings 1–2°C higher than Seoul's city centre, a detail relevant when cross-checking forecasts against other local stations.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
