Market context

Seoul's maximum temperature on 17 June 2026 will be measured at Incheon International Airport's weather station and reported in Celsius. The settlement hinges on Wunderground's historical weather database, which aggregates hourly readings across the full calendar day. For programmatic traders, this resolves as a discrete categorical outcome—the market bins temperature ranges, and only the bracket containing the actual high triggers resolution.

Mid-June in Seoul typically sees daily highs between 26–28°C, though heat waves can push readings above 32°C. Historical June records at Incheon show extremes ranging from 34°C during anomalous heat events to cooler patterns around 22°C during monsoon-influenced years. The 0% crowd probability suggests traders are either awaiting seasonal forecasts closer to the date or treating this as a calibration market where early positioning carries minimal conviction. Comparable June markets in East Asia have resolved across the full temperature spectrum; the wide range reflects genuine meteorological variability rather than data ambiguity.

Traders monitoring this market should track the East Asian summer monsoon onset timing and any tropical cyclone activity in the Western Pacific during early-to-mid June 2026. South Korea's Meteorological Administration publishes monthly outlooks and 10-day forecasts that typically become actionable 7–10 days before settlement. Automated feeds from Wunderground can be queried via API to validate historical station data and cross-check against Korea Meteorological Administration records, allowing conditional orders to trigger once seasonal models stabilise.

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.
