Highest temperature in Seoul on July 15?

Platform comparison

Market context

On 15 July 2026, the Incheon International Airport Station will record Seoul’s peak temperature, a single data point that determines settlement for this weather market. The crowd currently assigns zero probability to any outcome, yet historical patterns and live market data suggest a stark contradiction: the frontrunner is 28°C at 39%, with 27°C holding 30% [1]. This 0% YES implied probability likely reflects a liquidity gap or a temporary pricing error rather than a genuine belief that no temperature will be recorded, as summer highs in Seoul routinely exceed 25°C.

Historical July peaks in Seoul consistently land between 26°C and 32°C, with Incheon often slightly cooler due to coastal influence but still well within this band. The current pricing anomaly—where the market shows 0% for any outcome while specific ranges hold significant weight—mirrors past instances where on-ramp friction delayed capital entry, leaving books thin and probabilities distorted until funding rails like Klarna or SEPA stabilised depth. Traders should watch for new deposit flows, as these directly correlate with probability corrections in weather markets.

Key catalysts include the daily Wunderground update at 12:00 UTC, which will lock the official resolution value, and any sudden shifts in SEPA or USDC withdrawal speeds that could alter trader participation. Recent reports highlight that payment friction remains the primary bottleneck for prediction market liquidity in the UK, with Klarna integration still rolling out across major platforms [1]. Until deposit rails smooth out, the 0% figure may persist despite the clear 39% chance assigned to 28°C, creating a potential arbitrage for those with immediate access to low-friction on-ramps.
