Highest temperature in Seoul on July 13?

Platform comparison

Market context

Seoul is bracing for peak summer heat on 13 July 2026, with the Incheon International Airport station expected to record daily highs consistent with recent extreme trends. Historical data shows July highs in Seoul typically range between 29°C and 33°C, rarely exceeding 33°C, though 2025 saw the second-hottest July since 1973 with an average of 27.1°C nationwide [4][6]. The market’s 0% YES probability for any outcome suggests a likely mispricing, as Polymarket data indicates 32°C is the leading outcome at 42–47% probability, followed by 33°C at 28–32% [1].

Recent precedent underscores the volatility: Seoul recorded 22 consecutive “tropical nights” in July 2025, breaking a century-old record with overnight temperatures above 25°C [2][3]. This surge aligns with South Korea’s second-hottest July ever, driven by persistent heatwaves that pushed Hongcheon to a national record of 41.0°C in 2023 [4][5]. Traders should monitor the Korea Meteorological Administration’s daily forecasts and Wunderground’s real-time updates for the Incheon station, as sudden shifts in monsoon patterns or heat dome intensity could alter the settlement range [2][5]. No major announcements are scheduled, but the dependency on live weather data means outcomes remain fluid until the 12:00 UTC settlement deadline.

FAQ

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
