Market context
Seoul is entering its peak monsoon period, where July typically delivers intense, short bursts of rain that cool the air rather than sustain extreme heat. Historical data shows daily highs in Seoul during July usually range between 25°C and 30°C, with average highs hovering around 27°C to 28°C, while humidity pushes the "feels like" temperature higher but rarely sustains record-breaking dry heat [1][4]. The current 0% crowd-implied probability for a specific high-temperature range aligns with these patterns, as late July and August are statistically more prone to the most sustained heatwaves, whereas early July remains dominated by the Jangma rainy season that limits peak temperatures [2][3].
Traders should monitor the Korea Meteorological Administration’s short-range forecasts for any sudden shifts in cloud cover or wind patterns that could temporarily suppress rainfall and allow temperatures to spike [5]. The market is leaning on the absence of major heat-related catalysts, such as official declarations of extreme heat warnings or unusual atmospheric pressure systems, which have not materialised in recent news [8]. While the Sinchon Water Gun Festival in late July may increase local humidity, it does not typically drive sustained high temperatures, and no recent campaign-finance disclosures or political debates have been linked to weather anomalies that would alter this trajectory [2]. The settlement window ending on 3 July 2026 captures the tail end of the rainy season, making extreme heat unlikely without a clear, unforecasted atmospheric shift.

FAQ
- How accurate are political prediction markets?
- Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.
- What resolution source is used for elections?
- Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.
- Can prediction markets influence election outcomes?
- Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.
- How fast do political markets react to news?
- High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.
- Which political events have the biggest volume?
- US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
