If this event resolves 'Yes', it would be a massive geopolitical black swan. The South Korean Won (KRW) and South Korean equities (e.g., ETF EWY) would face immediate, devastating crashes. Safe-haven assets like Gold and the US Dollar would surge. Given South Korea's critical role in the global semiconductor supply chain, global equities (especially Nasdaq and S&P 500) would suffer severe hits. Oil prices would also react to regional instability. This market serves as a direct hedge against this specific catastrophic risk.

There is a divergence. Mainstream military and geopolitical experts widely consider the probability of a full-scale North Korean invasion to be near zero (<1%), as it would equate to regime suicide. However, the prediction market assigns an almost 7% probability, significantly overpricing this tail risk. This divergence typically stems from retail traders overreacting to localized geopolitical frictions (e.g., missile tests, border skirmishes) and misinterpreting them as precursors to all-out war.
