There is a significant 'denominator uncertainty' risk. While the resolution rule is clear (counting all by-election seats on June 3), currently only 'at least four' are confirmed. The total number of contested seats could increase due to court rulings or resignations before the deadline. Since the options are absolute numbers (e.g., 10+), if the final total of contested seats is lower than an option's threshold, that outcome becomes impossible. This variability heavily impacts the probability of each bracket.

This is a mid-niche market focused on South Korean domestic politics. While standard for observers of Asian geopolitics or the Korean market, it requires specific regional knowledge (e.g., Korean party structures, by-election dynamics) that is typically outside the scope of general global prediction market participants.

April 26, 2026 - April 29, 2026, the price of the '10+' option plummeted from 83.35c to 62.35c, while the '6-7' option surged from 0.25c to 24.4c. The reason is that as local elections approach, the finalized number of MPs resigning to run may be lower than previous extremely optimistic market expectations, reducing the total available seats and making 6-7 seats a new high-probability range. April 10, 2026 - April 13, 2026, the price of the '10+' option surged from 25.2c to 46.8c, while the '8-9' option plummeted from 73.6c to 41.2c. Reason: The market further adjusted its expectations upward regarding the total number of by-election seats caused by MPs resigning for local elections, making 10+ seats the new baseline for the DP. March 10, 2026 - March 13, 2026, the price of the '10+' option surged from 36.7c to 67.9c, while the '8-9' option plummeted from 49.6c to 24.0c. Reason: As the June local elections approach, confirmations of incumbent MPs resigning to run for local executive positions (Mayor/Governor) have likely increased the expected total number of by-election seats, shifting the probability of the DP winning 10+ seats from 'possible' to the 'baseline scenario'.
