Analysis

This probability reflects traders' assessment that South Korea's opposition Democratic Party (DP) will win 10 or more seats in upcoming by-elections. The 81% confidence level suggests markets view a substantial DP victory as likely. The market pricing reflects the DP's recent polling strength and historical performance in by-elections, which often serve as referendums on the ruling party. The main factors pushing this probability upward are favorable public sentiment toward the opposition and typical mid-term electoral dynamics. Downward pressure could come from unexpected governing party momentum or voter turnout patterns favoring the ruling coalition. The probability will resolve once by-election results are officially counted and certified by South Korean election authorities. Current market volume on related contracts remains modest, suggesting limited real-money validation of these price levels.

  • DP's recent polling position relative to the ruling PPP in national surveys
  • Historical turnout and seat distribution patterns in South Korean by-elections over the past decade
  • Public approval ratings for the current administration and opposition leadership
  • Timing of the by-elections relative to major political events or policy announcements
  • Official vote counts and seat allocations as reported by South Korea's National Election Commission

Lateral coverage

Thin contract — here's where the deeper coverage is.

This page aggregates 2 contracts (85% headline). At low contract count, the price reflects two participants’ opinions, not a market consensus. The links below are heavier related questions where the orderbook signal is real.

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
