Lee Jae-myung impeached before 2027?

Resolution Criteria

This market will resolve to "Yes" if the President of South Korea, Lee Jae-myung, is formally impeached by the South Korean National Assembly by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." For this market to resolve to "Yes" it is only necessary that the National Assembly propose and approve a motion of impeachment against Lee Jae-myung, regardless of whether the Constitutional Court later upholds the impeachment. The primary resolution source for this market is official information from the South Korean government, however a consensus of credible reporting may be used.

The prediction market for Lee Jae-myung being impeached before 2027 sits at a heavily skewed distribution, with the 'No' outcome drawing the overwhelming majority of market volume. The market resolves 'Yes' only if the South Korean National Assembly formally approves an impeachment motion against President Lee Jae-myung by 31 December 2026, regardless of any subsequent Constitutional Court ruling. Official South Korean government sources serve as the primary resolution authority.

Market structure

This is a binary market with two outcomes: 'Yes' (impeachment approved by the National Assembly before the deadline) and 'No' (impeachment not approved). Volume is heavily concentrated on the 'No' outcome. Resolution requires only a National Assembly vote approving an impeachment motion — Constitutional Court confirmation is not required. The deadline is 31 December 2026, with official South Korean government sources as the primary resolution source and credible press consensus as a fallback.

Background

Lee Jae-myung, leader of the Democratic Party of Korea, won the June 2025 snap presidential election following the impeachment and removal of Yoon Suk-yeol, whose short-lived declaration of martial law in December 2024 triggered a constitutional crisis. Lee had previously faced significant legal jeopardy as an opposition leader, including convictions and ongoing appeals related to electoral law violations and other charges. His transition from defendant to president represents one of the more turbulent arcs in recent South Korean political history. South Korea's constitution permits the National Assembly to impeach a sitting president with a two-thirds majority, a mechanism used twice in recent memory — against Park Geun-hye in 2016 and Yoon Suk-yeol in 2024.

Key factors

Several structural factors bear on this market's resolution. First, the composition of the National Assembly is critical: impeachment requires a two-thirds supermajority, meaning the opposition would need to either hold that threshold or attract cross-party support. Lee's Democratic Party and its allies held a commanding legislative majority entering his presidency, making a hostile supermajority difficult to assemble within the 2026 timeframe. Second, Lee's outstanding legal cases — including appeals against prior convictions — could generate political pressure, but judicial outcomes and parliamentary action are distinct processes. Third, a domestic political crisis, scandal, or dramatic policy failure could shift the legislative calculus, though such events are by definition unpredictable. Fourth, the speed of South Korean political change, demonstrated by the Yoon episode, means circumstances can shift rapidly. Fifth, any impeachment motion would require political will among a sufficient bloc of legislators, which would depend on party discipline, public opinion, and coalition dynamics evolving through 2026.
