Yes refers to: Ending Jun 4, 2029
Short Answer
Both the model and the market expect South Korean President Lee Jae-myung to serve their full term, with no compelling evidence of mispricing.
1. Market Behavior & Drivers
This prediction market exhibits a stable, sideways price trend, indicating consistent sentiment over the observed period. The probability of President Lee Jae-myung serving a full term has traded within a relatively narrow 9.1 percentage point range, from a low of 81.0% to a high of 90.1%. The market opened at 89.0% and is currently trading at its peak of 90.1%, showing a slight positive drift but no definitive breakout. The price level of 81.0% has acted as a clear support floor, while the current price of 90.1% represents the resistance ceiling for this market's history.
Given that no specific news context is available, it is not possible to attribute the modest price fluctuations, such as the temporary dip to the low 80s, to any particular real-world event. The total volume of 1,775 contracts is moderate for a long-term political market. The sample data points show price swings occurring on zero volume, which suggests that some price changes may reflect thin trading activity rather than a shift in broad market conviction. Periods of low volume during price moves can indicate that the market is not reacting with strong consensus to new information.
Overall, the chart suggests that market participants hold a strong and steady belief that the outcome will be YES. The consistent trading in the 80% to 90% range indicates high confidence that has not been significantly shaken. The price action remaining well above 80% throughout its history points to a stable consensus, with the current price at an all-time high reflecting the most optimistic sentiment recorded in the market to date.
- Supreme Court ruling on Lee Jae-myung's corruption cases faces high uncertainty.

5. When Will South Korea's Supreme Court Rule on Lee Jae-myung?
| Current Trial Status | Indefinitely postponed at Seoul High Court [1] |
|---|---|
| Presidential Immunity Impact | Trials likely suspended until June 2029 if elected president [2] |
| Supreme Court Trial Duration Trend | Increasing, potentially delaying final ruling beyond 2029 [3] |
A final verdict timeline for Lee Jae-myung's most advanced corruption cases remains highly uncertain. The trials concerning the Daejang-dong development and Seongnam FC bribery allegations are currently indefinitely postponed at the Seoul High Court. This means these cases have not yet advanced to the Supreme Court for a final appeal, a delay partly attributed to existing judicial vacancies [1].
Presidential immunity significantly impacts any potential Supreme Court verdict timeline. Should Lee Jae-myung be elected president, criminal trials against him, including the Daejang-dong and Seongnam FC cases, would likely be suspended until the completion of his presidential term [2]. Given a prediction market resolution date of June 4, 2029, for a full presidential term, any Supreme Court verdict would therefore not occur before this date, as his trials would be halted during his presidency [2].
General trends indicate increasing durations for high-profile Supreme Court appeals in South Korea. Even without considering the potential impact of presidential immunity, high-profile appeals, especially at the Supreme Court level, are experiencing longer durations [3]. An April 2026 source suggests that if a final ruling were further delayed by the Supreme Court, it might be possible for Lee Jae-myung to run for the 2029 presidential election without a finalized judgment, implying a Supreme Court process could extend beyond 2029 [3]. Consequently, providing a definitive projection for a Supreme Court verdict within a specific timeframe is challenging due to ongoing delays and the increasing average duration of such trials.
6. What Internal Factionalism Impacts the Democratic Party's Stability?
| DP National Assembly Seats | 175 of 300 (2024-2028 term) [1] |
|---|---|
| Internal Factionalism | Active between pro-Lee and anti-Lee/pro-Jung groups [2] |
| Public Approval (vs. PPP) | 2x approval compared to People Power Party (March 2026) [3] |
The Democratic Party (DP) maintains a significant majority in the National Assembly with 175 out of 300 seats for the 2024-2028 term, yet it is marked by persistent internal factionalism [1]. Key divisions exist between 'pro-Lee' and 'pro-Jung' (anti-Lee) groups, which have clashed over issues such as the Gongchumoe's independence in February 2026 [4], a Supreme Council By-Election in December 2025 [5], and special counsel recommendations in February 2026 [6]. Even within the pro-Lee faction, discord emerged when it turned against an influential media figure in March 2026 [2], indicating complex and shifting internal dynamics. Additionally, the party experienced backlash following a merger proposal in January 2026 [7].
Despite strong public approval, specific events could trigger impeachment support within the DP. The Democratic Party maintained a strong public standing with '2x approval' compared to the People Power Party in March 2026 [3]. However, the party's existing internal fissures could be significantly exacerbated if President Lee Jae-myung's approval rating were to drop below 25% or if a new major scandal were to emerge. Such circumstances could dramatically empower anti-Lee factions and prompt moderate pro-Lee members to reconsider their loyalty. This shift could provide the necessary impetus for at least 29 DP lawmakers to publicly support an opposition-led impeachment motion, especially if their continued association with an unpopular or embattled leader jeopardizes their own political futures or the party's broader reputation.

7. What Are the Legal Challenges for Lee Jae-myung's Family?
| Wife's Corporate Card Fine | 1.5 million won (first instance ruling, May 12, 2025) [1] |
|---|---|
| Wife's Election Act Case | Acquitted, prosecutors appealed [2] |
| Son's Prostitution Allegations | Under police reinvestigation since January 2023 [3] |
Kim Hye-kyung faces two distinct legal challenges, including a recent fine. Lee Jae-myung's wife, Kim Hye-kyung, received a 1.5 million won fine (approximately $1,090) in a first instance ruling as of May 12, 2025, for the alleged misuse of a Gyeonggi Province government corporate card [1]. Additionally, she was initially acquitted of charges related to violating the Public Official Election Act, but prosecutors have since appealed this decision [4].
Lee Dong-ho is currently under reinvestigation for prostitution allegations. Lee Jae-myung's son, Lee Dong-ho, is facing a police reinvestigation concerning prostitution allegations that first surfaced in December 2021 [3]. While an earlier inquiry in October 2022 cleared him of illegal gambling and forwarded the prostitution allegations without charges, new evidence emerged in January 2023, prompting the current reinvestigation of the prostitution claims [5].
No clear precedent exists for family conviction triggering presidential impeachment. Available sources do not provide a clear precedent where a finalized criminal conviction of a president's immediate family member directly led to a successful impeachment vote in the National Assembly. Previous impeachment cases, such as that of President Park Geun-hye, centered on broader political scandals and influence peddling by a close confidante, rather than a conviction involving a direct family member [6].

8. How Does South Korean Presidential Immunity Affect Lee Jae-myung's Cases?
| Indictment Date | November 19, 2024 [1] |
|---|---|
| Immunity Constitutional Article | Article 84 [2] |
| Effect on Ongoing Trials | Suspended and statute of limitations tolled [3] |
Lee Jae-myung was indicted for corporate card misuse in November 2024. On November 19, 2024, he was indicted for alleged misuse of corporate credit cards and other offenses during his tenure as Gyeonggi governor. The charges include alleged breach of trust, bribery, and violation of the Public Official Election Act, stemming from accusations of using provincial government corporate cards for personal expenses and demanding the Gyeonggi provincial government cover his court fees in a separate election law violation trial. This indictment confirmed that prosecutors acted within the applicable statute of limitations for these specific charges at that time [1].
A presidential election would suspend Lee Jae-myung's criminal trials. Should Lee Jae-myung be elected president, South Korea's Constitution Article 84 dictates that a president cannot be prosecuted for criminal offenses during their tenure, with the sole exceptions being insurrection or treason [2]. In such a scenario, any ongoing criminal trials against him for general offenses would be indefinitely suspended until his presidential term concludes [3].
The statute of limitations would also pause during a presidential term. Crucially, the statute of limitations for offenses for which a president cannot be prosecuted is suspended, or tolled, during their tenure [3]. This means the legal countdown for bringing new charges or continuing with current ones would pause. Consequently, this tolling mechanism could allow for the potential resurgence of existing cases or the initiation of new, politically damaging indictments after his presidency, should sufficient evidence emerge and the original statute of limitations not have fully run out prior to his term [3].
9. What is the Constitutional Court's threshold for presidential impeachment in South Korea?
| Roh Moo-hyun Impeachment Verdict | Rejected, violations not "grave" enough [1] |
|---|---|
| Park Geun-hye Impeachment Verdict | Upheld, due to "grave and continuous violations" [1] |
| Lee Jae-myung Current Charges | Bribery, breach of trust, development project scandals [2] |
The Constitutional Court of Korea requires grave violations for presidential impeachment. The Court has established a high judicial threshold, mandating "grave violations" of the Constitution or laws that profoundly betray public trust and are irreconcilable with the presidential office [1]. In 2004, the Court rejected the impeachment of President Roh Moo-hyun, ruling that while some election law violations might have occurred, they did not amount to "grave violations" sufficient to justify removal, emphasizing that not every legal infraction warrants impeachment [1].
Park Geun-hye's impeachment established severe, continuous violations. The Constitutional Court upheld the impeachment of President Park Geun-hye in 2017 due to "grave and continuous violations" of the Constitution and laws [1]. Her actions involved extensive abuse of power, coercion, bribery, and the disclosure of state secrets through her confidante [3]. The Court found that Park's conduct constituted a fundamental breach of her constitutional duties, specifically violating principles of representative democracy, the rule of law, and public trust. The severity and continuity of these actions were crucial factors in the Court's determination that her behavior was irreconcilable with her presidential office and warranted removal [4].
Lee's charges require a thorough legal assessment against this threshold. Current charges against President Lee Jae-myung include accusations of bribery, breach of trust, and involvement in various development project scandals, including allegations related to a land development scandal and illegal remittances to North Korea [2]. Whether these charges would meet the judicial threshold for impeachment, as established by the Constitutional Court's past rulings, would depend on a thorough legal assessment by the Court, scrutinizing the nature, gravity, and continuity of any proven violations and their impact on public trust and the constitutional order [2].
