Trade: Yoon out of custody before 2027?
Resolution criteria on PolyGram: This market will resolve to "Yes" if President of South Korea Yoon Suk Yeol is released from custody by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". If Yoon is released but remains under house arrest, the market will still resolve to "Yes". If Yoon is released on parole, bond, or any other condition that results in them leaving state custody, the market will resolve to "Yes". Transporting Yoon to another location of custody (e.g., a different prison, court, or hospital within the correctional system) will not suffice to resolve this market to "Yes".

Market context
President Yoon Suk Yeol of South Korea faces multiple criminal investigations and has been detained on charges including insurrection related to his December 2024 martial law declaration. The central question for this market is whether he will be released from state custody—whether through acquittal, case dismissal, or conditional release such as parole or bail—before the end of 2026. The current order book on Polymarket prices this outcome at 7% probability, reflecting substantial scepticism that Yoon will exit custody within the settlement window.
South Korea's legal system provides limited historical precedent for high-ranking sitting or recently-departed presidents facing insurrection charges. Former presidents have faced prosecution, but the severity and political sensitivity of insurrection allegations creates uncertainty around both trial duration and judicial outcomes. The Constitutional Court's December 2024 decision to proceed with Yoon's impeachment trial rather than dismiss it outright signals institutional willingness to pursue the case, though impeachment and criminal proceedings operate on separate timelines. International observers note that South Korean courts have historically required substantial evidence for conviction on insurrection charges, a high bar that may extend proceedings.
Key catalysts include the Constitutional Court's impeachment verdict (expected mid-2025), the Seoul Central District Court's handling of detention extension hearings, and any appellate decisions on his initial arrest warrant. Recent reporting from Reuters and local outlets indicates prosecutors are pursuing multiple charges beyond insurrection, including abuse of power, which could fragment the legal process across different courts. A trader monitoring this market should track court scheduling announcements and any shifts in prosecutorial strategy, as these directly influence the probability of release before end-2026.

How active is this market?
$10K in lifetime turnover and $14K of resting liquidity puts this market in the below the median by volume for politics contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $37 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 6 months — long enough that the order book is mature and price is well-anchored to fundamentals.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms

- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
