Trade: Lee Jae-myung impeached before 2027?

Market context

The South Korean National Assembly could formally impeach Lee Jae-myung, the Democratic Party leader and 2022 presidential candidate, before the end of 2026. Impeachment requires a two-thirds supermajority vote in the 300-seat legislature. Lee currently faces multiple legal challenges, including convictions on charges related to campaign finance violations and abuse of power, though these remain subject to appeal. The market is pricing impeachment as a low-probability event at 9% implied probability on Polymarket's order book, reflecting the substantial political and procedural barriers involved.

South Korea's recent impeachment history provides context for assessing this probability. President Park Geun-hye was impeached in December 2016 following the Choi Soon-sil scandal, with the Constitutional Court upholding the decision in March 2017. However, impeaching a major opposition figure rather than a sitting president presents different political dynamics. The ruling party would need to secure supermajority support, which typically requires cross-party cooperation. Lee's position as opposition leader rather than sitting president means impeachment would be a more extraordinary political move, historically less common than removing an incumbent executive.

Traders should monitor developments in Lee's ongoing legal cases, particularly Constitutional Court rulings on his convictions, and any shifts in National Assembly composition. The December 2026 parliamentary elections could alter the political calculus significantly. Additionally, any major political crisis or scandal involving Lee could accelerate impeachment discussions, though the high procedural threshold means sustained political will across party lines would be necessary for passage before the settlement deadline.

How this market resolves

Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.

How active is this market?

$9K in lifetime turnover and $20K of resting liquidity puts this market in the below the median by volume for south korea contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.

Last 24 hours alone saw $1K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.

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

YES / NO share

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.

CLOB

Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.

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.
