Trade: Will Han Duck-soo be sentenced to prison before 2027?

Market context

Han Duck-soo, South Korea's Prime Minister and former Acting President, faces multiple criminal investigations stemming from his December 2024 martial law declaration and subsequent political manoeuvres. Prosecutors have charged him with abuse of power, obstruction of constitutional processes, and failure to promulgate legislation during the constitutional crisis that followed President Yoon Suk-yeol's short-lived martial law order. The case centres on whether Han's actions as Acting President constituted criminal conduct warranting imprisonment rather than fines or suspended sentences.

South Korean political figures have historically received prison sentences in comparable cases, though outcomes vary substantially. Former Presidents Lee Myung-bak and Park Geun-hye both received custodial sentences for corruption and abuse of power charges, though Park's sentence was later suspended. However, some high-ranking officials have avoided prison through appeals or presidential pardons. The current 100% implied probability on Polymarket's order book reflects confidence that Han will receive at least some prison sentence, though this may overweight the certainty of conviction versus the possibility of suspended sentences or successful appeals.

Key catalysts include the Seoul Central District Court's trial schedule, with hearings ongoing through 2025 and a verdict expected within the settlement window. Prosecutors have signalled they will seek a substantial prison term. Watch for developments in parallel cases against other officials involved in the martial law declaration, as these may influence sentencing precedent. Any presidential pardon announcement would effectively resolve this market to "No" regardless of sentencing, adding political risk to the current pricing.

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 to trade this market step by step

The mechanics for trading "Will Han Duck-soo be sentenced to prison before 2027?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
3. Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
4. Size your position. If you stake 100 USDC at 100% YES, you'll receive shares that pay $100 if YES resolves true — a 0% gross return. If NO resolves, your shares are worth $0.
5. Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
6. Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.

How active is this market?

$42K in lifetime turnover and $0 of resting liquidity puts this market in the around the median by volume for world contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for 6 months — the price has had time to stabilise as new information arrived.

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.

Frequently asked questions

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.
