Trade: How many South Korean mayor/governor races will DP win?
Resolution criteria on PolyGram: South Korean local elections are scheduled to be held on June 3, 2026. This market will resolve according to the number of Mayor and Governor elections for South Korea’s upper-level local governments won by the Democratic Party (DP) during these elections. A candidate will be considered an official candidate of a party if they are officially nominated by that party and are registered for the relevant election in affiliation with that party. Independent candidates will not count for any party.

Market context
South Korea will hold local elections on 3 June 2026 for mayors and governors across its metropolitan cities and provinces. The Democratic Party's performance in these races will determine the settlement of this market, with the crowd currently pricing a 41% probability of the DP winning a specified threshold of these upper-level positions. The order book on Polymarket reflects this implied probability through active trading, with the current price reflecting expectations about DP competitiveness against the ruling People Power Party and other challengers.
Historical context matters considerably for interpreting this probability. In the 2022 local elections, the PPP secured a decisive victory, winning 10 of 17 mayor and governor races, whilst the DP won 6. That result reflected broader political momentum following Yoon Suk-yeol's presidential election victory in 2021. The DP has traditionally alternated control of local governments with the ruling party in South Korea's competitive two-party system, though recent elections have shown the PPP's structural advantages in provincial areas. The 41% implied probability suggests traders expect the DP to underperform its 2022 baseline, potentially reflecting the PPP's continued strength or internal DP organisational challenges.
Traders should monitor several developments ahead of the June 2026 vote. Presidential approval ratings and economic conditions will shape the electoral environment significantly. Candidate nominations by both major parties, typically finalised in early 2026, will clarify competitive dynamics in individual races. Any major policy announcements or political crises between now and the election could shift momentum, particularly regarding economic performance or governance issues that resonate in local campaigns.

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 "How many South Korean mayor/governor races will DP win?" are the same as any other PolyGram political 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.
- Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
- Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
- 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.
- Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
- 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.
- 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?
$1 in lifetime turnover and $3K 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 $1 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 under a month — fresh enough that information asymmetry remains a real factor.
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.
