Market outcomes

KBO: SSG Landers vs. Kiwoom Heroes 50% YES50% NO

Market context

The SSG Landers face the Kiwoom Heroes in a regular-season KBO matchup scheduled for 19 May at 5:30 AM ET. The current order book on Polymarket reflects a 50-50 split, indicating traders see genuine uncertainty between these two mid-table competitors. The settlement window extends to 26 May, providing a buffer for any postponements common in Korean baseball during late spring weather patterns.

Both franchises have shown inconsistent form through the 2025 season, with neither establishing clear dominance in head-to-head records. Historical matchups between these sides typically produce close contests, and the even probability distribution reflects this parity. Recent KBO seasons have demonstrated that mid-season games between comparable teams rarely favour one side decisively unless injury or roster changes create material advantages.

Traders should monitor roster announcements and weather forecasts in the days preceding the fixture, as the early morning ET kickoff suggests potential weather sensitivity in Seoul. Any late-breaking injuries to key batters or pitchers for either side could shift the probability meaningfully. Official KBO injury reports and team lineups, typically released 24 hours before first pitch, will provide concrete data for position adjustment. Precipitation forecasts for Seoul on 19 May may also influence game conditions and pitcher effectiveness, particularly for the Landers' or Heroes' starting rotation.

How to trade this market step by step

The mechanics for trading "KBO: SSG Landers vs. Kiwoom Heroes" are the same as any other PolyGram sporting 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.

  1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
  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 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.
  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?

$0 in lifetime turnover and $48 of resting liquidity puts this market in the below the median by volume for sports 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 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.
