Market outcomes
| KBO: Samsung Lions vs. SSG Landers | 100% YES | 0% NO |
Samsung Lions face SSG Landers in a Korean Baseball Organisation (KBO) regular season match scheduled for 28 May at 5:30 AM ET. The current order book on Polymarket reflects a 100% implied probability, indicating the market has collapsed to one side with minimal liquidity for contrarian positions. This extreme probability typically emerges when one outcome dominates trader conviction or when insufficient volume has accumulated to establish meaningful two-sided pricing.
The KBO regular season runs from late March through October, with both franchises competing in a 144-game schedule. Historical context shows that regular season matchups between established clubs like Samsung Lions and SSG Landers rarely settle with certainty before game time; such compressed probabilities usually indicate either a data error, a cancelled fixture announcement, or an absence of active trading depth. The settlement window extending to 4 June provides ample time for the game to be played, rescheduled if weather-delayed, or officially cancelled—each scenario carrying distinct resolution implications under the market's tie-resolution rules.
Traders should monitor official KBO announcements regarding fixture status, particularly weather-related postponements common in late May. Injury reports for key players on either roster, published through KBO channels and Korean sports media, could shift underlying match dynamics. The resolution mechanism specifies that cancellations without make-up games or tie results trigger 50-50 settlement, creating tail-risk scenarios distinct from a straightforward home-and-away outcome. Current 100% pricing leaves no margin for these contingencies.
This market settles from the official outcome published at https://www.koreabaseball.com/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "KBO: Samsung Lions vs. SSG Landers" 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.
$3K in lifetime turnover and $0 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.
As of today, traders on Polymarket price this outcome at 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
