Market outcomes
| KBO: Samsung Lions vs. Kiwoom Heroes | 0% YES | 100% NO |
Samsung Lions face Kiwoom Heroes in a Korean Baseball Organisation fixture scheduled for 25 April at 4:00 AM ET. The match represents a regular-season contest within the KBO's competitive landscape, where both franchises compete across a 144-game season. The current 0% implied probability on Polymarket's order book reflects minimal trading activity or positioning rather than genuine assessment of outcome likelihood; such extreme probabilities typically emerge when liquidity is sparse and no counterparty has committed capital to either side.
Historical context suggests KBO regular-season matchups between mid-tier franchises rarely sustain such polarised probabilities once trading begins. Samsung Lions and Kiwoom Heroes have comparable competitive standing within the league, with neither club commanding overwhelming favourites status in head-to-head fixtures. Recent seasons show both teams capable of competitive performances, though specific form trajectories and roster composition changes warrant examination closer to the fixture date. The settlement window extending to 2 May allows substantial time for market repricing as game-day approaches and additional information surfaces.
Traders should monitor roster announcements, injury reports and weather conditions affecting the Seoul-based venue in the days preceding the match. Polymarket's order book will likely see movement once liquidity providers enter the market; the current extreme probability suggests the market has not yet attracted meaningful participation. KBO official sources and Korean sports reporting outlets will provide relevant updates on team preparation and any scheduling changes.
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. 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.
$11K 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 0%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
