Market outcomes
| KBO: Kia Tigers vs. Lotte Giants | 100% YES | 0% NO |
The Korean Baseball Organisation (KBO) will host a matchup between the Kia Tigers and Lotte Giants on 9 May at 4:00 AM ET. The current order book on Polymarket reflects a 100% implied probability for resolution, suggesting either exceptionally high confidence in the game's occurrence or minimal liquidity at the current price. With the settlement window extending to 16 May, traders have a week-long window to observe whether the game proceeds as scheduled or faces postponement due to weather or other operational factors.
Historical context for KBO games shows that whilst cancellations remain rare, weather-related postponements occur periodically during the Korean spring season. The Tigers and Giants are mid-table competitors in the 2025 KBO season, with neither team commanding exceptional form that would justify extreme confidence in a particular outcome. The extreme probability reading likely reflects the binary nature of the market structure—where a postponed game keeps the market open rather than resolving immediately—rather than genuine certainty about match completion.
Traders should monitor KBO official announcements regarding venue conditions and team roster updates in the days preceding the fixture. The Tigers' recent performance against the Giants, typically competitive matchups, provides limited predictive value given the flat probability structure. Any weather alerts for the Seoul metropolitan region or unexpected player availability issues could shift market sentiment, though the current illiquidity at extreme prices suggests limited trading activity has occurred since market inception.
The KBO League is the highest level professional baseball league in South Korea, consisting of ten teams. The KBO League was founded with six franchises in 1982 and is the most popular sports league in South Korea. The Kia Tigers are the most successful team, having won 12 of the 44 championships.

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: Kia Tigers vs. Lotte Giants" 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 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.
