Market outcomes
| Shanxi Loongs vs. Zhejiang Lions | 0% YES | 100% NO |
The Chinese Basketball Association fixture between Shanxi Loongs and Zhejiang Lions takes place on 10 May at 7:35 AM ET. The current order book on Polymarket shows zero probability assigned to a Shanxi victory, suggesting either overwhelming confidence in a Zhejiang win or minimal trading activity establishing a price. With the settlement window extending to 17 May, there remains a seven-day buffer for game postponement or cancellation contingencies, though CBA fixtures typically proceed as scheduled absent extraordinary circumstances.
Historical context for CBA matchups reveals substantial volatility in regular-season outcomes, particularly when teams face fixture congestion or roster adjustments. The 0% implied probability reflects either definitive pre-match information regarding team composition or extremely thin order book depth at the YES side. Comparable scenarios in Asian basketball markets show that such extreme probabilities often persist when one side commands clear informational advantage or when trading volume concentrates entirely on the opposing outcome.
Traders should monitor official CBA announcements regarding player availability, injury status, and any schedule modifications through the settlement window. Recent roster moves, coaching changes, or late withdrawals could materially shift the underlying matchup dynamics. The absence of meaningful YES-side liquidity on the order book suggests limited conviction in a Shanxi upset, though the extended settlement period creates opportunity for late information to alter market pricing should circumstances change before the scheduled fixture date.
This market settles from the official outcome published at https://www.flashscore.com/basketball/china/cba. 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 "Shanxi Loongs vs. Zhejiang Lions" 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.
$118K in lifetime turnover and $255K of resting liquidity puts this market in the top 30% by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $118K 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.
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.

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.
