For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution.

Market outcomes
| Zhejiang Zhiye FC | 39% YES | 62% NO |
| Draw (Zhejiang Zhiye FC vs. Shandong Taishan FC) | 31% YES | 69% NO |
| Shandong Taishan FC | 35% YES | 65% NO |
Zhejiang Zhiye and Shandong Taishan will meet in the Chinese Super League on Wednesday, 20 May 2026. The current order book on Polymarket prices a YES outcome (interpreted as a Zhejiang victory or draw, depending on market definition) at 37%, reflecting modest confidence in that result relative to a Shandong win. This probability has formed through recent trading activity and reflects the aggregate view of market participants weighing both teams' current form and fixture context.
Shandong Taishan have historically been among China's strongest sides, winning the Super League title in 2021 and consistently competing for honours. Zhejiang Zhiye, by contrast, have occupied mid-table positions in recent seasons. Head-to-head records and seasonal performance gaps typically favour Shandong, which contextualises why the market is pricing a YES outcome below 40%. However, Chinese Super League results remain volatile; home advantage, squad rotation, and mid-season form shifts can substantially alter expected outcomes.
Key variables for traders to monitor include team news on injuries or suspensions, which the Chinese Football Association typically announces in the week preceding fixtures. Shandong's fixture congestion in May—including potential cup commitments—may affect squad availability. Recent league standings and points differentials between the sides will sharpen probability estimates as the settlement window approaches. Weather conditions in Zhejiang on match day and any last-minute tactical announcements from either manager could shift the order book in the final hours before kick-off.
This market settles from the official outcome published at https://www.csl-china.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 "Zhejiang Zhiye FC vs. Shandong Taishan FC" 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.
$0 in lifetime turnover and $2K 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.

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.
