Market outcomes
| Chongqing Tonglianglong FC | 49% YES | 51% NO |
| Draw | 49% YES | 51% NO |
| Yunnan Yukun FC | 49% YES | 51% NO |
Chongqing Tonglianglong FC will host Yunnan Yukun FC in a Chinese Super League fixture on 20 May 2026. The halftime result market is pricing a 49% probability for a Chongqing home win at the interval, with settlement occurring at 12:00 UTC on match day. The current odds reflect Polymarket's order book depth and recent trading activity, where liquidity has formed around this midpoint across the three halftime outcomes.
Chongqing's recent domestic form and home record provide the baseline for interpreting this probability. Teams in the Chinese Super League typically score 0.8–1.2 goals per 45 minutes in competitive fixtures; halftime results are heavily weighted towards either a home advantage or defensive solidity from the visiting side. Yunnan's away record and squad composition relative to Chongqing's roster strength will determine whether the current 49% reflects fair value or underprices either team's likelihood of leading at the interval.
Traders should monitor team news releases and official lineups in the 48 hours before kick-off, particularly injury confirmations or tactical shifts. Weather conditions in Chongqing on match day—temperature and pitch state—can influence early-game tempo and scoring likelihood. Recent fixture congestion in the Super League calendar may affect squad rotation decisions. The settlement window closes at 12:00 UTC, giving traders a narrow window to react to halftime confirmation from the match broadcast.
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 "Chongqing Tonglianglong FC vs. Yunnan Yukun FC - Halftime Result" 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 $39 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.
