Market context
The Chinese Basketball Association (CBA) will host a match between the Shenzhen Leopards and Zhejiang Lions on 23 May at 7:35 AM Eastern Time. In a prediction market, traders purchase YES or NO shares based on their conviction about the outcome. A YES share pays out if the Leopards win; a NO share pays out if the Lions prevail. The settlement window closes on 30 May, allowing a week for the game to be played and verified. Should the fixture be postponed, the market remains open until completion. A complete cancellation with no rescheduled date would trigger a 50-50 split of the pot between both share types.
The 0% implied probability for a Leopards victory reflects either substantial confidence in a Lions win or minimal trading activity in this particular market. Historical CBA matchups between these franchises provide context: recent seasons have seen competitive performances from both clubs, though the Lions have generally held stronger playoff positioning. The current probability reading should be interpreted cautiously given the low liquidity typical of niche sports markets; sparse trading can produce extreme probabilities that don't reflect genuine predictive consensus.
Traders monitoring this market should track roster availability and injury reports from both teams in the fortnight before the fixture. The CBA regular season schedule occasionally experiences disruptions due to administrative changes or venue conflicts, making postponement risk material. Recent CBA communications regarding May fixtures should be consulted; official league announcements typically confirm scheduling details 7–10 days in advance. Team form in the weeks preceding 23 May—particularly win-loss records and head-to-head records—will inform whether the current probability reflects genuine competitive imbalance or simply thin order books.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
FAQ

- On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- Is this market available outside the US?
- PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
