Market context
The Chinese Basketball Association regular season fixture between Shenzhen Leopards and Zhejiang Lions takes place on 23 May at 7:35 AM ET. The current 0% implied probability on this market reflects either extreme confidence in one outcome or, more likely, minimal liquidity and trading activity on this particular matchup across Western prediction platforms. CBA games rarely attract significant volume on Polymarket or Kalshi compared to major US sports, creating wide bid-ask spreads and sparse order books that can distort apparent consensus.
Historical context matters considerably here. Shenzhen and Zhejiang occupy different tiers of CBA competitiveness; Zhejiang Lions have consistently performed stronger in recent seasons, finishing higher in league standings and advancing further in playoffs. When Eastern Asian basketball matches appear on Western platforms, the probability distribution often reflects Western traders' unfamiliarity with team rosters and form rather than genuine analytical disagreement. Betfair and Smarkets, which maintain stronger Asian sports coverage through regional liquidity pools, typically show more balanced odds on CBA fixtures than Polymarket's decimal-odds format, which can amplify the appearance of extreme probabilities when actual trading volume is low.
Traders should monitor CBA injury reports and roster confirmations in the week preceding 23 May, as late-notice absences significantly shift matchup dynamics. The settlement window closing 30 May allows for postponement contingencies, though cancellation without rescheduling would trigger the 50-50 resolution clause. Comparing this market's liquidity across platforms reveals how fragmented Western prediction markets remain for non-English-language sports; KYC requirements on Kalshi versus Polymarket's lighter verification may also influence which traders can access each book's CBA pricing.
Methodology
We read Shenzhen Leopards vs. Zhejiang Lions from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.

- 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.
