Market context
Shenzhen Leopards face Zhejiang Lions in a CBA playoff game on 21 May, with the market resolving on the final score after any overtime. The current 100% YES pricing leaves no practical room for a data-driven disagreement unless there is a late schedule change, since the event is already listed across live-score and betting feeds as an active matchup. For a programmatic trader, that makes the primary task not prediction but event integrity: confirm tip-off status, verify the teams are still the same fixture, and monitor whether any postponement pushes the settlement clock out towards the market’s 28 May window.
Recent results frame why the line has anchored so hard. Zhejiang won Game 2 by 92-85 and moved 2-0 up in the semi-final, with Barry Brown scoring 30 points; Shenzhen now need a response at home, but the series state means the Lions remain the clear form side. Comparable playoff cases in CBA markets tend to price heavily towards the leading team once a series gets to 2-0, especially when the last result was a comfortable cover of the implied gap. The earlier meeting also matters: Shenzhen beat Zhejiang 109-94 in April, so the matchup is not one-way on historical terms, but the immediate series evidence is stronger than the season snapshot.
The main catalysts to watch are simple but time-sensitive: any official CBA announcement on venue, start time, or postponement; team injury or rotation news; and whether the game remains on the published schedule in live data sources such as SofaScore or Flashscore. For copy-trading or conditional-order systems, the useful trigger is not score modelling but status drift: if the fixture is confirmed as on, the market should stay settled to the basketball result; if it slips, the open period persists until the rescheduled game is played. That makes pre-tip status checks more valuable than pre-match statistical edges.

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.
