Beijing Ducks vs. Shanghai Sharks

Platform comparison

Market context

Beijing and Shanghai meet in the CBA playoffs, with the result to be settled by the final score, including any overtime. The current 0% YES crowd price can be read against the series context: the Sharks were the stronger regular-season side, but the Ducks have already shown they can draw level in the matchup after splitting the opening games, including a 116-99 Beijing win reported by Chinese-language coverage and courtside video from the last round of results. That makes the market unusually sensitive to lineup news and game-day availability rather than broad team reputation alone.

For compliance context, a market like this sits in a grey zone for some users rather than a pure sports-betting analogue. German GlüStV rules can affect access where participation is treated as gambling, while the US CFTC’s jurisdiction is relevant if a platform is viewed as offering event contracts to US persons. “No-KYC up to $1,500” means a user may be able to trade up to that cumulative level without identity verification on the platform, but it does not remove local legal or tax obligations. Traders should watch official CBA scheduling notices, any injury or rest updates, and whether the game starts on time or is moved, because postponement keeps the market open until completion; cancellation without a make-up would settle 50-50.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

Is this market available outside the US?
