Zhejiang Lions vs. Shanghai Sharks

Platform comparison

Market context

The Chinese Basketball Association matchup between Zhejiang Lions and Shanghai Sharks is scheduled for 31 May at 7:35 AM ET. The current crowd-implied probability of 0% YES reflects either extreme confidence in Shanghai's prospects or minimal trading activity on this particular contract. Settlement occurs by 7 June 2026, with the result determined by final score including overtime. Postponement triggers an extension; cancellation without rescheduling resolves the market 50-50.

Zhejiang and Shanghai represent two mid-tier CBA franchises with inconsistent recent form. Historical matchups between these clubs show competitive balance, though Shanghai has held a slight edge in head-to-head records over the past three seasons. The 0% probability reading appears disconnected from typical sportsbook spreads for CBA fixtures, which rarely show such extreme confidence in either side. This divergence suggests either sparse liquidity on this contract or a data-reporting lag rather than genuine consensus dismissal of Zhejiang's chances.

Traders should monitor roster availability in the week preceding the fixture, particularly injury status for key contributors on both squads. CBA scheduling occasionally shifts due to venue conflicts or administrative changes, so confirmation of the 31 May date remains essential. Recent CBA season updates and team announcements typically appear via official league channels and Chinese sports outlets; any late-notice postponement would extend this market's settlement window. The current probability warrants scrutiny against available sportsbook lines and recent team performance metrics before committing capital.

Methodology

We track Zhejiang Lions vs. Shanghai Sharks on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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

Is this market available outside the US?

Best Prediction Markets UK 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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
