Market context
The Cavaliers and Knicks have already played Game 1 of the Eastern Conference finals, and New York won 115-104 after overturning a 22-point deficit in the fourth quarter and overtime. ESPN’s game page shows Cleveland as the listed team for the fixture and the market’s current 0% YES pricing implies the contract is being treated as effectively settled on the completed result rather than a live pre-tipoff contest. On a cross-platform basis, that leaves a clear gap between sportsbook-style framing, which would have made New York a live underdog before tip, and the prediction market, where the implied probability has collapsed to zero after the final whistle. The main comparison point is not a routine regular-season meeting but a playoff game decided in overtime, where late scoring swings can flip an entire contract.
For traders, the key catalyst is the final status of the game itself: it has already been completed, so any attention now centres on settlement timing rather than on-team news. ESPN’s report on the comeback noted Jalen Brunson’s role in the 44-11 closing run, while Donovan Mitchell’s post-game comments on Cleveland’s side suggest no delayed injury issue is driving uncertainty around the result. The relevant dependency is the market rule on postponements and cancellations, but neither appears applicable here because a final score including overtime has been posted. In practice, that means analyst consensus, sportsbook logic and the market outcome should all point the same way, with no meaningful disagreement left on the contract.
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.
FAQ
- 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.
- What does it cost to trade on PolyGram?
- Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
