Market context

Polymarket is pricing the Cavaliers side at 37% YES, with USDC locked on Polygon and the contract settling through conditional tokens once the final score is official. The underlying event is the NBA playoff game between Cleveland and Detroit scheduled for 17 May at 12:00 AM ET, and the market resolves on the winner after overtime. At that price, the crowd is assigning Detroit a clear edge rather than treating this as a coin flip.

That reading sits below several published pre-game lines. CBS Sports reported Detroit as a 4.5-point favourite with a 211.5 total for Game 5, while other previews had Cleveland around -172 to -180 on the moneyline and a 209.5 total in Cleveland for a different game in the series. Those mixed signals show how much the series has swung, but the market’s 37% on Cleveland is still well below a typical near-even playoff game, implying the crowd is leaning on home-court, recent form, or a late-series adjustment rather than the headline moneyline alone.

Traders should watch for any official injury updates, starting line-ups, and confirmation that tip-off remains on schedule, because this market stays open if the game is postponed and only resolves when the game is completed. Late breaking availability for primary creators such as Donovan Mitchell or Cade Cunningham, plus any change in venue or start time, would be the main catalysts for repricing. With the settlement tied to the final result, any overtime game also counts in full, so live uncertainty is limited to whether the fixture goes ahead as planned.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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.

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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in 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.
