Prices are implied probability derived from each venue's live quote (exchange price or American odds with vig). Bold, underlined marks the single highest-payout price across every venue for that entrant. Edge = sportsbook-consensus probability minus exchange probability, in percentage points — a positive edge means sportsbooks price that outcome higher than the exchange does; a gap of 1+ point is stamped. Stale flags any quote observed more than 48 hours ago.

Frequently Asked Questions

What is the odds gap between exchanges and sportsbooks on the NBA Championship?
Our data shows the widest current gap is on Oklahoma City Thunder: Polymarket prices it at 19.5%, while sportsbooks imply 28.9% on average — a +9.4pt difference on the identical outcome.
Where can I get the best price on the NBA Championship?
It depends on the entrant — the table above marks the single best (highest-implied-payout) price per entrant across every tracked venue. No one venue wins across the board: Polymarket and BetMGM, BetRivers, FanDuel each lead on different entrants.
How many venues does Odds Reference track for the NBA Championship?
4 venues currently: Polymarket as prediction-market exchange, and BetMGM, BetRivers, FanDuel as sportsbooks, across 30 entrants with a live quote from both venue types.
Why do exchange and sportsbook prices differ for the NBA Championship?
Prediction-market exchanges like Polymarket set prices through open order-book trading, while sportsbooks price futures using their own risk models and hold a built-in vig. The two rarely land on an identical number — our data shows gaps of several points are common, and occasionally exceed 9 points on a single entrant, as with Oklahoma City Thunder above.
