Each venue settles a team's market Yes only if that team wins, and the dates below come from the venues' own listings.
- Kalshi. A team's market settles Yes if that team wins the 2027 pro basketball finals, and the market closes once a champion is declared. Kalshi expects to settle on 31 July 2027.
- Polymarket. A team's market settles Yes if that team wins the 2026-27 NBA championship, and settles No as soon as the team can no longer win, for example when it is knocked out of the playoffs. The market is scheduled to close on 30 June 2027, and if no champion is declared by then Polymarket resolves it to Other, not to a listed team.
- The chances. A Yes share pays $1 if the team wins, so a price of 14 cents is a 14% chance. For Kalshi we use the midpoint of the best bid and ask when they are within 10 cents of each other, and the last trade when they are not. For Polymarket we use the price it publishes for Yes.
- The volume. Kalshi counts contracts and Polymarket counts US dollars, so the two totals cannot be compared directly.

These are the questions people ask about Kalshi and Polymarket odds on the 2027 NBA champion.

Kalshi rates the San Antonio Spurs first, at 21.5%, and Polymarket rates the San Antonio Spurs first, at 22.5%, as read on 12 Nov 2026. That is the price of a Yes share, in cents, turned into a percentage, and it moves with every trade.
What do the 2027 NBA Finals odds on this page mean?
Each percentage is the price of a Yes share in one team's market. A share pays $1 if the team wins, so a price of 14 cents means the market gives that team about a 14% chance. It is what traders are paying, not a promise: a team at 14% still loses about 86 times in 100 if the prices are set well.
How do Kalshi and Polymarket differ for this market?
Both ask which team wins the 2027 NBA Finals, and both pay $1 for a winning share. Kalshi, a US-regulated exchange, counts trading in contracts (64.5M contracts so far), while Polymarket counts US dollars ($38.3M so far), so the totals cannot be compared directly.

Golden State Warriors: Kalshi gives 3.5% and Polymarket gives 2.1%, a gap of 1.5 points.
Why do the chances not add up to exactly 100%?
Each team's price is set by its own trading, so the prices need not add up to exactly 100%. On this read Kalshi's chances add up to 106% and Polymarket's to 103.7%. Kalshi's total runs above 100% partly because a team quoted between 0 and 1 cent shows as 0.5%.
