How to Use NBA Prediction Markets

Understanding how to use NBA prediction markets is not difficult, as the trading process is very straightforward. With prediction market platforms, the unit of commerce is an event contract, as users are buying shares (yes/no) for either side of an event outcome. Each contract has a total value of $1, and each side is priced $0.01-$0.99 based on the implied market probability (%). Traders can buy and sell contracts for either side of the market, and once it resolves, they will receive the full value of each of the (correct) contracts that they own.

For example, basketball fans can trade on the winner of the 2027 NBA Finals. If a user wants to trade on the San Antonio Spurs, they can buy (yes) contracts for $0.24 each. If the Spurs end up winning the championship, that trader will return a profit of $0.76 per share.

Here’s that NBA event contracts equation: Full Contract Price ($1) – San Antonio Spurs Price ($0.24) = $0.76 Profit.

NBA Champion Prediction Markets

Will Oklahoma City Thunder win the 2027 NBA Finals?
Yes 22% · No 79%
View full market & trade on Polymarket

Trading on the 2027 NBA Champion is the most popular futures market for basketball prediction markets, with already tens of millions of dollars in trading volume on platforms like Kalshi and Polymarket. The San Antonio Spurs are hovering as a slight favorite in the prediction markets for the 2027 NBA championship, after falling to the Knicks in the 2026 Finals. There is extremely high market liquidity for trading on the 2027 NBA Finals, allowing users to execute set-price (limit) trades and also sell positions early if an opportunity to profit arises.

NBA MVP Prediction Markets

Trading on the MVP of the NBA season is the most popular market for individual player awards, as the MVP race is always one of the biggest storylines in any NBA season. Based on the markets, Shai Gilgeous-Alexander is the pre-season favorite to capture the Most Valuable Player trophy, which would be his second consecutive MVP award. In the 2024-25 season, SGA won league MVP while his Oklahoma City Thunder went on to win the NBA Finals. The young superstar will look to lock up another clean sweep this season after his team fell to the San Antonio Spurs in the 2026 Western Conference Finals.

NBA Rookie of the Year Prediction Markets

Will Cameron Boozer win the 2026-27 NBA Rookie of the Year?
Yes 23% · No 78%

NBA Defensive Player of the Year Prediction Markets

Defensive Player of the Year is another popular individual award for the NBA season, and prediction markets provide a trading platform for users to buy and sell contracts on all the action.
