How To Understand Polymarket Markets to Trade on Cavs vs. Knicks
Polymarket operates differently from traditional sports betting sites. Instead of fixed-odds, users buy and sell shares tied to predicting outcomes in sports, politics, entertainment, and other real-world events. Each live prediction market is regulated and gives users access to "Yes" and "No" contracts.
Prices range from 1¢ to $1 and represent the implied probability of an outcome occurring. For example, if a Yes share for the Knicks to win trades at 69¢, the market is estimating roughly a 72% chance of that result occurring. Winning outcomes for Cavs vs. Knicks settle at $1 after resolution, while losing shares expire at $0.

|---|---|
| Cavs vs. Knicks | Cavs 32% / Knicks 68% |

One major difference from traditional betting is flexibility before settlement. Traders are not locked into positions until the game ends. You can buy out at any time. If market sentiment changes during the day, after breaking news, or a player gets injured, users can sell shares to lock in gains today or reduce exposure before the final result becomes official.
Polymarket has also recently expanded its NBA offerings during the playoffs, adding player-focused contracts tied to scoring, rebounds, assists, and other stat-based outcomes. These prediction markets generate some of the platform’s highest volume during the 2026 NBA Postseason games.
