How Do Polymarket Markets Work For Thunder vs. Spurs Game 4
Polymarket works in a different way from traditional sports betting sites. Instead of betting fixed odds, users buy and sell shares connected to outcomes in sports, politics, entertainment, and other real-world events. Each prediction market gives users access to “Yes” and “No” contracts.
Prices typically range from 1¢ to $1 and reflect the market’s implied probability of an outcome happening. For example, if a Yes share on the Thunder to win trades at 47¢, the market is pricing Oklahoma City around a 47% chance to win. Winning shares settle at $1 after the result is official, while losing shares settle at $0.

A major advantage of prediction markets is that users do not have to hold a position until the final result settles. Shares can be bought or sold before the game ends, giving traders more flexibility if injury news breaks, lineups change, or live momentum shifts during Thunder vs. Spurs Game 4. That allows users to lock in profit, limit downside, or adjust their exposure before the market closes.
