Knicks vs. Spurs Game 4: Polymarket Market Analysis (8:30 p.m. ET, ABC, Madison Square Garden)
New York reached the NBA Finals on a dominant run: beating Atlanta 4-2, sweeping Philadelphia, and then Cleveland in the Eastern Conference Finals. They opened the Finals by winning both games in San Antonio, 105-95 and 105-104, before the Spurs took Game 3 at MSG 115-111 to avoid falling into a 3-0 hole. The Knicks lead 2-1 but lost their first home game of the series, which makes tonight's Game 4 the pivotal matchup. With a win, New York heads back to San Antonio up 3-1. With a loss, the Finals are even with the series fully reset.
Current Polymarket win probability for Knicks vs. Spurs Game 4:
- New York Knicks: 54% — approximately $0.54 per share
- San Antonio Spurs: 47% — approximately $0.47 per share
Here's how to put your $50 bonus to work on the Knicks tonight. A $50 trade on New York at $0.54 buys around 91 shares — returning $91.31 for a $41.31 profit, if the Knicks protect home court and take a 3-1 series lead. If you think the Spurs even the series after their Game 3 showing, $50 on San Antonio at $0.47 buys roughly 104 shares for a $54.69 profit. Since Polymarket is an exchange, you can sell your Knicks shares mid-game. If New York jumps out to a double-digit lead and their price climbs to $0.80, you can lock in the gain before the final buzzer.

Knicks NBA Championship Futures on Polymarket
Beyond tonight's game, Polymarket's NBA Championship market is where the Knicks' Finals run gets interesting. With New York up 2-1, their title price reflects a team two wins from its first championship since 1973, and that number will move sharply tonight.
A Knicks win in Game 4 pushes them to 3-1 and would send their championship contract well above its current price (62.5%), likely to the 80% range as a 3-1 Finals lead is historically close to insurmountable. A Spurs win evens the series at 2-2 and resets New York's title price back towards a coin flip. That volatility is the opportunity: buying Knicks championship futures before tonight's tip-off captures a better price than waiting for a potential 3-1 lead to reprice the market upward.
For a Knicks fan who believes this is finally the year, the futures market lets you hold a position across the rest of the series rather than game by game. Your $50 bonus from the Polymarket promo code ACTION is enough to take both a Game 4 position and a NBA championship futures stake from a single deposit.
