A crucial road victory by the San Antonio Spurs in Game 3 of the Pro Basketball Finals on Monday, June 8, 2026, has significantly altered the outlook in a key prediction market. In the session following the Spurs' 115-111 win over the New York Knicks, contracts for a San Antonio championship (KXNBA-26-SAS) saw their implied probability spike 15.0 percentage points, rising to 38% from a post-Game 2 low of 23%. The move signals that traders are pricing in a much more competitive series after the Spurs avoided a historically insurmountable 0-3 deficit.
The repricing reflects a direct transfer of probability from the Knicks, whose odds of winning the series fell by 14.0 percentage points to 63%. The shift occurred on heavy volume, with over 1.1 million contracts traded on the rising "San Antonio" outcome, suggesting strong conviction behind the move. Despite the rally, the market still implies the Knicks are the favorites to win their first title since 1973.

What's Driving the Shift
The significant repricing away from a near-certain Knicks victory appears to be driven by San Antonio's performance in a must-win Game 3 at Madison Square Garden.
Avoiding a 0-3 Deficit: The primary driver was the Spurs' ability to secure a win on the road, cutting the Knicks' series lead to 2-1. No team in NBA history has ever recovered from a 0-3 deficit to win a playoff series. By avoiding this scenario, the Spurs have kept their championship hopes viable and guaranteed the series will continue for at least two more games.
Knicks' Momentum Halted: The loss snapped an impressive 13-game Knicks winning streak, which was their first postseason defeat in 46 days. The Spurs' ability to win in a hostile New York environment demonstrates a resilience the market had previously priced out after the Knicks' two opening victories in San Antonio.
Wembanyama’s Star Performance: Spurs star Victor Wembanyama was instrumental in the victory, scoring 32 points. His dominant play, after a crucial late-game turnover in Game 2, reaffirmed his ability to carry the team on the league's biggest stage, likely boosting trader confidence in San Antonio's ability to compete.
Market Context
The 2026 Finals market has been volatile. The Spurs entered the series as favorites, but odds shifted dramatically after they lost the first two games at home. Following their 105-104 loss in Game 2, the Knicks became heavy betting-line favorites at -490, implying a probability of roughly 83%.
The subsequent 15.0 percentage-point rally for the Spurs represents a significant correction from that low point. While still positioned as underdogs at 38%, their current implied odds are far stronger than for any team that has ever faced a 0-2 deficit after losing the first two games at home.
What to Watch
All eyes will be on Game 4, scheduled for Wednesday, June 10, in New York. The outcome is pivotal: a Knicks victory would give them a commanding 3-1 series lead and likely cause their odds to surge back toward post-Game 2 levels. A second consecutive Spurs win, however, would tie the series 2-2, turning it into a best-of-three and likely pushing the market odds closer to a 50/50 split. The settlement source for the market is the official NBA championship result.
