In a significant repricing on Monday, May 11, 2026, the prediction market for the NHL second-round playoff series between the Vegas Golden Knights and the Anaheim Ducks shifted sharply. The Golden Knights' implied probability of winning the series fell 15.0 percentage points to 60.0%, while the Ducks' chances climbed 14.0 percentage points to 41.0%. This market recalibration directly followed Anaheim's 4-3 victory in Game 4 on Sunday, which tied the best-of-seven series 2-2, and coincides with a key injury to Golden Knights captain Mark Stone.
Distribution Analysis
The probability shift was concentrated entirely between the two competing outcomes, reflecting the market's reassessment of what is now effectively a best-of-three series. Notably, the volume on the rising Ducks contract was more than double that of the declining Golden Knights contract, suggesting strong conviction behind the move toward Anaheim.
| Outcome | Current Prob | Change | Volume |
|---|---|---|---|
| Vegas Golden Knights | 60% | -15.0pp | 16,919 |
| Anaheim Ducks | 41% | +14.0pp | 42,503 |
Net: Probability shifted decisively toward the Anaheim Ducks on high volume, narrowing the implied odds in what is now a best-of-three series.
What's Driving the Shift
Several on-ice factors appear to be driving the market's repricing, moving the series from a strong Vegas lean to a more competitive outlook.
Series Tied 2-2: The primary catalyst was the Anaheim Ducks' 4-3 victory over the Golden Knights in Game 4 on Sunday, May 10, at Honda Center [4], [5]. The win evened the series at two games apiece, erasing Vegas's series lead and forcing a pivotal Game 5. The Ducks responded to a 6-2 blowout loss in Game 3 with a strong performance to tie the series [4].
Key Injury for Vegas: The Golden Knights played Game 4 without their captain, Mark Stone, who suffered an undisclosed injury in Game 3 [4], [5]. Stone's absence from the lineup removes a key player for Vegas, and his uncertain status for the remainder of the series has likely been priced in by traders as a significant blow to the team's chances.
Shifting On-Ice Momentum: Anaheim's power play, which had been 0-for-11 to start the series, came to life in Game 4, scoring two crucial goals [6]. This breakthrough against a Vegas penalty kill that had been dominant suggests the Ducks are adapting and finding solutions, boosting confidence in their ability to compete for the remainder of the series. Beckett Sennecke scored the Ducks' first power-play goal of the series, ending a streak of 21 consecutive penalty kills for Vegas [6].
Market Context
Despite the significant shift, the Golden Knights remain the favorites at 60%. This is likely due to their holding home-ice advantage for the remainder of the series. Two of the potential three remaining games, including the critical Game 5, are scheduled to be played at T-Mobile Arena in Las Vegas [1], [4].
The market pricing implies that while the series is now seen as much closer, home ice provides Vegas with a distinct, though not insurmountable, advantage. The series opened with Vegas winning Game 1 by a score of 3-1 before Anaheim evened the series in Game 2 [2]. With the series now tied, the market has moved from pricing a likely Vegas victory to pricing a highly competitive contest where the home team has a moderate edge.
What to Watch
All eyes will be on Game 5, which is scheduled for Tuesday, May 12, in Las Vegas [5]. The outcome of this game will be a decisive indicator and will almost certainly trigger another significant price movement. Traders will also be closely monitoring news regarding the injury status of Mark Stone, as his potential return could shift probabilities back in favor of the Golden Knights. The market is scheduled to close on June 2, 2026, with settlement based on official results from sources including ESPN and the NHL [3].
