Mammoth vs. Golden Knights Game 5 Prediction: Vegas Looks to Close Out Series at Home

After one of the most wild Game 4s of the 2026 Stanley Cup Playoffs, the Utah Mammoth and Vegas Golden Knights are headed back to Las Vegas for Game 5 on Wednesday night at T-Mobile Arena. The series is tied 2-2 after Vegas overcame a 4-3 third period deficit to win in overtime on Monday, with Shea Theodore scoring the winner with just 51.5 seconds remaining in the extra period. Game 5 takes place with Vegas re-establishing home-ice advantage and the Mammoth knowing they had a chance to take a 3-1 series lead and let it slip through their fingers.

Utah finished the regular season 45-35-6 with 96 points, coming in as a slight underdog entering this series against a Vegas team (41-28-17) that did not have the most convincing regular season record but has one of the most dangerous home environments in the NHL. T-Mobile Arena has been a fortress for the Golden Knights, and in the playoffs, the crowd noise and intensity level there is among the highest in the league. Utah won Games 2 and 3 on the road in Las Vegas, so the Mammoth have already shown they can handle that environment. But Game 5 pressure is a different kind of test.

Vegas Installs as Significant Favorites at T-Mobile

The Golden Knights opened as -166 moneyline favorites for Game 5, with Utah sitting at +140. The over/under is set at 5.5. Vegas won both home games in this series, including a 4-2 opening win in Game 1, and they have been the stronger team on their own ice across the four games played so far. Jack Eichel has been the best player in the series for Vegas, finishing Game 4 with three assists and five total assists through the first four games. He logged 29 minutes in Game 4 overtime, which tells you everything about how much the Knights lean on him when the game is on the line.

Eichel vs. the Mammoth Defense: Who Controls the Pace?

The statistical picture in this series is remarkably even. Both teams have scored 13 goals through four games, and the hit total is almost identical: Utah leads 168-167. Utah goaltender Karel Vejmelka holds a slight edge over Vegas netminder Carter Hart in save percentage, .899 to .886. Hart had a difficult Game 4, allowing four goals, but made 27 saves and held on when it mattered in overtime. Vejmelka, who has been reliable all series, gave up five but faced 36 shots and was let down defensively on several plays.

The Mammoth’s identity in this series has been their ability to come back. They rallied from 3-0 down to lead 4-3 in Game 4 before Vegas equalized with 9:35 left in the third. Clayton Keller continues to be Utah’s engine, with a goal and six shots on goal in Game 4. He and Dylan Guenther form one of the most dangerous forward duos in the Western Conference, and Guenther’s 39 goals and 34 assists during the regular season are numbers that demand respect from any defense. Nick Schmaltz has been equally impactful, posting two points in Game 4 and winning faceoffs at a high rate against one of the better centers in the game in Eichel.

Mikhail Sergachev has been Utah’s most impactful defenseman, posting three assists in Game 4 alone. His ability to quarterback the power play and play heavy minutes makes him a key figure in this series. MacKenzie Weegar has also been physical and effective on the back end, leading Utah with nine hits in Game 4 and adding defensive reliability behind Sergachev. Utah’s defensive core, which also includes John Marino and Nate Schmidt, has been asked to handle a difficult assignment against a Knights offense that features multiple game-breaking players.

For Vegas, Brett Howden has been an unlikely hero. He scored two goals in Game 4, including a shorthanded tally and the equalizer in the third period. Howden now leads the Golden Knights in this series with two goals and three points. Mitch Marner, acquired in the offseason, has been a consistent presence with four assists in the series, even though his offensive production at even strength has been inconsistent. Mark Stone’s playoff experience and leadership remain crucial as a veteran voice on a team that has deep championship DNA.

The injuries are minimal on both sides, though they are notable. William Karlsson is out for Vegas with a lower-body injury, which removes a key center from their lineup. Barrett Hayton is out for Utah with an upper-body injury. Given how close the series has been, those absences carry weight. Karlsson was a 30-goal scorer for most of his career and would have provided additional depth behind Eichel and Howden. Utah will miss Hayton’s two-way presence.

Utah has won two of three meetings in Las Vegas this season, including a 3-2 Game 2 win on a Logan Cooley third-period goal. That track record matters. The Mammoth are not intimidated by T-Mobile Arena, and their last 10 games regular season record was 5-4-1, slightly better than Vegas at 7-2-1 in the same stretch. Utah goes 43-11-1 when scoring three or more goals, a stat that suggests they are a different team when they can get their offense rolling.

Prediction and Best Bet

Vegas is the right side here. They have home ice, a demonstrably better record at T-Mobile Arena, and Eichel playing at an elite level. The Golden Knights also benefit from the psychological edge of having stolen Game 4 in overtime after looking like they might lose the series lead. Utah will come out motivated after blowing a late lead, but playing in a hostile environment the game after a gut-punch overtime loss is historically difficult.

Utah’s resilience makes them capable of winning this game, and the series will go to at least six games no matter what. But Game 5 at home for Vegas, with Eichel and Theodore performing well, is the right spot to back the Golden Knights. The -166 moneyline is steep but reflects the reality of this series dynamic.

• Prediction: Vegas Golden Knights 4, Utah Mammoth 3
• Best Bet: Vegas Golden Knights moneyline (-166)

Backing Vegas at home in a pivotal Game 5 is sound reasoning given their track record in these spots. T-Mobile Arena has been a decisive factor in the series, and after the emotional win in Game 4 overtime, the Golden Knights will have the crowd behind them from the opening puck drop. Utah is a capable team and could pull off the upset, but the edge in this game belongs to Vegas.
