2025 NASCAR Cup Series Championship Odds: Updated betting lines for Phoenix

The finale of the 2025 NASCAR Cup Series season is upon us. A new champion will be crowned at Phoenix Raceway, as the Championship 4 descend to the desert.

William Byron won his way into the event at Martinsville, holding off Ryan Blaney in a heated battle. Kyle Larson bested Christopher Bell on points, sending a second Hendrick Motorsports wheelman to Phoenix. They’ll join two Joe Gibbs Racing drivers in their chase for a title, as Denny Hamlin and Chase Briscoe entered this past weekend with their spots in the finale already secured.

With a champion ready to be crowned, BetMGM Sportsbook has unveiled their updated championship odds heading into the final race. Here’s how the title picture looks as NASCAR’s best prepare for the last race of the season, where only Larson is the only past champion. Everyone else is searching for No. 1.

Denny Hamlin (+210)

Denny Hamlin enters Phoenix as the prohibitive favorite. He’s never won a Cup Series title in his illustrious NASCAR career, but he’s among the best to ever grace the sport behind the wheel. His 60 wins are evidence of that, and a championship is the main from his mantle.

His last win at Phoenix came back in Nov. 2019. Earlier this season, he finished as the runner-up in the desert to his Joe Gibbs Racing teammate in Christopher Bell. This is the fifth appearance in the Championship 4, we’ll see if it’s the time he finally gets over the hump.

Kyle Larson (+240)

Kyle Larson is back in the Championship 4 for the third time. He won the championship back in his first appearance, which came in 2021. This hasn’t been his most dominant season, but his talent has been on full display throughout the playoffs, as he’s the lone driver in the Championship 4 who didn’t win his way in during the Round of 8.

Phoenix has always been one of his best tracks. His last win in the desert came in 2021, when he clinched his first career Cup Series title. It remains his lone win at the track, but he finished third at the venue earlier this season, right behind Denny Hamlin. We’ll see if he can win title No. 2 this weekend.

William Byron (+260)

William Byron had to win his way into the Championship 4, and he’s back in Phoenix to race for the title for the third season in a row. After a dominant performance at Martinsville, perhaps this is the season he’s finally able to get over the hump, as he won’t have to deal with Team Penske at Phoenix this time around.

He does have a win at the track, but that came back in March of 2023. He finished sixth at the venue earlier this season, and he always has plenty of speed. Byron seems to be on a championship trajectory, but he has to finish the job. Maybe this is the year he gets it done.

Chase Briscoe (+375)

Chase Briscoe won his way into the Championship 4 at Talladega. That’s not to say he doesn’t deserve to be here. He’s been one of the more consistent wheelmen in the field since joining Joe Gibbs Racing, especially over the course of the second half of the season.

The No. 19 Toyota team has found a way to compete seemingly each and every week. Earlier this season though, Briscoe had trouble in the desert, as he finished P35 after starting P30. He does have a win at the track though, one that came back in March of 2022 when he was racing for Stewart-Haas Racing.
