NASCAR Cup Series at Las Vegas.

The NASCAR Cup Series circuit takes on Sin City today (March 15) for the running of the Pennzoil 400 at the Las Vegas Motor Speedway. The race around the 1.5-mile track is scheduled for 267 laps and 400 miles.

Entering today’s race, Kyle Larson aims to pull off the weekend sweep after winning yesterday’s O’Reilly Auto Parts Series race. Meanwhile, a group of Toyotas will look to upset the two-time and defending Cup Series champion.

Ahead of the fifth race of the 2026 Cup Series season, this is a look at the odds.

Kyle Larson enters Sunday as the favorite to win

After a fifth-place qualifying effort and a win in the O’Reilly Auto Parts Series race, it’s no surprise Larson is the odds-on favorite to win on Sunday.

The driver of the No. 5 enters today’s race at +350 to win, via DraftKings Sportsbooks. The Hendrick Motorsports driver is a three-time Las Vegas winner, with his latest victory coming in March 2024.

In his last six races at the track, Larson has totaled three wins, two runner-up finishes, and has placed no worse than 11th in all of them. Larson is aiming for his first Cup-O’Reilly weekend sweep since Bristol in April of last year.

Toyota drivers seek to upset Larson at Las Vegas

Kyle Larson is not the only driver expected to have a fast race car in today’s race.

Christopher Bell will lead the field to green after earning the pole in Saturday’s qualifying. The driver of the No. 20 enters Sunday with the second-best odds to win at +500.

In the last five Las Vegas races, Bell has posted three top-five finishes, including runner-up efforts in October 2023 and October 2024. However, the Oklahoma native has failed to win in Sin City.

Making up a Joe Gibbs Racing 1-2-3 starting grid, Denny Hamlin starts second in today’s race.

At +550 odds to win, Hamlin secured his 60th career win at Las Vegas the last time the Cup Series raced at the track last October. In the last seven Las Vegas races, the driver of the No. 11 has only one finish worse than 11th.

Chase Elliott, other Cup stars enter as longshots

While many of the usual suspects are favorites to win Sunday’s race, there are a few longshots that are worth watching out for.

One of those is Chase Elliott, who goes into Sunday at +2200 to win. The driver of the No. 9 has struggled to find results at Las Vegas with one top-10 finish in the last six races.

However, Elliott knows how to win on the 1.5-mile tracks as he did last September at the Kansas Speedway.

Ross Chastain is another underdog to watch on Sunday. The driver of the No. 1, at +2800 odds to win, has bagged three top-five finishes and four top-10 efforts in the last five Las Vegas races.

Josh Berry, the defending winner of the Pennzoil 400, enters Sunday at +6500 to win. The driver of the No. 21 captured his first career win in this race one year ago after pacing the field for 18 laps.

The green flag for today’s (March 15) race is scheduled for 4 p.m. Eastern time. The race can be watched on FS1 or listened to on the Performance Racing Network.
