The 2026 NASCAR season continues in Las Vegas, Nevada, this weekend, and the preliminary entry lists for the Cup Series and O'Reilly Auto Parts Series have now been revealed.

With no Truck Series action this weekend, the O'Reilly Auto Parts Series is first up on Saturday, with all of their practice, qualifying (Noon ET and 1:05 pm ET, CW App) and race action (5:30 pm ET, CW) packed into one day at Las Vegas Motor Speedway.

Cup Series action, meanwhile, will be spread across the weekend, with practice and qualifying on Saturday (2:30pm ET and 3:40pm ET, Prime Video) and the race on Sunday (4pm ET, FS1).

The Cup Series field is currently slated to consist of 36 cars this weekend, with no open entries into the event. Alex Bowman is currently listed to be in the No. 48; however, Hendrick Motorsports has not confirmed his status, and this is subject to change given that he missed last weekend's race due to a medical diagnosis of vertigo.

In the O'Reilly Series, meanwhile, 41 drivers have entered, including multiple Cup Series stars, meaning that three cars will not qualify for the race.
