NBC Takes Over NASCAR Coverage for Final 14 Races of 2025 Season

The 2025 NASCAR season is intensifying as the final 14 races, including the playoff run, air on NBC and USA Network, starting at Iowa Speedway and concluding at Phoenix Raceway. NBC Sports maintains a consistent broadcast team with Leigh Diffey, Steve Letarte, and Jeff Burton leading coverage, while streaming options are available across NBC.com, the NBC Sports app, USA Network app, and Peacock for select races. Recent viewership trends show a decline in ratings for NASCAR events, with the Brickyard 400 drawing 2.449 million viewers on TNT, down significantly from 3.63 million in 2024, and the Truck Series race at Lucas Oil Indianapolis Raceway Park experiencing a 21% drop to 341,000 viewers on FS1. Despite this, competitive excitement continues, highlighted by Bubba Wallace's first 2025 Cup Series win at Indianapolis and upcoming races like the Iowa Corn 350 where betting odds are closely watched. Concurrent IndyCar races, such as the one at Laguna Seca, are drawing respectable audiences despite competition from NASCAR's marquee events, with 734,000 viewers on Fox marking one of the most-watched IndyCar broadcasts at that venue since 2019.
