TV News: Average TV Viewers for all series in 2025
With the NASCAR season now over, here is a current list of 2025 Auto Racing events ranked by the average number of US TV viewers:
Number of series events over 1 million viewers:
- NASCAR Cup: 38
- NASCAR Xfinity: 21
- Formula 1: 17 (Four races still to run)
- IndyCar: 5
- NHRA: 2
- ARCA: 1
This looks particularly bad for IndyCar given that all their races were on linear network TV FOX. While the Indianapolis 500 drew the most viewers of any race in 2025, the remainder of the series left a lot to be desired. It is clear now that Formula 1 is the most popular open-wheel series broadcast in the USA. If all the Formula 1 races were on ABC, like IndyCar was on FOX, the Formula 1 numbers would be much higher.
Of course NASCAR is still king, but their number of TV viewers is way down from years ago.
