Fox averages 3.2m viewers for 2025 Nascar Cup Series

• All-Star Race averages 1.97m viewers on FS1
• F1 sees second-largest audience for Imola on ESPN2 (1.09m viewers)
• IndyCar gears up for Indy 500 with 924k viewers in qualifying

Fox averaged 3.2 million viewers for its segment of the 2025 Nascar Cup Series after the All-Star Race posted an average audience of 1.97 million on FS1.

The 14th and final Cup Series race on the Fox slate saw a 23.6 per cent year-over-year (YoY) decrease on the 2024 edition, which averaged 2.57 million viewers, despite the general consensus being that this was one of the better All-Star events in recent seasons.

With Fox focusing its marketing budget on this weekend’s Indianapolis 500, the All-Star Race appears to have suffered, with this year’s edition being the first to drop below two million viewers.

Year-to-date (YTD) average viewership continues to trend downwards for the Cup Series as it was sitting at 3.36 million viewers at the same point last season. That figure was itself a decrease from 2023 (3.5 million viewers) and 2022 (3.92 million viewers) respectively.

In terms of the average viewership on Fox, 2025 represents a slight decline on the 3.22 million viewers from last season.

Just five races aired on the main Fox channel, which resulted in the highest percentage of races broadcast on FS1 ever. Ultimately, this was always going to result in an audience decline this season.

Dig deeper into the numbers, though, and the broadcaster actually averaged its largest audience for its Nascar coverage on the main Fox channel since 2022 and its highest average viewership on FS1 since 2021.

Attention now shifts to the first-ever Cup Series event aired exclusively on a streaming platform as Prime Video begins its five-race broadcast run with the Coca-Cola 600 in Charlotte on 25th May.

Meanwhile, qualifying for the Indy 500 averaged 924,000 viewers on Fox, down from 1.15 million viewers last season when NBC Sports held the rights. The series will hope that audiences are saving themselves for the main event.

Formula One, though, saw 1.09 million viewers tune in to watch Max Verstappen’s dominant victory at the Emilia Romagna Grand Prix on ESPN2.

In what was likely the series’ final visit to Imola Circuit, at least in the near future, the race saw a 26.5 per cent YoY increase in viewership and recorded the second-largest US audience for the event.

Formula One’s YTD viewership in the US now sits at 1.21 million viewers, which is lower than both the 2023 and 2022 seasons. However, comparing audience sizes in this manner is misleading as the order of the Formula One calendar has changed significantly from year to year.

When comparing just the event averages for races held so far this year, the figure of 1.21 million sits only behind the 2022 average of 1.25 million.
