Ratings for Prime Video's Cup Series race in Mexico City achieve feat not seen in nearly a decade

Not only was that the second-highest audience of the four Prime Video races, only behind the streaming platform's debut for the Coca-Cola 600, it featured its youngest audience yet and for any Cup Series race since 2017. (While Stern originally mentioned that the race had the lowest audience for any Cup race since 2017, he clarified that he was referring to the age of the audience and not the number of viewers.)

Fans not only tuned into the race itself, but the majority of them stayed around for the post-race show that followed, which totaled 1.07 million viewers, the largest of any of Prime Video's four races to date.

Stern also noted that the median age of Prime Video viewers through its four races so far is 56.0, which is more than six years younger than the median this year during Fox Sports' coverage (62.8). 

While Prime Video has clearly gained a younger audience by the numbers, it was previously reported following the Coca-Cola 600 that it lost a lot of the older population.

That may be true, but it is hard to discredit what Prime Video has been able to accomplish in just four races, especially compared to other forms of motorsports.

The Cup Series race was one of three major races going on Sunday. The other two, Formula One's Canadian Grand Prix and IndyCar's Bommarito Automotive Group 500 at World Wide Technology Raceway, were on broadcast television.

According to The Athletic's Jeff Gluck, the Cup race performed better than both of them, with the Formula One race getting 1.57 million viewers on ABC and IndyCar attracting 1.2 million on Fox.

That says a lot, given this is the first time that NASCAR has been exclusive to a streaming platform. Each of the four races have delivered something compelling in one way or another to top it all off.

From Ross Chastain's last-to-first drive to win the Coca-Cola 600 and Ryan Blaney's first win of the season under the lights at Nashville to Denny Hamlin's fuel-mileage win at Michigan and Shane van Gisbergen's win in the inaugural Cup Series race in Mexico City, Prime Video has delivered excellent coverage of each race with top-notch analysis and extensive pre -and post-race coverage.

This Sunday's return stateside at Pocono Raceway (2 p.m. ET) will be the final race of Prime Video's 2025 coverage. Despite the unknowns beforehand, the streaming platform has had a successful start to its NASCAR coverage and the ratings certainly back that up.
