The NTT IndyCar Series has experienced significant growth in viewership and attendance during its second season with FOX Sports. Reports indicate that the 2027 season averaged 1.68 million viewers per race, a 23% increase over the previous year and the highest average TV rating for the series since 2008.

Key events driving this growth included the 110th Indianapolis 500, which drew 6.6 million viewers, and the Washington D.C. street race, which attracted 3.2 million viewers. In-person attendance also rose by approximately 20 percent, highlighted by a sellout at the Indianapolis Motor Speedway and a crowd of 215,000 at the Freedom 250 Grand Prix of Washington, D.C.

Industry analysts and Penske Entertainment CEO Mark Miles attribute this upward trend to enhanced promotional strategies and the partnership with FOX Sports, which Miles described as an ‘incredible new era’ for the series.
