IndyCar’s 2026 season ends with average viewership under 1 million, according to reported figures. Multiple outlets cite an overall increase in audience size compared with earlier IndyCar seasons, indicating the series is drawing more viewers during its second year on Fox Sports.
Yahoo Sports reports that IndyCar viewership rises by 23% on average in 2026 as it completes its second season with Fox. It also notes that Fox owns one-third of the series. Forbes similarly highlights gains under the Fox arrangement, saying total viewership increases by about 80% compared with NBC’s final year in 2024.
While the outlets broadly agree on the direction of the change—higher viewing numbers under Fox—they emphasize different comparisons: Yahoo focuses on the 2026 year-over-year average increase, while Forbes frames the growth as cumulative versus the 2024 NBC period. Both accounts tie the improvements to the ongoing Fox–IndyCar broadcast partnership.
