Dashboard Thesis
Biggest is NASCAR.
Hottest is F1.
The U.S. market is not one scoreboard. This view splits it into reach, money, and future relevance so you can see who owns the scale, who owns the premium dollars, and who owns the next wave.
Scale leader
NASCAR
Largest domestic audience footprint and biggest rights stack. Still the heavyweight.
Premium / future leader
F1
Wins the cool, youth, and hospitality game. Smaller than NASCAR, hotter than NASCAR.
Asymmetric asset
IndyCar
The Indy 500 is a monster. Weekly baseline is smaller, but the crown jewel is real.
