Formula 1 CEO Stefano Domenicali has made it clear: the championship's explosive growth in the United States is just getting started. "We're only at the beginning of our journey," he said during last weekend's Miami Grand Prix weekend—a race that once again drew a sell-out crowd.

The numbers tell a compelling story. F1's American fanbase has surged in the 2020s, with record TV audiences reported by former broadcaster ESPN. New rights holder Apple has been encouraged by 2026 viewership trends, though official figures are still being verified. What's undeniable is the live-event boom: just eight years ago, the U.S. hosted only one race in Austin with roughly 60,000 fans. Now, America boasts three Grands Prix—Miami joined in 2022, Las Vegas followed in 2023—and average attendance has skyrocketed.

Domenicali sees this as just the opening lap. "There's a lot of demand for more races in the U.S.," he noted, "but we need to manage that carefully." He compared F1's current position to its earlier, more sporadic American presence—from Detroit to Indianapolis—and emphasized the phenomenal cultural shift underway.

Still, he's realistic about the road ahead. America's "big four" sports are deeply ingrained in the national psyche, and F1 is still building that foundation. "To evolve the culture takes time," Domenicali acknowledged. "We need to keep hammering what we want to do, because the U.S. gives us a tremendous opportunity to grow."

For fans and brands alike, the message is clear: F1's American expansion is accelerating, and the best is yet to come. Whether you're gearing up for race day or just discovering the sport, there's never been a better time to be part of the journey.
