IMSA News: 12 Hours of Sebring had a record breaking crowd

Posted by AR1 staff

On the heels of record attendance and strong viewership performance from January’s Rolex 24 At Daytona, the numbers are in from the Mobil 1 Twelve Hours of Sebring and they are similarly impressive.

Officials from Sebring International Raceway confirmed an all-time attendance record for the 74th running of the once-around-the clock classic, with more than 115,000 attendees passing through the gates over the four-day period from March 18-21. At-track attendance was reinforced by substantial increases in merchandise sales, with IMSA seeing a 32 percent increase year over year and Sebring International Raceway experiencing a 19 percent increase. IMSA and Sebring saw a combined 25 percent increase over 2025.

At-track performance is only part of the story, however, as IMSA’s domestic and global broadcast offerings continue to build momentum. The total live global audience reached well over one million viewers, bolstered by a 37 percent year-over-year increase in reach for Peacock’s domestic streaming audience and a 23 percent increase for international streaming on the official IMSA YouTube channel and IMSA.tv along with international linear television distribution through Greenlight International.

IMSA’s official social media channels also continued to grow substantially, with 73,000 total new followers gained. The channels achieved 52 million video views, which was responsible for a 13 percent increase year over year.

“The momentum behind IMSA has never been stronger,” said IMSA President John Doonan. “From a record-setting crowd at Sebring to continued growth across broadcast, streaming and digital platforms, these results reflect the passion of our fans, the strength of our partners and teams, and the global appeal of sports car racing. As we head into the heart of the 2026 season, we’re encouraged by the trajectory of the championship and excited about what’s ahead.”

Next up for the IMSA WeatherTech SportsCar Championship is the annual visit to the iconic Southern California street race, the Acura Grand Prix of Long Beach, on April 17-18. Live NBC network television coverage of the 100-minute race airs at 4 p.m. ET on Saturday, April 18. IMSA PR
