GT World Challenge America: A new three-hour race format will replace the traditional pair of 90-minute races. The season will still conclude with the Indianapolis 8 Hour.

GT America: The series will welcome Cup cars to its grids for the 2026 season, allowing race-prepped Porsche Cup, Lamborghini Super Trofeo and Ferrari Challenge entries to join the series. The Masters Award also returns, celebrating the highest-finishing driver aged 55 and older at every event.

TC America: TC America will shift to a two-race, 35-minute sprint format per weekend aimed at maintaining accessibility and affordability for teams and drivers.

Pirelli GT4 America: The GT4 series will continue with its 60-minute doubleheader format at every round. However, the three-hour Lone Star Enduro at Circuit of The Americas will return for the third consecutive season.
