Button will race the #15 Rick Ware Racing Ford Mustang with support from Stewart-Haas Racing at COTA, where he will also face 2007 F1 champion Kimi Raikkonen in a third Trackhouse Racing Chevrolet.
It will be Button's first appearance in any division of NASCAR and comes a few months ahead of his planned assault on the Le Mans 24 Hours in a Next Gen Cup car prepared by Hendrick Motorsports. There, Button will share the car with Jimmie Johnson and Mike Rockenfeller as he makes his first attempt at the endurance classic since 2018.
