Letterman, [[Bobby Rahal]], and [[Mike Lanigan]] of [[Mi-Jack Products]] co-own [[Rahal Letterman Lanigan Racing]], an auto racing team competing in the [[WeatherTech SportsCar Championship]] and [[IndyCar|NTT IndyCar]] series. The team has twice won the [[Indianapolis 500]]: in [[2004 Indianapolis 500|2004]] with driver [[Buddy Rice]], and in [[2020 Indianapolis 500|2020]] with [[Takuma Sato]].

[[The Letterman Foundation for Courtesy and Grooming]] is a private foundation through which Letterman has donated millions of dollars to charities and other nonprofit organizations in Indiana and [[Montana]], celebrity-affiliated organizations such as [[Paul Newman]]'s [[Hole in the Wall Gang Camp]], Ball State University, the [[American Cancer Society]], the [[Salvation Army]], and ''[[Médecins Sans Frontières]]''.
