Pinault bought his first significant painting, Cour de ferme by Paul Sérusier, in 1980. He collected art of the 20th century (Mondrian, Picasso, Man Ray, ...) before following contemporary art and artists (David Hammons, Rudolf Stingel, Damien Hirst, Koons, Subodh Gupta, Paul McCarthy, Bruce Nauman, Donald Judd, Robert Ryman, ...). In 2019, the collection counts around 5,000 works.
