Artist Foundations’ Net Worth Has Nearly Tripled to $9 B., Led by Cy Twombly Foundation’s $1.5 B. in Art and Assets

New research from the Aspen Institute’s Artist-Endowed Foundation Initiative (AEFI) reveals that artist-endowed foundations in the U.S. now control roughly $9 billion in assets, nearly triple the $3.5 billion reported in 2011 and up 17% from $7.7 billion in 2018. The Cy Twombly Foundation leads with $1.5 billion in art and assets, followed by foundations for Alexander Calder, Joan Mitchell, Helen Frankenthaler, and Robert Rauschenberg, each holding over $500 million. The data, drawn from public tax forms, shows that just five of roughly 500 foundations account for more than half the total, with most established by postwar American artists born before 1931.
