Heir to the Vanderbilt fortune?

Does anyone even have a m fortune compared to the amount Cornelius had made? I know his son Wiliam Henry Vaderbilt received something like 95% of the inherence, so who is the current holder of the family forture? (P.S Yes i know Gloria received $ as a child, and she was in fashion & furnishing and that her son is CNN's Anderson Cooper. Also, I know that Biltmore Estates is still owned by William Cecil, grandson of George Vanderbilt, and operated by Bill Cecil Jr.) Anyways, thanks...just curious if the family has flourished even greater than the Commodore. Thanks!
