Bloomberg tracks SBF's wealth on a daily basis. Currently it's at $15.6 billion, on an increasing trend despite/because of this news, though down from his March peak of $23 billion. Note that Bloomberg's graph makes the horrendous choice of putting the X axis at the historical minimum of his wealth rather than at zero.
EDIT: I am not sure if they've updated it to reflect this news, actually.
Sources: SBF's Twitter thread, in the news.
In particular, I'm interested how will this influence SBF's wealth and thus activities such as Future Fund.
