I know he is basically guaranteed to be running all of these sales off a sale schedule set far in advance for obvious reasons. However, I'd probably be doubling up those $1 billion sales until/unless this market gives out.
Raising $6 or $10 billion - enough to fund Blue Origin for maybe a decade - by selling out of a $94 billion base, sure beats doing the same out of $26 billion (where his net worth was at just ~33 months ago).
