Jeff Bezos has stated in the past that he intentionally, and on a schedule, sells around 1 billion dollars worth of Amazon stock a year in order to fund other projects, such as Blue Origin, the space program. In the last year, however, he has garnered around $6 billion from stock sales. In August of 2019 he sold $2.8 billion worth of stock, and so far this week another $3.4 billion has been sold. This is much higher than his usual, and supposedly preferred, $1 billion a year. Is this money going to Blue Origin or some other Amazon holding? Neither Bezos nor Blue origin has made any comment, and speculation is wild.
