MacKenzie Scott, former wife of Amazon ( NASDAQ:AMZN ) founder Jeff Bezos, received $38.3 billion as part of her divorce settlement in 2019 and immediately began her philanthropic efforts. In that time, she has donated $16.6 billion of her estimated $35.3 billion net worth, or 32% of the total. Scott targets her charitable donations to economic issues and racial and gender equality. Bezos himself, with a $196 billion net worth, is not a Pledge signer.
