More than 230 of the world’s wealthiest people, including Elon Musk, Bill Gates and Warren Buffett, have promised to give at least half of their fortunes to charity within their lifetimes or in their wills by signing the Giving Pledge. Some of the most affluent, including Jeff Bezos (who hadn’t signed the Giving Pledge as of early 2023) and his ex-wife MacKenzie Scott (who did sign the pledge after their divorce in 2019) have declared that they will go further by giving most of their fortunes to charity before they die.
