Amid a tumultuous stock market that caused many fortunes to plummet, the top philanthropists in the United States donated more money than in each of the previous two years. The nation’s 25 most generous donors have given an estimated $196 billion over their lifetimes through the end of 2022, up from $169 billion a year ago. The $27 billion increase in giving in the past year outpaced the $20 billion gain from the two prior years and was more than double the amount the top 25 gave away in 2018.
Despite the decline in fortunes, these philanthropists, who are collectively worth $936 billion, have continued to give generously. Sixteen of them have signed The Giving Pledge, vowing to donate at least half of their wealth during their lifetime or after their death. Three of them – Chuck Feeney, Denny Sanford, and George Soros – have already fulfilled their pledge.
Here’s the full list of America’s 25 most generous givers;

Billions have also gone to four charities set up by his three children and his late wife, including $760 million just before Thanksgiving last November.

He donated $100 million to make it a reality in 2013.
