The 25 “most philanthropic” American billionaires have given away a total of $169 billion in their lifetimes and are still richer than ever, Forbes reports.

The $169 billion estimate as of the end of 2021 is up significantly from $149 billion the previous year, thanks in part to the billionaires being collectively $150 billion (on average, 18 percent) richer than they were in 2020. The top giver in 2021 was Warren Buffett, whose annual donations of Berkshire Hathaway shares to the Bill & Melinda Gates, Susan Thompson Buffett, Sherwood, Howard G. Buffett, and NoVo foundations were valued at $4.1 billion. MacKenzie Scott, who gave a total of nearly $2.74 billion to 286 organizations in June and another round of gifts in December but without disclosing dollar amounts or recipients, is not far behind, and may even be ahead of, Buffett.

Buffett also topped the list in terms of lifetime giving, at $46.1 billion, followed by Bill Gates and Melinda French Gates ($33.4 billion), George Soros ($18.1 billion), Michael R. Bloomberg ($12.7 billion), Scott ($8.61 billion publicly announced), Charles F. Feeney ($8 billion), Gordon and Betty Moore ($5.5 billion), Jim and Marilyn Simons ($3.3 billion), Phil Knight and family ($3.1 billion), and Mark Zuckerberg and Priscilla Chan ($3 billion). New to the list in 2021 are Scott’s ex-husband, Jeff Bezos (16th, $2.1 billion), who stepped down as Amazon CEO in July, and Facebook co-founder Dustin Moskovitz and his wife, Cari Tuna (22nd, $1.44 billion).

Seventeen of the top 25 lifetime givers have signed on to the Giving Pledge, promising to donate at least half their fortunes to charity over their lifetimes or upon their deaths. Yet only two—Feeney and Soros—have met that goal so far, Forbes notes, and nearly two-thirds have yet to give away even a quarter of their wealth.
