Warren Buffett created the Giving Pledge, a campaign to convince billionaires to give away half their fortune to charity before they die. He was joined in the effort by fellow billionaire Bill Gates and Gates' then-wife Melinda French Gates. It has evolved into a global initiative with some 240 signatories from 30 countries to the pledge.

According to Forbes, the 400 wealthiest Americans have given $287 billion to charity in their lifetimes. But that accounts for just 5% of their $5.4 trillion in combined wealth and only one-third of the increase in their wealth in the past year.

Here are eight notable signers of the Pledge and how much they've given away of their wealth so far. Also, some controversies have arisen between billionaires and their charitable priorities.

Warren Buffett has given away the most money of anyone, over $57 billion

The man who started it all also happens to be the person who has donated the most over a lifetime of giving. Warren Buffett, chairman and CEO of Berkshire Hathaway ( NYSE:BRK-A )( NYSE:BRK-B ) has given away $56.7 billion over his lifetime. He has committed to giving away 99% of his estimated net worth of $143.1 billion. As a percentage of the total, Buffett has contributed about 30%.

MacKenzie Scott

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.

Anne Wojcicki

Anne Wojcicki founded 23andMe Holdings but her net worth has taken a hit as the company's fortunes declined

Anne Wojcicki became a billionaire following her company 23andMe Holding ( NASDAQ:ME ) going public in 2021. She became a Pledge signer the following year. However, as the value of her company has fallen to penny stock status, her wealth has declined with it. She has a net worth of $270 million, but how much she has donated to charity is unknown.

Susan Wojcicki and Dennis Troper

Former YouTube CEO Susan Wojcicki, and her husband Dennis Troper, signed the Pledge last year. She had an estimated net worth of $780 million at the time of her death in August. She was the sister of Anne Wojcicki.

Billionaire bickering

Some billionaires have been critical of others for not doing enough with their money to help others

Even billionaires quarrel. Tesla 's ( NASDAQ:TSLA ) Elon Musk, a Pledge signer, and French Gates had a public spat after Gates endorsed Joe Biden for president and then Kamala Harris. Musk supports Donald Trump.

He said Gates' endorsements could bring about "the downfall of Western civilization." She was nonplussed and said his criticism was "silly."

Male billionaires can do more

Twitter and Block founder Jack Dorsey has been criticized by Melinda French Gates for not being philanthropic

Gates disparaged Musk and other male billionaires such as Peter Thiel, Jack Dorsey, and Pershing Square Capital Management 's Bill Ackman for not doing enough.

Gates told The New York Times, "Well, the people you just named have not been very philanthropic yet. They use their voice and they use their megaphones, but I would not call those men philanthropists."

Musk on charitable giving

Despite being a Giving Pledge signer, Elon Musk has been skeptical of charities

Although a Pledge signer, Musk remains skeptical of charities. Forbes estimates the world's richest man with a net worth estimated at $257.6 billion has given away less than 1% of his wealth. The Times says his donations benefit himself, his partners, and his family. They point to a county impacted by debris from a SpaceX rocket that exploded and the Ad Astra non-profit school his children attend.
