“ The Giving Pledge was launched in 2010 by Bill Gates, Melinda French Gates, and Warren Buffett. The list of signatories includes some of the country’s wealthiest, including those who have given away the biggest sums of their fortunes, such as MacKenzie Scott and the late Microsoft cofounder Paul Allen.

While receiving more than 250 signatures from the world’s wealthiest global philanthropists, the number of wealthy signing on has dwindled in recent years. Just four pledged in 2024, and 14 signed on in 2025, according to a list of signatories compiled by the Giving Pledge. That comes even as more of the world’s wealthiest reach billionaire status each month, with Forbes’s latest estimate calculating there are more than 3,400 billionaires globally.“ finance.yahoo.com - Peter thiel actively convincing billionaires
