New York (AP) _ Amazon founder Jeff Bezos said he will give away the majority of his wealth during his lifetime, becoming the latest billionaire to pledge to donate much of his vast fortune.

Bezos, whose “real-time” worth Forbes magazine estimates at roughly $124.1 billion, made the announcement in a joint CNN interview with his girlfriend Lauren Sanchez that was released on Monday. The billionaire didn’t specify how or to whom – he will give away the money, but said the couple were building the “capacity” to do it.

“The hard part is figuring out how to do it in a levered way,” Bezos said during the interview. “It’s not easy. Building Amazon was not easy. It took a lot of hard work and very smart teammates. And I’m finding and Lauren’s finding – that philanthropy is very similar. It’s not easy. It’s really hard.”

Bezos had been criticized in the past for not signing the Giving Pledge, the campaign launched by Bill Gates, Melinda French Gates and Warren Buffet to encourage billionaires to donate the majority of their wealth through philanthropy.

His ex-wife McKenzie Scott signed that pledge in 2019 and has since emerged as a formidable force in the world of philanthropy, showering charities throughout the country with unexpected – and often secretive – contributions.
