Pierre Omidyar – $7.6 billion
Best known as the founder of eBay, Pierre Omidyar and his wife plan to give away their incredible wealth. In 2001, he explained, “We have more money than our family will ever need.” He went on to add, “There’s no need to hold onto it when it can be put to use today, to help solve some of the world’s most intractable problems.” Together with his spouse, he launched the Humanity United Foundation that supports nonprofits focused on anti-slavery.
