George Soros just gave most of his wealth to his charitable organization, the Wall Street Journal reported Tuesday.
The billionaire philanthropist transferred $18 billion to Open Society Foundations, a sprawling international group of charities that works in more than 100 countries on projects focused on refugee relief, public health and many other topics.
The $18 billion figure amounts to almost 80 percent of the financier's total net worth. Before the transfer, Soros had a net worth of $23 billion, according to a Forbes tally Tuesday. The site ranks him as the 29th wealthiest person in the world.
The donation catapulted Open Society Foundations to the front ranks of American charities based on total assets, the Journal reported, citing 2014 data. The only American charity larger than Open Society, the Bill and Melinda Gates Foundation, is also funded by a famous billionaire.
