Buffett Donates $2.8 Billion, Breaks Personal Giving Record. Warren Buffett has bested his own personal philanthropy record once again, donating $2.8 billion to the Bill and Melinda Gates Foundation and several other charities as part of his annual giving pledge. The gifts given Monday top last yearâs $2.6 billion donation.
It is these vast holdings that help fund the Gates' donations. And although Gates has given an astounding $38 billion to his charitable foundation, thanks to Larson, he's getting richer faster than he can give his money away. His $81.6 billion is nearly $6 billion more than it was as of March 2014, when he was worth $76 billion, we reported at the time. And $76 billion was $9 billion more than he was worth in March, 2013.

It was a rare occasion where the two men socialized with each other.
