Of 32 on the ranking, least generous first

“Put in” is what the foundation received, which the donor can deduct from taxes in the year it goes in. Private foundations only have to pay out about 5% of their assets a year; the rest can sit invested.

Two Adelson foundations file with the IRS; both are counted.

Meanwhile, the homes, jets, yachts and parties we have tracked add up to $95 million. See what Adelson spent on Rich vs Reality →
