“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.
Only the Sean N. Parker Foundation is ranked. The Parker Institute for Cancer Immunotherapy is a public charity he founded; it is listed under Charities in their name.
Meanwhile, the homes, jets, yachts and parties we have tracked add up to $4.5 million. See what Parker spent on Rich vs Reality →
