Source: IRS Form 990-PF Part XV and Form 990 Schedule I, tax years 20192025. These are grants already paid, a record of what an organization funds rather than an open call. Private foundations rarely accept unsolicited applications and the route in is usually a program officer; grantmaking charities and associations more often run real application cycles, so check their website.
