26 of them, led by the largest by dollars paid, have their own page with the application terms as filed, every recipient, and the trustees. The rest are listed here in full. Where a cell says n/a the filing does not carry that figure: a first-time recipient share needs more than one year of grants on record, and the asset figure comes from the IRS business master file, which does not cover every foundation.
Each figure comes from each foundation's latest filed year, 2022 or later. A foundation is listed when its Form 990-PF says giving is not restricted to preselected organizations and it paid at least 5 grants totaling $100K or more that year. Grants and application terms come from each foundation's latest IRS 990-PF e-file return. The newest tax year is partial until the IRS finishes releasing it. Grants are de-duplicated on funder, year, recipient and amount, so identical repeat grants count once and totals can run low. Full method.
