Key Findings – 2025 Report on Private Philanthropy

Foundation Source conducted a year-over-year analysis of the grantmaking and investing activity of more than 1,100 private, non-operating foundations within our client base. The organizations in our sample met specific inclusion criteria: each had been in existence for at least two full calendar years, remained active during the period of the study (calendar years 2023 and 2024), and had assets ranging from $1 million to $1 billion.

The findings presented herein reflect a period of relative stability in philanthropic activity, even as the broader social and policy landscape was shifting. Despite growing uncertainty from economic factors and a presidential transition, foundations maintained consistent grantmaking levels, demonstrated responsiveness to community needs, and pursued long-term growth strategies, enabling them to continue operations well into the future. The data is organized into three thematic categories, each highlighting key trends in giving and investing across the sector.
