Operating Foundations: What They Are and How They Differ From Grantmakers

Cover illustration for Operating Foundations: What They Are and How They Differ From Grantmakers

Operating foundations run their own programs rather than (mostly) giving grants. Learn what an operating foundation is, how it differs from a grantmaking foundation, and how to engage one.

Not every foundation is a grantmaker. Some private foundations primarily do the charitable work themselves, running research institutes, museums, schools, and direct-service programs.

These are private operating foundations, and they’re a real but often misunderstood category. If you treat one like a typical grantmaker, you’ll send a proposal to an entity that doesn’t really make outbound grants. Knowing which foundations are operating, and how to engage with them, saves time and reveals partnership possibilities you might otherwise miss.

This guide explains what operating foundations are and how to think about them in your grant strategy.

TL;DR: Quick Answers

How Operating Foundations Work

A private operating foundation is a private foundation that the IRS recognizes as meeting specific tests showing it conducts charitable activities directly. Examples include certain research institutes, museums, libraries, historic sites, and some education-focused foundations.

Operating foundations still file the Form 990-PF like other private foundations, but they qualify for somewhat different distribution rules because most of their giving is internal, paid to their own programs and staff rather than out as grants.

The Getty Trust (which runs museums and a research institute), the Howard Hughes Medical Institute (which conducts medical research), and the Carnegie Endowment for International Peace are well-known examples; many smaller operating foundations run specific programs or sites.

It helps to keep operating foundations in proportion to the broader foundation landscape. According to Giving USA (2025 report), foundations accounted for 19% of all U.S. charitable gifts in 2024, a share that has climbed from roughly 7% back in 1984. And Candid notes that total foundation investments equal about 3% of the entire U.S. stock market. Operating foundations are a slice of that world that mostly spends on its own programs rather than granting outward, useful context when you’re deciding where to aim your funder research.

How They Differ From Grantmaking Foundations

For grant seekers, the key distinction is:

A few operating foundations make significant outbound grants alongside their own work; many make few or none. The 990-PF will tell you which.

How to Spot an Operating Foundation in Research

When researching a funder:

Many grant databases flag operating-foundation status.

How to Engage Operating Foundations

If an operating foundation isn’t a grant source, what’s the value of knowing about them?

1. As partners. Operating foundations often run research, education, or program work that overlaps with yours. Partnership, joint projects, programmatic collaboration, content sharing, can be more accessible than a grant.

2. As convenors. Many host conferences, fellowships, and learning communities that you can participate in.

3. As employers and contractors. Operating foundations hire staff and contract with researchers and practitioners.

4. As thought leaders. Their published work often shapes the field; engaging with it strengthens your own work.

5. As occasional grantmakers. Some do make limited grants; treat these like any other private foundation, see private vs. public foundations and family foundation grants.

Where Operating Foundations Fit in Your Strategy

Most of your 12-month grant strategy focuses on grantmaking foundations and government funders. Operating foundations belong in your partnership and field-building strategy, not your grants pipeline:
