Diana Davis Spencer Foundation

The Diana Davis Spencer Foundation operates as one of the most significant and least publicly visible conservative family foundations in the United States, with $1.35 billion in assets under management. Founded in 2007, it builds on two prior philanthropic vehicles — the Shelby Cullom Davis Foundation (1962) and the Kathryn W. Davis Foundation (2004) — rooted in a multi-generational commitment to international affairs, education, and founding American principles. Ambassadorial and diplomatic heritage runs deep: founder Shelby Cullom Davis served as the longest-tenured American ambassador to Switzerland, shaping the foundation's sustained emphasis on international affairs.

The foundation's giving philosophy centers on five explicit pillars: Founding Values (limited government, individual responsibility, fidelity to the Constitution), Education (K-12 through graduate level), Entrepreneurship (youth economic empowerment), Public Policy (defending economic and political freedoms), and National Security (military, intelligence, counterterrorism). This ideological coherence is non-negotiable — organizations that do not demonstrably align with conservative and free-market principles will not be funded regardless of program quality or community need.

All grantmaking occurs on a strictly invitation-only basis. There is no open application cycle, no published RFP, and unsolicited proposals are explicitly rejected. The foundation's model resembles a curated portfolio approach: they build long-term relationships with a defined set of high-trust grantees, making repeat and multi-year grants to proven partners. Of the top 50 grantees in their IRS filing history, the median organization received 4 separate grants — deep relational investment rather than one-time program funding.

Organizations new to this funder face a genuine access challenge. The path typically runs through existing board relationships, thought leadership recognition, or connections through allied organizations in the conservative policy ecosystem — Heritage Foundation, Hillsdale College, Fund for American Studies, Federalist Society, American Council of Trustees and Alumni. Executive Chairman Diana Davis Spencer and CEO Abby Spencer Moffat are the ultimate decision-makers; reaching them through warm peer introductions is far more effective than cold outreach.

For first-time applicants, the recommended approach is to submit a brief organizational inquiry via the website contact form at ddsfoundation.org/contact-us/, providing contact information and a concise two-paragraph project description. Emphasize alignment with their specific pillars — especially Founding Values, National Security, or Entrepreneurship — and cite concrete outcomes rather than aspirational program goals. An invitation to submit a full proposal, if it comes, may arrive 3-6 months after the initial inquiry.

The Diana Davis Spencer Foundation's grantmaking displays distinct financial patterns across its documented history. Across 718 tracked grants totaling $365.5 million, the average grant is $509,094 and the median is $120,000 — a meaningful gap indicating that a small number of transformational, multi-million-dollar commitments coexist alongside many smaller programmatic awards.

Annual giving has been volatile but substantial. FY2024 recorded $67.3 million in total giving across 134 grants (average ~$502K per grant), while FY2023 saw $64.8 million across 154 grants (~$421K average). The foundation's two largest spending years — FY2020 ($124.3M in total giving) and FY2022 ($141.9M) — coincide with large contributions to Donors Trust, the conservative donor-advised fund platform that received $67 million across 10 grants in the database. This means DDSF uses DAF vehicles as a strategic pass-through for flexible regranting, and total outflows in high-activity years substantially exceed direct program grants.

Grant size follows clear patterns by relationship depth. New grantee relationships typically begin in the $25,000–$150,000 range. Established partners often receive $250,000–$1 million annually. Transformational commitments — exceeding $3 million — are reserved for the foundation's inner circle: Masters School ($48.2M across 5 grants, including campus construction and endowed faculty), Texas A&M University Bush School ($33.5M across 6 grants for the DC-based national security graduate program), Wheaton College ($12.1M across 4 grants for a scholarship endowment and Discovery Center), and the Heritage Foundation ($11.5M across 9 grants for public policy research and election integrity).

Geographic concentration is pronounced: Washington DC-based organizations received 30% of tracked grants (217 grants), Virginia 14% (103 grants), New York 11% (77 grants), Maine 9% (64 grants), and Maryland 8% (60 grants). The Maine cluster reflects the Davis family's long historical ties to coastal Maine through grantees like Maine Seacoast Mission ($1.15M) and Maplebrook School ($1.5M).

By program area, education (higher ed and K-12 private schools) accounts for an estimated 40% of total dollars, national security and public policy think tanks ~35%, entrepreneurship ~10%, health and medical research ~8% (Jackson Laboratory $2M+, Mayo Clinic $2M, Foundation Fighting Blindness $2M), and arts and media ~7%. The grant range per the foundation's own data is $1,000 to $7,000,000, with a stated average of $406,907.

The table below compares Diana Davis Spencer Foundation to its five closest asset-size peers drawn from the foundation database.

Among comparable $1.3B+ foundations, Diana Davis Spencer stands out for its ideological specificity — arguably the most explicitly conservative, founding-values focused of any billion-dollar private foundation in the US. The Joyce Foundation is the notable outlier: it accepts open LOI submissions on a published grant cycle, making it by far the most accessible of the cohort for organizations without existing relationships. DDSF's national security emphasis is unique in this peer group — no comparable family foundation in this asset range maintains comparable concentration on military, intelligence, and counterterrorism programming alongside conservative policy and education.

As of early 2026, no major press releases or new program announcements have emerged from the Diana Davis Spencer Foundation, consistent with its historically low-profile communications posture. The foundation rarely issues proactive public statements beyond IRS filings and occasional partnership announcements.

The most recently confirmed major commitment is the Pentagon Memorial Fund grant — $1.25 million in grants paid, with the total pledge described as $5 million across a multi-year installment schedule — toward the planned 9/11 Pentagon Memorial Visitor Education Center. CEO Abby Spencer Moffat publicly described the gift as aligned with the foundation's commitment to "preserving American history and advancing national security."

FY2024 (the most recent 990 period available) shows 134 grants totaling $67.3 million in total giving, with $79.2 million in grants paid — the difference reflecting multi-year grant installments from prior commitments. This represents a slight uptick from FY2023's $64.8 million and is consistent with the foundation's normalized $50-70M annual range outside its exceptional DAF-transfer years.

The foundation launched a dedicated Grantee Community portal (ddsf.my.site.com/s/), a Salesforce-based platform for current grantees for reporting and relationship management. This infrastructure investment signals growing organizational sophistication even as the invitation-only posture toward new applicants remains unchanged.

Leadership compensation remained stable: CEO Abby Spencer Moffat earned $832,604 and Executive Chairman Diana Davis Spencer received $776,545 in the most recent reporting year. No public leadership transitions were identified in available data through early 2026.

Understand the access model before anything else. This foundation does not fund strangers. The invitation-only model means that formal program quality matters less than proximity to the foundation's leadership or grantee network. Before spending any time on a proposal, map your board, leadership, and advisory council for connections to current DDSF grantees: Heritage Foundation, Hillsdale College, Texas A&M Bush School, Wheaton College, Fund for American Studies, Federalist Society, American Council of Trustees and Alumni, Network for Teaching Entrepreneurship, JINSA, and Victims of Communism Memorial Foundation are all active partners who can provide credible introductions.

Use the contact form strategically. The inquiry process at ddsfoundation.org/contact-us/ accepts brief organizational descriptions. Keep to two paragraphs: (1) your mission, primary program, and one specific outcome metric; (2) the specific project you seek support for and which DDSF pillar it serves most directly. Do not attach a full proposal, financials, or video links at this stage. The goal is prompting a conversation invitation, not overwhelming a small program staff.

Use their exact language. The foundation's materials consistently emphasize "limited government," "individual responsibility," "self-determination," "founding documents," "free enterprise," and "national security." Mirror this framing precisely in your inquiry and any subsequent proposal. Avoid neutral or progressive-coded language even if technically accurate — DDSF's giving is explicitly ideological, and language signals alignment or misalignment immediately.

Size your first ask appropriately. New grantee relationships in the database cluster in the $25,000–$150,000 range. Transformational multi-million-dollar grants come only after demonstrated performance across multiple grant cycles. Plan your entry-point request accordingly — a discrete, well-defined project rather than general operating support is more likely to succeed as a first grant.

No deadline-driven cycle applies. The foundation publishes no grant cycle or proposal deadlines. Inquiries can be submitted year-round, but fall (September–November) and spring (February–April) may align with board activity given the DC/Maryland base. One polite follow-up after 60 days of no response is appropriate; additional follow-up is counterproductive.

Prepare for site visits if relationships progress. DDSF program staff are engaged with active grantees, particularly in Maine and the DC metro area where grantee density is highest. Organizations that advance in the relationship should be prepared to host staff and demonstrate real-world program operation, not just reporting documents.
