Andrew W Mellon Foundation

The Andrew W. Mellon Foundation operates primarily through an invitation-based grantmaking model — a critical distinction that shapes every aspect of how prospective grantees should approach this funder. With $7.82 billion in assets and annual giving of $475.8 million (FY2024), Mellon is the largest private source of arts, culture, and humanities funding in the United States. Its program officers proactively identify, research, and cultivate relationships with organizations before extending a formal invitation to submit a proposal. The typical relationship progression moves from initial awareness — a program officer becoming familiar with your work through publications, convenings, or peer referrals — to informal exploratory conversations, to a formal invitation, and finally to a collaborative proposal development process that may involve multiple rounds of revision before board submission.

The foundation organizes its grantmaking around four core programs: Higher Learning; Arts and Culture; Public Knowledge; and Humanities in Place. Presidential Initiatives layer thematic priorities across these areas: Artists as Catalysts, Beyond Incarceration, Monuments and Memory, Power of the Word, Multivocality, Civic Engagement, and Puerto Rico and Its Diaspora are among the current named themes. Since a formal strategic shift in 2020, social justice is an explicit cross-cutting lens — proposals that do not engage substantively with equity, racial justice, or inclusion are increasingly misaligned with Mellon's current direction regardless of intellectual merit.

Mellon's grantee list reveals a strong affinity for established institutional partners: the American Council of Learned Societies has received $74.8 million across 28 grants; major research universities such as University of Michigan ($19.9M), UCLA ($11.8M), Johns Hopkins ($10.4M), and Cornell ($8.5M) are repeat recipients. Tides Center, functioning as fiscal sponsor, tops the list at $206.7M across 7 grants, reflecting Mellon's comfort with large, complex pass-through arrangements. First-time applicants from smaller or newer organizations will need to demonstrate organizational capacity, a track record in humanities or arts, and — ideally — a connection to existing Mellon grantees who can provide a warm introduction.

The Humanities in Place program offers the most accessible entry point with a standing rolling open application. The Higher Learning program issues periodic Open Calls for Concepts, which accept abbreviated concept-level submissions rather than full proposals. For all other program areas, the practical path is relationship-building: send a brief unsolicited inquiry to inquiries@mellon.org, attend Mellon-sponsored convenings, and publish in venues that Mellon program staff follow.

The Andrew W. Mellon Foundation's grantmaking data reflects a funder that makes large, sustained commitments to a concentrated portfolio of institutional partners. Across 3,379 tracked grants totaling $2.51 billion, the median grant is $500,000 — immediately signaling that Mellon is not a source of small project grants or seed funding. The range spans from $12,500 to $25 million, with an average of $717,751. Organizations entering the portfolio for the first time typically land in the $300,000–$750,000 range before accessing the seven-figure grants that characterize deep, multi-year partnerships.

Annual giving has followed the foundation's investment returns: FY2019 ($376.1M) → FY2020 ($527.9M) → FY2021 ($558M) → FY2022 ($688.7M) → FY2023 ($654M) → FY2024 ($475.8M). The FY2024 decline reflects normalization after a pandemic-era giving surge and some investment performance contraction. Total assets have ranged from $6.99 billion (2019) to a peak of $9.55 billion (2021), settling at $7.82 billion in FY2024 — the foundation remains robustly capitalized.

Geographic concentration is pronounced. New York-based organizations dominate with 888 of tracked grants (roughly 26% of the portfolio), followed by California (438), Massachusetts (159), DC (175), Illinois (156), Pennsylvania (122), and Texas (121). Together these seven states account for approximately 71% of tracked grantmaking. Organizations based outside major coastal metros — or in the South, Mountain West, and rural regions — face an implicit geographic disadvantage and should expect to invest extra effort contextualizing their operating environment.

Program area breakdown based on grant descriptions: Higher Learning leads, encompassing humanities fellowships (Mellon Mays, New Directions, dissertation fellowships), university humanities departments (African American Studies, Latinx Studies, Women's and Gender Studies), and prison education. Arts and Culture is second, covering performing arts organizations, museum conservation, public broadcasting (WGBH, $17.3M), and library infrastructure. Public Knowledge (digitization, open access, archival preservation) and Humanities in Place (community archives, monument interpretation, place-based storytelling) round out the portfolio.

Multi-grant relationships are the norm: the top 15 grantees have received between 4 and 22 individual grants each, confirming that Mellon treats its most trusted partners as long-term investments rather than one-time project funders.

The following table compares the Andrew W. Mellon Foundation to four peer foundations with overlapping educational, cultural, and humanities giving profiles:

Mellon dwarfs this peer group in both asset base and annual giving within the arts-and-humanities niche — it outspends Carnegie Corp by more than two-to-one in this specific domain. Carnegie Corp covers complementary terrain (education policy, democracy) with occasional overlap on higher education access, while Sloan tilts toward STEM and science communication. Knight Foundation is the most accessible to newcomers, with open applications available in journalism and community-building. Among this peer set, Mellon stands alone in its scale of humanities-specific funding and its strict invitation-first model.

For humanities-focused nonprofits and universities, Mellon often functions as the lead funder whose commitment unlocks matching capital from the National Endowment for the Humanities, state humanities councils, and peer foundations. A single Mellon grant can anchor an institution's entire humanities funding strategy — making the relationship-building investment substantial but potentially transformational.

2025-2026 has been one of the more active periods in Mellon's recent history. In July 2025, the foundation appointed Carla Hayden — the 14th Librarian of Congress — as a senior fellow, deepening its public knowledge agenda and signaling sustained engagement with national library infrastructure. Margaret Anadu, Senior Partner at private investment firm The Vistria Group, was elected to the Board of Trustees, reflecting Mellon's interest in bridging private capital with public mission.

October 2025 brought the Humanity AI announcement: Mellon joined nine other foundations to capitalize a five-year, $500 million initiative focused on artificial intelligence's impact on democracy, education, humanities, culture, labor, and security. This marks the foundation's most significant foray into technology policy, potentially opening new funding pathways for scholars and institutions working at the intersection of AI ethics and humanistic inquiry.

Earlier in 2025, Mellon launched the Jazz Legacies Fellowship — a $35 million initiative in partnership with the Jazz Foundation of America offering $100,000 in unrestricted funds plus additional stipends to elder jazz musicians. This is the largest individual artist support program Mellon has ever operated and represents a notable expansion of the Artists as Catalysts thematic priority.

In early 2026: the Literary Arts Fund was publicly introduced by President Elizabeth Alexander on PBS NewsHour (January 12); the Newberry Library received $4 million for Indigenous Studies Collections (February 4); and $1.2 million was committed for wildfire cultural preservation in Los Angeles (February 2). The Higher Learning program's 2026 Open Call for Concepts accepted submissions through February 17, 2026, with the New Directions Fellowship planning an inaugural alumni convening for May 2026 in New York.

Navigating Mellon's invitation-first model requires a sophisticated long-game strategy. The foundation explicitly welcomes unsolicited inquiries — meaning direct outreach to program staff is not only acceptable but expected for serious prospective grantees. Begin with a brief one-page inquiry (no attachments) to inquiries@mellon.org that identifies your organization's mission, the specific program area you believe aligns with your work, and a concise description of the project you have in mind. This is the required first step; do not attempt to submit a full proposal without an invitation.

Align your language with Mellon's current vocabulary. The foundation uses specific terms consistently: 'just communities,' 'critical thinking,' 'multivocality,' 'social justice,' 'monuments and memory,' 'power of the word,' 'beyond incarceration.' Proposals should engage explicitly with equity, diversity, and racial justice as central intellectual frameworks — not as add-ons. Mellon has publicly stated that social justice is a lens applied across all grantmaking since 2020, and program officers will notice immediately if a proposal reads as a pre-2020 Mellon application.

The Humanities in Place program at mellon.fluxx.io/apply/hip is the most accessible on-ramp for organizations seeking a first Mellon grant. It accepts rolling applications and focuses on place-based humanities: community archives, public history, site-based interpretation, and local storytelling. If your project touches these themes at all, submit here rather than waiting indefinitely for an invitation to other programs.

Higher Learning issues periodic Open Calls for Concepts — these are competitive but transparent. Concept-level submissions (not full proposals) are required at the first stage, which significantly lowers the preparation barrier. Monitor the newsletter at mellon.org for future calls.

Common mistakes to avoid: submitting unsolicited full proposals (they are not reviewed); applying on behalf of K-12 schools or tuition programs (explicitly excluded); framing projects as support for individual scholars without an institutional host (Mellon funds organizations, not individuals, except through named fellowships like New Directions and Jazz Legacies); and presenting proposals with no social justice framing.

Build visibility before formal outreach. Publish in humanities journals and cultural publications that Mellon staff read; present at NEH convenings, Humanities Center Directors retreats, and AAM/CAA conferences; and develop relationships with program staff at existing Mellon grantees — American Council of Learned Societies, Smithsonian, WGBH, Bard College — who can provide warm introductions.
