    About William K Warren Foundation

    The William K. Warren Foundation makes very large, highly concentrated grants rather than many small awards. In the most recent reporting period it issued only two multi‑million dollar disbursements (both labeled as statement codes), suggesting the foundation either funds a small set of affiliated institutions or makes large institutional transfers such as endowment/capital contributions or multi-year commitments. Public purpose beyond that is not explicit from the grant descriptions provided.

    Focus Areas

    Large institutional transfers to affiliated entities or foundationsEndowment/capital funding or major gifts for long‑term sustainabilityUnrestricted or general program support to partner organizations

    Who They Fund

    affiliated institutionspartner foundations/organizationsinstitutional endowments/capital projects

    Giving Approach

    Very concentrated giving: two very large grants that together account for essentially all reported giving. Pattern suggests few, high‑dollar disbursements (likely to affiliated organizations or for endowment/capital purposes) rather than broad, program‑level grantmaking.

    About William K Warren Foundation

    The William K Warren Foundation’s recent giving is defined by two very large institutional transfers to Tulsa-based statement recipients: $22,185,143 in 2025 to Statement 29a and $21,106,890 in 2023 to Statement 30a. Those grants point to a foundation that funds through concentrated, high-dollar awards rather than a broad spread of smaller gifts. Both recipients are in Tulsa, and both awards are recorded as statement codes, which suggests transfers tied to affiliated entities, endowments, capital support, or other long-term commitments. The foundation’s profile is further shaped by the size of those disbursements relative to its reported annual grants and assets. With a latest 990 year on file of 2025 and no individual giving or program-related investments, its public grantmaking appears to operate as institutional support at a meaningful scale. The available grant descriptions do not name programmatic outcomes, but the structure of the awards indicates that the foundation’s role is less about broad grant distribution and more about concentrated support for a small number of recipients in Oklahoma.

    What William K Warren Foundation Funds

    The William K Warren Foundation’s grant descriptions center on institutional support rather than discrete project funding. One recent award went to Statement 29a in Tulsa for $22,185,143, a level consistent with long-term financial support, capital backing, or another major internal transfer. A second grant, also to a Tulsa recipient, went to Statement 30a for $21,106,890. Together, these awards show a pattern of funding that is tied to partner institutions in the same city and recorded at a scale far above typical operating grants. Because the available descriptions use statement codes, the clearest reading is that the foundation supports affiliated entities or major institutional needs. That pattern aligns with the provided focus areas of endowment and capital funding, multi-year or lump-sum contributions, and unrestricted general support.

    How William K Warren Foundation Gives

    The foundation’s grant size distribution is highly compressed: p25, median, and p75 are all $21,106,890. That indicates a very narrow band of award sizes rather than a varied grant portfolio. The recent record also shows only two grants, both multi-million-dollar disbursements in different years, which points to recurrent but infrequent institutional support. The available data suggests a foundation structure oriented around concentrated giving, with no individual grants and no program-related investments reported.

    Where William K Warren Foundation Makes Grants

    Grantmaking is entirely local in the available record: 100% of grants went to recipients in Oklahoma, and the top state by grant count is OK. Both recent recipients are in Tulsa, showing a strong city-level concentration. No non-U.S. recipient countries appear in the data. The pattern suggests that the foundation’s giving lands in the same state as its headquarters, though the geographic data specifically describes recipient locations, not headquarters.
