Large philanthropic foundations can exercise substantial influence over public policy, research, and service delivery. The problem is not philanthropy itself. It is the mismatch that arises when private institutions acquire governance influence without accountability calibrated to the scale of that influence.
When Scale Changes the Character of Giving
The largest foundations are not merely enlarged versions of local charity. Their resources permit sustained intervention across whole fields. In 2024, the Gates Foundation reported $8.015 billion in charitable support, including $354 million classified under Global Policy & Advocacy and $784 million under its United States Program. The Walton Family Foundation reported awarding $548.8 million in grants that year. Bloomberg Philanthropies has described work that trains mayors, supplies technical assistance, supports teams embedded in city halls, and helps governments test and replicate policy models. These institutions do not all have identical legal structures—Bloomberg Philanthropies encompasses foundation, corporate, and personal giving—but together they illustrate the reach of organized philanthropy at this scale.

Scale changes what a grant can do. A foundation may finance the research through which a problem is defined, support organisations that communicate a preferred interpretation, fund demonstration programmes that make one model visible, pay for evaluation of that model, and assist the institutions expected to adopt it. None of these acts alone determines public policy. Together, however, they can shape the menu from which policymakers choose: which evidence exists, which experts are available, which proposals appear tested, and which organisations possess the capacity to advocate or implement.
The mechanism is visible in foundations’ own disclosures. The Gates Foundation says that most of its grantmaking is proactive: it identifies organisations suited to projects it has initiated and invites proposals. The Walton grant database records support for research and communications concerning public education, upward mobility, and school governance. Bloomberg Philanthropies explicitly describes helping local governments strengthen data use, develop solutions, and spread policy models among cities. These examples do not establish that the resulting policies are wrong or that public officials are controlled by donors. They establish the narrower point: grantmaking can organise knowledge, capacity, and attention around selected priorities.

What Foundation Law Governs
Private foundations are not unregulated. Federal law requires annual returns, and Form 990-PF filings are generally open to public inspection. The tax code imposes rules concerning self-dealing, distributions for charitable purposes, excess business holdings, jeopardising investments, and taxable expenditures. The commonly cited payout rule is more precise than a simple requirement to spend five percent of all assets: a foundation’s minimum investment return is generally five percent of the net value of assets not used directly for exempt purposes, and that figure supplies the base for calculating its distributable amount. IRS guidance on private-foundation excise taxes; IRS minimum-investment-return guidance; IRS disclosure requirements.
The political restrictions also require precision. Section 501(c)(3) organisations must refrain from intervening in campaigns for public office. Private-foundation expenditures for direct or grassroots lobbying generally trigger substantial excise taxes, while nonpartisan research, requested technical assistance, and broad issue advocacy may remain permissible. Foundations can also make grants to governmental units for public or charitable purposes. IRS campaign-intervention guidance; IRS lobbying guidance; IRS guidance on grants to governmental units.
These constraints are real. Foundations have governing boards, face state-law requirements, file public tax returns, enter grant agreements, and may be audited or penalised. Large foundations may also publish financial statements, grant databases, evaluations, and explanations of strategy. The accountability gap therefore is not an absence of all accountability. It is a mismatch between the questions the existing framework asks and the power that policy-facing grantmaking can produce.
The legal framework principally asks whether assets are being used for recognised charitable purposes and whether prohibited transactions have occurred. It does not ordinarily ask whether a grantmaking agenda is representative of affected communities, whether one research programme has crowded out competing approaches, whether a public agency has become dependent on private support, or whether the concentration of agenda-setting power is democratically legitimate. Those are governance questions rather than conventional tax-compliance questions.
The Nature of the Gap
A foundation grant is not a statute, and a donor cannot formally command a legislature or public agency merely by offering money. Public officials remain responsible for the decisions they accept and implement. Foundations can also take risks, support neglected causes, and finance experimentation that political institutions avoid. Their independence is often part of their value.
But governance influence does not require formal command. It can operate by determining which problems receive sustained attention, which evidence is produced, which organisations survive, which pilot programmes become available for adoption, and which administrative capacities governments can afford. Where public institutions are under-resourced, the actor capable of supplying research, personnel, evaluation, and implementation support may acquire influence without ever issuing an order.
Formal governmental power is at least potentially exposed to mechanisms that do not normally reach private foundations. Public spending may require legislative appropriation; federal agency records are generally subject to disclosure requests under the Freedom of Information Act; and many federal rules require notice and an opportunity for public comment. These systems contain exceptions and do not guarantee effective accountability, but they create forms of visibility and contestability. FOIA, by contrast, does not apply to a private institution merely because its work affects public policy. U.S. House history of the appropriations power; Department of Justice FOIA guidance; Administrative Procedure Act rulemaking requirements.
Accountability Proportional to Influence
The answer is not to treat foundations as governments or to give elected officials control over charitable priorities. That would sacrifice the independence that permits philanthropy to challenge official neglect and test unorthodox ideas. Nor should accountability become a political litmus test under which only popular causes may receive support.
Accountability should instead make policy-facing power more legible and contestable. Large foundations could disclose policy-related grants in a standard form, including intermediaries, objectives, selection criteria, intended institutional effects, and relationships with public agencies. Evaluations—including adverse or inconclusive results—could be published independently of decisions to renew a programme. Foundations could disclose conflicts of interest and create meaningful participation for communities expected to bear the consequences of the policies being developed.
Public agencies have obligations as well. When they accept substantial private support, they should disclose the terms, conditions, performance measures, and expected duration of the arrangement. They should preserve their own capacity to evaluate alternatives rather than allowing a funder’s preferred model to become the default simply because it arrives financed. Programmes that migrate from philanthropic experiment to public responsibility should face public review before private priorities harden into public commitments.
This standard is not hostile to philanthropy. It takes philanthropy seriously as an institutional force. Small donations may express solidarity or generosity. Large, coordinated grantmaking can structure fields of knowledge and action. Once it does, the relevant measure of accountability is no longer the benevolence of the donor or the legality of each grant considered separately. It is the public influence of the institution as a whole.
Foundation power is the conversion of tax-advantaged private wealth into public influence through research, advocacy, demonstration, and institutional partnership. When private institutions can convert concentrated resources into public decision-making power, accountability should be calibrated to the influence they exercise—not merely to their legal classification or formal compliance. The question is not whether foundations should exist. It is whether power at their scale can remain answerable principally to donors, boards, tax rules, and reputation.
