MacKenzie Scott has done something genuinely strange in large-scale philanthropy: she gives enormous sums quickly, publicly announces the totals, and attaches very few conditions. By early 2025, public tallies of her giving had passed $19 billion spread across more than 2,400 organizations — universities, food banks, legal aid groups, housing coalitions, and small community nonprofits that had never seen a seven-figure check. For founders and nonprofit operators, the interesting story isn't the wealth. It's the legal machinery underneath it, and what that machinery demands of the groups receiving the money.

Who She Is, Briefly

Scott is a novelist who signed the Giving Pledge in 2019, committing to give away the majority of her wealth. Her gifts arrive in batches, announced in short essays that name the recipients and explain her reasoning: trust-based giving, unrestricted dollars, and a stated preference for organizations led by people closest to the problem. In 2022 she launched Yield Giving, a site that publishes her gift lists and, later, a searchable database of recipients. In 2024 it ran an open call that turned her quiet process into something closer to a competition — a shift with real legal and operational consequences for anyone hoping to be on the list.

The Structure Behind the Checks

How the money legally moves matters, because different vehicles carry different rules.

Donor-advised funds, not a classic foundation

Public reporting indicates Scott's gifts have largely flowed through donor-advised funds (DAFs) and a lean philanthropic team rather than a large private foundation. That distinction is not cosmetic:

  • Private foundations must distribute roughly 5% of assets annually, pay an excise tax on net investment income, and file a public Form 990-PF that discloses grants and trustees. Self-dealing and excess business holding rules apply.
  • DAFs live inside a sponsoring public charity. There is no payout mandate, no excise tax, and no grant-by-grant public disclosure requirement. The donor recommends grants; the sponsor legally approves and pays them — which is why a DAF gift sometimes arrives with a sponsor's cover letter rather than a personal note.

The practical effect is speed and privacy. A foundation with a board calendar and a 5% payout formula cannot move $2 billion in eight months. A DAF plus a small advisory team can.

Yield Giving as the visible layer

Yield Giving functions as the public face: it aggregates the gift announcements, explains the criteria, and hosts the open call. It is not a grantmaking foundation you can apply to on a rolling basis — there is no LOI portal open on a Tuesday afternoon.

What Arrives in the Paperwork

Most recipients describe being contacted out of the blue. The grant itself is typically unrestricted — no budget, no reporting schedule, no logo requirements. That generosity does not erase compliance obligations.

Unrestricted does not mean unaccounted for

  • The money must still be used for charitable purposes consistent with the organization's exempt mission. Unrestricted means flexible, not exempt from the prohibition on private benefit.
  • Accounting rules (ASC 958) require the gift to be recognized as a contribution, and the board should document acceptance — a resolution or a gift acceptance policy covering large, unusual, or restricted gifts.
  • The amount appears in contributions on Form 990, Part VIII, and can ripple into Schedule A. A single eight-figure gift can dwarf an operating budget and make the next three years of financial statements look like a cliff.
  • Recipients should confirm the check clears from a legitimate sponsoring charity or fund, keep the grant letter, and check whether state charitable-solicitation registration rules are triggered (unsolicited grants usually are not solicitation, but state rules vary).

The Public Support Test Trap

This is the compliance issue that catches well-meaning boards off guard. Public charities classified under section 170(b)(1)(A)(vi) must pass a public support test measured over a rolling five-year period. Contributions from any one donor that exceed 2% of total support are excluded from the numerator — the public-support side of the fraction — even though they still count in the denominator.

A sudden multi-million-dollar gift from a single source can therefore lower your public support percentage rather than raise it. Organizations that fail the test risk reclassification as a private foundation, which brings the payout requirement, excise tax, and disclosure regime described above. If a large gift lands, talk to a CPA about the five-year math immediately, not at filing time.

The Open Call: A Legal Path In

The 2023–2024 Yield Giving open call, administered with Lever for Change, drew more than 6,300 applications. Eligibility centered on 501(c)(3) public charities with annual operating budgets in the low-seven-figure range, and applicants submitted financials, governance information, and outcome data. Peer review panels scored submissions; the top-rated groups were originally slated to receive $1 million each, and the pool was expanded so that 279 organizations received $2 million and 82 received $1 million — about $640 million total.

The takeaway for organizations: the application was not a pitch deck contest. It was a documentation exercise. Groups with clean audits, board minutes, current registrations, and measurable results had a structural advantage over groups with a great story and messy books.

A Legal Hygiene Checklist for Founders

  • Confirm 501(c)(3) status and good standing in your state of incorporation.
  • Adopt a written gift acceptance policy and a conflict-of-interest policy; both are Form 990, Part VI questions.
  • Keep board minutes for major decisions, including accepting large gifts and setting investment policy.
  • Separate restricted and unrestricted funds in the accounting system from day one.
  • Maintain reviewed or audited financials once revenue crosses roughly $1 million.
  • Document outcomes in a form a reviewer can verify, not just describe.

The Real Lesson

Scott's approach rewards organizations that were already built to absorb scale: incorporated properly, governed with minutes and policies, and honest about the numbers. The gift is unrestricted, but the readiness isn't optional. Build the legal structure before the wire transfer, and a surprise email becomes an opportunity instead of an audit.
