The Musk Foundation and the hole in charity tax design

What this is about

This review covers the Economist’s Business article “Elon Musk Foundation model” (October 17th 2026, p.57), together with the Back Story film review on the same subject (p.79). It is a piece of investigative reporting that reconstructs, from tax filings, how one of the world’s richest men actually runs his charitable foundation. The author is unnamed.

Key points

Elon Musk once called philanthropy “bullshit,” yet he runs America’s fifth-largest charitable private foundation. The Musk Foundation held $14.7bn in assets at the last count—a hair smaller than the Ford Foundation and more than double the size of the Rockefeller Foundation. But its website carries a mere 33 words, and it is run by a team of just three: Mr Musk, his family-office head Jared Birchall, and another employee, Matilda Simon.

Scouring filings from July 2020 to the end of 2024, the article traces the motives behind the giving. The biggest gifts—a total of around $8bn in Tesla stock—came in 2021 and 2022, the years when he came into billions of dollars of shares and faced a huge tax bill. Brian Mittendorf, an accounting expert at Ohio State University, says donors enjoy a “double benefit”: they avoid capital-gains tax on shares that originally cost little, then claim a charitable deduction based on the far higher market value.

The scale is confirmed by the books. At the end of 2024 the book value of the foundation’s stock was about $5.7m, against an estimated market value of $14bn. Under American law, grant-making foundations must distribute roughly 5% of their investment assets each year or face penalties, and the article judges the foundation “painfully slow” to do so.

The same issue also carries a film review. Alex Gibney’s documentary “Musk,” out in American cinemas and screened at the BFI London Film Festival, runs almost four hours, and its most notable absence is Mr Musk himself, who declined to be interviewed. The review’s verdict—that the film wavers between painting him as a reckless fanatic and as a grifter—does not settle the question the Business article raises. Neither portrayal explains the tax machinery around his foundation.

What bothered me

I see the heart of this article not as a story about one man’s stinginess or hypocrisy, but as a hole in institutional design. Donate shares that hold unrealised gains and you dodge capital-gains tax while claiming a deduction at market value. That mechanism is open not only to Mr Musk but to every wealthy person. Debating personal virtue will not close it. What needs fixing is the tax system itself.

The article hammers the foundation’s opacity, and I would go a step further: the opacity is built into the rules. A 33-word website and a three-person operation are possible only because nothing requires disclosure. That tax returns are the only public record effectively grants an exemption from accountability. I will say it plainly: this is not a failure of charity but a failure of a system without monitoring or disclosure.

Still, I cannot accept a reading aimed only at Mr Musk. The “double benefit” the article describes follows inevitably from how ordinary charitable deductions are designed. The problem is not that one particular person behaves badly; it is that a system allowing deductions at market value privileges gains that have not yet been realised. Change nothing about that and the next billionaire walks through the same gap.

What it means for the world

This is a universal lesson in tax design, not an American peculiarity. Anywhere a tax code lets a donor give appreciated assets and deduct their market value, the same gap exists. The question for every country is whether its deduction corresponds to a donation actually made, or to paper gains that were never taxed. Where the two diverge, the public purse quietly subsidises the avoidance of tax on unrealised wealth.

The second universal point is disclosure. Philanthropy that enjoys public subsidy—through foregone tax—owes the public an account of what it does. When the only public record is a tax filing, the boundary between charity and tax planning blurs. Strengthening non-profit transparency is not a technical detail; it is what keeps the tax preference tethered to genuine public benefit rather than to the quiet accumulation of untaxed wealth.

Who should read this

Anyone working on tax policy or the rules governing the non-profit sector should read it. It is also worth the time of general readers who tend to consume large donations as feel-good stories, and could stand to see the tax logic underneath.

Quotations

“They avoid paying capital-gains tax on the shares… and can then claim a charitable deduction based on the (far higher) market value.”
