Musk’s SpaceX gift puts Trump Accounts’ stock rules to the test

Musk’s SpaceX gift puts Trump Accounts’ stock rules to the test
Donated SpaceX stock generally can’t be refused or sold for years, leaving advisors to explain concentration risk to families

Elon Musk’s promise to give a SpaceX share to every child in America could make him the largest donor yet to Trump Accounts. It could also put a concentrated stock position, one that parents can neither refuse nor sell, into tens of millions of children’s portfolios.

Musk, who is the CEO of SpaceX and Tesla, announced his philanthropic plan over the weekend via a post on his social media platform X.

“Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many,” he wrote in the October 19 post. He did not say how the shares would be delivered. He did thank Brad Gerstner, the Altimeter Capital founder who helped design the program, for “helping enable this,”

President Donald Trump touted the news on his own Truth Social platform, saying that Musk was “giving SpaceX Stock to millions of American children through TRUMP ACCOUNTS!”

The U.S. Census Bureau counted roughly 72 million children under 18. At SpaceX’s Oct. 16 closing price of $146.03, that puts the gift at approximately $10.5 billion. Musk held about 6.42 billion SpaceX shares as of June 2026.

For financial advisors, the delivery mechanism matters more than the dollar figure. Late last month, the Treasury Department issued temporary regulations that let donors place publicly traded stock into Trump Account, the Section 530A savings accounts for children created by the One Big Beautiful Bill Act in 2025.

What the Trump Accounts stock donation rules require

As noted by CNBC, recipient families cannot decline donated stock, and they generally cannot sell it until five years have passed or until the end of the calendar year in which the child turns 17, whichever comes first. Early sales are permitted only in narrow cases, such as certain corporate transactions or a delisting from a national exchange; a deteriorating balance sheet does not qualify. If gifted shares are sold too early, the trustee must buy back the same number and class of shares.

That structure reverses ordinary charitable practice, in which the receiving organization or trustee has the final say, according to Carolyn Schenck, an attorney at Caplin & Drysdale and a former national fraud counsel at the Internal Revenue Service. Under the Trump Account rules, it is “the donor that’s dictating the terms of the gift,” she told CNBC.

The regulations state the rationale directly: “Donors are attracted by the hope that a stock contribution with a five-year holding period may lead recipients and their families to feel that they have a stake in the fate of the corporation.”

The holding period also protects donors from a wave of selling that could depress the share price, said Jane Ditelberg, chief tax strategist at Northern Trust. “Certainly, for people who have highly concentrated wealth in a company, and the assets are sitting in their own personal pockets, this makes it a lot easier to give,” she told CNBC.

Why concentration risk lands on advisors’ desks

Apart from donated shares, Trump Account money may be invested only in low-cost index funds. Treasury’s initial approved lineup announced in July consists of five broad index ETFs from BlackRock, Vanguard and State Street. A single-company holding sitting beside an S&P 500 fund, particularly if the company operates in a sector the index is already overweighted toward, is the kind of position advisors usually spend their time diversifying away from.

“Giving families more choices and more ability to hold the assets that they think are best for them and their kids’ future ... would be a good thing,” said Adam Michel, director of tax policy studies at the Cato Institute. “But this is not really that, because you have no choice in the asset that is being deposited into your child’s account, and then you also have no ability to sell it for the five-year holding period.”

The presence of single-stock positions adds a new spin to the decision between using Trump Accounts as opposed to 529 plans and other custodial accounts, which only makes bringing in advisors more crucial. Industry groups, including the National Association of Insurance and Financial Advisors, have argued that advisors belong at the center of that work.

Clients with large single-stock positions may see the program as a new giving channel. Donating appreciated stock to charity generally lets donors claim a deduction and avoid capital gains tax. Still, the rules are temporary and may be revised after public comment.

Will in-kind contributions survive a legal challenge?

Treasury argues that donated stock is different from other investments because no account funds are used to buy it. Ditelberg said a court could still view a requirement to hold individual shares as an investment decision, an argument that may carry more weight after the Supreme Court's landmark 2024 decision to overturn Chevron deference.

“I can’t tell you how a court would rule, but I could say there’s room for a challenge here,” she said. She also noted that state law gives people the right to disclaim an asset, and it is unclear how the Trump Account rules would accommodate that right.

How other billionaires and companies are funding the accounts

If Musk follows through, he would be the second philanthropist to publicly pledge stock. In July, SpaceX President Gwynne Shotwell and her husband pledged one SpaceX share each to more than 2 million children, aimed at lower-income kids ages 11 to 17. Those shares have not yet been distributed.

Some market professionals are side-eyeing the SpaceX execs' recent turn toward altruism.

“It feels like a publicity stunt... Will it create positive public sentiment? Perhaps,” Robert Pavlik, senior portfolio manager at Dakota Wealth Management – who does not hold SpaceX in the portfolios he manages – told Reuters.

Michael and Susan Dell took a cash route instead, pledging $6.25 billion to deposit $250 into the accounts of 25 million children. As of Oct. 7, more than 10 million children had received the deposit, representing $2.6 billion. Michael Dell has defended the shift to stock gifts. “It’s kind of hard for me to believe that’s a bad thing, right?” he told Yahoo Finance.

Corporate support has grown alongside the individual pledges. Dell, Visa, Micron and Delta Air Lines have pledged matches or other funding. Asset managers including Franklin Templeton have pledged to match the $1,000 seed for employees’ children.

Musk’s approach also contrasts with another effort Anthropic announced over the weekend. The AI developer said it would commit 5% of its shares to a new public benefit fund. Musk responded that he recommends “giving the shares directly to the public.”
