24/7 Wall St. explains tax issues in Musk’s plan to give SpaceX shares to children

Musk’s post and the unanswered question

24/7 Wall St. reports that on October 19, 2026, Elon Musk posted on X that he would give one SpaceX share to every child in the United States next year. He said, “This will be the first of many.” The article notes that Musk did not say how the shares would be delivered, and says that missing detail affects nearly every tax outcome.

The piece says SpaceX closed at $144.75 per share on October 22, 2026. Using Yahoo Finance data cited by the article, there are about 73 million children under 18 in the U.S. At that price, one share for each child would total about $10.6 billion.

Direct gifts and the annual exclusion

24/7 Wall St. says federal gift tax begins with the annual exclusion in 26 U.S.C. § 2503(b)(1). The article states that the base figure is $10,000 per recipient, and that inflation adjustments put the 2026 amount at $19,000.

The report says the exclusion applies only to gifts of a present interest, meaning the recipient can use the gift right away. It says a $144.75 share given directly, usually through a custodial UTMA or UGMA account run by a parent, would fall below the 2026 exclusion amount. If a gift does not qualify for the exclusion, the article says it counts against the donor’s lifetime exemption, which it gives as $15,000,000 for 2026.

Trump Accounts and the limits the article says apply

The article says Yahoo Finance, citing a Bloomberg report, identified Trump Accounts as a possible vehicle. It says § 530A(d)(1) bars payments before the first day of the calendar year in which the child turns 18.

24/7 Wall St. says funds locked until age 18 look like future-interest gifts. It contrasts that with 529 plans, where Congress specifically treated contributions as present-interest gifts. The article says Section 530A does not include the same language, so the IRS issued Rev. Proc. 2026-25 to treat Trump Account contributions as present-interest gifts for the annual exclusion. It says that safe harbor covers only individual donors who meet its scope rules, and that it is unclear whether a gift on Musk’s scale would qualify.

The piece also says Trump Accounts can hold only low-cost mutual funds or ETFs that track a broad U.S. stock index before age 18. Because a single stock does not fit that rule, the article says a SpaceX share would apparently need to be converted before deposit.

Two possible routes for the shares

24/7 Wall St. lays out two ways Musk could route the gift. If he gives personally, the article says his contribution would count toward the $5,000 annual limit per child under § 530A(c)(2)(A). It says that limit applies to all contributions combined, including those from parents and grandparents.

If the shares go through a charity, the article says a “general funding contribution” would not count toward that cap. It says § 530A(f)(2) allows only governments, Indian tribal governments, and 501(c)(3) organizations to make such contributions, and that they must go to a defined group of children. The article says this route may also be the most tax-efficient way to transfer appreciated stock. It adds that SpaceX COO Gwynne Shotwell has pledged more than $320 million in SpaceX stock to fund Trump Accounts for more than 2 million children, according to Yahoo Finance.

What children would owe later

The article says the tax consequences for the child come later, when the share is sold or the account is withdrawn. Under § 1015(a), the recipient of a gift takes the donor’s cost basis, meaning the donor’s original purchase price. The report says Musk’s basis is not public, so if it is low, most of the sale price could be taxable gain. It says inherited shares work differently because their basis usually steps up to market value at death.

The article also says gains from a custodial account can fall under the kiddie tax, reported on Form 8615, which can tax a child’s investment income at the parents’ rate.

Inside a Trump Account, the article says the tax math changes again. It reports that qualified general contributions do not count as the child’s investment in the account, so charity-funded money has no tax-free portion and is taxed as ordinary income when withdrawn. It says a personal contribution from Musk would be nondeductible and would likely count as after-tax money, leaving only growth taxable.

What grandparents should watch

24/7 Wall St. closes with a short checklist for grandparents. It says the account type will determine the basis rules, access age, and tax rate. It says Musk’s personal contributions could affect the $5,000 annual cap, while each grandparent’s 2026 exclusion of $19,000 per grandchild remains separate. The article also says families should keep records showing the gift date and the donor’s basis, because the child will need them when the share is sold. It ends by saying readers should consult a CPA before changing their own giving plans.
