Here is the part most people miss: with a Trump Account, the law already narrows your choices. While your child is a minor, the money can only sit in a low-cost, broad U.S. stock index fund, the kind that tracks something like the S&P 500 and charges an expense ratio of 0.10% or less. So the “best investment” is mostly picked for you. Your real job is to choose the lowest-fee qualifying index fund, leave it alone for 18 years, and add money if you can.
Key Takeaways
- Trump Accounts can only hold low-cost U.S. equity index funds while the child is a minor, with an expense ratio of 0.10% or less.
- You cannot pick individual stocks, bonds, international funds, or active strategies during the growth period.
- The smart move is the lowest-fee broad U.S. index fund (S&P 500 or total U.S. market), then leave it alone.
- Time does the heavy lifting. An 18-year horizon means small fee differences and staying invested matter more than fund picking.
- Returns are not guaranteed, and past performance does not guarantee future results.
What You Are Actually Allowed to Invest In
Trump Accounts are built to keep things simple and cheap on purpose. During the growth period, the law limits the account to mutual funds or ETFs that track an index made up primarily of U.S. companies (at least 90% U.S.), do not use leverage, and charge an expense ratio of 0.10% or less. In plain English, that means a broad U.S. stock index fund, similar to an S&P 500 or total U.S. market fund.
What you cannot do while your child is a minor: pick individual stocks, choose actively managed funds, add bonds, or go international. Those rules exist to keep costs low and discourage speculation, which is reasonable for money meant to sit untouched for almost two decades.
So What Is the “Best” Choice?
Since the menu is restricted to broad U.S. index funds, the decision comes down to two things you can actually control: keep fees as low as possible, and stay broadly diversified. A fund tracking the entire U.S. market or the S&P 500 at the lowest available expense ratio checks both boxes. The Treasury’s default option places the money in a diversified U.S. stock index fund, so even if you do nothing, the $1,000 is invested in line with these rules.
This is not the place to get clever. Over 18 years, the difference between a 0.03% and a 0.10% fee adds up, while trying to outguess the market is both not allowed here and historically hard to do. Boring and cheap wins.
If your provider offers more than one eligible fund, you may see both an S&P 500 fund and a total U.S. market fund. The practical difference is small. The S&P 500 holds about 500 large U.S. companies, while a total-market fund adds mid-size and small companies for slightly broader coverage. Either one is a reasonable, well-diversified choice, so do not agonize over it. Pick the one with the lower fee and move on.
The Real Power Move: Leave It Alone
The biggest factor in how much that $1,000 grows is time, not fund selection. A $1,000 contribution growing at 7% a year for 18 years reaches roughly $3,380 before any tax at withdrawal. Bump the return assumption or add yearly contributions and the number climbs a lot from there. The catch is that this only works if you do not touch it and do not panic-sell when markets drop, which they will at some point over 18 years.
Compound Interest Calculator
A quick note on return assumptions: historically, U.S. stocks have returned roughly 7% a year after inflation and about 10% before inflation, but those are long-run averages, not promises. Some years will be negative. The long time horizon is what smooths the ride. For a deeper look at different contribution scenarios, see our full Trump Account calculator guide.
Should You Add Your Own Contributions?
You can contribute up to $5,000 per year to a Trump Account (indexed for inflation), on top of the $1,000 government seed. Adding money is what turns a modest seed into a meaningful balance by age 18. That said, a Trump Account is not always the best home for extra savings. Because withdrawals are taxed as ordinary income later, a 529 plan can be more tax-friendly for education, and a custodial Roth IRA may suit a working teen. Weigh those before funneling everything into the Trump Account.

What to Avoid
- Chasing high-fee funds. Over 18 years, fees quietly eat returns. Pick the lowest expense ratio available.
- Trying to time the market or pick stocks. It is not allowed here, and it rarely beats just staying invested.
- Touching the money early. Early withdrawals get taxed and often penalized, and they cut the compounding short.
- Panic-selling in a downturn. An 18-year horizon is built to ride out crashes. Selling low locks in the loss.
Frequently Asked Questions
Can I buy individual stocks like Apple or Tesla in a Trump Account?
No. While the child is a minor, the account is limited to broad U.S. index funds. Individual stocks are not allowed.
Can I invest the money in bonds to make it safer?
No. During the growth period the account holds U.S. equity index funds only, not bonds. The long time horizon is meant to handle the extra stock-market risk.
What expense ratio should I look for?
The law caps eligible funds at 0.10% or less, so aim for the lowest available within that limit. Even small fee differences matter over 18 years.
What if I do nothing after the $1,000 arrives?
The money is placed in a diversified U.S. stock index fund by default, so it stays invested. The main thing is to avoid pulling it out early.
Is a Trump Account the best place for all my kid’s savings?
Not necessarily. A 529 can be more tax-efficient for education, and a custodial Roth IRA may fit a teen with earned income. Consider your goal before adding extra money here.
Bottom Line
With a Trump Account, the best investment is the simplest one: a low-fee, broad U.S. stock index fund, left alone for 18 years. The law restricts you to exactly that kind of fund, so focus on minimizing fees, adding contributions if it fits your goals, and not touching the money. Because everyone’s situation differs and returns are never guaranteed, consider talking to a financial advisor before making big decisions.
