Trump Accounts reshape stock ownership, boosting one ETF’s potential enormously
The new government-funded investment accounts for children funnel money into low-cost index ETFs, with State Street's SPYM sitting in the pole position as the mandatory default.
Starting July 4, 2026, every eligible American child under 18 gets a government-funded investment account seeded with $1,000. The catch: that money can only go into ultra-cheap index funds tracking US equities, and one particular ETF just landed the most enviable gig in asset management.
The State Street SPDR Portfolio S&P 500 ETF, ticker SPYM, has been designated as the mandatory default investment for all Trump Account contributions at launch. With an expense ratio of just 0.02%, it’s essentially free to own, which is exactly the point.
How Trump Accounts actually work
Created under the 2025 One Big Beautiful Bill Act as part of the Working Families Tax Cuts provisions, Trump Accounts are tax-deferred investment vehicles designed exclusively for US citizen children under 18. Each eligible child receives a $1,000 government seed contribution. Families can then add their own money on top, with contribution caps indexed to inflation so the limits grow over time.
During the account’s growth period, the only allowable investments are low-cost broad US equity index ETFs and mutual funds with expense ratios capped at 0.10%. SPYM starts as the sole initial option, though the Treasury has approved a handful of additional ETFs that will become available later: the iShares Core S&P 500 ETF (IVV), iShares Core S&P Total US Stock Market ETF (ITOT), Vanguard Total Stock Market ETF (VTI), and SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM).
When the account holder turns 18, the whole thing converts to traditional IRA rules. Until then, withdrawals are restricted.
Why SPYM is the biggest winner
Pre-launch estimates suggest up to 6 million accounts could be opened, each starting with that $1,000 seed. That’s $6 billion in potential initial government contributions alone, before a single family adds their own money. Over time, financial analysts are forecasting these accounts could aggregate tens to hundreds of billions in assets under management.
SPYM’s designation as the mandatory default means it will capture the lion’s share of initial inflows. For State Street, which has been locked in a brutal fee war with BlackRock and Vanguard for years, this is an enormous structural advantage baked into federal law.
What’s notably missing
For a program bearing the Trump name, one absence stands out: there are no cryptocurrency or digital asset options available within Trump Accounts. Every dollar flowing through this program goes into traditional US equity index products.
What this means for investors
The 0.10% expense ratio cap sends an unmistakable signal about what policymakers consider acceptable fees. For the ETF industry, the program validates the low-cost indexing model through direct government endorsement.
A future Treasury could approve additional default options, diluting SPYM’s advantage. Or a subsequent Congress could expand eligible investments to include crypto ETFs, real estate funds, or other asset classes that would fragment the flows currently concentrated in a handful of products. For now, State Street is sitting in a position that BlackRock and Vanguard would very much like to share, and the clock starts ticking on July 4.
