Retirement savings hit record $48.1T as Americans keep investing

JAN 16, 2026

US retirement assets climbed to a historic peak of $48.1 trillion in the third quarter, marking another milestone in Americans’ long-term savings progress and reinforcing the central role retirement planning plays in household wealth.

New figures from the Investment Company Institute show total retirement holdings rising 4.5% from the prior quarter and representing roughly one-third of all US household financial assets. The latest increase reflects both market appreciation and steady contributions into workplace plans and individual retirement accounts.

IRAs remained the largest segment of the retirement market, ending the quarter with $18.9 trillion in assets, up 5.2% from the second quarter. Defined contribution plan assets, including 401(k)s and similar employer-sponsored plans, reached $13.9 trillion, a 5.1% quarterly gain. Government defined benefit plans held $9.5 trillion, rising 3.1% over the period.

The data also show how participants continue to rely on pooled investment vehicles inside employer plans. Mutual funds accounted for 58% of 401(k) holdings, with equity and hybrid funds representing the majority of those allocations. That trend reinforces the ongoing demand for diversified investment solutions and portfolio oversight within retirement accounts.

“The latest data show that retirement assets in the US are at a record high, underscoring the continued success of Americans' long-term retirement savings and investing,” said Shelly Antoniewicz, chief economist at ICI, pointing to the broader significance of the milestone.

She also noted that rising balances reflect expanding participation in retirement plans, even amid periodic market volatility, highlighting the durability of the defined contribution system and IRA framework.

Beyond asset totals, ICI reported that total US retirement entitlements which include financial assets, other retirement assets and unfunded defined benefit liabilities stood at $52.1 trillion as of Sept. 30. The figure illustrates both the scale of retirement wealth and the complexity of the system advisors navigate on behalf of clients.
