For fifty years the deal inside a 401(k) has been unglamorous and unusually honest: a price every day, your money back every day, and a fee printed on one line. Two federal agencies are in the process of changing all three, and the second of the two proposals is expected this month.
This is not a rumor. It is a rulemaking calendar.
In August 2025 an executive order directed the Department of Labor, in consultation with Treasury and the SEC, to review the guidance that has kept private assets out of participant-directed retirement plans. On March 30, 2026, the Department of Labor released a proposed rule creating a process-based safe harbor for plan fiduciaries who select a designated investment alternative holding private equity, private credit, or real assets. The comment period closed June 1. The SEC's companion proposal cleared White House review in early September 2026, with a notice of proposed rulemaking expected in October. It would amend the Investment Advisers Act of 1940 and the Investment Company Act of 1940 to allow retail exposure to private markets through registered funds and to widen the set of clients who can be charged performance fees.
Neither rule is final. Neither one forces anything into your plan. But the direction is settled enough that the question is no longer whether you will be offered this. It is what you will do when you are.
What Is Actually Different About These Assets
Three things, and none of them is "riskier." Risk is the easy part to talk about.
The price is an estimate. A public stock has a price because someone just traded it. A private fund has a valuation because someone appraised it, usually quarterly, often with a lag. Your quarterly statement will look smoother than reality, which feels reassuring and is not.
The liquidity is gated. Most vehicles built for this purpose are interval or tender-offer funds that repurchase a limited percentage of shares on a set schedule. Plan sleeves are typically capped as a percentage of the account for exactly this reason. In a bad quarter, the part of your portfolio you most want to leave alone is the part you can actually sell.
The fees are layered. A management fee and a performance allocation inside the underlying fund, a wrapper fee, and then whatever the plan's recordkeeper charges. The DOL's proposal lists fees as one of six factors a fiduciary must weigh, alongside performance, liquidity, valuation, benchmarks, and complexity. That list is a fair summary of what makes this hard.
Dev Is Four Years From Retiring
Dev owns a specialty contracting business in Suffolk. He is 58, has $2.1 million in the company 401(k), and plans to step back at 62. His plan's recordkeeper has started sending material about a target-date series with a private markets sleeve.
The number that matters for Dev is not the expected return on private equity. It is this: in his first five years of retirement, roughly 60 percent of his spending will come out of this account, because his brokerage account is small and he is deferring Social Security to 70.
If 15 percent of the 401(k) sits in something he cannot redeem on demand, then during a market drawdown his liquid 85 percent has to fund 100 percent of his withdrawals. That is the mechanic that turns a reasonable long-horizon allocation into a sequence-of-returns problem. The allocation did not fail. The withdrawal schedule met it at the wrong moment.
For a 34-year-old with thirty years of contributions ahead and no near-term withdrawals, the same sleeve is a genuinely different proposition.
Should I Opt In If My Plan Offers It?
The honest answer for most people is: possibly, as a small slice, and only after you can answer three questions in your own words.
What percentage of your withdrawals in the first five years after you stop working will come out of this specific account? If it is most of them, keep the illiquid portion small.
What are the redemption terms? Not "is it liquid," but how often the fund repurchases shares, what percentage it will repurchase, and what happens when more people ask than the cap allows.
What is the all-in cost, including the fees inside the underlying fund rather than just the sleeve's headline expense ratio?
If those answers are not available in plain language, that is itself an answer.
If You Sponsor the Plan, This Is a Different Article
Most of our business-owner clients in Hampton Roads are on the other side of this decision. They pick the menu.
The DOL's proposed safe harbor is process-based, which is precisely what it sounds like: it protects a documented, prudent selection process, not a good outcome. Fiduciaries who add a private assets option will be judged on whether they evaluated the six factors, selected an appropriate benchmark, and communicated the liquidity terms to participants in language a participant can use. Fiduciaries who add it because a recordkeeper suggested it will find that the safe harbor has a floor and they are standing under it.
Watch the comment period and the final rule before you move. Nothing about this requires a decision in 2026.
One Estate Planning Footnote Nobody Mentions
If a private fund position ends up inside an IRA and the owner dies, the beneficiary inherits an asset that is hard to value on a date-of-death basis, hard to divide among multiple beneficiaries, and subject to the SECURE Act's ten-year distribution window. An illiquid asset with a mandatory ten-year emptying schedule is an awkward pair.
That is not a reason to avoid these investments. It is a reason the decision should not be made in isolation from the beneficiary designations and the trust language, which is exactly the kind of coordination that tends not to happen when the investment sits with one firm and the estate plan sits with another.
We keep the wealth, tax, and legal work under one roof so that the person modeling your retirement withdrawals and the person drafting your beneficiary language are the same conversation. If your plan is about to offer this, or you sponsor a plan that is being pitched on it, let's talk. Schedule a consultation.
