The private market wave is growing, and it appears workplace plan sponsors are increasingly eager to test the waters.

According to a new report from Cerulli Associates, 37% of plan sponsors are very interested in learning more about target-date funds or managed accounts that allocate to private markets. Interest is particularly higher among large plans that hold between $250 million and $1 billion in assets, where 57% of sponsors expressed strong interest.
Researchers suggested that larger plans may be first to adopt these investment options, given their greater sophistication and, in some cases, prior experience with private market assets.
On the other end of the spectrum, “micro” plans with less than $5 million in assets showed the least enthusiasm, with just 26% expressing strong interest in learning more about such investments.
Despite the general interest, the report notes that curiosity alone will not lead to an immediate wave of implementation.
“Interest does not equal immediate adoption,” Chris Bailey, director of Cerulli’s retirement practice, said in a statement. “Sponsors tell Cerulli they are concerned about fees and the risk of litigation over adding such investment options to their plan menus.”
The adoption gap in retirement plans
Despite the buzz, actual usage is expected to grow slowly. Asset managers and defined contribution (DC) consultants predict that in five years, only about 7% of plan sponsors will have adopted a target-date or managed account containing private market assets. By 2035, that figure is estimated to rise to between 15% and 20%.
A few core hurdles are preventing sponsors from moving forward, according to Cerulli research. Sponsors told Cerulli that litigation risks and the higher costs associated with private market investments weigh heavily on their lineup decisions.
Simple inertia could also be a roadblock to adoption. Sponsors are generally reluctant to change target-date managers, with fewer than 5% of plans making a switch in the past year, according to DC consultants in Cerulli’s study.
Advisors are ahead of the curve
While many sponsors hesitate, a majority of financial advisors appear ready to recommend these strategies. A Financial Planning survey of more than 200 advisors found that 51% of advisors believe private markets will become “somewhat more” or “much more” popular in 2026.
This tracks with data from market research firm Escalent, which found that roughly one in four DC plan advisors say they are likely to recommend alternatives in workplace plans, with 10% already doing so.
“We know from previous research that interest in alternative investments has been rising on the retail side,” Linda York, a senior vice president in Escalent’s Cogent Syndicated division, said in a statement. “These findings show that the same enthusiasm is starting to take hold within the DC plan space. Advisors have traditionally turned to alternatives as a diversification lever for high net worth and institutional clients. Now, these options are becoming more relevant for employees across all income levels.”
Target-date funds lead the private market adoption
Industry experts note that private markets will likely enter 401(k) plans through professionally managed solutions rather than as standalone investment options. In the report, Cerulli researchers predicted that target-date funds will be the first vehicle to achieve widespread adoption for private market allocations.
Using a target-date fund structure solves several operational problems. It allows asset managers to handle the liquidity and valuation complexities inherent in private assets, rather than passing those risks to the participant.
Hal Ratner, head of research for investment management at Morningstar, has shared a similar view, although his research has highlighted that the integration of private markets into target-date funds may have a smaller impact than many in the industry anticipate.
Ratner’s research found that while semi-liquid private market allocations can improve retirement outcomes, the boost to overall returns is “modest.”
“The main benefit of these vehicles may likely be a diversification benefit, which is important, as opposed to astronomical returns,” Ratner told Financial Planning. “And that should be factored into the equation.”
Work remains for plan sponsor PE adoption
For now, the story of private markets in 401(k) plans remains one of strong interest but limited action. Cerulli says asset managers can help narrow that gap by focusing on plan sponsor education and shifting investment discussions away from lowest-cost options and toward participant outcomes. Still, significant hurdles remain.
President Donald Trump’s executive order has triggered a review of ERISA fiduciary guidance that could expand access to alternatives, but the industry is waiting for greater clarity. Some sponsors say clear regulatory safe harbors are a prerequisite before adding such complex products.
Until the government spells out rules around liquidity, disclosures and ERISA standards, litigation concerns flagged by Cerulli are likely to keep many plan sponsors in a wait-and-see posture.
