Key Highlights
- Semiliquid funds expand access to private-market strategies, but the wrapper is not a secondary detail.
- The wrapper determines how liquidity is delivered, which investors can participate, and whether the portfolio and operating model can support the promise made to clients.
As client interest in private market investing continues to grow, advisors are facing a new challenge: determining which access vehicles are best suited to their clients' objectives, liquidity needs and investment horizons. As demand for private market exposure continues to expand beyond institutional investors, interval funds and tender offer funds have emerged as some of the fastest-growing vehicles for delivering access within a semiliquid framework. According to XA Investments, assets in these structures surpassed $300 billion for the first time during the first half of 2026, underscoring their increasing adoption across the wealth management landscape.
In this article, we focus on two of the most widely used semiliquid fund structures, interval funds and tender offer funds, to help advisors evaluate the considerations, trade-offs, and client fit of each approach.
Start with the liquidity of the assets, not the label
A well-designed fund structure is one that appropriately matches investor liquidity expectations with the liquidity profile of the underlying investment strategy. A predictable repurchase schedule can be more suited for underlying assets that generate income potential or can otherwise support regular liquidity. A repurchase model that affords the manager more flexibility in timing and sizing may be a better fit when the assets have longer expected holding periods, irregular realization schedules, or limited secondary-market liquidity.
Fund liquidity can come from available cash, incoming investor subscriptions, portfolio income, permitted borrowing, and, when necessary, the sale of underlying assets. If the wrapper promises more access than the portfolio can comfortably support, the manager may need to hold a larger liquidity reserve, slow capital deployment, or sell assets at an unfavorable time. The result can be cash drag, constrained portfolio construction, or a client experience that falls short of expectations.
Interval funds: predictable liquidity offers with portfolio constraints
Interval funds are registered closed-end funds that offer to repurchase a minimum percent of shares on a predefined schedule, commonly quarterly. For advisors, that scheduled process can make the liquidity conversation more concrete. It can also support broader distribution because the structure combines private-market exposure with regular valuation, regulatory oversight and a defined repurchase framework.
The trade-off is that predictable liquidity creates a portfolio-management obligation. Strategies built around shorter-duration, income-producing assets, such as private credit, may be better positioned to support scheduled repurchases. Strategies dominated by assets with uncertain exit timing may face a harder choice between holding more liquid investments and accepting greater liquidity-management risk.
Importantly, a scheduled repurchase offer should not be viewed as a guarantee that an investor will be able to redeem all requested shares in any given period. If repurchase requests exceed the amount offered by the fund, shares are generally repurchased on a pro rata basis, and investors may need to wait for future repurchase opportunities to access additional capital. As a result, advisors should view interval funds as offering periodic opportunities for liquidity rather than assured liquidity on demand, and align client expectations accordingly.
Tender offer funds: greater manager discretion, less investor certainty
Both interval funds and tender offer funds seek to balance investor access to private-market investments with the liquidity limitations inherent in the underlying assets. While both structures provide periodic opportunities for investors to access capital, neither offers daily liquidity, and neither guarantees that investors will be able to redeem all requested shares in a given period. The principal distinction is that interval funds conduct repurchase offers on a predetermined schedule with a minimum mandated repurchase amount, while tender offer funds generally provide managers with greater flexibility regarding the timing and size of repurchase offers.
Tender offer funds are also registered closed-end funds that can provide regular valuation, but liquidity is generally offered through board-approved tender offers rather than a fixed interval mechanism. Tender offer funds set out their intended repurchase schedule and amount in advance – often quarterly, at 5% or less per period – but managers have discretion in each period to repurchase fewer, or none, of the fund shares. That discretion can allow the fund’s liquidity program to reflect the assets’ realization cycle and current market conditions.
For less liquid strategies, including private equity, venture capital and real assets, this flexibility may better protect the portfolio from forced transactions. The client trade-off is less certainty about when shares can be tendered. For both interval funds and tender offer funds, advisors should frame the allocation as capital that may remain invested for an extended period, not as a substitute for daily-liquidity holdings.
A practical comparison for advisor diligence
| Decision factor | Interval fund | Tender offer fund |
|---|---|---|
| Liquidity mechanism | Scheduled repurchase offers of a minimum percent of shares at predefined intervals | Periodic tender offers generally subject to board approval, with manager flexibility to pause repurchases indefinitely |
| Potential strategy fit | Shorter-duration or income-producing private-market assets | Less liquid assets with longer or irregular realization cycles and limited expected income |
| Client expectation | More predictable opportunities to request liquidity | Less predictable liquidity access and potentially longer holding periods |
| Portfolio trade-off | May require a larger liquidity reserve and can create cash drag | Can preserve investment flexibility but more heavily restrict investor liquidity |
| Distribution consideration | Potentially compatible with broader retail and platform distribution | Often better suited to investors and channels comfortable with greater illiquidity |
Fees and eligibility can change the audience
Semiliquid funds combine complex assets with registered-fund governance, valuation, reporting and investor servicing. Those demands can result in fee structures that differ substantially from familiar mutual funds and exchange-traded funds. In some cases, performance-based fees may also affect investor eligibility and product availability. As a result, fee considerations are often best assessed alongside the broader structural and access features of the investment.
Advisors should ask who can invest, which fees apply, whether existing clients receive different economics in other vehicles, and how the structure affects the total client experience. A vehicle designed for broad distribution may require different fee choices than one intended for qualified or accredited investors.
The operating model is part of the investment proposition
A semiliquid vehicle adds recurring demands across valuation, cash management, reporting, transfer agency, custody, compliance and fund governance. These are not merely back-office questions. Weakness in any one area can affect transaction timing, returns, communications and confidence in the vehicle.
It’s important to understand how the manager will value less liquid holdings, manage subscriptions and repurchases, oversee service providers and maintain consistency between portfolio liquidity and the fund’s investor terms.
Five questions to ask before recommending a semiliquid fund
- What role should the allocation play in the client’s portfolio, and what capital can the client leave invested for an extended period?
- How does the liquidity of the underlying assets support the fund’s repurchase or tender-offer process?
- Is the client prepared for the possibility that full redemption may occur over time rather than in a single repurchase period?
- How do investor eligibility, fees, valuation frequency and platform requirements affect suitability and distribution?
- Does the manager’s operating model support valuation, cash management, reporting, governance and investor communication at the required scale?
The path forward
Interval and tender offer funds can both serve as bridges between daily-liquidity products and fully illiquid private funds. The right choice is not the vehicle with the most liquidity or the widest access. It is the vehicle whose liquidity terms, portfolio construction, and operating model fit together while meeting the investor’s risk, return, and liquidity needs.
For advisors, the practical takeaway is to treat structure as part of the investment thesis. Define the portfolio role first, then test whether the underlying assets, redemption design, fees, eligibility, and servicing model support that role. If those elements do not align, the wrapper can undermine the strategy it was meant to deliver.
