Interval funds and evergreen structures give advisory firms access to private markets without capital calls, K-1 tax reporting, or ten-year lockups. Both are continuously offered vehicles that repurchase a limited portion of their shares at set intervals, typically quarterly and at net asset value, trading unlimited liquidity for substantially lower operational friction.
For most of private markets’ history, access has been the price of admission. Traditional closed-end funds require multi-year capital commitments, unpredictable capital calls, ten-plus year lockups, complex K-1 tax reporting, and minimums that put allocations out of reach for all but the largest clients. For advisory firms building private markets into a repeatable, scalable part of the practice, that structure has represented a persistent operational obstacle, not merely an investment one.
Interval funds and evergreen structures were built to solve exactly this problem. They are not a workaround or a diminished version of private markets access — they are a structural response to real demand from the wealth channel, and the growth in that segment reflects it.
How large is the evergreen fund market?
U.S. evergreen fund assets reached $607 billion in the first quarter of 2026, according to Morningstar PitchBook’s Q1 2026 U.S. Evergreen Fund Landscape. Interval and tender offer funds, the registered and continuously offered subset of that universe, held $233 billion in net assets at the end of 2025, per XA Investments’ Q4 2025 Non-Listed Closed-End Fund Market Update. Acuity Analytics’ 2025 evergreen fund research puts typical minimums between $5,000 and $25,000 and projects roughly 20% annual growth in the category through 2029.
What is an interval fund?
An interval fund is a closed-end fund registered under the Investment Company Act of 1940 that, unlike a traditional closed-end fund, offers to repurchase a portion of its shares from investors at set intervals — typically quarterly — at net asset value. Repurchase offers are usually limited to a set percentage of outstanding shares, commonly in the 5–25% range, which means liquidity is real but bounded, not unlimited or on-demand.
Because interval funds are continuously offered rather than raised in a single closing, they can accept new subscriptions on an ongoing basis, giving advisory firms the ability to allocate client capital when it makes sense for the client rather than waiting for a fund’s next closing window.
What is an evergreen structure?
Evergreen is the broader category interval funds belong to. An evergreen (or perpetual-life) vehicle has no fixed termination date and is designed to recycle capital continuously — realized gains and income can be reinvested rather than automatically returned to investors, and the fund keeps raising and deploying capital indefinitely. The category includes interval funds, tender offer funds, non-traded business development companies, and non-traded REITs, each with its own subscription and redemption mechanics.
Evergreen fund vs. drawdown fund: what is the difference for an RIA?
A traditional drawdown fund has a defined investment period, harvest period, and wind-down, which requires the advisory firm to manage the client relationship around a fund’s lifecycle. An evergreen structure removes that constraint — the vehicle persists, and the advisory firm’s allocation decision becomes closer to a standard portfolio sizing decision than a one-time commitment. The practical differences show up in five places.
“The shift that matters for advisory firms is not that private markets became liquid. It is that they became serviceable inside a normal operating model.”
How liquid is an interval fund?
Periodic liquidity is not the same as daily liquidity, a distinction not always apparent to clients evaluating these vehicles. A quarterly repurchase offer can be prorated or, in stressed markets, curtailed if redemption requests exceed the fund’s stated repurchase limit. That is not a hypothetical concern.
It has been reported that repurchase requests at publicly registered non-traded BDCs reached 12.4% of net asset value in the second quarter of 2026, up from 10.4% in the first quarter and from roughly 1.5% of net asset value through most of 2024. In the first quarter of 2026, sector redemptions exceeded new fundraising for the first time on record. Interval funds saw the same pattern: the Cliffwater Corporate Lending Fund received first-quarter 2026 redemption requests representing just under 14% of net asset value and repurchased the 7% maximum its terms permit without amending the offer, prorating the balance, as reported by S&P Global Ratings on March 18, 2026.
The limits functioned as they were designed to. Funds prorated or capped excess requests rather than force-selling assets, and the Federal Reserve’s May 2026 Financial Stability Report described outflows from semi-liquid private credit vehicles as having moderately exceeded inflows while characterizing redemption requests as manageable. The distinction worth carrying into a client conversation is between requests and fills: headline percentages describe what investors asked for, while what was returned was bounded by the cap.
Net asset value pricing is also a different mechanism than market pricing. Redemptions are filled at NAV, calculated periodically, not at a market-clearing price discovered through trading — which is a feature for long-term holders and a genuine consideration for any client who might need capital on short notice.
When should an advisor use an evergreen fund instead of a drawdown fund?
Interval and evergreen structures are not a replacement for traditional drawdown funds in every case — some strategies and some return profiles are still best expressed through a closed-end structure with a defined life. But for advisory firms building a repeatable private markets offering across a broad client base, evergreen vehicles solve the specific operational and access problems that have kept private markets a bespoke, high-touch offering rather than a standard part of a model portfolio.
The same allocation logic applies to building a private markets sleeve into a broader portfolio construction framework. Evergreen structures make that sleeve considerably easier to implement and maintain at scale.
Questions worth asking before recommending any interval or evergreen fund
These are the questions to put to a manager during diligence, not questions a prospectus will answer on its own.
- What is the stated repurchase limit, and has the fund ever gated or prorated a repurchase offer?
- How is NAV calculated, how often, and by whom — internal valuation or independent third party?
- What percentage of the portfolio is currently liquid versus illiquid, and how does that shift in a stress scenario?
- What is the full fee load, including any distribution or servicing fees layered on top of management fees and carry?
- How does the manager handle a period where redemption requests exceed available liquidity?
