The private markets have historically operated on a single structural model: raise capital, deploy it over a few years, return it at exit, repeat. That model is being challenged. Evergreen funds — also called open-end or perpetual capital vehicles — now represent one of the fastest-growing segments in private asset management, with Preqin estimating evergreen AUM crossing $350 billion globally by 2025. For GPs deciding how to structure a new fund and LPs evaluating where to allocate, the choice between evergreen and closed-end isn't just operational — it determines how capital compounds, how performance is measured, and who your investor base can be.

The Core Distinction

Closed-end funds raise a fixed pool of capital during a defined fundraising period, deploy it over an investment period (typically 3–5 years), and return capital to LPs as investments are exited. The fund has a finite life — usually 10 years, with optional extensions. Once the fundraising window closes, no new LPs can enter and no new capital can be added.

Evergreen funds have no fixed fundraising period and no defined end date. Capital is continuously accepted, investments are held indefinitely (or recycled into new deals), and LPs can typically enter or exit on a periodic basis — quarterly or annually — subject to notice periods and gates. The fund persists and grows rather than winding down.

These aren't just administrative differences. They produce fundamentally different investor experiences, performance metrics, operational requirements, and tax outcomes.

How Closed-End Funds Work

Closed-end funds are the classic private equity and venture capital structure. They follow a predictable lifecycle:

Fundraising period (Year 0–1): The GP markets the fund, conducts LP diligence, accepts commitments, and holds a final close. LPs commit capital but don't transfer it yet — they issue capital call commitments.

Investment period (Year 1–5): The GP identifies and executes investments, calling capital from LPs as deals are made. The fund typically deploys 80–90% of committed capital during this phase.

Harvesting period (Year 5–10): The GP works to exit investments — through IPOs, acquisitions, or secondary sales — and distributes proceeds back to LPs. The fund winds down as the portfolio is liquidated.

Extensions: Most LPA agreements allow 1–2 one-year extensions if the GP needs more time to achieve favorable exits.

Performance is measured using IRR (Internal Rate of Return) and TVPI (Total Value to Paid-In capital), both of which are sensitive to the timing of capital calls and distributions. A fund that calls capital late and exits early will show a higher IRR than one that deployed early even if the absolute returns are similar.

Who Closed-End Funds Work Best For

• Venture capital and growth equity: Concentrated bets in high-growth companies where exits are binary and take time

• Buyout strategies: Acquisition, value creation, and exit cycles that fit a 5–7 year window

• Real estate development: Project-specific capital with defined development and disposition timelines

• First-time fund managers: Institutional LPs often prefer closed-end structures because they're familiar, auditable, and have established governance frameworks

How Evergreen Funds Work

Evergreen funds operate more like a continuously managed portfolio than a sequence of capital events. Key structural features:

Continuous subscriptions: New LPs can join during defined subscription windows (quarterly or monthly). There's no "fundraising period" with a hard close — the fund grows as capital is accepted.

NAV-based pricing: LP interests are priced at Net Asset Value per unit or share, calculated periodically. New investors subscribe at current NAV; existing investors' interests are marked to market regularly.

Periodic liquidity: Most evergreen funds offer redemption windows — quarterly or semi-annual — subject to gates (caps on how much can be redeemed in any period) and notice periods (typically 90 days). This is semi-liquidity, not daily liquidity.

Capital recycling: Rather than distributing exit proceeds to LPs and winding down, evergreen funds typically reinvest proceeds into new opportunities — compounding capital within the vehicle rather than returning it.

No J-curve: Because capital is deployed continuously and isn't raised in one batch, the early negative returns that plague closed-end funds (the J-curve effect) are reduced or eliminated.

Who Evergreen Funds Work Best For

• Private credit and direct lending: Loan portfolios with rolling maturities that don't fit neatly into a 10-year fund life

• Infrastructure: Long-duration assets (utilities, toll roads, data centers) that generate stable cash flows indefinitely

• Real estate core/core-plus: Income-generating properties held for yield rather than value-creation and sale

• Wealth management channels: RIAs and broker-dealers servicing high-net-worth individuals prefer evergreen structures because they work within standard account management processes — no capital call commitments required from individual clients

• Experienced managers with sticky LP relationships: The continuous capital model rewards GPs who have established trust with their LP base

Side-by-Side Comparison

Performance Measurement: Why the Metrics Differ

This is where closed-end and evergreen funds diverge most sharply — and where comparisons across structures can mislead.

IRR is the standard closed-end metric. It measures the annualized rate of return accounting for the timing of cash flows in and out. A fund that calls $1M on Day 1 and returns $3M in Year 5 has a lower IRR than one that calls the same $1M in Year 3 and returns $3M in Year 5 — even though the absolute gain is identical. IRR rewards capital efficiency and penalizes early deployment.

NAV return is the standard evergreen metric. It measures the change in per-unit Net Asset Value over a period, similar to how a mutual fund is evaluated. It doesn't capture the timing advantage that IRR does, but it's more intuitive for periodic investors.

DPI (Distributions to Paid-In) matters for closed-end funds because LPs want to see realized returns, not just paper gains. An evergreen fund doesn't have a "distributions" concept in the same way — returns are embedded in NAV appreciation or dividend yield.

When comparing a closed-end venture fund to an evergreen private credit fund, you're not comparing like-for-like metrics. Be skeptical of any analysis that treats IRR and NAV return as equivalent measures.

Regulatory and Compliance Considerations in 2026

Both structures are subject to Regulation D exemptions for private placements, but evergreen funds operating in the wealth management channel increasingly operate as interval funds or tender offer funds under the Investment Company Act of 1940 — which subjects them to SEC registration, liquidity requirements, and concentration limits not applicable to traditional closed-end LP structures.

The SEC's 2024 amendments to the Private Fund Adviser Rules — several of which survived legal challenge in modified form — increased reporting and audit requirements for both structures. GPs managing funds exceeding $150M AUM must register as investment advisers and comply with Form PF reporting.

FinCEN's January 2026 AML/KYC rules apply equally to both structures. Any fund accepting new LP capital — whether at first close or through an evergreen subscription window — must implement Customer Due Diligence programs and verify beneficial ownership. Platforms like Allocations build this compliance infrastructure into the subscription process, so GPs aren't building KYC workflows from scratch each time a new LP enters.

The SEC's evolving guidance on digital asset fund classification (2025 token taxonomy framework) is also relevant for crypto-focused strategies considering evergreen structures — particularly around how NAV is calculated for illiquid digital assets.

Tax Treatment: What LPs Need to Know

Both closed-end and evergreen funds structured as partnerships issue Schedule K-1s to investors annually. K-1s can arrive late — March to April — which may require tax return extensions.

Key differences:

Closed-end funds generate K-1 income primarily at exit events. An LP may receive little to no K-1 income for the first several years (during the investment period), then significant capital gains income when the fund harvests.

Evergreen funds generate more continuous K-1 income — interest income from private credit portfolios, rental income from real estate holdings, or operating income from infrastructure assets. LPs should expect annual taxable income even without a formal distribution.

UBTI considerations for tax-exempt investors: Evergreen funds that use leverage (common in private credit) may generate Unrelated Business Taxable Income for pension funds and endowments. Closed-end VC and PE funds typically don't use leverage at the fund level, so this is less of a concern.

Carried interest: In both structures, the GP's carried interest is generally taxed at long-term capital gains rates if investments are held for more than three years — consistent with the current carried interest rules. The Biden-era proposals to change this treatment did not pass; carried interest taxation remains as-is through 2026.

Which Structure Should You Choose?

Choose a closed-end fund if:

• Your strategy involves concentrated, high-conviction bets with binary exits (venture, buyout)

• Your target LP base is institutional — pension funds, endowments, family offices — who are accustomed to capital call structures

• You're a first or second-time manager where a defined fund life provides LPs with a clear return-of-capital timeline

• Your investment horizon is naturally time-bound (development projects, turnaround situations)

Choose an evergreen fund if:

• Your strategy generates continuous income rather than episodic exits (private credit, infrastructure, core real estate)

• You want to access the wealth management channel — RIAs and broker-dealers — which require periodic liquidity and NAV-based pricing

• You have a stable LP base that trusts you with indefinite capital management

• You want to avoid the fundraising treadmill of raising a new fund every 3–5 years

• You're managing a strategy where capital recycling compounds returns better than distributing and re-raising

Consider a hybrid approach:

Some managers run both structures — a closed-end fund for opportunistic or high-conviction strategies and an evergreen sleeve for their income-generating or core portfolio. The operational complexity is higher, but the capital diversification and LP audience diversification can be worth it for managers at scale.

Where Allocations Fits In

Allocations supports both closed-end and evergreen fund structures, as well as the SPV layer that often feeds into both. GPs on the platform can:

• Launch a closed-end LP fund with defined commitment periods, capital call infrastructure, and K-1 administration

• Structure an evergreen vehicle with continuous subscription support and ongoing LP management

• Run SPVs alongside either fund structure — syndicating deal-by-deal access to LPs who aren't yet ready to commit to a full fund

The compliance infrastructure — KYC/AML under FinCEN's 2026 rules, subscription document management, cap table tracking — works across all three structures, so GPs aren't rebuilding their back office every time they add a new vehicle.

For emerging managers deciding between structures for the first time, Allocations' team works with GPs to match the right structure to their investor base, strategy, and operational capacity before launch.

Frequently Asked Questions

Can an evergreen fund have a carried interest structure? Yes. Most evergreen funds charge carried interest, but it's calculated differently — typically on realized gains above a preferred return or hurdle NAV level, assessed at redemption or on an annual crystallization basis rather than at fund close.

Are evergreen funds available to non-accredited investors? Some evergreen vehicles structured as interval funds under the Investment Company Act can accept non-accredited investors. Traditional partnership-structured evergreen funds require accredited investor status under Regulation D. Structure determines the eligible investor universe.

How do gates work in evergreen funds? A gate limits total redemptions in any given window — typically 5–25% of fund NAV per quarter. If redemption requests exceed the gate, they're processed pro-rata. This protects the fund from forced liquidation of illiquid assets to meet redemptions.

Can a GP convert a closed-end fund to evergreen? In theory, yes — but in practice it requires LPA amendments, LP consent, and a restructuring of the economic terms. Most GPs who want an evergreen structure launch it as a separate vehicle alongside their existing closed-end funds rather than converting.

What's the minimum to launch an evergreen fund? There's no legal minimum, but most evergreen structures become operationally viable at $20–50M AUM, where the administrative overhead (quarterly NAV calculation, LP portal, redemption processing) is justified by the fee base.
