Private Market Investments: Definition, Access, Trade-Offs

What are private market investments?

Private market investments are ownership stakes or loans that are not traded on a public exchange, such as private equity, private credit, private real estate, and shares of companies before they go public (pre-IPO). They may offer different sources of return than public markets, but they are often illiquid, harder to value, more expensive, and limited to certain investors. Loss of capital is possible.

Talk through whether private market investments fit your situation

Private market access at LKL Advisors. LKL Advisors offers eligible clients the opportunity to invest in private equity, private credit, real estate funds, and pre-IPO companies, all in the same platform, with approval handled digitally in a few simple steps. Eligibility requirements apply, each offering has its own terms, and these investments are often illiquid and can lose value, including the entire amount invested.

Why this question comes up

People with high incomes, equity compensation, or a growing taxable account are often offered private deals before they have had a chance to learn how the category works. The terms used in those conversations, such as lock-up, capital call, and accredited investor, describe real limits on what you can do with your money.

This guide explains the vocabulary and the trade-offs in general terms. It does not name any fund, manager, provider, or product, and nothing here is a recommendation to buy, sell, or avoid any investment. If you are earlier in your planning, our financial order of operations guide describes where investing sits among other priorities.

1. What counts as a private market investment

Private market investments definition

A private market investment is an interest in a company, loan, or property that is not bought and sold on a public exchange. Because there is no exchange, the price is set by negotiation or by the manager's own valuation, and there may be no easy way to sell. The U.S. Department of Labor describes private market investments in a recent proposal as direct and indirect interests in equity, debt, or other financial instruments that are not traded on public exchanges (U.S. Department of Labor, fact sheet on the proposed rule on fiduciary duties in selecting designated investment alternatives, accessed November 3, 2026).

Four broad categories are commonly discussed. These are descriptions of how each works, not products:

• Private equity. Ownership stakes in operating companies that are not publicly traded. The SEC's investor education site says private equity funds often focus on long-term opportunities in assets that take time to sell, with an investment time horizon typically of 10 or more years (Investor.gov, Private Equity Funds, accessed November 3, 2026).
• Private credit. Loans made directly to companies by lenders outside the public bond markets. The borrower may be unable to repay, and the loan may be difficult to sell before it matures.
• Private real estate. Interests in properties or in loans secured by property that are held outside of public exchanges, including through real estate funds. Values depend on appraisals, and a sale may take time.
• Pre-IPO companies. Shares in a company before it makes an initial public offering. The SEC describes pre-IPO investing as buying a stake in a company before it offers shares to the public, and warns that the company may fail, may never go public, and that the shares may be difficult or impossible to resell (Investor.gov, Pre-IPO Investment Scams Investor Alert, accessed November 3, 2026). Information about the company may be limited, and a company expecting an IPO is not a promise that one will happen or that a market for the shares will develop.

Pre-IPO shares are one way these investments can overlap with equity compensation, because startup and tech employees may already hold shares or options in a private company. That is covered in section 4.

Potential benefit: these categories may behave differently from publicly traded stocks and bonds, which could add variety to a portfolio. Trade-offs: different does not mean safer. Returns are not guaranteed, you could lose some or all of the money invested, and the lack of a public price can make it harder to see how an investment is doing.

2. Who can access private market investments

Many private offerings are limited by law to accredited investors. The SEC says that individuals may qualify if they meet any one of several criteria. Financial criteria include a net worth over $1 million, excluding a primary residence (individually or with a spouse or partner), or income over $200,000 individually or $300,000 with a spouse or partner in each of the prior two years with a reasonable expectation of the same in the current year. Professional criteria include holding in good standing the Series 7, Series 65, or Series 82 license (SEC, Accredited Investors, last reviewed or updated April 24, 2026, accessed November 3, 2026). The full rule is Regulation D, Rule 501(a) (17 CFR 230.501, accessed November 3, 2026).

The SEC also notes that many offering exemptions limit participation to accredited investors or restrict participation by non-accredited investors. Meeting the definition makes you eligible. It does not mean an investment is suitable for you.

Some access routes are open to investors who are not accredited, usually through registered funds that have their own rules. For example, the SEC describes interval funds as closed-end funds that repurchase only a limited percentage of shares, generally 5% to 25%, at set intervals, often every three, six, or twelve months, and generally pro rata if requests exceed the amount offered (Investor.gov, Investor Bulletin: Interval Funds, September 25, 2020, accessed November 3, 2026). In August 2025, SEC staff said that when reviewing registration statements of registered closed-end funds that invest in private funds, it would no longer ask them to limit offers to accredited investors or to cap private fund investments at 15 percent of assets, so eligibility and minimums depend on each fund's own documents (SEC, ADI 2025-16, August 15, 2025, accessed November 3, 2026).

Potential benefit: a registered structure may widen access to private market exposure. Trade-offs: the wrapper does not make the underlying assets easy to sell. You may only be able to sell on a set schedule, you may not be able to sell everything you request, and the price you receive is set after you submit your request.

3. How they differ from public markets

• Liquidity and lock-ups. The SEC says an investment in a private equity fund is often illiquid, that it may be necessary to hold it for several years before any return is realized, and that funds typically limit investors' ability to withdraw (Investor.gov, Private Equity Funds, accessed November 3, 2026). You may not have access to the money for the full period.
• Valuation and transparency. The SEC notes that private equity funds themselves are not registered with the SEC and are not subject to regular public disclosure requirements (Investor.gov, Private Equity Funds, accessed November 3, 2026). Prices come from the manager or an appraisal, not from a market that trades every day.
• Fees and expenses. Offering documents and agreements should disclose and govern fees and expenses, and the SEC has brought enforcement actions involving fees and expenses that were not adequately consented to or disclosed (Investor.gov, Private Equity Funds, accessed November 3, 2026). Fees may be layered at the fund level, the manager level, and the platform level, and each one reduces what you keep.
• Minimums. The SEC says the initial investment amount for a private equity investment is often very high (Investor.gov, Private Equity Funds, accessed November 3, 2026). A large single commitment can concentrate risk.
• Capital calls. Some funds ask investors to commit a total amount and then send the money when the manager requests it, as set out in the fund's agreements. You may need cash available on short notice, and the terms of missing a call are in the documents.
• Tax reporting. Many private funds are structured as partnerships. The IRS explains that a partnership reports each partner's share of income, deductions, and credits on Schedule K-1, which the partner uses to prepare their own return, and that loss limitations tied to basis can apply (IRS, Partner's Instructions for Schedule K-1 (Form 1065), accessed November 3, 2026). That can add steps and cost to tax preparation.
• Conflicts of interest. The SEC notes that private equity firms often have interests that conflict with the funds they manage and that investors should be alert to them (Investor.gov, Private Equity Funds, accessed November 3, 2026).

Potential benefit: a long holding period may let a manager pursue strategies that need time. Trade-offs: you take on the cost of waiting, and you cannot readily sell if your circumstances change.

4. Where they may fit in a plan, and where they may not

Whether private market investments belong in a plan depends on what else is going on. In general terms, these situations may make an illiquid investment harder to justify:

• A concentrated employer stock position. If a large share of your net worth is already tied to one company, adding another hard-to-sell asset may increase concentration and reduce flexibility. Our equity compensation planning guide covers the main award types and their trade-offs.
• Private company shares you already hold. Startup and tech employees may already own stock or options that cannot be sold freely. Adding more illiquid assets, including pre-IPO shares of other companies, can compound the same limitation, and an IPO that does not happen, or that happens later than expected, leaves the shares locked in.
• A thin emergency fund. Money you may need within a few years generally does not suit an investment with a lock-up.
• No liquidity needs mapped out. Without a view of upcoming costs such as a home purchase, tuition, a career break, or an exercise cost and tax bill, it is difficult to judge how much illiquidity you can carry. Mapping every dollar of expected income and spending is a common first step.

Some people weigh a small allocation only after these needs are covered and they understand and accept the risks. Whether that applies to you depends on your own situation, and the basics usually come first.

5. Questions to ask before investing

• How long is the lock-up, and under what conditions, if any, could I withdraw early?
• What is the total of all fees and expenses at every level, and how are expenses allocated?
• How is the investment valued, how often, and by whom?
• Is there a capital call schedule, and what happens if I cannot meet a call?
• What tax forms will I receive, and when do they usually arrive?
• How large is this commitment compared with my total net worth and my liquid assets?
• What are the manager's conflicts of interest, and where are they disclosed?
• What is my plan if I need the money earlier than expected?

Pros and cons of private market investments

Potential benefits

• They may offer exposure to companies, loans, and properties that are not available on public exchanges, which could add variety to a portfolio.
• Returns may be driven by different factors than public markets, though that is not guaranteed and may not hold in every period.
• A long holding period may let a manager pursue strategies that need time to develop.
• Registered fund structures may open some access to investors who are not accredited.

Potential drawbacks and limits

• Illiquidity: you may be unable to sell for years, and in some structures only part of a request may be filled.
• Loss of capital is possible, including the loss of the entire amount invested.
• Valuations come from the manager or an appraisal and may change slowly or be revised.
• Layered fees and expenses reduce what you keep, and enforcement actions show that disclosure needs close reading.
• High minimums and capital calls can concentrate risk and strain cash flow.
• Partnership tax reporting adds complexity, cost, and potential delays.
• Eligibility rules, such as accredited investor status, limit who may invest, and meeting them does not make an investment suitable.

What to bring to a planning conversation

• A list of your current accounts, including taxable, retirement, and any private holdings
• Equity award documents, vesting schedules, and any private company shares or options you hold
• Your emergency fund balance and a list of expected large expenses over the next several years
• Any private investment offering documents you have received, including fee tables and lock-up terms
• Your most recent federal tax return, and any Schedule K-1 you have received
• Your income for the last two years and your expected income this year
• Your employer's retirement plan investment menu
• The questions you want to ask, including any from the list above

Frequently asked questions

What private market investments does LKL Advisors offer?

LKL Advisors offers eligible clients the opportunity to invest in private equity, private credit, real estate funds, and pre-IPO companies, all in the same platform, with approval handled digitally in a few simple steps. Eligibility requirements apply, and each investment has its own terms, fees, and risks. These investments are often illiquid, and you could lose some or all of the money invested.

What do private investments mean?

Private investments are interests in companies, loans, or property that are not traded on a public exchange. Because they do not trade publicly, they are often harder to sell and to value, and many are open only to investors who meet certain eligibility rules. Loss of capital is possible.

What is the dark side of private equity?

The SEC's investor education site points to several risks: private equity funds are often illiquid and may require holding for several years, they are not subject to regular public disclosure requirements, fees and expenses can be layered, and managers often face conflicts of interest. The SEC has brought enforcement actions involving inadequately disclosed fees, expenses, and conflicts (Investor.gov, Private Equity Funds, accessed November 3, 2026).

Can I hold private market investments in a 401(k)?

It depends on your employer's plan. The plan's fiduciaries choose the investment options on the menu, so availability varies. As of November 3, 2026, the Department of Labor describes a proposed regulation on how plan fiduciaries select investment options, including asset allocation funds that include alternative assets such as private market investments. It was published in the Federal Register on March 31, 2026, and the materials we reviewed describe it as a proposal, not a final rule (U.S. Department of Labor fact sheet, accessed November 3, 2026; Federal Register, March 31, 2026). Check your plan's current investment menu for what is offered.

Do I have to be an accredited investor to invest?

Not always. Many direct private offerings are limited to accredited investors, and the SEC lists the net worth, income, and license criteria on its Accredited Investors page. Some registered fund structures are open to other investors, but they have their own repurchase limits, fees, and risks described in each fund's prospectus.

Are private market investments liquid?

Generally not. Direct private funds often restrict withdrawals for years. Registered interval funds repurchase only a limited percentage of shares at set intervals, generally every three, six, or twelve months, and may repurchase a request only in part (Investor.gov, Investor Bulletin: Interval Funds, accessed November 3, 2026).

Why do private market investments create tax complexity?

Many private funds are partnerships, so you may receive a Schedule K-1 reporting your share of income, deductions, and credits, and loss limits tied to basis can apply (IRS, Partner's Instructions for Schedule K-1 (Form 1065), accessed November 3, 2026). That can add steps and cost to preparing your return.
