Private vs. Public Markets: What Investors Should Know

Key Takeaways

• Public and private markets differ in terms of liquidity, access, transparency, and regulatory oversight, which may influence how investors approach capital allocation or fundraising decisions.
• Private market investments may offer higher growth potential in some cases but typically involve longer holding periods, higher risk, and reduced disclosure compared to public markets.
• The choice between private and public markets generally depends on an investor’s risk tolerance, time horizon, access eligibility, and overall investment objectives.

In the U.S., the stock market has a market capitalization of approximately $62.2 trillion as of 2025. Meanwhile, the private equity market, a segment of the private market, is estimated at $0.82 trillion, with projections suggesting it may reach $1.24 trillion by 2030.

This raises a consideration: If you are looking to invest or raise capital, “should you explore the scale and liquidity of public markets, or consider private markets, which may involve longer-term commitments and different risk-return dynamics?

In this informational guide, we will outline some general differences between private and public markets to help you assess which option may align with your investment approach.

Private Market Investments

Private market investments involve assets that are not publicly traded on exchanges like the NASDAQ or NYSE. This includes private equity investments, venture capital, real estate, private debt, and hedge funds.

How to Invest in the Private Market?

There are several ways to enter the private market, though access to certain investments may be restricted to accredited investors under SEC regulations.

1. Equity Crowdfunding

Equity crowdfunding allows businesses to raise capital by collecting smaller contributions from a broad investor base.
Platforms such as StartEngine may facilitate investments in startups and early-stage companies.

However, these investments carry significant risks, including illiquidity and potential loss of capital. Additionally, investing through equity crowdfunding platforms is subject to SEC regulations under Regulation Crowdfunding (Reg CF). Investors should review offering statements, consider associated risks, and, if needed, consult a financial professional before making any investment decisions.

2. Angel Investing

Angel investors provide capital in exchange for equity in early-stage startups, often taking on significant risks with the possibility of returns if the company succeeds.

These investors may also provide mentorship, industry connections, and strategic guidance to help startups grow. Since early-stage companies often lack established revenue streams, angel investments carry a high risk of loss, and returns are uncertain.

Public Market Investments

The public market involves buying and selling securities such as stocks, bonds, and exchange-traded funds (ETFs) on major stock exchanges.

Since public markets allow investments through brokerage accounts, they are generally more accessible than private markets. However, private market investments tend to be less liquid, meaning investors may need to hold their assets for extended periods.

How to Invest in the Public Market?

Investors may enter the public market through various strategies. Here are two common approaches:

1. Buying Individual Stocks

Investors may purchase shares of publicly traded companies such as Apple, Google, or Tesla through a brokerage account. 

Returns depend on company performance, market conditions, and overall economic trends. However, public stocks carry risks, and investors should conduct due diligence to evaluate potential risks before making investment decisions.

2. Investing in Exchange-Traded Funds (ETFs)

ETFs pool funds from multiple investors to create diversified portfolios of stocks, bonds, or other securities.

For example, the SPDR S&P 500 ETF Trust (SPY) tracks the S&P 500 index, offering exposure to a broad range of U.S. companies. While this diversification may help manage risk, ETF investments are still subject to market fluctuations and economic changes.

Private vs. Public Markets: Returns and Regulatory Considerations

Returns

Certain venture capital opportunities remain limited to accredited investors under SEC guidelines, which establish qualifications for participation. Investors should review accreditation standards and regulatory requirements before participating in private market investments.

Public market investments may offer more liquidity and transparency compared to private investments.

Historically, the S&P 500 has delivered an average annual return of approximately 10.13% since 1957, though inflation-adjusted returns have averaged around 6.37%.  These returns account for stock price appreciation and dividend payouts but are subject to market fluctuations and are based on past performance and do not guarantee future results.

Private investments may offer the potential for higher returns in some cases, but outcomes vary significantly based on the investment selection, economic conditions, and company performance. Additionally, private investments often carry higher risk, longer investment horizons, and less liquidity than public markets.Regulatory Environment

Public companies operate under strict regulatory frameworks, including requirements to disclose quarterly earnings and comply with SEC standards for transparency.

Private companies have fewer disclosure obligations and are subject to different SEC regulations. While this allows for more flexibility, it also means that investors may have access to less information when evaluating private investment opportunities.

Considerations for Investing in Private or Public Markets

Now that the risks and characteristics of private and public markets have been outlined, here are some considerations that may help investors navigate these options:

• Diversification: Investors may consider diversifying their portfolios across both markets to balance potential risks and opportunities.
• Due Diligence: Conducting thorough research on investment opportunities, industry trends, and regulatory requirements may help investors make informed decisions.
• Risk Tolerance: Investors should assess their ability to withstand potential losses, as private markets tend to have higher risks and longer investment horizons.
• Consulting Professionals: Engaging with financial professionals or utilizing resources on investment platforms may help investors better evaluate opportunities.
• Portfolio Monitoring: Periodic reviews may help investors ensure their asset allocation aligns with their evolving financial goals.

Conclusion

Private and public markets offer different investment opportunities, each with its own risks and potential benefits. Understanding these differences may help investors assess which market aligns with their investment approach.
