Understanding the Secondary Market for Private Shares

Article hero image

Key Takeaways

  • The secondary market for private shares generally refers to transactions where existing investors buy and sell previously issued shares of private companies rather than purchasing newly issued shares from the company.
  • These markets may provide investors with potential access to private companies and may offer liquidity opportunities for existing shareholders, although liquidity is not guaranteed.
  • Participation in the secondary market typically involves risks, including limited company disclosures, valuation uncertainty, regulatory requirements, and the possibility that shares may not be easily resold.

Unlike publicly traded stocks, private investments are illiquid, which may make it difficult for investors to sell their shares or exit their positions until the company undergoes an initial public offering (IPO), acquisition, or other liquidity events. This is where the secondary market may play a role.

Generally, the secondary market for private shares serves as a meeting point where companies may find new investors, and investors may access private businesses. For companies, it offers a way to facilitate transactions without issuing new shares. For investors, it may provide an opportunity to buy shares in private companies, though liquidity is not guaranteed.

This informational guide outlines the opportunities for buying and selling private shares, including how the market operates, its potential benefits, and the risks and challenges involved.

What Is the Secondary Market for Private Shares?

The secondary market is where previously issued securities are traded among investors. Unlike the primary market, where companies issue new shares directly to investors during an IPO, the secondary market facilitates transactions between investors. In the context of private shares, typically this market allows investors to buy and sell equity interests in private companies that are not publicly listed. Private shares may include equity from startups or established firms that have chosen to remain private.

Often, the secondary market plays a role in providing liquidity for these investments, enabling existing shareholders to sell their stakes while allowing new investors to enter at valuations that reflect market conditions. However, liquidity is not always available, and share prices are subject to fluctuations.

How the Secondary Market Works

Secondary market transactions may occur between buyers and sellers without direct involvement from the issuing company. However, some transactions may be subject to company approval, contractual transfer restrictions, or regulatory requirements. Pricing is often determined by supply and demand dynamics but may not reflect the company’s intrinsic value. Additionally, share transactions may be subject to legal, regulatory, and contractual limitations.

Common characteristics of the secondary market include:

  • Liquidity: The secondary market may provide investors with an avenue to buy or sell shares. However, liquidity is not assured, and selling shares may take time, particularly during market downturns.
  • Platforms: Several online platforms facilitate secondary market transactions, connecting buyers with sellers while ensuring compliance with regulatory requirements. Platforms like StartEngine provide investors with a marketplace to trade shares originally acquired through its platform.
  • Valuation: Share prices fluctuate based on investor demand, and there is no guarantee that secondary market pricing will reflect a company’s actual value. Monitoring company performance metrics and industry trends may help investors in assessing valuation.

Potential Benefits of the Secondary Market for Private Shares

Some of the potential considerations for participating in the secondary market include:

  • Access to Capital: Companies may enable existing investors to sell their stakes without issuing new shares, potentially reducing dilution.
  • Investment Diversification: Investors may gain exposure to private companies that are not available through public markets.
  • Potentially Shorter Holding Periods: Secondary market transactions may involve investments that are further along in their development, though holding periods vary based on market conditions.
  • Liquidity for Existing Shareholders: Shareholders may be able to sell their stakes, though liquidity depends on demand and market conditions.
  • Access to More Developed Companies: Investors may acquire shares in companies that are further along in their growth stages, though risks remain.

Risks and Challenges of Participating in the Secondary Market

Despite its potential advantages, the secondary market also presents certain risks and challenges:

  • Limited Information Disclosure: Private companies are not required to disclose as much information as publicly traded firms, which may create valuation challenges.
  • Market Volatility: Prices in the secondary market may fluctuate significantly, and investors may experience losses if demand decreases or company performance changes. There is no guarantee that an investor will be able to resell shares at a favorable price or at all.
  • Liquidity Constraints: During market downturns, finding buyers for private shares may be difficult, and investors may need to sell at a discount.
  • Regulatory Compliance: Secondary market transactions must comply with various legal and regulatory frameworks, which may vary by jurisdiction.  

How to Buy Private Shares on the Secondary Market

If you are considering buying private shares through the secondary market, follow these steps:

  • Choose a Platform: Select an online platform or marketplace that is registered, if required, and complies with applicable regulatory requirements for secondary transactions. Verify its reputation, legal compliance, and suitability for your investment profile.
  • Verify Eligibility: Some platforms require investors to be accredited and may impose Know Your Customer (KYC) verification.
  • Research and Evaluate Opportunities: Conduct thorough due diligence on the company’s financial performance and growth potential.

Execute the Purchase: Follow the platform’s transaction process, ensuring all terms and conditions are reviewed before finalizing the transaction.

How to Sell Private Company Shares on the Secondary Market

If you are looking to sell private shares, consider the following steps:

  • Determine Eligibility: Verify whether your shares are eligible for resale. Some shares may be subject to holding periods or other restrictions.
  • Set a Valuation: Understand that valuation in the secondary market may be subjective and negotiated between buyers and sellers. Prices may not reflect the actual or fair market value of the company and could be influenced by limited liquidity and other market factors.
  • Close the Transaction: Complete the necessary documentation and consider compliance with all applicable regulations.

Who May Participate in the Secondary Market?

Several types of investors may engage in secondary market transactions, including:

  • Retail Investors: Individuals investing for personal accounts.
  • Accredited Investors: Individuals or entities that meet financial criteria set by regulatory authorities, such as the SEC, which may be required for participation in certain transactions.
  • Institutional Investors: Organizations such as private equity firms and hedge funds.

Common Trends in the Secondary Market

Several trends are shaping the secondary market, including:

  • Increased Liquidity Demand: Some institutional investors use the secondary market to rebalance portfolios.
  • Digital Marketplaces and AI Integration: Online platforms are expanding access, and AI is being used for market analysis.
  • Growth of Equity Crowdfunding: More companies are using equity crowdfunding as an alternative to venture capital.

Conclusion

The secondary market for private shares may provide certain investors with an opportunity to buy and sell equity in private companies, but participation carries inherent risks. These include limited liquidity, valuation uncertainty, transfer restrictions, and compliance with regulatory requirements. Investors should carefully assess their investment objectives, conduct thorough due diligence, and seek professional advice before engaging in secondary market transactions. While the market may provide flexibility in managing investments, it is important to recognize that private securities remain speculative and may not always align with individual risk tolerance or financial goals.

It should only be considered a long-term investment. You must be prepared to withstand a total loss of your investment.

Each investment also carries its own specific risks, and you should complete your own independent due diligence regarding the investment. This includes obtaining additional information about the company, opinions, financial projections, and legal or other investment advice. Accordingly, investing in private company securities is appropriate only for those investors who can tolerate a high degree of risk and do not require a liquid investment.

StartEngine Marketplace (“SE Marketplace”) is a website operated by StartEngine Primary, LLC (“SE Primary”), a broker-dealer that is registered with the SEC and a member of FINRA and the SIPC.

StartEngine Secondary (“SE Secondary”) is our investor trading platform. SE Secondary is an SEC-registered Alternative Trading System (“ATS”) operated by SE Primary that matches orders for buyers and sellers of securities. It allows investors to trade shares purchased through Regulation A+, Regulation Crowdfunding, or Regulation D for companies who have engaged StartEngine Secure LLC as their transfer agent. The term “Rapid,” when used in relation to transactions on SE Marketplace, specifically refers to transactions that are facilitated on SE Secondary, This is because, unlike with trades on the StartEngine Bulletin Board (“SE BB”), trades on SE Secondary are executed the moment that they are matched.

StartEngine Bulletin Board (“SE BB”) is a bulletin board platform on which users can indicate to each other their interest to buy or sell shares of private companies that previously executed Reg CF or Reg A offerings not necessarily through SE Primary. As a bulletin board platform, SE BB provides a venue for investors to access information about such private company offerings and connect with potential sellers. All investment opportunities on SE BB are based on indicated interest from sellers and will need to be confirmed. Even if parties express mutual interest to enter into a trade on SE BB, a trade will not immediately result because execution is subject to additional contingencies, including among others, effecting of the transfer of the shares from the potential seller to the potential buyer by the issuer and/or transfer agent. SE BB is distinct and separate from SE Secondary. SE Secondary facilitates the trading of securities by matching orders between buyers and sellers and facilitating executions of trades on the platform. By contrast, under SE BB, SE Primary assists with the facilitation of a potential resulting trade off platform including, by among other things, approaching the issuer and other necessary parties in relation to the potential transaction. The term “Extended”, when used in relation to transactions on SE Marketplace denotes that these transactions are conducted via SE BB, and that these transactions may involve longer processing times compared to SE Secondary for the above-stated reasons.

Even if a security is qualified to be displayed on SE Marketplace, there is no guarantee an active trading market for the securities will ever develop, or if developed, be maintained. You should assume that you may not be able to liquidate your investment for some time or be able to pledge these shares as collateral.

The availability of company information does not indicate that the company has endorsed, supports, or otherwise participates with StartEngine. It also does not constitute an endorsement, solicitation or recommendation by StartEngine. StartEngine does not (1) make any recommendations or otherwise advise on the merits or advisability of a particular investment or transaction, (2) assist in the determination of the fair value of any security or investment, or (3) provide legal, tax, or transactional advisory services.
