Capital acquisition brokers: a focused model for private markets

Raising capital involves more than finding an interested investor. The intermediary’s permissions, the investor’s eligibility, and the transaction itself have to fit together. FINRA’s capital acquisition broker framework is a useful example of that discipline.

What is a CAB?

A capital acquisition broker is a FINRA member broker-dealer with a limited business model. Permitted work includes advising issuers and private funds on fundraising, helping prepare offering materials, providing valuation and structuring services, and acting as a placement agent in specified transactions. [1]

FINRA provides a tailored rule set for these firms. CABs cannot carry customer accounts, handle customer funds or securities, or conduct market-making and proprietary trading. The framework also excludes operating Regulation A or Regulation Crowdfunding offering platforms. CAB status remains a regulated firm category. [2]

What changed in March 2026?

FINRA’s Regulatory Notice 26-04 announced amendments effective March 25, 2026. Several changes stand out: [3]

• Buyer-side primary placements. CABs may represent institutional investor buyers in newly issued, unregistered securities transactions.
• Specified secondary transactions. CABs may act for institutional buyers or sellers when both sides are institutional investors and the resale qualifies for a Securities Act registration exemption.
• Broader M&A representation. CABs may represent buyers or sellers in qualifying private-company control transactions. Joint representation requires clear written disclosure and both parties’ written consent.
• Eligible employees. The institutional-investor definition now includes specified eligible employees; it does not cover every employee. Reg BI and Form CRS apply where their respective retail definitions are met.

Accredited does not automatically mean eligible

The CAB institutional-investor definition has its own criteria. It includes specified financial institutions, qualifying plans, persons with at least $50 million in total assets, qualified purchasers, and other defined categories. An investor’s accredited status alone does not establish that the investor meets this separate definition. [1] The 2026 notice adds the eligible-employee category described above. [3]

My perspective

I see these changes as a reason to be more precise in commercial discovery. Before discussing a fundraising or liquidity solution, I would want to understand who is being represented, whether the security is newly issued or being resold, and how each participant qualifies.

For example, a private-company shareholder seeking liquidity presents a different problem from a company raising fresh capital. My starting questions would be: Who owns the shares? Who is the intended buyer? What restrictions govern the transfer? Which regulated intermediary is equipped to support the transaction?

My takeaway is that strong business development begins with understanding the transaction. A larger network becomes more useful when the process can identify the right participants, surface constraints early, and bring the appropriate specialists into the conversation.
