Brokers Persist in Private Markets

Brokers persist because private stock still trades like a relationship market, not a true exchange. The hard part is not only moving shares on a ledger, it is finding a willing buyer for a specific block, getting the company comfortable, and navigating restrictions, pricing, and timing. That leaves room for intermediaries who know the buyers, know the sellers, and can get a messy deal across the line, even as software takes over more of the workflow.

• Most private share sales still happen through emails, calls, and brokered one to one matching. Software platforms have improved settlement and issuer run tenders, but they have not replaced the broker driven market for ad hoc trades, especially outside formal company programs.

• The broker role is strongest in larger institutional blocks. In practice, a broker is the person with a live map of who might buy $5M to $20M of a company right now, at what price, and with what diligence expectations. That is closer to high yield bond trading or commercial real estate than a retail stock app.

• The winning platforms are likely to work with brokers, not try to erase them overnight. Carta has the cap table, transfer agent, and tender workflow. Broker oriented networks like Zanbato and data tools like Caplight sit upstream in sourcing and price formation. The market is getting digitized in layers, not flipped all at once.

Over the next few years, the market should split more cleanly between software that handles permissions, settlement, and compliance, and brokers who handle discovery and placement. As more trading data accumulates, weaker brokers get squeezed out, but the best ones become more embedded because they bring trust, access, and execution in a market that is still far from fully electronic.
