Issuer Controlled Private Share Liquidity
Carta and the future of liquidity
The core prize in private stock liquidity is not the fee on one trade, it is control of the workflow that makes trades possible. This market looks inefficient because pricing is opaque, approvals are manual, tax and transfer rules are messy, and buyers and sellers often find each other through brokers. New entrants naturally chase commissions on single deals, but the deeper opportunity is to become the trusted system that issuers use to run repeat programs at scale.

Most private share sales still happen through fragmented brokered processes, with cold outreach, transfer approvals, legal review, and buyer matching done by hand. That makes the market feel wide open to new brokers, but also makes it hard to build durable software unless the company itself cooperates.

Carta approached the market from the cap table outward. Because it already stores who owns what, grant history, holding periods, and 409A data, it can simplify tender offers, tax handling, identity checks, and transfers. That is a very different business from just matching a buyer and seller for a commission.
-
Competitors split along constituency lines. Forge and EquityZen built more marketplace style businesses around matching investors and sellers, while Carta and Nasdaq Private Market pushed more issuer-centric programs. That divide explains why so many entrants appear, each sees a broken slice of the process and attacks that slice first.
The market is heading toward fewer pure brokers and more full-stack infrastructure around issuer approved liquidity. The winners will be the platforms that turn private share sales from occasional bespoke deals into repeatable company run events, with pricing data, compliance, and employee workflows built into the same system.
