Pre-IPO Secondary Common Share Liquidity Discount
The Formal Definition
The substantial valuation discount (typically 25% to 50%) applied to private startup common shares sold on secondary platforms (such as Forge or EquityZen) relative to the company's last primary venture round, reflecting the lack of investor liquidation preferences, company transfer restrictions, and multi-year illiquidity horizons.
$$\text{Secondary Realized Price} = \text{Last Preferred Financing Round Price} \times (1 - \text{DLOM}) - \text{Transfer Surcharges}$$
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Holding pre-IPO stock options feels like holding millions in paper wealth until you actually try to sell them. Silicon Valley venture funds buy preferred shares with downside liquidation protection, but employees get common stock. On secondary desks, buyers hit employee common shares with a 30% to 50% discount to the last funding valuation. After the platform takes its 5% fee and the company drags its feet on approval, your paper net worth takes a massive haircut."

Examining the real numbers for: An early employee liquidating $500,000 worth of private startup common stock (based on the last Series D valuation round at $50.00/share)
| Execution Metric | Patient Public IPO Seller | Pre-IPO Secondary Seller |
|---|---|---|
| Fee / Rate | $0 commission | 5.0% platform transaction fee ($17,500) |
| Spread / Buffer | Waited until the company completed a public direct listing on Nasdaq; held shares through the 180-day lockup window | Sold private common shares via an unvetted secondary marketplace 18 months ahead of an expected public offering |
| Execution / Status | Sold 10,000 shares on a public lit exchange at the open market price of $52.00/share with tight 1-cent spreads | Buyers demanded a 30% common-vs-preferred illiquidity discount ($35.00/share vs. $50.00 preferred benchmark) |
| Total Cost / Result | Captured full market value through public listing liquidity | Surrendered 34% of headline equity value to access liquidity early |
How Brokers Weaponize This Term
Before selling private shares on secondary marketplaces, review your option exercise agreement for a 'Right of First Refusal' (ROFR) and 'Transfer Fee' clause. Many startups charge $2,500 to $5,000 in corporate legal fees to process secondary stock transfers, which can wipe out returns on smaller sales.

Why do common shares trade at a discount to preferred shares in private startups?
Because preferred shares carry 'Liquidation Preferences' that guarantee investors get their money back first in an acquisition or bankruptcy, while common shares can be wiped out to zero.
What is a company transfer restriction in private equity?
Private companies typically require explicit board approval for any secondary share transfer, and many startups ban employee sales entirely to prevent outside investors from entering their capitalization table.
