Valuing an Illiquid Stake

The comparable-round-plus-discount method most secondary prices actually use.

There's no public exchange price for a private company's stock, so secondary buyers and sellers anchor to the most recent priced round and adjust with a discount (or, for in-demand companies, a premium) that reflects illiquidity, limited information rights, and time to the next liquidity event.

The typical discount range cited across this market runs roughly 10–30% below the last round, though the right number for any specific deal depends heavily on how sought-after the company is and how stale the last round's pricing has become.

How it works

  1. Start from the last priced round's per-share (or common-equivalent) price as the anchor — adjusted first for the 409A gap if you're valuing common stock specifically.
  2. Apply a discount reflecting illiquidity, the buyer's reduced information rights, and how long until a plausible next liquidity event.
  3. Adjust further for company-specific demand — a widely sought-after, soon-to-IPO name can trade at a premium to its last round rather than a discount.
  4. Cross-check against any recent comparable secondary trades in the same company, if the seller or platform can point to them.

Worked example

The last priced round implies a common-equivalent price of $2.00 per share. A buyer applies a 22% illiquidity and information-risk discount.

Last round anchor price
$2.00 / share
Discount at 10%
$1.80 / share
Discount at 22% (this buyer's offer)
$1.56 / share
Discount at 30%
$1.40 / share

Why it matters: A 20-percentage-point swing in the discount assumption moves the price by $0.40 per share on a $2.00 anchor — a large enough gap that "what discount is reasonable here" is usually the actual negotiation, not the anchor price itself.

Frequently asked questions

Who sets the discount — is there a standard formula?
No standard formula — it's negotiated between buyer and seller (or set by a marketplace's pricing process), informed by the factors above rather than a fixed industry rate.
Can I see actual recent trade prices for a specific company?
Some marketplaces publish aggregated pricing data for well-known private companies — see the marketplace directory, particularly platforms noted for data products.
Is this tax or legal advice?
No. This is independent educational content, not investment, tax, or legal advice — every figure in the worked example above is illustrative, not a real transaction. Confirm your specific situation with a qualified advisor before acting on it.
