How much are your private shares really worth? A guide to private valuations

Last updated: March 27, 2025

This guide breaks down the essentials to help you navigate your equity’s worth. From the differences between public and private stocks to key valuation types and how to leverage them - whether you’re selling, exercising options, or planning ahead.

📈 Public Stocks vs. Private Stocks

What do companies like Amazon, Nvidia, and Meta have in common? They trade on the public stock market – meaning anyone, us included, can buy a piece (i.e., a share or a fraction of it) of them through a broker or a platform of choice.

The value of the company is determined by market forces, reflecting real-time supply and demand. Think of the trading floors in the movies with prices going up, down, red, and green.

These stocks are regarded as liquid, meaning they can be bought and sold with ease. These companies also face higher scrutiny, must comply with regulations, and are required to be transparent about their financial results.

On the other hand, companies like Stripe, Databricks, Revolut, Stubhub, and Chime remain private. Their shares are not available on the public stock market and are typically held by few key people, like founders, investors, and employees with equity compensation - most likely, just like you.

Private companies face fewer regulatory requirements, since they don’t offer shares to the general public. The nature of private stocks makes them less liquid, as not everyone can buy and sell them. Additionally, their value is harder to determine since there isn’t a public market setting the price.

Understanding the different valuations is key to making informed decisions about your shares.

#️⃣ Why Are There Multiple Prices for Private Stocks?

Without a trading price, the value of a private company's stock isn't straightforward. There are different approaches to determining the likely value of the stock.

Let's look at why these different valuation methods exist:

Investors would want to value the company based on what they paid in funding rounds. However, this price applies to preferred stock, which often has different rights and protections than common stock
Companies are required by the IRS to set internal valuations of common stock (409A) for tax and compensation purposes, and these need to be updated regularly
Funds and analysts might estimate the value of the company based on its industry comparisons

⌛ Why Timing Matters in Valuation

Valuations are not only different depending on how they are calculated, but also on when they were last updated – the time component is something you should take into account when making a decision.

For instance, a 409A valuation is required to be updated every 12 months at minimum, but may not reflect the most recent company performance. A preferred funding round completed many years ago may also be an outdated valuation.

How should you use this information in practice?

When evaluating your equity, timing helps you determine which valuation is most relevant for your situation. If you’re looking to exercise your options, understanding how your 409A compares with other prices and valuations can help you assess potential tax implications.

Ultimately, using the right valuation at the right time helps you assess your options with more context and make decisions that align with your financial goals.

⚡ Why You Should Care

By now you should be clear on why these valuations aren’t just numbers – they directly impact your equity decisions. In practice, different valuations might influence:

Stock option exercise – should you wait or exercise your options now?
Tender offer participation – is the price you are being offered fair?
IPO pricing – when your company goes public, its price is influenced by how investment banks assess market demand. This is often done in relation to private valuations.

Having more knowledge about the valuations will help you maximize the value of your equity.

❓ Understanding Private Company Valuations

To help you make sense and navigate the nitty gritty, below is a table with a breakdown of the different valuations and what they tell you about your equity:

Preferred Price

The price investors paid in the latest funding round. Set by venture capitalists and investors.

What’s it best for?	Pros	Cons
Understanding investor sentiment and future expectations.	➕ Shows what institutional investors think about the company	➖ Might be inflated compared with actual market value of common stock

409A Valuation

An independent valuation used for tax purposes. Set by third-party firms.

What’s it best for?	Pros	Cons
Understanding investor sentiment and future expectations.	➕ Shows what institutional investors think about the company	➖ Might be inflated compared with actual market value of common stock

Public Comps

A valuation based on similar public companies. Set by investors and analysts.

What’s it best for?	Pros	Cons
Benchmarking against competitors.	➕ Provides a reference based on established players in the market	➖ It’s hard to find exact matches for private companies on the public markets given they are usually pioneers

Fund Marks

The value that investment funds assign to their holdings. Set by investment firms.

Understanding how institutional investors value the company.	➕ Gives insights into how major investors value similar assets	➖ The valuation can vary depending on the fund

How do these valuations work together?

Until a company goes public, no single valuation will tell you the full story – as they are the byproduct of looking at the same thing through different lenses. Combining them can paint a better picture of your stock’s worth.
