At a Glance
Preferred stock carries a liquidation preference, most often 1x non-participating, which returns the original investment before common holders are paid.
Common stock carries basic ownership and voting rights with no preference.
Anti-dilution protection, conversion rights, and pro rata rights (the right to invest in future rounds) also separate preferred from common stock.
An SPV holds the shares and passes their economics through to its limited partners (LPs), but the security depends on the deal. SAFE holders receive preferred stock only when the SAFE converts, and many secondary buyers purchase common stock.
On Sydecar, preferred stock SPVs made up 41% of primary deals and 65% of primary dollars raised in the past 12 months.
What Is Common Stock and What Is Preferred Stock?
In venture-backed startups, preferred stock is the equity class investors receive in priced rounds, and common stock is the class founders and employees hold. Preferred stock adds a liquidation preference, which pays investors back before common holders in a sale, plus conversion rights and other protections. Many SPV investors hold neither at first: on Sydecar, 49% of primary SPVs in the past 12 months invested through SAFEs.
Feature | Preferred Stock | Common Stock |
|---|---|---|
Who holds it | Venture investors in priced rounds | Founders, employees, advisors |
Payout priority in a sale | Paid first, up to the liquidation preference | Paid after preferences |
Liquidation preference | Usually 1x the original investment | None |
Conversion | Can convert to common, often 1:1; converts automatically at a qualifying IPO | Cannot convert to preferred |
Anti-dilution protection | Usually broad-based weighted average | None |
Voting | Votes as if converted, plus class-specific approval rights | One vote per share |
Board seats | Often negotiated by lead investors | Usually elected by founders |
Dividends | Rarely paid; usually non-cumulative | Rarely paid |
Public markets use the same terms differently. There, preferred stock is an income product that pays a fixed dividend. In startups, preferred stock is a downside-protection instrument, and dividends almost never pay out.
Why Do Venture Investors Receive Preferred Stock?
Investors pay a higher price per share than founders did, so they negotiate protections that common stock lacks.
Downside protection. Liquidation preferences let investors recover capital before common holders when a company sells for less than expected.
Governance. Preferred holders often receive board seats and approval rights over new financings, sales, and changes to their shares.
Ownership maintenance. Anti-dilution provisions and pro rata rights help investors keep their percentage as the company raises more capital.
How Do Liquidation Preferences Work?
A liquidation preference sets how much preferred holders receive before common holders when a company sells or winds down. It is the largest economic difference between the two classes.
1x non-participating. The investor takes the greater of the original investment or its converted share of proceeds. This is the most common structure.
Participating preferred. The investor takes the original investment first, then also shares in the remaining proceeds. This raises investor returns and lowers founder and employee payouts.
Multiple preferences. A 2x preference returns twice the original investment before common holders receive anything.
Worked Example: $10 Million Invested for 20% Ownership
Exit value | 1x non-participating: investor | 1x non-participating: common | 1x participating: investor | 1x participating: common |
|---|---|---|---|---|
$8M | $8M | $0 | $8M | $0 |
$30M | $10M (takes preference) | $20M | $14M | $16M |
$100M | $20M (converts to common) | $80M | $28M | $72M |
This example assumes one preferred investor, one class of common, and no participation cap. At $100 million, the non-participating investor converts because 20% of proceeds exceeds the $10 million preference.
What Other Rights Come With Preferred Stock?
Beyond the liquidation preference, preferred stock carries five rights that shape control and ownership.
Voting. Preferred holders vote on an as-converted basis and often hold class votes that can block new share issuances or a sale.
Dividends. Startups rarely pay dividends. Most terms make them non-cumulative, so unpaid dividends do not add to the preference.
Conversion. Holders can convert preferred to common, typically 1:1. Conversion happens automatically at an IPO that meets a minimum size or price.
Anti-dilution. If the company later sells shares at a lower price, the conversion ratio adjusts. Broad-based weighted average adjusts proportionally, and full ratchet resets to the new lower price.
Pro rata rights. The right to buy into future rounds to maintain ownership. Companies often grant it only to "major investors" above a set check size.
What Stock Do SPV Investors Hold?
SPV investors in primary rounds held SAFEs more often than preferred stock, and secondary SPVs bought common stock more than any other security. Sydecar analyzed nearly 2,000 SPVs that wired capital over 12 months between 2025 and 2026.

How Do Preferred Terms Flow Through an SPV?
The SPV holds the security as a single shareholder, and its operating agreement passes the economics through to each LP in proportion to their contribution. What LPs receive depends on which security the SPV buys.
Preferred stock. LPs share in the liquidation preference, conversion rights, and anti-dilution protection the SPV negotiated or received from the lead investor.
SAFEs. The SPV holds a right to future equity with no preference or vote. The SAFE converts into preferred stock at the company's next priced round.
Common stock in secondaries. LPs have no liquidation preference and are paid after all preferred holders. Secondary prices for common stock reflect that position. Company transfer restrictions, such as a right of first refusal, can delay or block a purchase.
Pro rata and major investor rights. Companies often reserve these for investors above a set check size. Managers exercise pro rata by launching a follow-on SPV.

Frequently Asked Questions
Is Preferred Stock Better Than Common Stock for Investors?
In startups, preferred stock gives investors more protection because it pays out first in a sale. Common stock can still earn the same return in a large exit, because non-participating preferred converts to common when that pays more.
What Is a Liquidation Preference?
A liquidation preference is the amount preferred holders receive before common holders in a sale or wind-down. A 1x preference returns the original investment first, and a 2x preference returns twice the original investment.
What Is the Difference Between Participating and Non-Participating Preferred?
Non-participating preferred takes either its preference or its converted share, whichever is greater. Participating preferred takes its preference and then also shares in what remains.
Do SPV Investors Receive Preferred Stock?
Only when the SPV buys preferred stock. On Sydecar, 41% of primary SPVs in the past 12 months held preferred stock, and 49% held SAFEs that convert to preferred at a later priced round.
Why Do Secondary Buyers Purchase Common Stock?
Employees and early team members hold most of a startup's common stock, and they often sell it in a secondary transaction. On Sydecar, 46% of secondary SPVs bought common stock in the past 12 months.
What Happens to Preferred Stock at an IPO?
Preferred stock usually converts to common automatically when the company completes an IPO that meets a minimum size or share price.
Can Common Stock Convert to Preferred Stock?
No. Conversion runs one way, from preferred to common.
What Is Anti-Dilution Protection?
Anti-dilution protection adjusts the preferred conversion ratio when a company issues shares at a lower price than a prior round. Broad-based weighted average adjusts proportionally to the new shares issued, and full ratchet resets entirely to the new price.
