Common stock vs. preferred stock: why the same company's shares trade at different prices

Ask what a company's "share price" is and most people assume one number applies to the whole cap table. In reality, a company can have several share classes trading at meaningfully different per-share values at the exact same moment — because a share's price isn't just a claim on the company's total value, it's a claim on a specific position in the payout order.

Preferred stock's protection has a price

Preferred stock — the class investors typically receive in funding rounds — usually carries aliquidation preference, guaranteeing its holder gets a set return (often their original investment, sometimes a multiple of it) before common holders receive anything in an exit. That protection is valuable, especially in a lower or uncertain exit scenario, and buyers price it accordingly — preferred stock in the same company is usually worth more per share than common, all else equal.

Common stock is a leveraged bet on the upside

Common stock — typically held by founders and employees — sits last in thewaterfall, absorbing whatever is left after every preference is satisfied. In a strong exit, that structure can make common stock the better-performing asset per dollar invested, since it doesn't share the fixed preference amount with anyone. In a weak or mediocre exit, the same structure can leave common holders with very little, or nothing, even while preferred holders recover their investment in full.

Why the gap widens with each new funding round

Each new preferred round typically adds another layer to the waterfall, usually senior to (or at least alongside) the rounds before it. The more rounds a company has raised, the more preference capital sits ahead of common — meaning the common-to-preferred pricing gap tends to widen as a company matures and raises more capital, not narrow. This is a large part of why a company's409A valuation (which prices common) so often sits at a small fraction of its most recent preferred round price.

What this means for a secondary buyer

A buyer evaluating a secondary purchase needs to know exactly which share class is on offer, not just the company's headline valuation — the same dollar amount buys very different risk exposure depending on where in the waterfall that specific security sits.
