SpaceX Wants Dual-Class Shares — Every Tech IPO That Tried It and What Happened

SpaceX is heading for an IPO. And if history is any guide, Elon Musk will keep the keys to the kingdom.

The company is expected to go public with a dual-class share structure — the same arrangement that lets founders control public companies while owning a fraction of the equity. Musk currently holds roughly 54% of SpaceX equity and controls an estimated 78% of voting power. At a rumored $150 billion-plus valuation, that is a lot of control in one pair of hands.

Dual-class shares are not new. They are standard operating procedure for big tech IPOs. But the outcomes for minority shareholders — the regular investors buying in on listing day — vary wildly. Some got rich. Others got locked out of every meaningful decision while watching their stock crater.

We mapped every major tech IPO that used dual-class shares and tracked what happened next.

How Dual-Class Shares Work

The mechanics are simple. The company issues two classes of stock. Class A shares go to the public, usually with one vote per share. Class B shares go to founders and insiders, typically carrying 10 or 20 votes per share. In Snap’s case, public shareholders got zero votes.

The result: founders can own 15% of the company but control 60% of votes. Public shareholders provide capital. Founders keep power. That is the deal.

The Scorecard: 13 Tech IPOs With Dual-Class Shares

Three winners. Ten losers. The pattern is stark.

DropThe Data: Of 13 major dual-class tech IPOs tracked by DropThe, only 3 (23%) have delivered positive returns to public shareholders. The average stock decline across the 10 losers is 50%. Dual-class tech stocks underperform single-class peers by 4-6% annually after five years, according to Institutional Shareholder Services.

The Winners Had Something the Losers Did Not

Google went public in 2004 with Larry Page and Sergey Brin holding 58% of voting power through 10:1 Class B shares. The stock is up 5,800%. Nobody is complaining about governance when the returns look like that.

Meta followed in 2012. Mark Zuckerberg locked in 60% voting control. Shareholders were furious after the Cambridge Analytica scandal. Multiple lawsuits called for ending the dual-class structure. But the stock has tripled since IPO. Money tends to quiet governance debates.

The connecting thread among the winners: massive revenue growth, expanding margins, and dominant market positions. When the business compounds, founder control looks visionary. When it does not, it looks like a trap.

The Worst Outcomes

Snap took dual-class to the extreme. Evan Spiegel and Bobby Murphy gave public shareholders zero votes. None. Class A stock came with no voting rights whatsoever. Spiegel and Murphy held 88% of voting power at IPO.

The stock is down 80% from its listing price. Shareholders have no mechanism to push for change. No board seats. No proxy fights. No say in strategy. They can sell or hold. That is the entire menu.

Rivian went public at a $66 billion valuation in November 2021. Down 85% since. DoorDash down 40%. Roblox down 50%. Coinbase down 60%. Unity down 60%. All dual-class. All with founders in control. All underwater.

The Sunset Question

Some companies build in an expiration date. Fitbit had a 7-year sunset clause on its dual-class structure when it went public in 2015. Zynga let its dual-class shares convert to single-class by 2018 after years of poor performance. Groupon dropped its structure by 2016.

Google introduced a limited sunset provision in 2019 — if a founder dies or transfers shares, voting power diminishes over time. But full removal has never happened.

Only about 10% of dual-class IPOs since 2015 include sunset provisions. Over 70% of institutional investors want them to be mandatory. The gap between what investors want and what founders offer remains wide.

What This Means for SpaceX

SpaceX is likely to go public with Musk holding super-voting shares at a 10:1 or 20:1 ratio. His current 78% voting control would carry over. At a $150 billion-plus valuation, that makes it one of the largest dual-class IPOs ever.

The track record says this: if SpaceX executes — if Starship works, if Starlink prints money, if the contracts keep flowing — nobody will care about governance. Tesla proved Musk can generate returns that make shareholders look past everything else.

But if the business stumbles, public shareholders will have the same experience as Snap investors. All of the downside risk. None of the decision-making power. The right to watch and wait while the founder calls every shot.

The Pattern

Twenty percent of U.S. IPOs between 2010 and 2020 used dual-class structures. More than 60% of those were tech companies. The trend is accelerating, not slowing.

Academic research from Harvard and Stanford consistently finds the same thing: dual-class firms trade at a 15-20% valuation discount after 5-10 years compared to single-class peers. The average annual underperformance is 3-5%.

The counter-argument writes itself. Google is worth $1.7 trillion. Meta rebuilt itself around AI while Zuckerberg held total control. Founder-led vision can work spectacularly when the founder is right.

But being right is the exception. The data says most dual-class IPOs leave minority shareholders worse off. The question for SpaceX investors is whether Musk is Google-level right, or Snap-level wrong.

History says the odds are against you. The upside, if it works, is that you do not get to complain.
