The dual-class share structure outlined in SpaceX’s initial public offering (IPO) filing, which gives chief executive Elon Musk outsized control, has reignited one of Wall Street’s longest-running debates over corporate governance.

Such structures are not uncommon in the U.S., particularly among founder-led firms. However, they remain one of the most contentious issues among governance experts and investor groups.

Supporters argue that visionary founders should be shielded from short-term market pressures, allowing them to focus on long-term innovation. Critics, by contrast, say concentrating power in the hands of insiders reduces accountability and weakens shareholder rights.

For many investors, Musk’s track record and strong public following make these concerns appear secondary, provided the company continues to deliver returns. Others, however, question whether he can effectively divide his attention among multiple high-profile ventures.

What is a dual-class share structure?

Under this system, a company issues more than one class of shares, each carrying different voting rights.

Typically, one class provides enhanced voting power and is held by founders or insiders, while the other is available to the public and carries fewer voting rights.

In SpaceX’s case, Class B shares carry 10 votes per share, compared with one vote for each Class A share. Musk is expected to retain a majority of the Class B shares after the offering, giving him significant influence over corporate decisions.

Why do critics oppose it?

Critics argue that the principle of “one share, one vote” is fundamental to shareholder democracy.

They warn that structures granting unequal voting rights allow a small group of insiders to maintain control, even if they do not hold a proportional economic stake in the company.

The Council of Institutional Investors said such arrangements can entrench management and reduce responsiveness to changing market conditions, potentially leaving companies slow to adapt.

Do dual-class structures affect performance?

Research findings on performance are mixed.

A 2024 study published by the Harvard Law School Forum on Corporate Governance found that companies in the Russell 3000 index with dual- or multi-class share structures outperformed their single-class peers over five- and 10-year periods.

However, research from the European Corporate Governance Institute suggests this advantage may not last. It found that valuation premiums for dual-class firms tend to fade over time, with such companies often trading at a discount roughly seven to nine years after their IPOs.

Do investors still care about voting rights?

Some analysts believe investor attitudes have shifted.

“Most investors have thrown out the idea that voting rights are valuable anymore, which is unfortunate,” said Brian Jacobsen, chief economic strategist at Annex Wealth Management.

In founder-led companies such as SpaceX, investors may be willing to accept weaker voting rights in exchange for exposure to a high-growth business.

“Some investors may view that as a serious governance trade-off, while others may decide it is the price of access to one of the few companies with SpaceX’s scale and positioning,” said Lukas Muehlbauer, an analyst at IPOX.

Which companies use dual-class shares?

Several prominent firms operate with dual-class or multi-class share structures, including:

  1. Alphabet (Google’s parent company)
  2. Meta Platforms
  3. Palantir Technologies
  4. Strategy
  5. Berkshire Hathaway

These companies illustrate how the model has become firmly established among major technology and founder-led businesses, even as debate over its merits continues.
