How Dual-Class Stock Structures Cement Founder Control — From SpaceX to Big Tech

SpaceX’s IPO paperwork and similar arrangements at major firms have reignited debate over the balance between founder authority and shareholder rights

By Sofia Navarro

The dual-class share arrangement disclosed in SpaceX’s IPO filing, which would give CEO Elon Musk outsized voting control, has refocused attention on a longstanding corporate governance dispute. Advocates say stronger founder control shields long-term strategy from short-term market pressures, while opponents argue it concentrates power and can weaken accountability. Empirical studies offer mixed results on long-term valuation impacts, and prominent investors differ on whether the trade-off is acceptable.

How Dual-Class Stock Structures Cement Founder Control — From SpaceX to Big Tech

Key Points

  • SpaceX’s IPO filing would give Elon Musk majority control of Class B shares, with Class B carrying 10 votes per share versus one vote for Class A, concentrating voting power in insiders.
  • Supporters argue dual-class structures shield founders from short-term market pressures and enable long-term strategic decision-making; critics contend they erode the principle of "one share, one vote" and can entrench management.
  • Research is mixed: a 2024 Harvard Law School Forum study found dual-class firms in the Russell 3000 outperformed single-class peers over five- and 10-year periods, while a European Corporate Governance Institute paper found any premium often disappears and may reverse about seven to nine years post-IPO.

The share-class design described in SpaceX’s IPO filing - a structure that would place disproportionate voting power in the hands of the company’s chief executive - has reopened a familiar corporate governance debate on Wall Street. While this type of share split is common among founder-led firms, it continues to draw intense criticism from governance advocates and generate divergent views among investors.

Under a dual-class system, a company issues two types of stock that differ in voting rights. One class is allocated higher votes per share and is normally retained by founders or insiders; the other carries fewer votes and is sold more widely to public investors. SpaceX’s filing specifies that its Class B shares carry 10 votes per share, while Class A shares carry a single vote apiece. After the planned share sale, Elon Musk would hold a majority of the Class B shares, giving him substantial influence over shareholder decisions.

Proponents of dual-class frameworks say they protect visionary founders from short-term market pressures and enable them to pursue long-horizon strategies without the constant threat of shareholder activism. Opponents counter that such arrangements undermine the principle of "one share, one vote" and can concentrate control in too few hands. The Council of Institutional Investors, a leading investor advocacy group, has criticized the model, saying: "Over time, this founder-knows-best approach can entrench management and blindside executives to a need for change in strategy."

The governance controversy around dual-class shares often comes down to how investors value voting rights and the credibility they place in a founder’s ability to run multiple ventures. For some investors, Elon Musk’s history of building companies and his wide public profile make the governance compromises acceptable, provided the company delivers returns. Others question whether Musk can give adequate attention and focus to several of his high-profile undertakings simultaneously.

Academic and policy research presents a mixed picture. A 2024 study published in the Harvard Law School Forum on Corporate Governance found that, on average, companies in the Russell 3000 index that use dual or multi-class share structures outperformed single-class peers over five- and 10-year horizons. By contrast, a separate paper from the European Corporate Governance Institute reported that any valuation premium for dual-class firms tends to fade over time, and that such companies often trade at a discount to single-class peers roughly seven to nine years after their IPOs.

Perceptions among investors also vary. "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 businesses built around prominent founders, market participants may be especially willing to accept limited voting power in exchange for exposure to a company they view as uniquely positioned or scaled. "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, IPOX research associate.

Dual or multiple share classes are not unique to SpaceX. Several publicly traded companies have maintained two or more classes of stock, including Google parent Alphabet, Meta Platforms, Palantir Technologies, Strategy and Berkshire Hathaway, among others. Each instance raises similar questions about the proper balance between founder control and shareholder rights, and about how that balance affects long-term corporate performance and accountability.


Summary: SpaceX’s proposed share structure highlights the broader debate over dual-class stocks. Backers say it enables long-term decision-making by founders, while critics warn it entrenches management and weakens accountability. Empirical studies on market performance of such firms are mixed, and investor sentiment about the trade-off varies.

Risks

  • Concentrated voting control can reduce accountability and make it harder for shareholders to change strategy, a governance risk that could affect corporate oversight in sectors with founder-led firms such as technology and aerospace.
  • The valuation premium associated with dual-class structures may diminish over time, creating potential long-term market risk for investors in firms that adopt such arrangements, impacting equity valuations in public markets.
  • Investor disagreement over the value of voting rights introduces uncertainty in demand for shares of companies with multi-class capital structures, particularly in sectors where high-profile founders oversee multiple businesses.
