SpaceX's record-setting IPO opened one of the world's most valuable companies to public investors, but those investors do not get equal say in how it is run. Elon Musk holds just over 40% of the company's equity while controlling more than 80% of the vote, according to Bloomberg.
The structure is known as dual-class shares, where different classes of stock carry different voting rights. IPO adviser Lise Buyer says the arrangement can protect founders from short-term market pressure, allowing them to make long-range decisions without being pushed around by quarterly earnings demands. But the SpaceX structure goes well beyond what is typical, according to Harvard Law School professor Lucian Bebchuk, who warns it raises serious risks around accountability, succession, conflicts of interest, and shareholder value.
Some institutional investors have already decided the trade-off is not worth it. Danish pension fund AkademikerPension rejected the stock entirely, citing what it calls catastrophic governance. The fund's decision has drawn attention because it puts a name and a rationale to a concern that many investors may share but have not acted on publicly.
The SpaceX IPO is now functioning as a test case for a broader question facing public markets: how much control are investors willing to hand over to high-profile founders in exchange for access to their companies? The answer so far is not uniform. Some investors are buying in. Others are walking away.
The debate is not new. Dual-class structures have been used by tech companies for years, with Google and Meta among the prominent examples. But observers say the scale of Musk's voting control at SpaceX pushes the model further than most prior cases, and the company's profile makes the governance questions harder to ignore.
There is no pending regulatory action on dual-class structures at this time, and the SpaceX IPO has proceeded. But the conversation it has started about founder control and public accountability is likely to continue as more high-value private companies consider going public.
