Elon Musk Owns Nearly Half of SpaceX — but Controls Over 82% of the Vote. What That Means for SPCX Investors.

SpaceX (SPCX) has quickly become one of the world’s most valuable public companies, but investors buying its shares are not getting the same influence over the business that they would at most large corporations. Elon Musk owns a 48.4% economic stake in SpaceX, yet the company’s dual-class share structure gives him more than 82% of its voting power. In practical terms, that leaves SpaceX’s founder and CEO with overwhelming control over major corporate decisions.

For shareholders, that concentration of power cuts both ways. Musk has made clear that he wants SpaceX to remain focused on long-term projects, from expanding Starlink and scaling its AI business to pursuing ambitions on the Moon and Mars. Having such extensive voting control gives him the freedom to make enormous long-term investments without worrying that shareholders dissatisfied with near-term performance could force a change in strategy or leadership. That freedom, however, also limits the ability of outside investors to influence how the company is run.

So, should Musk’s extraordinary voting control be viewed as a safeguard that allows SpaceX to pursue its long-term vision—or as a governance risk that leaves public shareholders with too little influence? Let’s take a closer look.

About SpaceX Stock

SpaceX designs, manufactures, and launches advanced rockets and spacecraft while also operating Starlink, its global satellite-internet network. Following its acquisition of xAI, SpaceX has expanded beyond launch services and broadband connectivity into AI, combining space infrastructure, satellite communications, and AI development under one platform. The company’s core businesses include reusable Falcon rockets, Dragon spacecraft, the Starship program, Starlink, and xAI’s products, including Grok. This broader structure positions SpaceX as a vertically integrated technology company focused on space transportation, global connectivity, and AI-powered infrastructure. With a market cap of $1.85 trillion, SPCX ranks as the world’s eighth-most valuable publicly traded company.

SpaceX shares have been highly volatile since the company’s record-setting IPO on June 12. SPCX stock surged from its $135 IPO price to more than $200 within its first three trading days. However, that optimism quickly faded as investors began questioning the company’s valuation, while concerns mounted that the expiration of post-IPO lockups could trigger a wave of selling. The stock fell to an all-time low of $104.83 on the first trading day of August but rebounded to finish the session with solid gains, followed by another advance the next day, as dip buyers stepped in ahead of the company’s first public earnings report. That rebound proved short-lived, as SPCX stock plunged after earnings amid investor concerns over the company’s massive AI spending plans. A day after the post-earnings selloff, SpaceX’s first lockup expiration failed to trigger the wave of selling many had expected, instead sparking short covering and dip buying that ultimately lifted the stock back above its $135 IPO price.

Elon Musk’s SpaceX Stake Is Huge, but His Voting Control Is Even Bigger

SpaceX, Elon Musk’s space, satellite, and AI company, said in a regulatory filing Thursday that its founder and chief executive officer owns a 48.4% stake. Musk holds 6.42 billion shares, according to the filing, implying a valuation of more than $900 billion.

The stake includes 849.5 million Class A shares and 3.92 billion Class B shares held through trusts for which Musk serves as trustee. It also includes around 1.30 billion restricted Class B shares held directly by Musk, as well as another 350 million shares that can be acquired through options exercisable within 60 days of June 30.

Still, Musk said on X that some of the shares counted toward his stake remain subject to vesting conditions. “A bunch of it only vests on extremely crazy good outcomes for SpaceX, so actual full vested percentage is lower,” he said. The shares in question are 1.30 billion restricted Class B shares, “the vesting of which is subject to the satisfaction of certain performance and other conditions,” according to the filing. Musk retains voting rights over those shares before they fully vest, meaning they are included in both his reported beneficial ownership and his voting power.

Musk controls more than 82% of SpaceX’s voting power despite owning less than half of the company’s economic equity. That is because SpaceX’s dual-class share structure grants 10 votes to each Class B share, compared with one vote for each publicly traded Class A share. So, he essentially has unilateral control over the company’s decisions.

For shareholders, that level of control is where the SpaceX story gets more complicated. On the one hand, it allows SpaceX to operate with the speed and long-term focus of a founder-led company. On the other hand, it leaves outside shareholders with limited ability to influence strategy, board decisions, or major corporate actions.

Musk Explains the Logic Behind His Dominant SpaceX Voting Power

Musk recently explained why he needs to retain so much control over SpaceX. And the reason is pretty simple. “I really just need to make sure that I can focus on long term,” Musk said in a July interview with The Economist. He clarified that, by “long term,” he meant a time horizon of five to 10 years.

Musk said one of the challenges of being a public company is the constant pressure to deliver strong results each quarter, which can discourage investment in projects that may take five to 10 years to pay off. At SpaceX, he said his goal is to extend consciousness beyond Earth and build a thriving civilization on the Moon, Mars, and elsewhere in the solar system. Musk said those ambitious goals would ultimately generate a very high return on investment, but pursuing them will require heavy spending in the near term.

Musk also pushed back against Wall Street’s tendency to punish companies for heavy spending, even when those investments are necessary to support long-term growth. Ironically, less than two weeks after the interview was published, SpaceX shares tumbled after the company posted higher-than-expected spending on its AI business in Q2, while finance chief Bret Johnsen said heavy capital expenditures are expected to continue through the rest of the year. The drop came even as SpaceX delivered stronger-than-expected revenue and a narrower loss in its first public earnings report.

Musk Sees AI and Starlink as the Engines of SpaceX’s Revenue Boom

Musk sees significant opportunities for SpaceX not only in its ambitions for the Moon and Mars but also in AI and Starlink, with the latter remaining the company’s financial engine. On the earnings call in early August, Musk said he expects SpaceX’s annualized revenue run rate to reach at least $100 billion by the end of the year. Musk also moved up SpaceX’s $1 trillion revenue target (not ARR) to 2030 from 2031 and said it is not inconceivable that the company could reach it as early as 2029. That dramatic revenue growth is expected to be driven by next-generation Starlink satellites, along with strong expansion in the company’s AI business.

Musk aims to expand AI capacity to more than 10 gigawatts by the end of 2027. That would mark a roughly tenfold increase from the 1.4 gigawatts of capacity reported at the end of June. Each gigawatt of AI capacity can generate $30 billion to $50 billion in annual revenue, according to Musk. So 10 gigawatts of capacity could generate up to $500 billion in annual revenue, representing half of Musk’s $1 trillion target. 

As for Starlink, Musk said in early August that the company’s space-based broadband service could provide the majority of the world’s internet connectivity within the next decade. At an all-hands meeting with SpaceX employees last week, Musk projected that AI-based internet traffic will exceed human internet traffic by a factor of 1,000 within five years. Starlink ended the second quarter with approximately 12 million subscribers and generated $4.29 billion in revenue. With that, the segment has plenty of room to grow, with Goldman Sachs analysts projecting that Starlink’s revenue will reach $144 billion by 2030.

Conclusion

Putting it all together, I do not view Musk’s extensive voting control as a negative for SpaceX investors. Instead, it serves as a safeguard that allows him to stay focused on executing the company’s long-term vision without the risk of being removed by shareholders if they become dissatisfied with short-term performance. If Musk delivers on his ambitious goals, SpaceX’s valuation could soar, ultimately benefiting shareholders.
