Elon Musk filed a Schedule 13G with the SEC disclosing ownership of 6.42 billion SpaceX shares, representing a 48.4% stake in the company. The filing, submitted on August 13, provides the first precise numerical breakdown of Musk's shareholdings across the company's share classes.
SpaceX completed its initial public offering in June 2026 at a valuation that valued the company at roughly $210 billion. Musk's disclosed stake places him as the company's largest shareholder by a substantial margin. The Schedule 13G filing, which is used by investors to disclose passive ownership positions exceeding 5%, includes detailed composition of share classes and conversion rights.
The disclosure comes as SpaceX operates in its first months as a public company. Prior to the IPO, Musk's ownership percentage had been disclosed in general terms during roadshow materials and initial filings, but this Schedule 13G marks the first time the SEC filings contain the exact share count and percentage breakdown. The 6,418,547,515 share figure encompasses all share classes on a fully converted basis.
SpaceX's ownership structure came from decades of funding rounds and employee equity grants. The company had raised capital from venture firms including Sequoia Capital and Founders Fund before going public. Musk founded the company in 2002 and has retained operational control through the public transition.
Schedule 13G filings are standard SEC requirements for investors holding more than 5% of a public company's shares. The document provides transparency on insider ownership but does not necessarily restrict trading or impose the stricter reporting obligations that come with Schedule 13D designations, which flag activist or control-seeking positions.
Musk's 48.4% ownership stake exceeds the threshold at which a single shareholder typically requires board seat protections or can unilaterally block major transactions in most corporate governance structures. At this ownership level, Musk retains effective control over strategic decisions including mergers, capital allocation, and executive compensation.
The number that decides whether Musk maintains operational control is whether his ownership percentage falls below 40% through future dilution, which would occur if SpaceX issues new equity for acquisitions or employee compensation at a scale that materially expands the share count.
