Elon Musk has said in a public report that he owns 48.4% of SpaceX, a large American company that builds rockets and satellites. This information was given to the United States Securities and Exchange Commission, a government office that checks company records. As of 30 June 2026, Musk’s shares are worth more than $900 billion.

Musk revealed this because SpaceX became a public company in June 2026. A company becomes public when it starts selling shares on the stock market so people can buy part of the company.

Because of this share structure, Elon Musk still controls SpaceX’s most important decisions, even though he owns less than half the company. He has special shares that give him more voting power, so it is difficult for other investors to change company leadership.
