SpaceX Ownership: How Much of the $2 Trillion Company Does Musk Own?

A new SEC filing puts Elon Musk’s SpaceX holding at 48.4%, or roughly 6.42 billion shares worth more than $900 billion. The same stake carries over 82% of the company’s votes.

That gap between ownership and control now decides everything SpaceX does, including what happens to its Bitcoin. How Much of SpaceX Does Elon Musk Own? Musk reported sole voting and dispositive power over all 6,418,547,515 shares. The count reflects his position as of June 30.

Four buckets make up the total. Trusts where Musk serves as trustee hold 849.5 million Class A shares and 3.92 billion Class B shares. He directly holds 1.30 billion restricted Class B shares. Options on 350 million more Class B shares complete the figure.

However, Musk says the 48.4% headline flatters his real position. A bunch of it only vests on extremely crazy good outcomes for SpaceX, so actual full vested percentage is lower— Elon Musk (@elonmusk) August 13, 2026 Musk.
