The 13G filing, submitted Thursday, shows Musk holds 6.42 billion shares of SpaceX Class A common stock as of June 30. That gives him a 48.4% stake in the company.
At current market prices, that position is worth more than $900 billion. But Musk was quick to push back on that number.
On X, he said that a portion of his shares “only vests on extremely crazy good outcomes for SpaceX,” meaning his actual fully vested percentage is lower than the filing suggests.
How Musk’s SpaceX Shares Are Structured
The shares break down into several categories. Around 849.5 million are Class A shares held in trusts where Musk serves as trustee. Another 3.92 billion are Class B shares in those same trusts.
He also holds 1.30 billion restricted Class B shares directly, and has options covering a further 350 million Class B shares. The filing states he has sole voting and dispositive power over the entire 6.42 billion shares.
Despite his economic stake sitting just below 50%, Musk controls more than 82% of SpaceX’s total votes. That gives him a firm grip on the company’s direction.
Musk’s 6.4 billion shares remain locked up until June 2027.
SpaceX Stock Has Had a Bumpy Start Since IPO
SpaceX went public on June 12, raising $85.7 billion in an IPO that briefly pushed its market cap past $2 trillion. The stock priced at $135.
Since then, the ride has been rough. Shares fell to a low of $105.11 earlier in August as nearly 911.5 million insider shares became eligible for sale for the first time.
At that point, the stock had dropped more than 50% from its June 16 peak of $225.64. It also sat about 20% below the IPO price.
The slide came after SpaceX’s first earnings report showed capital expenditures at more than twice the company’s revenue. Revenue of $7.8 billion did beat Wall Street estimates, though.
The stock has recovered some ground since then. On Thursday, SpaceX shares closed at $141.29, down 3.33% on the day, before rising to $143.40 in premarket trading Friday. Over the past month, the stock is up 3.83%.
One other notable disclosure came alongside Musk’s filing. Norway’s Government Pension Fund Global said it holds a 0.05% stake in SpaceX, worth just over $1.2 billion as of June 30.
