Musk Discloses 48.4% SpaceX Stake Worth Over $900B in SEC Filing

Elon Musk has filed a Schedule 13G with the SEC disclosing beneficial ownership of roughly 6.42 billion shares of SpaceX, giving him a 48.4% stake in the newly public rockets-and-AI giant.

SPCX trades on the Nasdaq after its record-breaking June IPO, and Musk’s filing puts hard numbers on just how much of the company he still controls post-listing.

What the filing shows

Musk held a 48.4% stake in SpaceX as of June 30, a regulatory filing showed on Thursday, valuing his holding at more than $900 billion at current market prices.

His reported holdings include 849,494,440 Class A shares and 3,916,980,790 Class B shares held by trusts, plus 1,302,072,285 restricted Class B shares and 350,000,000 Class B options. Each Class B share is convertible into one Class A share.

Musk said his fully vested ownership stake is lower because many of his shares carry demanding performance conditions.

Voting control is the real story

He has held more than 82% of SpaceX’s voting power since the IPO, emphasizing the extent of his sway over the company.

Class A shares provide one vote per share, while Class B shares provide 10 votes per share, significantly concentrating voting control. Translation for public shareholders: economic exposure, minimal governance say.

Lockup expired, stock rallied anyway

Wall Street had braced for heavy selling when the company’s largest lockup expired on Aug. 6, freeing 911.5 million shares, which is more than the number sold in its record IPO. Instead, the stock rallied 35% over the following five sessions.

The rebound erased the immediate lockup concerns, restored the shares above their $135 IPO price and added around $500 billion to SpaceX’s cap. Its first public earnings report also delivered stronger-than-expected revenue and a narrower loss, giving investors reasons to reconsider the selloff.

Options market and stocks to watch

Watch SPCX for continued flow around the filing and any follow-on disclosures tied to Musk’s performance-vesting shares. Post-lockup positioning and implied vol are the tells.

Watch TSLA as Musk-concentration headlines tend to bleed across his other names, particularly on any commentary about his time and capital allocation.

Watch GOOGL given Alphabet’s legacy pre-IPO SpaceX position, and watch defense/space-adjacent names like RKLB and LMT for any read-through on launch demand and competitive pressure.
