Here's Who Owns the Most SpaceX Stock

The question of who owns the most stock means more when you're asking about Space Exploration Technologies (NASDAQ: SPCX) than when you're asking about a typical public company. The June 2026 IPO floated a thin slice of the business -- nearly 4.3% of the equity -- which means the people and firms who held shares before the debut own the rest. The ownership structure that developed across two private decades when SpaceX was a private company is the one that governs it now that it's public, and it puts a small number of names in charge of a $2 trillion enterprise.

Elon Musk owns the most SpaceX stock

There is no contest at the top. Elon Musk holds close to 42% of the equity, a stake worth more than $1 trillion at the IPO valuation. Musk's block sits under a lockup that lasts until June 2027, with no early release provision, so the largest holder is a seller of nothing for the first year on the market.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue "

The outside investors who own the most SpaceX stock

Behind Musk, the biggest holder is a name many investors miss. Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL), the parent of Google, owns close to 7% of SpaceX, a position that can be traced to a $1 billion investment it made alongside Fidelity in January 2015 (Alphabet invested $900 million, with Fidelity contributing the remaining $100 million). That single check turned Google into the largest outside shareholder in the company, a bet on rockets from a search and advertising business.

The early venture backers hold the most striking returns rather than the largest slices. Founders Fund, a firm co-founded by Peter Thiel, wrote a $20 million check in SpaceX's 2008 Series C round, and that stake is now worth $50 billion. Sequoia Capital, Andreessen Horowitz, and Valor Equity Partners each hold positions of around 2% or below. The February 2026 merger with xAI added new faces to the list, including Nvidia and the Qatar Investment Authority, a sovereign wealth fund.

The employees and the public shareholders

One large block hides in plain sight. SpaceX pays its workforce with restricted stock units and options, so employees hold a collective stake that the company does not break out in its filings. That group has waited years for the tender offers, and the staggered lockup schedule that lets them sell, and the size of their holdings is one of the least visible parts of the ownership story.
