SpaceX insider shareholders will be permitted to sell 911.5 million shares beginning Thursday following the scheduled expiration of a lockup agreement that has restricted stock sales since the company's last major funding round. The shares are valued at approximately $123 billion at current prices.
Lockup agreements are standard in private equity and late-stage private company financings. They typically restrict founders, early investors and employees from selling shares for a set period, usually 180 to 365 days, to prevent a sudden supply surge that could depress valuations immediately after a transaction closes. SpaceX's expiring lockup covers insiders who received shares through the company's most recent funding events.
The 911.5 million shares represent roughly 325 percent of SpaceX's current public float of approximately 280 million shares, according to available holdings data. No secondary market for SpaceX shares currently exists, meaning the lockup expiration itself does not immediately open a trading venue. The significance of the expiration lies in the legal permission it grants: insiders may now negotiate secondary sales, structure tender offers, or otherwise move shares in private transactions without contractual restriction.
SpaceX has not announced how much of the freed stock insiders intend to sell or on what timeline. The company announced the lockup expiration date alongside second-quarter earnings released August 4. Founder and Chief Executive Elon Musk holds approximately 42 percent of SpaceX equity, according to company disclosures, making him the largest shareholder by far.
The company is currently valued at approximately $210 billion in private market transactions, down from a $180 billion valuation in its previous funding round in 2024. Secondary share trading has slowed this year as investors reassess growth projections for the Starship program and demand for Starlink satellite internet services.
The removal of lockup restrictions on more than 900 million shares while the company trades in a depressed private market creates the conditions for insider sales, though the pace and volume depend entirely on shareholder decisions. The market discount to prior valuations and the scale of newly available shares are the two factors that will determine whether, and how quickly, insiders choose to liquidate positions.
