SpaceX employees can begin selling shares on Thursday, August 6, 2026, as the company’s first lockup expiration lifts restrictions on up to 911.5 million insider shares, marking a potential turning point for the thousands of workers who became millionaires when the company went public in June.
The aerospace company priced its initial public offering at $135 per share on June 12, 2026, creating what many outlets called the largest IPO ever completed. More than 4,400 current and former employees became millionaires through stock holdings accumulated over the company’s decades of private operation, according to an analysis cited by The New York Times, with about 400 of them holding stakes worth $100 million or more.
The August 6 unlock represents only the first tranche of a staggered release schedule. On this date, insiders may sell up to 20% of their eligible shares, a deliberate departure from the typical 90- to 180-day lockup period used by most companies. SpaceX designed the schedule to spread sales across multiple dates rather than allowing all insider shares to flood the market at once.
Why the Staggered Approach Matters
A lockup period prevents founders, employees, and early investors from immediately selling stock after an IPO, protecting the public market from a sudden supply shock that could crash the share price. SpaceX’s staggered method reflects the company’s unusual position: the supply of shares becoming available on August 6 alone—roughly 911.5 million—exceeds the entire public float, which currently stands below 280.1 million shares, according to The Motley Fool.
Insiders have strong incentive to sell. Most pre-IPO investors and employees received their shares at prices far below the $135 IPO price. The Motley Fool noted that the company even warned in its prospectus that employees are “in great demand,” suggesting some could wait to sell shares and then leave for rival companies offering lucrative signing bonuses. The supply-and-demand dynamics could pressure the stock, though insiders may also choose to hold shares in anticipation of long-term gains.
The August 6 unlock is only the beginning. Additional tranches unlock on a rolling schedule over the following months, with the largest—1.3 billion shares—scheduled to unlock after SpaceX reports its fall financial results, according to The New York Times. This multi-month release gives employees and early investors a series of windows to monetize their holdings while limiting the immediate market impact of any single unlock date.
