SpaceX is set for a further increase in shares available for sale after 911 million shares were released earlier this month, adding to investor scrutiny of how upcoming unlocks could affect the stock. Another block of shares is due to unlock on August 20, with more releases scheduled for September and October. The expanding supply comes as enthusiasm around SpaceX’s record IPO remains high, prompting closer attention to whether the scale of these unlocks could pressure the market in the coming months.
