The first batch of SpaceX investors will have the opportunity to cash out their shares on Thursday as the lock-up period following the listing expires. The stock price has already fallen by more than 50% from its peak in mid-June, and this change may further pressure it. Over 911 million SpaceX shares, accounting for approximately 7% of the outstanding shares, will become tradable at that time, a quantity higher than the 639 million shares sold in its record-breaking IPO.
