Analysis suggests that SpaceX's 105th calendar day, September 24, will allow insiders to sell some of their shares, potentially leading to up to $48.2 billion in selling pressure. Previously, SpaceX saw multiple rounds of stock lock-up expirations on August 6, August 20, and September 9. Analysis indicates that SpaceX's low free float and accelerated inclusion in major indices previously supported its stock price, but this positive effect is diminishing as more shares become unlocked.
