SpaceX Warning
I am becoming very alarmed at the number of people asking me about SpaceX who don’t know about the expiration of enormous lockups in the months ahead, which could unleash waves of selling and force its share price down.
I am not legally allowed to give you advice on next week’s IPO. Nor is this a comment on whether SpaceX will be a good investment in the years to come. It is simply a warning about the mechanics of insiders who could suddenly be allowed to sell in large quantities.
SpaceX has been a private company for 24 years. During that time, many original engineers, early investors, and large Wall Street players have acquired substantial amounts of stock that they may be anxious to finally sell. Initially next week, they will be prohibited from doing so.
But as the months tick by, those lockups will quickly expire on certain dates. SpaceX explains those rules in its SEC registration document, known as an S-1. Bloomberg summarizes them in the graphic below.
Cynics argue that SpaceX is only selling approximately 4.3% of its stock in next week’s IPO, so early demand might outstrip supply, causing the stock to initially pop, triggering great headlines. After that, Bloomberg estimates that 50% of all stock becomes eligible for what it calls 'early release' in stages, with all of it available to sell within 180 days. One hundred percent of all SpaceX stock can be sold after 366 days.
At a valuation of $1.75 trillion, that is an almost biblical amount of stock.
Just please be careful.
