SpaceX Shares Crashed & Investors Did Something Unexpected

Keypoints:

• • SpaceX shares sank nearly 14% Wednesday to an all-time low of $108.27
  • 911.5 million insider shares, worth roughly $100 billion, unlocked Thursday
  • The unlock more than doubled SpaceX's public float, from 4.9% to 11.8% of shares outstanding
  • SPCX still rose more than 6% on unlock day itself, defying the selling pressure everyone expected
  • Another 319 million shares unlock August 20, with more tranches following Q3 earnings
  • Elon Musk's own 6.4 billion shares stay locked until June 2027

$100 billion worth of stock became sellable overnight. Somehow, that turned out to be the good news, and the sequence of events leading up to it is what makes this one worth understanding rather than just skimming the past.

SpaceX shares sank nearly 14% Wednesday to an all-time low of $108.27, its second-worst trading day on record, right before 911.5 million insider shares became eligible to trade Thursday. That unlocked more than doubled the company's public float, lifting the freely tradable share of stock from 4.9% to 11.8% of shares outstanding. 

On paper, that's exactly the kind of supply flood that should push a stock lower, more sellers with the ability to sell almost always means more downward pressure, and Wall Street had been bracing for it for weeks.

Instead, SPCX rose more than 6% on unlock day itself, defying the very selling pressure everyone had priced in. Bank of America's Ron Epstein called the unlock more of a near-term technical drag than any real verdict on the underlying business, and analysts at Mizuho pointed out something easy to forget in the moment, shares becoming eligible for sale never guarantees the full tranche actually gets sold. Plenty of insiders holding for the long term simply don't cash out the day they technically can.

It's also far from over. Another 319 million shares unlock August 20, with additional large tranches following SpaceX's Q3 earnings and continuing into October, while Musk's own 6.4 billion shares stay locked until June 2027. 

This week wasn't the test. It was the first of several, and the market's calm reaction to round one says more about investor patience than it does about the stock being safely past the risk.
