SpaceX shares tumbled 6% on August 5 even after crushing earnings expectations. The reason is simple: tomorrow morning, over 911 million shares held by early employees and investors are finally tradable. That's roughly $104 billion worth of stock flooding into the market at once.
The company went public earlier this year at $135 per share. Since then, insiders have been locked up, unable to sell. Tomorrow that changes. With SpaceX trading around $114 right now, the unlock represents a massive potential supply shock. The market is already pricing in the fear.
Here's what happens next. SpaceX has about 1.3 billion shares outstanding today. After tomorrow's unlock, that number jumps to 1.55 billion shares, a 6.91% dilution in one go. That's the kind of move that can spook shareholders, even when the business is firing on all cylinders. The company posted record quarterly results, but the stock barely held steady.
There's a wrinkle though. SpaceX didn't unlock the full batch that was technically eligible. Another 455 million shares would have come free, but they didn't. The reason: the stock never traded 30% above the IPO price for five consecutive days around the earnings announcement. So those stay locked for now. The next big unlock, 1.3 billion shares, is scheduled for late October or early November after the second earnings report.
With market cap now at $1.7 trillion, SpaceX is already one of the most valuable private companies ever to go public. But tomorrow's share flood will test whether that valuation holds. Traders are bracing for volatility. The fundamentals might be strong, but math is math: more shares outstanding means each piece of the pie gets smaller, at least on paper.
