Picture 143% more houses suddenly on the market overnight. That's what SpaceX shareholders face Thursday when 911.5 million shares worth between $101B and $123B unlock for the first time. It's the single largest stock release in US public market history, arriving as the company's shares already dropped 11% after its first earnings report.

The company went public in June at $135 per share, but kept the initial float tiny, just 5% of total shares. That conservative structure was meant to manage volatility. The August 4 earnings report changed everything. Revenue beat expectations, yet the market fixated on two problems, capital spending is running hot and free cash flow is tightening. SpaceX also flagged a $540 million unrealized loss on Bitcoin holdings it refuses to sell.

The unlock schedule and what stays locked

Starting Thursday, employees, early investors, and venture capitalists can dump 20% of their holdings into public markets. The tradable float jumps from roughly 640 million shares to over 1.5 billion in a single trading session. More tranches arrive in coming months, but one batch stays put, a conditional release tied to SpaceX maintaining a $175.50 stock price. Shares never held that level, so those remain frozen. Elon Musk's personal stake stays locked until mid-2027.

Why Bitcoin losses matter here

SpaceX disclosed it made zero Bitcoin sales in Q2 despite the crypto asset tanking. That $540 million paper loss sits on the balance sheet, a reminder that even rocket companies now carry digital asset risk. Investors already worried about capex spending, and unrealized losses add another layer of concern about where cash is flowing.

The timing compounds pressure. Earnings miss becomes less about fundamentals and more about what happens when massive supply hits a weakened bid. Lockup expirations are notorious for creating volatility, and this one is operating at a scale the US market hasn't seen before. Musk's continued lockup through 2027 signals confidence, but that won't comfort shareholders watching 911 million shares hit order books in a single day.
