Thursday marks a huge moment for SpaceX stock. More than 900 million shares (911.5 million to be exact) are becoming available for public trading. This will more than double the number of shares regular investors can buy and sell.
Important Point: This is called a "lockup expiry." When a company goes public, early investors and employees are usually blocked from selling their shares for a set time. That time just ran out for a massive batch of SpaceX shares.
Expert Take: "You have a few different things triggering volatile action in the name, all happening at the same time." – Ryan Lee, Direxion
Think of it like a time-locked safe. When SpaceX went public:
- Most shares stayed locked in the safe
- Keys handed out on a schedule (not all at once)
- Thursday = first big batch of keys handed out
| Typical Company | SpaceX |
|---|---|
| One 180-day lockup for everyone | Tiered, staggered unlocks over years |
| All insiders sell at once | Employees first, executives later, Musk last |
| Class | Amount | Main Holders |
|---|---|---|
| Class A | 7.571 billion | Employees & early investors |
| Class B | ~6 billion | Elon Musk & executives |
Important Point: Employees who got shares years ago (at very low prices) are sitting on huge gains even at $108. Many may want to cash out now.
Mark Your Calendar: Nasdaq 100 rebalances in September – that’s when the new share count gets officially factored in.
"An influx of new shares can weigh on any stock in the short term, but that doesn’t change the underlying picture. What matters most is the strength of the business and Musk’s ability to keep executing on the long-term vision." – Justus Parmar, Fortuna Investments
A lockup period is a contractual restriction preventing company insiders (employees, early investors, executives) from selling their shares for a set time after an IPO. It prevents a flood of shares from crashing the price on day one.
SpaceX chose a tiered calendar to avoid the classic "lockup cliff" where everyone sells at once. This spreads the selling pressure over years – though Thursday is still the biggest single unlock so far.
Nobody knows for sure. Musk has never sold SpaceX shares historically. He typically borrows against them instead. But 2027 is a long way off – many things could change.
If SpaceX’s weight in the Nasdaq 100 rises from 1% to 3.5%, your index fund will automatically buy more SpaceX stock during the September rebalance. You’ll have more exposure to SpaceX whether you like it or not.
That depends on your time horizon and risk tolerance. Short-term: high volatility likely. Long-term: depends on whether you believe in Starlink’s profitability, Starship’s success, and Musk’s execution. This is not financial advice.
