SpaceX Went From $150 to $225 and Back in Under 2 Weeks -- Here's the Math That Explains Every Dollar of That Move
The long-awaited IPO of Space Exploration Technologies ( SPCX +2.69% ) , or SpaceX for short, finally arrived on June 12. Shares shot up like a rocket on their first day of trading, soaring to $150 and then to $225 in short order. But the stock has reversed course just as quickly, falling back to around $150, a round trip that took place in under two weeks. A lot is happening with SpaceX right now, from rampant hype around space and artificial intelligence (AI) to the company's recent $60 billion acquisition of Cursor . But there is real, underlying math that helps explain why SpaceX stock is so volatile right out the gate, and what it might mean for the stock price moving forward. Looking at SpaceX's quick surge and sudden decline SpaceX was the largest IPO in history, and arguably one of the most hyped. There were tons of investors who wanted to buy shares. By design, SpaceX only made a small portion of its total stock publicly available on IPO day, just 4.24%. These publicly tradable shares are called the float. The small float and overwhelming demand for SpaceX shares created a classic supply-and-demand situation, in which the stock price rocketed higher in the days immediately following its market debut. But demand eventually peaks, and investors saw SpaceX reverse course after reaching about $225 per share. Image source: The Motley Fool. So, why did the stock cool off? There are probably a few reasons. First, SpaceX's stock was very expensive at its high. Second, the company is funding its $60 billion acquisition of Cursor with stock, diluting existing investors. The market often sells off stocks in these scenarios to reflect the anticipated dilution. Lastly, IPO day is often when excitement peaks. Investors then have a few days to step back and assess, and that hype and excitement usually fade a bit. Where is the rest of SpaceX's stock? Newly public companies have lockup periods that prevent insiders and employees from dumping their stock into the buying frenzy on IPO day. While typical lockup periods are around 180 days, SpaceX is using a staggered lockup period that gradually allows insiders to sell and expand the float at a controlled pace. The earliest selling window opens after SpaceX's first earnings report, assuming the stock meets certain share price thresholds. There are several windows after that, building up to the traditional lockup expiration after 180 days. Additionally, CEO Elon Musk and other significant investors are subject to a 366-day lockup, allowing them to begin selling shares on June 14, 2027. Remember, investors can currently trade only 4.24% of SpaceX's total shares. The current float of approximately 555.6 million shares could multiply as these lockups expire over the next year. Circling back to the supply-and-demand dynamic, a steadily growing float puts a thumb on the supply side of the scale. Today's Change ( 2.69 %) $ 4.24 Current Price $ 161.78 Looking at where SpaceX's share price might go from here Meanwhile, SpaceX still trades at a $2 trillion market cap, approximately 110 times its 2025 revenue of $18.6 billion. It remains one of the market's most expensive stocks, even after the recent dip. High valuations create high expectations. The selling pressure could intensify if SpaceX cannot deliver the growth to justify such a high valuation. There are several reasons to love SpaceX as a long-term investment. That said, the stock's quick dip from $225 could be a warning sign of how quickly SpaceX can shed value if market sentiment turns against it. Understanding how the float will expand over the coming year will help investors weigh the risks of buying shares now versus waiting for the dust to settle.
