SpaceX's market capitalization has soared to $3 trillion: the secret lies in the stock shortage
The market has witnessed a phenomenon that is rewriting the rules for valuing public companies. SpaceX shares (ticker SPCX) have surged from an initial public offering valuation of $1.75 trillion to a market capitalization of around $3 trillion in less than a week. This has allowed Elon Musk's company to surpass tech giants like Amazon and Microsoft in this metric. Analysts describe such a leap as unprecedented.
What is the reason for this rapid growth? The answer lies not in fantastic production successes or new contracts, but in a unique market mechanic — an extremely low volume of shares in free float. During the IPO, only about 4% of the total issued shares entered the market. The remaining 96% are locked up with insiders, employees, early investors, and large institutional holders according to a phased unlocking schedule.
The Mechanics of Scarcity: How 4% of Shares Create a $3 Trillion Market Cap
When buyers enter the market, they hit a tiny volume of shares available for trading. There are virtually no sell orders in the order book, so the price is forced to rise in jumps to draw out any sellers at all. Demand runs into a supply shortage, and each new wave of purchases pushes the price significantly higher.
The key nuance lies in how market capitalization is calculated. It is calculated based on all issued shares, including the locked-up 96%. Therefore, the final figure exceeds $3 trillion, even though only a small portion of the shares are actually traded. This is an example of the mechanics of an extremely low free-float (the proportion of shares in free circulation) on an unprecedented scale.
What Will Change After the Unlock
Insiders are not yet allowed to sell: the unlocking is happening in phases. The first major batch will hit the market in August, after the debut earnings report, with subsequent batches in the fall, tied to financial results, and the rest distributed through December. Additionally, Elon Musk's own shares are locked for 366 days.
For now, supply is effectively locked up, but this is temporary. With each unlock date, the number of available shares will increase in waves. And if purchases were mostly speculative, the balance could shift sharply once sellers gain access to the market.
My analysis: The situation with SpaceX is a classic example of a "short squeeze" on steroids. The $3 trillion market cap is more of a mathematical artifact than a reflection of the business's real value. Investors entering a position at current levels should be prepared for high volatility and a potential price collapse as locked-up insider shares hit the market. This is a game with extremely asymmetric risk.
