Wall Street funds are pouring into Elon Musk's space empire at an unprecedented pace. After setting a record for the largest IPO in human history on June 12th with a $135 offering price and a staggering $75 billion raised, SpaceX (NASDAQ: SPCX) stock has been on a runaway train. Following a 19% gain on its first day of trading and a nearly 20% surge on Monday (June 15th), the market behemoth's upward momentum shows no signs of stopping.
It broke through $210 in pre-market trading, overtaking Amazon to become the fifth largest seller globally.
Entering the pre-market trading session on June 16, 2026, SPCX maintained its extreme strength, with its stock price surging by more than 10% at one point, reaching the $210 to $213 range. This fierce surge steadily pushed SpaceX's total market capitalization to approximately $2.8 trillion , and even briefly broke through the historic $3 trillion mark during the session.
This means that SpaceX has officially surpassed e-commerce giant Amazon, with a market capitalization of approximately $2.66 trillion to $2.72 trillion, successfully becoming the world's fifth-largest publicly traded company. Currently, only four traditional tech giants remain ahead of SpaceX:
- NVIDIA: Approximately US$5.1 trillion
- Google (Alphabet): Approximately $4.4 to $4.5 trillion
- Apple: Approximately $4.3 to $4.35 trillion
- Microsoft: Approximately $2.9 to $3.0 trillion
Are P/S valuations raising concerns about a potential bubble?
Market analysts point out that this almost frenzied buying reflects investors' extremely high expectations for SpaceX's cutting-edge businesses, such as rocket launch technology, Starlink low-Earth orbit satellite network, and space AI infrastructure.
However, some Wall Street institutions have begun to sound the alarm. Data shows that SpaceX's total revenue in 2025 is approximately $18.7 billion. Although it is in a period of rapid growth, it still faces certain profit pressures. Based on its current market capitalization of nearly $3 trillion, its price-to-sales ratio (P/S) has far exceeded that of the top four traditional tech giants, sparking a heated debate in the market about whether the "space bubble" is overheated.
