Three sessions, nearly $1 trillion in added market value. SpaceX is now worth more than Amazon and the rally is entirely a bet on businesses that don't yet exist at scale.
Elon Musk-owned rocket company, SpaceX’s (SPCX) stock has been on a roll since its rip-roaring debut on Wall Street last Friday. Until Monday, the stock has added 45% over and above its listing price of $133. And the rally’s momentum hasn’t faded, with SPCX defying S&P 500 and Nasdaq 100’s declines on Tuesday.
The runup has taken SpaceX’s valuation past e-commerce giant Amazon on Tuesday, positioning it as the fifth most valued global corporation, and also made its founder Musk the first trillionaire. According to Bloomberg Billionaires’ Index, the Tesla CEO’s net worth now stands at $1.27 trillion.
Here’s how SpaceX stock has fared in each trading session since its debut:

Why the Market Is Rewarding SpaceX
SpaceX's ascent into the world's five most valuable companies is remarkable not merely because of the speed of the move, but because of what it says about investor psychology. In just three trading sessions, the company added nearly $1 trillion in market value, leapfrogging giants such as Amazon and briefly challenging Microsoft in the global rankings. The rally has pushed SpaceX's valuation toward $2.7-$2.8 trillion, despite revenue and profitability metrics that remain well below those of the companies it now rivals in market capitalization.
Investors are not valuing SpaceX as a traditional aerospace company. Instead, they are assigning value to a collection of future businesses: Starlink's global broadband network, artificial intelligence (AI) infrastructure through xAI, defense and government contracts, next-generation launch services, and even long-term ambitions involving orbital computing and space-based data centers.
Investors are already paying an exceptionally high multiple relative to current sales, reflecting expectations that these businesses could generate enormous cash flows over the coming decade.
The Bottom Line
For futures traders, SpaceX's rise may be less a story about space and more a story about liquidity and risk appetite. Companies whose valuations depend heavily on profits expected many years into the future tend to benefit the most when investors are comfortable taking risk and when interest-rate expectations are falling. In that sense, SpaceX has become a real-time gauge of the market's willingness to pay for long-duration growth.
While bulls see a company building the infrastructure for AI, connectivity, and space commerce, skeptics point out that SpaceX's valuation now towers over its current revenue base, making execution risk increasingly important.
SpaceX's leap into the global top five is ultimately a statement about where investors believe the next trillion-dollar opportunities will emerge. The market is no longer valuing the company solely on rockets, satellites, or launch contracts. It is valuing the possibility that SpaceX becomes the backbone of multiple future industries—from AI infrastructure and global connectivity to defense technology and the commercialization of space itself. Whether that vision proves justified may determine not only SpaceX's future, but also how much investors are willing to pay for growth across the broader market.
