SpaceX Briefly Tops Microsoft in total market value, driving an unprecedented, multi-billion-dollar trading frenzy just days after executing the largest public listing in corporate history. The newly listed aerospace, satellite, and artificial intelligence conglomerate, trading under the ticker symbol SPCX on the Nasdaq, saw its share price rocket past $220 on Tuesday to touch an intraday peak of $225.64. This spectacular, vertical climb pushed the firm’s total market capitalization to a staggering $2.84 trillion, briefly vaulting it ahead of software giant Microsoft’s $2.92 trillion valuation before settling back to close near the $220 mark.
This rapid, post-IPO appreciation has permanently rewritten the hierarchy of Wall Street’s largest corporate giants. By closing comfortably above $220 per share, the company has officially surpassed e-commerce titan Amazon’s steady market capitalization of approximately $2.65 trillion. This makes SpaceX the fifth-most-valuable public enterprise on the planet, placing it ahead of semiconductor giant Broadcom at $1.8 trillion, oil producer Saudi Aramco at $1.7 trillion, and even its electric-vehicle sibling, Tesla, which currently holds a valuation of $1.4 trillion. Investors are now actively debating whether the brand has effectively transformed Wall Street’s “Magnificent Seven” into an elite, tech-industrial eight.
The primary catalyst driving Tuesday’s explosive price action was the highly anticipated launch of standardized options contracts for the stock. Cboe Global Markets officially opened trading for SPCX options on Tuesday morning, featuring strike prices ranging from $25 to an optimistic ceiling of $380. Options market analysts reported an immediate, overwhelming wave of speculative call-buying from both retail and institutional traders. This intense call demand forced market makers and dealers to aggressively purchase underlying SPCX shares to hedge their short-gamma positions, triggering a classic, options-driven “gamma squeeze” that drove the stock price higher.
To maintain this massive, tech-centric momentum, the company announced a monumental, $60 billion acquisition of artificial intelligence startup Anysphere, the developer of the popular AI-powered coding tool Cursor. The strategic cash-and-stock buyout aims to integrate advanced, automated coding and software development capabilities directly into the firm’s xAI and Starlink operating networks. By embedding autonomous software agents across its satellite and rocket platforms, the company wants to build a highly defensible, next-generation computing infrastructure. This acquisition has successfully reinforced the brand’s public image as an integrated “space-and-AI” titan rather than a traditional aerospace manufacturer.
The continued appreciation of the stock has also cemented the historic personal wealth expansion of its founder, Elon Musk. Musk remains the undisputed controller of the aerospace empire, holding approximately 42% of the total equity and commanding about 85% of its corporate voting power. At the current trading level, Musk’s personal holdings in the company are worth roughly $890 billion. When combined with his $260 billion stake in electric vehicle leader Tesla and his private holdings in artificial intelligence startup xAI, the successful listing has officially made Musk the world’s first trillionaire, with his total net worth estimated at an unprecedented $1.15 trillion.
A major catalyst driving this continuous price appreciation is the announcement that the underwriting syndicate, led by Morgan Stanley and Goldman Sachs, has fully exercised its overallotment “greenshoe” option. By purchasing an additional 83.3 million shares at the initial offering price of $135, the underwriters increased the total fundraising size of the IPO to a record-shattering $85.7 billion. This massive capital injection easily eclipses the previous global record of $29.4 billion set by state oil company Saudi Aramco in 2019, providing the company with an unmatched cash cushion.
This intense buying pressure has generated unprecedented, almost abnormal levels of trading activity across the Wall Street ecosystem. More than $9.1 billion worth of SpaceX shares changed hands within the first hour of trading on Tuesday morning, outtrading the combined trading volumes of market heavyweights Nvidia, Microsoft, Tesla, and Apple put together. This massive concentration of market liquidity has sucked capital out of other technology sectors, with major benchmark indices experiencing selective downward pressure as institutional managers liquidate other holdings to free up cash for the aerospace giant.
Market strategists explain that this extreme price volatility and massive trading volume stem primarily from the severe scarcity of the company’s public share float. Underwriters set the initial public offering to float only about 4.2% of the company’s total shares outstanding. Although underwriters subsequently exercised their “greenshoe” over-allotment option in full—purchasing additional shares to increase the total IPO proceeds to a record-shattering $85.7 billion—the public float still represents a tiny 4.9% of the company’s total equity. This exceptionally thin float means that even minor institutional buy orders can easily trigger a massive upward price squeeze.
Ultimately, the historic rise of the newly public stock has permanently rewritten the rules of modern corporate finance. By proving that public markets possess the depth to absorb a multi-trillion-dollar technology conglomerate, the company has officially re-energized a sluggish initial public offering market, paving a clear path for other highly valued private AI and tech giants to go public. The successful listing provides the firm with a massive $80 billion cash cushion, rendering its net debt negative and funding its long-term space exploration goals. As trading continues, this monumental listing will establish a powerful precedent, proving that the physical hardware providers building the backbone of the space and AI age command the ultimate premium.
