#SpaceXMarketCapSurpassesMicrosoftRanksTopFiveGlobally SpaceX Soars Past Amazon, Briefly Tops Microsoft in Historic Market Cap Rally

SpaceX has rocketed into the top five global companies by market capitalization, surpassing Amazon and briefly overtaking Microsoft in a stunning post-IPO rally that has reshaped the corporate leaderboard .

The Elon Musk-led aerospace and technology company saw its stock climb approximately 4% on Tuesday, pushing its market value to an intraday peak of **$2.94 trillion**—briefly edging past Microsoft's $2.93 trillion valuation . While it settled the day at around **$2.65 trillion**, this still comfortably placed SpaceX ahead of Amazon ($2.64 trillion) and cemented its position as the fifth-largest public company globally .

A Record-Breaking Debut

This meteoric rise follows what is being called the largest IPO in history. SpaceX priced its public offering at $135 per share** on June 12, 2026, raising an initial **$75 billion . Underwriters later exercised their greenshoe option, lifting total proceeds to $85.7 billion .

The stock's performance has been extraordinary:

· Surged 20% on its first full trading day
· Gained another 6% on Monday
· Jumped ~4% on Tuesday, bringing total gains to roughly 50% from the IPO price in just four sessions

At Tuesday's highs, the stock had rallied 67% from its IPO price, adding nearly $1 trillion in market value .

The New Elite Club

SpaceX now trails only Nvidia ($5.09T), Alphabet ($4.46T), Apple ($4.34T), and Microsoft ($2.92T) among the world's most valuable public companies . The company leapfrogged Amazon—which needed nearly three decades to achieve similar market standing—in just three trading days .

Trading volume has been staggering, with over $23.1 billion worth of SpaceX shares changing hands by mid-Tuesday—several times higher than the combined volume of Nvidia, Microsoft, Tesla, and Apple .

Financial Reality Check

The valuation milestone comes despite SpaceX's challenging financials. The company generated $18.7 billion in revenue in 2025** but reported a **net loss of $4.9 billion . It also posted a $4.28 billion loss during the first quarter of 2026 .

Nevertheless, investors are betting heavily on SpaceX's dominance in reusable rockets, satellite communications (Starlink), defense contracts, and artificial intelligence—sectors viewed as critical for long-term growth .

Musk's Trillionaire Status

The rally has also propelled Elon Musk back to the top of global wealth rankings. His substantial stake in SpaceX, combined with the stock's historic post-IPO performance, has widened his lead as the world's richest person .
