In a historic shift on Wall Street, Elon Musk’s SpaceX has officially overtaken retail giant Amazon to become the world’s fifth most valuable company. This monumental achievement occurred just days after SpaceX made its highly anticipated Initial Public Offering (IPO) on the Nasdaq index. Fueled by a massive wave of retail investor enthusiasm and a strategic expansion into artificial intelligence, the aerospace and technology giant has rewritten the record books of global finance.
The Record-Breaking IPO Rally
SpaceX launched its public debut on Friday, June 12, 2026, pricing its shares at $135 in what became the largest IPO in history. The initial offering raised an unprecedented $75 billion, which was quickly increased to $85.7 billion after underwriting options were exercised.
Upon hitting the open market, the stock experienced a blistering, parabolic rally. Driven heavily by intense retail trading demand, the stock surged by roughly 60% over its first three days of trading. On Tuesday, June 16, SpaceX shares jumped another 13% at the opening bell, pushing the company’s market capitalization as high as $2.97 trillion. This surge allowed it to eclipse Amazon’s market valuation of $2.64 trillion, cementing its position in the top five globally. Although the stock later eased slightly to settle around $2.8 trillion, it comfortably held its lead over Amazon.
Strategic Shift: The $60 Billion Cursor Acquisition
The momentum that pushed SpaceX past Amazon was supercharged by a major corporate announcement. On Tuesday morning, SpaceX announced it had agreed to acquire Anysphere, the startup behind the highly successful AI-powered coding application, Cursor, in an all-stock deal valued at $60 billion.
This acquisition is designed to directly benefit xAI, the artificial intelligence venture that recently merged with SpaceX. By absorbing Cursor, SpaceX aims to dominate the highly lucrative field of automated software engineering. Generative AI systems that write code have proven to be immense commercial successes, and the inclusion of Cursor allows SpaceX to enhance its native AI models, such as Grok.
Billionaire investor Bill Ackman noted that SpaceX’s soaring stock price acted as a major financial lever for the deal. Because the company’s valuation is so high, it was able to fund the massive acquisition entirely through stock without diluting existing shareholders significantly or using any cash proceeds from the recent IPO.
Disparity in Financial Realities
While market sentiment has placed SpaceX above Amazon in valuation, analysts have pointed out a massive gulf between the financial fundamentals of the two conglomerates:
- Amazon remains a highly profitable machine, posting over $717 billion in revenue and $78 billion in net income over the last fiscal year.
- SpaceX, by contrast, brought in $18.7 billion in revenue but recorded an operational net loss of $4.94 billion, largely due to heavy investments in its capital-intensive programs and its recent merger with the money-losing xAI.
Currently, SpaceX’s valuation premium is insulated by the immense commercial success of Starlink, which has crossed 10 million users and generates over $700 million in monthly revenue. Additionally, the company holds a structural safety net through a $4.2 billion NASA contract and an $8.5 billion national security contract backlog.
Musk Becomes the World’s First Trillionaire
The stunning market reception of the IPO has had an unprecedented impact on personal wealth. Elon Musk, who retains a massive 42% stake in SpaceX alongside his major holdings in Tesla, has officially become the world’s first trillionaire. Forbes estimates Musk’s net worth has soared past the $1.1 trillion threshold, reaching as high as $1.4 trillion during peak trading.
Looking ahead, SpaceX is set to be fast-tracked into major global benchmarks like the Nasdaq 100, FTSE, and MSCI indices, which will trigger mandatory buying from passive index funds and likely sustain trading momentum.
