SpaceX Surpasses Amazon to Become World's Fifth Most Valuable Company Days After Historic IPO

Just days after executing the largest initial public offering in history, SpaceX has fundamentally reordered the upper echelon of the global stock market. Shares of Elon Musk’s aerospace and artificial intelligence conglomerate surged in early trading this week, pushing the company's market capitalization past $2.7 trillion and officially leapfrogging Amazon to become the fifth most valuable public company in the world.[2][3][5]

The milestone caps a historic debut for the stock, which trades under the ticker SPCX. After pricing its IPO at $135 per share on June 12, the stock rallied nearly 50% over its first three trading sessions, briefly eclipsing Microsoft's $2.92 trillion valuation in intraday trading before settling comfortably ahead of Amazon's $2.65 trillion market cap.[4][5][7]

The sheer scale of the offering has shattered Wall Street records. Initial demand was so overwhelming that underwriters fully exercised their "greenshoe" option, increasing the total capital raised from $75 billion to $85.7 billion. The resulting valuation surge has also propelled Musk's personal fortune to an estimated $1.1 trillion, making him the world's first trillionaire.[1][4][7]

Investors flocking to the stock are buying into a sprawling technological empire rather than a pure-play rocket manufacturer. The newly public entity encompasses SpaceX's core orbital launch business, the highly profitable Starlink satellite internet constellation, the social media platform X, and Musk's artificial intelligence venture, xAI.[1][2]

Underscoring its aggressive expansion into the AI sector, SpaceX announced a massive $60 billion all-stock acquisition of Anysphere, the startup behind the popular AI coding assistant Cursor, on the same day it surpassed Amazon. Analysts view the acquisition as a direct challenge to Microsoft and Anthropic, integrating advanced code-generation capabilities into xAI's existing Grok models.[1][4][6]

Market strategists note that the stock's explosive upward momentum is being heavily amplified by artificial scarcity. Only about 4.9% of SpaceX's total outstanding shares were made available to the public in the IPO. This limited float, combined with massive retail investor demand and a frenzy of newly listed options trading, has created a supply squeeze that is driving prices sharply higher.[4][6]

Despite the enthusiasm, some financial analysts are urging caution, pointing to a stark disconnect between the company's multi-trillion-dollar valuation and its current balance sheet. SpaceX reported $18.7 billion in revenue and a net loss of $4.9 billion in 2025. At its current market cap, the stock is trading at roughly 128 times its 2025 sales—a staggering multiple compared to the broader S&P 500 average of 3.7.[1][8]

Bulls, however, argue that traditional valuation metrics fail to capture the company's near-monopoly on orbital payloads and the recurring revenue potential of Starlink, which is projected to bring in $11.4 billion this year alone. Musk has publicly stated that he expects the conglomerate to generate $1 trillion in annual revenue by 2031.[1][8]

Looking ahead, the stock is expected to face continued upward pressure from institutional buyers. SpaceX is slated for fast-track inclusion into major indices, including the Nasdaq 100, FTSE Russell, and MSCI, by the end of June. This will force passive index funds and exchange-traded funds to purchase massive blocks of shares, regardless of the underlying valuation.[4]

As the dust settles on Wall Street's biggest event of the decade, the focus now shifts to execution. With a valuation that prices in years of flawless growth and a newly acquired $60 billion AI division to integrate, SpaceX must now prove it can scale its revenues to match the historic expectations set by its public debut.[6][8]
