SpaceX is now worth more than Amazon. Shares of the newly public rocket and satellite company climbed 3.9% to push its market capitalization past Amazon’s, making SpaceX the fifth-largest public company in the United States. The stock has been trading above $208, representing a gain of more than 50% from its IPO price of $135 per share just days earlier.
Amazon, valued at roughly $2.66 to $2.72 trillion, now sits behind a company that didn’t even have a public stock ticker a week ago. SpaceX’s market cap during the surge reached between $2.75 and $2.84 trillion, with some estimates briefly exceeding $3 trillion.
The IPO that rewrote the record books
SpaceX went public on June 12, 2026, in what became the largest initial public offering in US history. The company raised $75 billion by selling 555.6 million shares at $135 each, valuing the business between $1.75 and $2 trillion at debut.
Shares closed their first trading day at $160.95, putting the implied market cap at roughly $2.1 trillion. By June 16, just four days after the IPO, the stock had surged past $208 per share, putting investors who bought at the offering price on returns north of 50%.
