SpaceX has officially entered the pantheon of the world’s most valuable public companies. After completing what is now the largest initial public offering in history, the aerospace and satellite internet giant sits at a market capitalization that places it sixth among all publicly traded US companies, trailing only Nvidia, Alphabet, Apple, Microsoft, and Amazon.
The company priced its IPO at $135 per share on June 11-12, 2026, raising approximately $75 billion in the process. To put that in perspective, the previous record-holder for largest IPO, Saudi Aramco, raised $25.6 billion back in 2019. SpaceX nearly tripled that.
From $135 to $161 in a single day
The stock opened at $150, already an 11% premium over the IPO price. By market close, shares had climbed to around $161, pushing SpaceX’s market capitalization above $2 trillion.
The surge had a particularly notable consequence for one individual. Elon Musk, who already held the title of world’s richest person, became the world’s first trillionaire following the stock’s debut performance.
