SpaceX closes in on Amazon in sprint toward $3 trillion

SpaceX’s post-IPO surge pushed its market value to roughly $2.64 trillion at Tuesday’s close and briefly above Amazon and Microsoft intraday, making it one of the fastest companies ever to enter the megacap tier. The stock rose from a $135 IPO price to an intraday gain of about 67% and added nearly $1 trillion in value at its peak, including about $413 billion in a single day. The article frames the move as a major market milestone, with investors valuing SpaceX like a platform company rather than a speculative new issue. The rally was fueled by enthusiasm around Starlink, defense, launch services and AI-related infrastructure ambitions, and it also triggered a retail trading stampede. The key market takeaway is that valuation momentum is outrunning fundamental debate, while SpaceX now sits near the top of the U.S. public-company rankings alongside Nvidia, Alphabet, Apple, Microsoft and Amazon.
