SpaceX made its debut in public markets on June 12, attracting considerable attention with an initial share price of $135. Shares opened near $150 and surged over 19% in the first trading session, elevating the company’s market capitalization to over $2 trillion within hours of trading.
Interestingly, during after-hours trading, market capitalization estimates briefly hinted at values approaching $3 trillion. At that time, Microsoft, another major player, was trading around $2.9 trillion, making any claims of overtaking highly speculative and uncertain.
Delving into what transpired on the first day reveals that SpaceX sought a valuation of nearly $1.75 trillion. The stock began trading at approximately $150 per share and maintained an upward trajectory, reaching milestones between $176 and $192 throughout the day. This swift increase translated to a market cap exceeding $2 trillion, with some metrics suggesting intraday peaks reaching as high as $2.5 trillion, all figures that hold substantial reliability. The rumored $3 trillion valuation, however, arises from less verified reports circulating during after-hours.
To contextualize the public transition, it's significant to note that SpaceX's valuation experienced remarkable growth from about $350 billion in late 2024 to a range of $800 billion to $1.25 trillion by early 2026. Public market reception indicates these estimates were perceived as underwhelming.
What fuels investor enthusiasm surrounding SpaceX? Key factors include Starlink, which facilitates satellite broadband connectivity in previously underserved areas—including for maritime and military applications—alongside the Starship, a reconfigurable launch vehicle designed to revolutionize space travel economics. Each successful test and operation significantly reduces the costs associated with accessing space.
For those interested in the cryptocurrency market, it is crucial to clarify that SpaceX's IPO does not incorporate cryptocurrency assets or blockchain-related offerings. This event stands distinctly within traditional equity frameworks, emphasizing that the grandest capital market developments of 2026 are occurring via established financial systems.
Nevertheless, the investment landscape here harbors significant volatility risks. A stock recording a 19% rise on its inaugural day is equally susceptible to a 19% decline. The disparity between the initial valuation of $1.75 trillion and the intraday highs suggests that market enthusiasm significantly drives investor sentiment, which could lead to rapid shifts in valuation over time.
