Space Exploration Technologies Corp. Class A Common StockSpaceX's IPO priced at $135 and its market cap is now ~$2.1T, but the stock has retreated ~33% from its record high, making the net read mixed.

OpenAI, Anthropic and SpaceX have reached a combined valuation of roughly $5.2 trillion, eclipsing the $4.1 trillion first-day value generated by 3,365 U.S. technology IPOs between 1980 and 2025. That $5.2 trillion total includes approximately $2 trillion for SpaceX, $2 trillion for Anthropic and $1.2 trillion for OpenAI, with OpenAI and Anthropic alone accounting for about $3.2 trillion, or roughly 62% of the three-company total, despite neither having reached public markets. SpaceX priced its June IPO at $135 per share, initially valuing it around $1.75 trillion, then opened at $150 and finished its first session at $160.95, pushing its market capitalization to roughly $2.1 trillion after raising about $75 billion. The stock later reached an intraday record of $225.64 before retreating sharply, closing Monday at $151.85, about 5.7% below its first-day close and nearly 33% below its record high. OpenAI has pushed back its IPO timetable and is not expected to list in 2026, while Anthropic has reportedly been considering a November offering at a valuation as high as $2 trillion, although timing and terms could still change.
