SpaceX、Amazon を上回り企業価値が2.7兆ドルに膨張

SpaceX passed Amazon to become the fifth-most valuable company in the world, after its stock price climbed 20% on Monday and more than 8% in early trading Tuesday, pushing its valuation past $2.7 trillion.

That’s despite Amazon turning a $78 billion profit in 2025 on $717 billion in sales last year, compared to SpaceX’s $4.9 billion loss on $18.7 billion in revenue. SpaceX has recently added new revenue streams in the form of compute leasing deals with Anthropic and Google, though, and the company has added $1 trillion to its valuation since going public on Friday.

Tuesday’s stock price jump came after SpaceX announced it is acquiring AI coding startup Cursor in an all-stock deal worth $60 billion. SpaceX first revealed a collaboration with Cursor in April, at a time when CEO Elon Musk said his AI company xAI — now a part of SpaceX — “was not built right [the] first time around” and that he was rebuilding it “from the foundations up.”

SpaceX’s historic IPO saw it debut with a valuation of around $1.7 trillion, and the transaction raised nearly $86 billion for Musk’s company. SpaceX only made about 4% of its total shares available for trading, which experts predicted would make the stock more susceptible to wild swings.
