SpaceX's market valuation surged past Amazon to become the fifth-most valuable company in the world, reaching more than $2.7 trillion on Tuesday following a 20% stock gain Monday and an additional 8% climb in early Tuesday trading.
The company's IPO launched Friday at a $1.7 trillion valuation, meaning SpaceX added $1 trillion to its market value in just six trading days. Tuesday's spike came hours after the company announced an all-stock acquisition of Cursor, an AI coding startup, valued at $60 billion.
The valuation milestone stands in sharp contrast to SpaceX's financial performance. In 2025, the aerospace and space infrastructure company reported a $4.9 billion loss on $18.7 billion in revenue. Amazon, by comparison, posted an $78 billion profit on $717 billion in sales for the same period.
SpaceX has been building new revenue streams beyond its traditional launch and satellite business. The company recently signed compute leasing deals with Anthropic and Google, adding capacity for AI workload offloading. CEO Elon Musk's xAI, now part of SpaceX, is also pursuing AI product development—Musk said in April that xAI "was not built right the first time around" and that he was rebuilding it "from the foundations up."
The Cursor acquisition represents a strategic push deeper into AI tooling. Musk and SpaceX first revealed a collaboration with Cursor in April, before formulating the acquisition as an all-stock deal.
Stock volatility has been pronounced since IPO. Experts noted that only 4 percent of SpaceX's total shares were made available for public trading, a constraint that market analysts predicted would amplify price swings. The tight float and rapid consecutive gains align with that forecast.
