Shares in SpaceX continue to rise after the business went public last Friday, pushing its market cap to new heights.

The company's valuation rose another 15 percent this Tuesday, bringing its total cap to $2.94 trillion. That is above Amazon ($2.66trn) and Microsoft ($2.92trn), making it the fourth-largest publicly traded company in the world.

At IPO, SpaceX was worth $1.77trn, already the largest public listing in history.

The company this week announced that it planned to acquire AI coding start-up Cursor for $60bn. Cursor has used SpaceX's xAI data center infrastructure since April. The Colossus data centers are also used by Anthropic and Google.

SpaceX reported a net loss of $4.94 billion on $18.7bn in revenue last year.

Amazon had a net income of $77.7bn, with total revenues of $716.9bn. Microsoft's fiscal year ended June 30, 2025, when it reported a net income of $101.8bn and total revenue of $281.7bn.
