SpaceX continued its strong post-IPO rally on Tuesday, with shares rising about 13%, pushing the company past Microsoft to become the fourth-largest publicly traded company in the United States by market value.
According to the report, SpaceX’s market capitalization reached approximately $2.94 trillion, edging above Microsoft’s $2.93 trillion valuation. The latest gains follow a blockbuster market debut last week and a 20% jump during the stock’s first full trading day.
Investor enthusiasm was further boosted by SpaceX’s announcement that it will acquire AI coding startup Cursor for $60 billion. The deal strengthens the company’s growing presence in artificial intelligence.
Elon Musk also fueled optimism by suggesting SpaceX could generate roughly $1 trillion in annual revenue by 2030. However, the report noted that the company recorded a net loss in 2025 and remains under pressure to deliver on ambitious growth targets.
While some analysts remain cautious about SpaceX’s valuation, others believe its long-term prospects in space technology and AI continue to attract strong investor interest.
