- SpaceX jumped 4.8% Tuesday to a $2.659 trillion market cap, leapfrogging Amazon.com ($2.646 trillion) for the No. 5 slot among largest U.S. companies, behind Nvidia ($5.07T), Alphabet ($4.50T), Apple ($4.38T), and Microsoft ($2.93T)
- In just its first two full days of trading, SpaceX added roughly $537 billion in market value, per FactSet data
- SpaceX announced a $60 billion all-stock deal to acquire vibe-coding startup Cursor, using its surging shares as currency
- The Cursor acquisition is designed to strengthen SpaceX's Grok AI division against rivals Anthropic and OpenAI
- The market-cap surge hands Elon Musk 'hundreds of billions of dollars out of thin air' he can redeploy for operational advantage, per Axios
Why it matters: Two days of trading generated $537 billion in paper value—roughly nine times the $60 billion SpaceX immediately deployed to buy Cursor—giving Musk stock-based firepower that lets him convert market enthusiasm directly into AI assets while rivals Anthropic and OpenAI were still digesting their own funding rounds.
