SpaceX (SPCX) stock rose 12% on Wednesday to $149.29. That is a 36% gain in five sessions and more than $500 billion in new market value.
The trigger was software, not rockets. SpaceXAI, the company’s artificial intelligence (AI) arm, shipped Grok 4.6. That division lost $1.26 billion last quarter.
