SpaceX buys Musk’s xAI in record $1.25 trillion deal as space stocks jump premarket
New York, February 3, 2026, 08:26 — Premarket SpaceX has snapped up Elon Musk’s AI startup xAI, merging its rocket and satellite operations with the creators of the Grok chatbot. A source close to the deal pegged SpaceX’s valuation at $1 trillion and xAI’s at $250 billion—up from recent secondary-market estimates around $800 billion and $230 billion, respectively. xAI investors will get 0.1433 SpaceX shares per xAI share, the source added, with some execs able to cash out at $75.46 per share. PitchBook analyst Ali Javaheri highlighted Starlink as a “cash flow engine” amid LSEG data showing this is now the biggest M&A deal ever, beating Vodafone’s 2000 Mannesmann acquisition.
