SpaceX-xAI merger reportedly finalized at $1.25 trillion valuation, deal terms not fully disclosed
42% confidenceElon Musk was reported in advanced talks to combine SpaceX with xAI beginning in early February 2026, with CNBC later reporting the merger closed at a $1.25 trillion combined valuation; xAI itself was said to be burning close to $1 billion per month against roughly $500 million in annualized revenue at the time, but neither company has published full deal terms, equity split, or governance structure.
Reported by Bloomberg and CNBC citing people familiar with the matter; Musk, SpaceX and xAI have not issued a joint public statement detailing final terms, and the $1.25 trillion valuation and burn-rate figures remain sourced to unnamed insiders rather than company filings.
