Elon Musk’s xAI lost $6.4 billion from operations on just $3.2 billion in revenue in 2025, according to SpaceX’s IPO filings. And the losses are poised to grow. SpaceX’s filing reveals plans to scale Grok to “multiple trillions of parameters,” a dramatic boost that will likely require significant additional compute spend.
Elon Musk merged his AI company xAI — which had previously acquired his social media platform X (formerly Twitter) — with his rocket and satellite company SpaceX in February before announcing that he’d take the combined company public this year. While AI competitors OpenAI and Anthropic are also eyeing public debuts in 2026, SpaceX’s is expected to be one of the largest in history with a potential $1.75 trillion valuation.
