xAI burned $6.4B last year. SpaceX's IPO filing shows why the spending is far from over | TechCrunch

xAI recorded large operating losses relative to revenue, with losses rising from $1.56 billion on $2.62 billion revenue in 2024 to $6.4 billion on $3.2 billion revenue in 2025. The gap between spending and earnings is widening. Revenue growth came mainly from AI solutions and infrastructure, including X and Grok subscription revenue and data licensing, plus advertising. Capital expenditures for the AI segment increased sharply, with spending in early 2026 implying a much higher annualized run rate. Grok user adoption remains limited, with 117 million monthly active users for Grok features out of 550 million combined MAUs across Grok and X. Plans include scaling Grok to multiple trillions of parameters, likely requiring additional compute.

"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."

"The filing marks the first public glimpses into xAI, and therefore X's, financials. In 2024, xAI recorded a loss of $1.56 billion on $2.62 billion in revenue. By 2025, losses had ballooned to $6.4 billion on $3.2 billion, meaning the gap between what xAI earns and spends is widening."

"The jump in revenue from 2024 to 2025 came in large part from "AI solutions and infrastructure revenue" totalling $465 million, which includes $365 million in X and Grok subscription revenue, and $88 million in data licensing. An additional $116 million came from advertising."

"AI segment capital expenditures climbed from $12.7 billion in 2025 to $7.7 billion in the first quarter of 2026 alone. That's an annualized capex run rate of about $30.8 billion, more than doubling year-over-year. So far, that investment has resulted in growing, but still limited, user numbers. Per the filing, SpaceX recorded 117 million monthly active users for Grok AI features as of March 2026, out of 550 million total MAUs across Grok and X combined."
