Elon Musk’s xAI lost $6.4 billion on $3.2 billion in revenue last year, and the spending spree is just getting started. According to TechCrunch AI, SpaceX’s IPO filing offers the first audited look inside xAI’s books since Musk merged the AI startup with his rocket company in February. The numbers are brutal, but the roadmap is even more aggressive.
The losses are accelerating. In 2024, xAI was down $1.56 billion on $2.62 billion in revenue. By 2025, that gap had ballooned, with losses more than quadrupling while revenue grew just 22%. TechCrunch AI reports that AI segment capital expenditures hit $12.7 billion in 2025, then jumped to $7.7 billion in Q1 2026 alone, an annualized run rate near $30.8 billion. That’s more than double year-over-year.
Where the Money’s Coming From
The $3.2 billion in 2025 revenue breaks down across a few buckets:
- $365 million from X and Grok subscriptions
- $88 million from data licensing
- $116 million from advertising
- The rest from broader AI solutions and infrastructure deals
For context, Anthropic is reportedly heading toward $10.9 billion in Q2 revenue and its first operating profit. xAI is burning roughly $2 for every $1 it brings in. Anthropic is about to flip green.
The Grok User Problem
Here’s what stands out: Grok has 117 million monthly active users for its AI features as of March 2026, out of 550 million combined MAUs across Grok and X. Only one-fifth of the ecosystem actually touches the AI. That’s a tough ratio when you’re spending $30 billion a year on compute to power it.
What the Filing Promises
The filing locks in some ambitious targets that are now part of SEC record:
- Next-gen Grok scaling to “multiple trillions of parameters,” described as a step change in reasoning depth
- Colossus and Colossus II data centers already providing roughly 1 gigawatt of compute, built in 122 and 91 days respectively
- Orbital AI compute satellites beginning deployment as early as 2028, the first concrete timeline Musk has put on his space-based data center pitch
The vertical integration argument is that owning the full stack lets xAI train and iterate frontier models cheaper and faster than competitors renting from hyperscalers. That’s the bet investors are being asked to underwrite.
Why This Matters
SpaceX is heading for what could be a $1.75 trillion IPO, one of the largest in history, with OpenAI and Anthropic also lining up public debuts in 2026. The xAI numbers are now the price tag attached to Musk’s AI ambitions, and they’re going on the prospectus.
What’s significant here is the framing. The filing reads: “The future of AI will be determined by control of the physical stack.” That’s xAI staking out a position that compute ownership, data center buildouts, and eventually orbital infrastructure are the real moat. Not the model. Not the product. The physical layer.
For practitioners and operators watching this space, a few things to track:
- Whether Grok’s MAU share of the X ecosystem grows past 21% as a signal that the product is finding traction
- How fast capex compounds against revenue growth, because the current trajectory isn’t sustainable without massive top-line acceleration
- The 2028 orbital data center timeline, which would be a genuine industry first if it ships
The IPO will force discipline on numbers that have been private until now. Public market scrutiny tends to sharpen things. More details at the original source.
