xAI burned $6.4B last year. SpaceX’s IPO filing shows why the spending is far from over - BERITAJA

Elon Musk’s xAI mislaid $6.4 cardinal from operations connected conscionable $3.2 cardinal successful gross successful 2025, according to SpaceX’s IPO filings. And the losses are poised to grow. SpaceX’s filing reveals plans to standard Grok to “multiple trillions of parameters,” a melodramatic boost that will apt require important further compute spend.

Elon Musk merged his AI institution xAI — which had antecedently acquired his societal media level X (formerly Twitter) — pinch his rocket and outer institution SpaceX successful February earlier announcing that he’d return the mixed institution nationalist this year. While AI competitors OpenAI and Anthropic are besides eyeing nationalist debuts successful 2026, SpaceX’s is expected to beryllium 1 of the largest successful history pinch a imaginable $1.75 trillion valuation. 

The filing marks the first nationalist glimpses into xAI, and truthful X’s, financials. In 2024, xAI recorded a nonaccomplishment of $1.56 cardinal connected $2.62 cardinal successful revenue. By 2025, losses had ballooned to $6.4 cardinal connected $3.2 billion, meaning the spread betwixt what xAI earns and spends is widening. Meanwhile, competitor (and customer) Anthropic reportedly expects a 130% gross jump to $10.9 cardinal successful the 2nd quarter, starring to its first operating profit.

The jump successful gross from 2024 to 2025 came successful ample portion from “AI solutions and infrastructure revenue” totalling $465 million, which includes $365 cardinal successful X and Grok subscription revenue, and $88 cardinal successful information licensing. An further $116 cardinal came from advertising.

AI conception superior expenditures climbed from $12.7 cardinal successful 2025 to $7.7 cardinal successful the first 4th of 2026 alone. That’s an annualized capex tally complaint of about $30.8 billion, much than doubling year-over-year.

So far, that finance has resulted successful growing, but still limited, personification numbers. Per the filing, SpaceX recorded 117 cardinal monthly progressive users for Grok AI features arsenic of March 2026, retired of 550 cardinal full MAUs crossed Grok and X combined. That implies only one-fifth of the mixed ecosystem is actively utilizing Grok AI features. 

Still, SpaceX intends to worker connected pinch Grok; its next-generation AI is expected to standard to “multiple trillions of parameters,” which the filing describes arsenic a “step alteration successful reasoning successful extent and wide intelligence.” It’s an eager target, and 1 that’s now recorded successful the audited annals of SEC history.

It’s besides a target that will undoubtedly require much investment. The SpaceX filing’s “use of proceeds” conception mentions an “expansion of our AI compute infrastructure.” Per the filing, xAI’s Colossus and Colossus II information centers — some of which came online successful 122 days and 91 days, respectively — collectively supply about 1 gigawatt of compute power. These are some utilized for Grok’s training and inference. SpaceX claims that owning the compute infrastructure and vertically integrating crossed the AI stack lets them “train and iterate frontier models astatine little costs and higher velocity.”

Another measurement that SpaceX mightiness assuage investor fears about spending is by performing training and conclusion connected orbital information centers, which Musk has promised to beryllium a overmuch cheaper replacement to terrestrial information centers. That sci-fi imagination isn’t apt to hap for respective years, though. The filing says SpaceX intends to statesman deploying its orbital AI compute satellites arsenic early arsenic 2028 — the first actual timeline group for specified a launch.

“The early of AI will beryllium wished by power of the beingness stack,” the filing reads.
