SpaceX’s AI segment reported a $6.355 billion operating loss on $3.201 billion in revenue in 2025, according to its 2026 SEC filing. The segment’s operating loss was 307.1% larger than in 2024. The filing also shows that the loss kept growing in the first half of 2026, even as AI revenue accelerated.

What the reported loss means

The figures are for SpaceX’s AI segment, which incorporates xAI-related operations after the companies’ corporate combination. They are not a standalone xAI cash-flow statement. In particular, an operating loss measures revenue minus operating costs and expenses; it does not, by itself, show how much cash the business used, its total debt, or whether it can meet its obligations.

The figures establish that the AI segment was operating at a substantial loss. They do not establish insolvency, fraud, or when—or whether—it will become profitable.

How much did the AI segment lose?

SpaceX’s 2026 SEC filing reports these annual operating results:

Period Revenue Operating loss What changed
2024 $2.620 billion $1.561 billion —
2025 $3.201 billion $6.355 billion Loss increased by $4.794 billion, or 307.1%, year over year.

In 2025, the operating loss was about 1.99 times revenue, or roughly 199% of revenue. That ratio is calculated from the filing’s reported annual figures; it is not a separate figure reported by SpaceX.

Where the 2025 costs went

The segment reported $9.556 billion in total costs and expenses in 2025. Its expense breakdown was:

2025 expense category Reported amount
Cost of revenue $2.178 billion
Research and development $5.064 billion
Selling and administrative $1.827 billion
Restructuring charges $487 million
Total costs and expenses $9.556 billion

Research and compute infrastructure

Research and development was the largest of these categories. It increased by $3.888 billion, or 330.8%, from 2024. SpaceX attributed the increase to the expansion of AI infrastructure and compute capacity.

That cost pattern helps explain why higher sales did not translate into a smaller annual loss: infrastructure, computing, and research spending expanded sharply as the business built out its capabilities.

Did faster revenue growth narrow the loss in 2026?

Not in the first-half comparison disclosed in SpaceX’s June 2026 filing: the AI segment’s operating loss for the six months ended June 30, 2026, was up 51.5% year over year. The filing does not provide a dollar amount for that comparison in the information cited here, so the percentage should not be treated as an estimate of the full-year 2026 loss.

What changed in Q2

AI revenue in the second quarter of 2026 rose 247.5% year over year. SpaceX attributed $1.600 billion of the increase to AI infrastructure revenue and $258 million to Grok and X subscription revenue. Those are reported contributions to revenue growth, not a breakdown of total quarterly revenue.

Costs rose alongside sales. Compared with the same quarter a year earlier, infrastructure and cloud-computing costs increased by $470 million within cost of revenue, while infrastructure and cloud-computing costs within research and development increased by $726 million. The filing therefore describes fast-growing revenue and materially higher infrastructure costs at the same time; the revenue-growth rate alone does not show that the segment’s overall economics improved.

Can revenue catch up with spending?

The reported results do not establish when revenue might cover costs. The 2025 annual figures show costs and expenses well above revenue, while the first-half 2026 filing reports a larger year-over-year operating loss despite accelerating revenue growth. The Q2 disclosures also show that infrastructure and cloud costs were rising as infrastructure services and Grok/X subscriptions brought in more revenue.

A useful assessment over time would compare operating loss with revenue, absolute infrastructure and compute spending, revenue mix, the loss trajectory across reporting periods, and disclosed funding or debt capacity. The figures cited here provide evidence on the first four areas only in part; they do not give enough information to set a break-even date or measure the segment’s overall financing capacity.
