xAI burned $6.4B last year. SpaceX’s IPO filing shows why the spending is far from over
4B last year. 2 billion in revenue, according to financial disclosures embedded in SpaceX’s IPO filing. The numbers, made public for the first time, reveal a widening gap between spending and earnings as Musk pushes to scale his Grok AI model to unprecedented size.
The numbers behind the losses SpaceX’s filing with the SEC offers the first detailed look at xAI’s finances, and the picture is one of aggressive investment. 62 billion in revenue. 2 billion.
The filing attributes much of the revenue growth to “AI solutions and infrastructure revenue,” which totaled $465 million in 2025, including $365 million from X and Grok subscriptions and $88 million from data licensing. Advertising contributed an additional $116 million. Capital expenditures tell an even starker story.
8 billion, more than double the previous year. The spending is directed largely at compute infrastructure, including xAI’s Colossus and Colossus II data centers, which together provide about 1 gigawatt of computing power. ” But the near-term cost of that strategy is enormous, and the filing does not project when xAI might become profitable.
Orbital data centers: a long-term bet Musk has previously suggested that moving AI training and inference to orbital data centers could dramatically reduce costs. The filing now provides a concrete timeline: SpaceX intends to begin deploying orbital AI compute satellites as early as 2028. “The future of AI will be determined by control of the physical stack,” the filing states.
That vision, however, remains years from reality and would require overcoming significant technical and regulatory hurdles. User adoption remains limited Despite the heavy investment, Grok’s user base remains relatively small. As of March 2026, SpaceX recorded 117 million monthly active users for Grok AI features, out of 550 million total MAUs across Grok and X combined.
That means only about one-fifth of the combined ecosystem is actively using the AI features. 9 billion in the second quarter of 2026, leading to its first operating profit. 75 trillion.
But the filing makes clear that the combined company — SpaceX, xAI, and X — will continue to burn cash at an accelerating rate. Investors will need to weigh Musk’s long-term vision against the immediate financial reality. The filing provides audited numbers that give the market a factual basis for that assessment, but the path to profitability remains uncertain.
Conclusion The SpaceX IPO filing offers an unprecedented window into the finances of xAI and Musk’s broader AI ambitions. The numbers show a company spending heavily to build frontier AI infrastructure, with losses growing faster than revenue. Whether that bet pays off will depend on Grok’s ability to attract users and generate revenue at scale — and on whether orbital data centers can deliver on their promise of lower costs.
For now, the spending is far from over. FAQs Q1: How much did xAI lose in 2025? 2 billion in revenue, according to SpaceX’s IPO filing.
Q2: What is SpaceX’s plan for Grok AI? A: SpaceX intends to scale Grok to “multiple trillions of parameters,” requiring significant additional compute investment, and plans to begin deploying orbital AI compute satellites as early as 2028. Q3: How many people use Grok?
A: As of March 2026, Grok AI features had 117 million monthly active users out of 550 million total MAUs across Grok and X combined. 4B last year. SpaceX’s IPO filing shows why the spending is far from over first appeared on BitcoinWorld .
