SpaceX S-1 Filing Reveals Financials, AI Ambitions Ahead of IPO SpaceX’s newly released S-1 lays bare a company losing billions on AI and betting its future on data centers in orbit, even as founder Elon Musk keeps near-total control after the planned IPO.

§Early financial reveals and xAI merger

On May 20, SpaceX opened its books for the first time, reporting $18.67 billion in 2025 revenue but a $4.94 billion loss, driven largely by artificial intelligence spending. The filing followed Musk’s February decision to merge his AI startup xAI — which had already absorbed social network X — into SpaceX, creating a sprawling launch, satellite, social, and AI conglomerate.

The S-1 shows xAI lost $6.4 billion on $3.2 billion in 2025 revenue, with plans to scale its Grok model to “multiple trillions of parameters,” implying even higher compute costs ahead. By early 2026, SpaceX’s AI segment was generating $818 million in quarterly revenue, but remained far from profitable.

§Musk’s control and intertwined empires

As the IPO advances, analysts note the listing “requires a little faith,” with a $28 trillion total addressable market and a valuation target that could make it America’s largest IPO. Musk will retain 85.1% of voting power, and the filing concedes SpaceX is “highly dependent” on him while detailing extensive dealings with Tesla, xAI, X, the Boring Company, and Neuralink — turning Musk himself into a key risk factor.

§The orbital AI bet and environmental backlash

SpaceX claims “we have identified the largest TAM in human history,” projecting $28.5 trillion in future markets, with $26.5 trillion tied to AI compute delivered via orbital data centers. A separate analysis argues the IPO “isn’t really about rockets” but about “orbital AI data centers” — “AI compute satellites” in sun-synchronous orbit starting as soon as 2028.

On the ground, though, xAI’s push for power is already contentious. It is being sued over dozens of unpermitted gas turbines at a Tennessee data center and simultaneously plans to buy $2.8 billion more, a risk SpaceX warns could “adversely affect our AI business” if regulators intervene.

§Competitive and investor perspectives

Rivals are moving on parallel tracks. Google is exploring similar “space-based ML data centers” under Project Suncatcher, reflecting a broader belief that terrestrial infrastructure may not meet exploding AI demand. Anthropic, a SpaceX compute customer, expects Q2 revenue of $10.9 billion and its first operating profit, underscoring how far Musk’s AI unit must travel to catch up.

For now, Starlink remains SpaceX’s only profitable business, carrying most current revenue while Wall Street weighs whether Musk’s sci‑fi‑inflected vision of orbital AI and Mars incentives can justify a trillion‑plus valuation.

[1] Famously secret about its finances, SpaceX opens its books for the first time
“The company reported revenues of $18.67 billion in 2025… [and] projects a ‘total addressable market’… of $28.5 trillion… ‘We believe we have identified the largest TAM in human history.’”

[2] xAI burned $6.4B last year — SpaceX’s IPO filing shows why the spending is far from over
“xAI lost $6.4 billion from operations on just $3.2 billion in revenue in 2025… [and] plans to scale Grok to ‘multiple trillions of parameters’… Elon Musk merged his AI company xAI… with… SpaceX in February.”

[3] SpaceX not the behemoth everyone thought
“SpaceX is wildly unprofitable, reporting a $4.9 billion net loss on $18.67 billion in… revenue for 2025… The Starlink connectivity business… is SpaceX’s only profitable unit and accounted for most of its Q1 revenue… The AI unit containing X and xAI generated only $818 million in Q1 2026.”

[4] SpaceX files to go public, and the math requires a little faith
“The filing runs to 36 pages of risk factors… a $28 trillion total addressable market… and a valuation target that would make it the largest IPO in American history.”

[5] In SpaceX’s IPO, Elon Musk is a risk factor
“The rocket company says it’s ‘highly dependent’ on Musk’s leadership… Based on the Form S-1 filing, Tesla owns nearly 19 million shares… xAI is mentioned 356 times, and X 267 times… further intertwining their fates.”

[6] The most important thing in SpaceX’s IPO sounds completely unhinged
“The real pitch… is something far stranger: orbital AI data centers… ‘AI compute satellites’… starting as early as 2028… move AI infrastructure off Earth and into space, where solar power is effectively unlimited.”

[7] Musk’s xAI is being sued over its data center generators — now it’s buying $2.8B more
“The NAACP filed a lawsuit against xAI… for operating dozens of unregulated gas turbines… xAI will buy another $2.8 billion worth of turbines… SpaceX acknowledges… injunctions or rescinded permits ‘would adversely affect our AI business.’”

[8] How Google plans to win the AI war
“The search giant is trying to win the AI race without cannibalizing its core business” — a strategy that includes exploring ideas like space-based compute alongside its Project Suncatcher work cited in SpaceX coverage.

[9] Anthropic says it’s about to have its first profitable quarter
“Anthropic… will more than double revenue to around $10.9 billion in its second quarter, and deliver an operating profit for the first time… a big milestone… relative to its chief competitor, OpenAI.”
