SpaceX’s long-awaited IPO filing pulls back the curtain on a wildly ambitious, money-losing company that wants to dominate both spaceflight and artificial intelligence — and asks investors to take a leap of faith on markets that mostly don’t exist yet.

From secretive unicorn to public candidate

On May 20, SpaceX opened its books for the first time, revealing $18.67 billion in 2025 revenue but a $4.94 billion loss, largely driven by spending on AI after acquiring Elon Musk’s xAI and social platform X earlier this year.¹ The S‑1 lists a total addressable market of $28.5 trillion, almost all of it tied to data and AI rather than rockets or Starlink.¹

Subsequent analyses underscored how dependent the IPO case is on future growth. Axios noted that SpaceX is “wildly unprofitable,” with a $4.9 billion 2025 net loss and an AI unit that generated just $818 million in Q1 2026.² TechCrunch summarized the pitch as math that “requires a little faith,” tied to a TAM “that would make it the largest IPO in American history.”³

AI bets, orbital data centers, and legal risks

The filing shows xAI lost $6.4 billion on $3.2 billion in 2025 revenue and plans to scale its Grok model to “multiple trillions of parameters,” driving capital expenditures toward an annualized AI capex run rate above $30 billion.⁴ Another Business Insider analysis argued the IPO is “about Elon Musk's plan to build AI data centers in orbit,” with “AI compute satellites” targeted for launch as early as 2028.⁵

Yet the AI expansion is already contentious. Business Insider reports that SpaceX warns investors that Grok’s NSFW features pose “heightened risks” including “potential nonconsensual or exploitative imagery” and has already triggered multiple lawsuits and investigations.⁶ TechCrunch notes xAI is being sued over polluting gas turbines at a Tennessee data center even as it commits to buy $2.8 billion more, a strategy SpaceX itself says could face injunctive risk.⁷

Grand visions vs. skepticism

SpaceX’s own prospectus language reads “like a sci‑fi manifesto,” outlining bets on “orbital AI compute,” a future space economy on the Moon and Mars, and other “future markets” it concedes do not yet exist.⁸⁹ Ars Technica and other outlets highlight the company’s claim that it has “the largest TAM in human history,” with AI compute as “our next trillion-dollar market.”¹

Critics question those numbers. One economist quoted by Axios called the $28.5 trillion estimate “farcical,” even allowing for the fuzziness of TAM calculations.¹⁰ Financial advisers told Axios retail investors should avoid buying into the IPO at all, warning these mega-cap AI offerings are likely “already priced to perfection” and historically underperform broad indexes.¹¹

Others focus on contradictions in Musk’s energy narrative. TechCrunch and The Next Web point out that xAI’s gas-fired data centers and SpaceX’s emphasis on space-based solar sit uneasily beside Tesla’s long-promised “solar electric economy,” now largely sidelined in the filing.¹²¹³

Musk’s framing

Musk, for his part, uses X to celebrate Starship’s progress — “Starship Rising” and a “goal for humanity” — and to amplify praise for SpaceX’s “incredible” team and its role in making humanity multi‑planetary.Elon Musk (elonmusk)¹⁴Elon Musk (elonmusk)¹⁵ His posts echo the S‑1’s core message: that investors aren’t just buying into a launch company, but into an audacious bet that AI compute in space, lunar bases, and Martian industry can someday justify one of the richest valuations in market history.
