SpaceX files for record IPO with massive AI bet

SpaceX just pulled back the curtain on its closely guarded financials, officially filing its S-1 prospectus with the SEC to go public on the Nasdaq under the ticker SPCX. What was once Silicon Valley’s ultimate private sandbox is now set for what could be the largest IPO in history, targeting a $1.75 trillion valuation and an unprecedented $75 billion capital raise.

The massive regulatory filing provides our first unfiltered look at Elon Musk’s sprawling rocket, satellite internet, and AI conglomerate.

Starlink pays the bills, while AI burns the cash

According to the prospectus, SpaceX generated $18.67 billion in revenue in 2025. But growth didn't come cheap: the company recorded a net loss of over $4.9 billion last year, with capital expenditures skyrocketing to $20.7 billion, almost doubling from $11.2 billion in 2024. All told, SpaceX has burned more than $37 billion since inception.

The clear cash cow keeping the lights on is Starlink. The space-based broadband network pulled in over $11 billion in 2025, accounting for more than half of the company’s total top line.

Where is all that cash going? Mostly into artificial intelligence and heavy rockets. SpaceX directed roughly 60 percent of its 2025 capital spending — around $20 billion — directly into its AI division, which recently absorbed Musk’s xAI. That bet has yet to see commercial breakout: xAI generated $3.2 billion in revenue last year against a staggering $6.4 billion operating loss, growing its top line by just 22 percent.

Still, xAI brought at least one massive enterprise contract along for the ride. The S-1 reveals that Anthropic is paying SpaceXAI $1.25 billion every month through May 2029 as part of a dedicated compute agreement.

Meanwhile, the company’s physical backbone remains hitched to Starship. R&D spending for the heavy-lift vehicle hit $3 billion in 2025 and added another $930 million in Q1 2026 alone. SpaceX stated it expects Starship to begin payload delivery to orbit in the second half of 2026, aiming to cut orbit access costs by 99 percent relative to historical industry benchmarks.

The $28.5 trillion pitch and absolute control

To justify its astronomical valuation, SpaceX presented public investors with what it claims is the largest actionable total addressable market in human history: a staggering $28.5 trillion.

The math behind that eye-popping figure leans overwhelmingly on AI rather than rocketry. SpaceX allocates just $370 billion to space and $1.6 trillion to Starlink connectivity, while reserving $26.5 trillion for AI, dominated by an estimated $22.7 trillion in enterprise software applications.

The blueprint envisions putting data centers directly into orbit to power AI models with unfiltered solar energy. In January, the company petitioned the FCC to launch one million data center satellites. The filing also revives the futuristic idea of using Starship for point-to-point suborbital passenger and cargo transit across major Earth cities.

Yet, the filing’s 36 pages of risk disclosures paint a much more sobering picture. SpaceX explicitly warned investors that several anticipated markets, including orbital AI and interplanetary transit, are still emerging or do not currently exist at all. Legal fallout from integrating Musk's social media and AI entities is also expected to cost roughly $530 million.

Public shareholders shouldn't expect any governance leverage, either. Musk will retain CEO, CTO, and board chair roles, supported by supervoting shares granting him 85 percent voting control. His board is heavily fortified with loyal insiders, including Tesla director Ira Ehrenpreis and Google executive Donald Harrison.

Why it matters

For retail and institutional investors, SPCX isn't a play on an aerospace pure-play; it is an all-in bet on Elon Musk's personal grand strategy. Starlink is demonstrably a real, profitable utility, but it is now tied at the hip to xAI’s cash-burning engine. Entering at a $1.75 trillion valuation means buying into speculative promises of off-planet computing that won't show real commercial fruit for years.

For the tech and space industries, this filing forces an unprecedented collision between aerospace and hyperscale compute. Legacy defense contractors are already outmatched on launch cadence, and if Starship delivers on its 2026 payload commitments, SpaceX will monopolize global mass-to-orbit capability. Meanwhile, tech giants like Microsoft and Google must face a competitor trying to sidestep Earth’s power and cooling bottlenecks altogether by putting servers into orbit.

In our view, rolling xAI into SpaceX ahead of the IPO was a masterclass in financial engineering, but it comes with immense governance baggage. Musk successfully used Starlink's proven revenues to rescue xAI from venture funding fatigue. However, locking up 85 percent voting control leaves public investors funding extreme moonshots with zero say in operational course corrections. SpaceX is asking Wall Street to underwrite a sci-fi future, and the market is about to discover whether the numbers can actually support the gravity.
