SpaceX IPO Prospectus in Full: What the Market Is Buying Isn’t Rockets or AI—It’s Musk Himself

The highly anticipated SpaceX has finally filed its IPO prospectus.

This company, which embodies Elon Musk’s vision of 'landing on Mars,' is for the first time laying nearly all its details bare before the public. Driven by curiosity—and a bit of skepticism—I downloaded and read through the original document as soon as it appeared on the SEC’s website on May 20.

I have to say, Musk really delivered—he’s full of sincerity, and the novelty factor is off the charts.

In over two decades of commercial spaceflight, this is the first time a giant of this scale has fully disclosed its financials to the SEC.SpaceX is valued at nearly $400 billion, making it the world’s most valuable private company, and it led the entire industry in rocket launches last year. The market already had a general sense of its scale, but that impression was pieced together from scattered data points—valuation rumors, Starlink subscriber counts, Musk’s ownership stake—and never from a complete, publicly available financial statement.

Even more novel is xAI. While U.S. frontier large-model companies have been under intense spotlight over the past two years, none have submitted comprehensive financial disclosures to the SEC—until now. This time, xAI’s finances and personnel are fully consolidated into SpaceX’s combined financial statements.meaning this IPO prospectus also serves as the first-ever public window into exactly what a cutting-edge large-model company is spending money on—and just how much it’s burning.。

Because of this, I went into the reading with several specific questions already in mind: How big is Starlink’s satellite internet business today? Is the rocket division actually profitable? How aggressively is xAI burning cash? And what’s Musk’s exact ownership stake?

But after reading through it, I realized these seemingly disparate business lines have been intricately woven together by Musk through various financial maneuvers—and the first real test for this behemoth after going public may not be whether market liquidity is sufficient to support fundraising,but rather what valuation framework investors should use to assess it.。

01 Not just rockets

Viewed holistically, SpaceX is not an especially large company—nowhere near the scale of the Magnificent Seven. In 2025, SpaceX reported consolidated revenue of USD 18.7 billion. According to its prospectus, the company’s business is divided into three segments: Space Launch (Space), Satellite Internet (Connectivity), and Artificial Intelligence (AI).

The Space Launch segment includes rockets and spacecraft-related activities: Falcon 9, Falcon Heavy, Dragon spacecraft, Starship development, and government contracts with NASA, the U.S. Space Force’s National Security Space Launch (NSSL) program, and the Department of Defense. The Satellite Internet segment comprises Starlink broadband services and Starshield, a dedicated military satellite offering. The AI segment includes xAI’s Grok large language model, the X platform (formerly Twitter), and two computing centers.

It should be noted thatThe AI business was only integrated into SpaceX in February 2026.Prior to that, xAI had first merged X into its operations in March 2025; then, in February 2026, SpaceX merged xAI in its entirety. Since all three companies were already under Elon Musk’s control, this restructuring qualified as a 'combination under common control' for accounting purposes, requiring the financial statements to retrospectively restate the past three years of historical results.

The clearest illustration is the AI segment’s 2023 results: while it reported external revenue of approximately USD 3 billion that year, the notes to the financial statements reveal that nearly all of this revenue came from X (i.e., Twitter)—specifically from advertising, subscriptions, and data licensing—and had essentially no relation to what we now consider AI-generated revenue.

Of the three segments, only Starlink is profitable. In 2025, the Satellite Internet segment generated an operating profit of USD 4.4 billion, with an operating margin of nearly 39%, contributing the entirety of SpaceX’s operating profit. The Space Launch segment recorded an operating loss of USD 660 million in 2025, while the AI segment posted an operating loss of USD 6.4 billion. The AI segment’s annual operating loss alone far exceeded the Space Launch segment’s total annual revenue of USD 4.1 billion.

When aggregated across all three segments, SpaceX reported an overall operating loss of USD 2.6 billion and a net loss of USD 4.9 billion in 2025. This pattern is not a short-term anomaly: from inception through March 31, 2026, the company’s cumulative deficit—the net shortfall after subtracting cumulative profits from cumulative losses—had reached USD 41.3 billion. Of the past three years, only 2024 recorded a net profit of USD 791 million; 2023 and 2025 saw net losses of USD 4.6 billion and USD 4.9 billion, respectively.

Let’s first examine Starlink, the mature business. It operates nearly 9,600 satellites in orbit—accounting for roughly 75% of all maneuverable satellites globally. Subscribers nearly doubled over the past year, rising from 5 million in Q1 2025 to 10.3 million in Q1 2026. The segment is also actively reducing average revenue per user (ARPU): ARPU declined from USD 91 per month in 2024 to USD 81 in 2025. According to the prospectus, the company explains this by stating,the company prioritizes scale expansion and operational efficiency over increasing ARPU.。

The remaining two business segments are both still burning cash, but in different ways. The losses in the space launch segment primarily stem from Starship. Falcon 9 itself remains profitable, but of its 165 launches in 2025, only 43 were paid launches for external customers—the remaining 122 were dedicated to deploying Starlink’s own satellites. The next-generation Starship is entirely in the investment phase: SpaceX has already poured over $15 billion of its own funds into Starship R&D.However, as of Q1 2026, all Starship flight tests have been classified as internal missions, with no paid payloads ever carried.。

The AI segment’s cash burn is primarily driven by infrastructure investments. In Q1 2026 alone, the AI business incurred $7.7 billion in capital expenditures—more than three times the combined $2.4 billion spent on space launches and satellite internet during the same period.

It’s worth noting that even the brief profitability reported in fiscal year 2024 had nothing to do with core operations. Of the $791 million net profit, $955 million came from unrealized gains on SpaceX’s holdings of 18,712 Bitcoin—a position that hasn’t been touched in three years since it was established—and another $549 million resulted from an accounting-driven tax adjustment based on the company’s projected future earnings, which had no connection to actual business performance.

These two items together totaled $15.04 billion, exceeding the reported net profit for 2024. Excluding them, the company actually posted an operating loss of over $7 billion in 2024. By 2025, both adjustments reversed, dragging consolidated net losses back down to $49 billion.

Overall,Today, SpaceX is a company where ‘Starlink supports all profits while the other two segments burn massive amounts of cash.’ Its only reported profit over the past three years was propped up by Bitcoin unrealized gains and a one-time accounting adjustment.Yet understanding this company requires looking beyond just its business operations: the web of relationships between it and Elon Musk’s other companies is another issue worthy of deeper exploration.

02 The Heart of Musk’s Empire

Elon Musk is an exceptionally talented entrepreneur—so talented, in fact, that many investors barely pay attention to the fundamentals of his companies. To be sure, among his three major business segments—space launch, satellite internet, and AI—there is clear internal synergy between the first two: space launches deliver satellites for Starlink, while Starlink provides consistent launch demand for the launch business. However, the synergy between AI and the other two segments is far more tenuous—so much so that only the vague vision of ‘space-based energy plus computing power’ loosely connects them.

But this kind of ‘tenuousness’ has long been the norm in Musk’s commercial empire.。

From a governance perspective, SpaceX inherently lacks any built-in checks and balances: Elon Musk personally holds 12.3% of the economic interest but controls 85.1% of the voting power on a weighted basis. This ratio means that upon going public, SpaceX will immediately qualify for Nasdaq’s 'controlled company' exemption, relieving it from requirements such as having a majority of independent directors, an independent nominating committee, and an independent compensation committee.

Meanwhile, the prospectus specifically discloses two key points: the company explicitly states it will not purchase key-person life insurance for Musk, meaning it would receive no insurance payout in the event of his death; and the company proactively notes that Musk does not devote all his time and attention to SpaceX—he remains CEO of Tesla and may hold other positions at his discretion.

Betting entirely on Musk alone is the central point of contention for this company after its IPO. Additionally, SpaceX has another distinctive feature: its boundaries with Musk’s other companies are relatively blurred.。

Tesla serves as an example: although it has never directly invested in SpaceX, it is now a shareholder in the company. In January 2026, Tesla committed to investing $2 billion in xAI (in xAI’s Series E funding round). Then, in February, when SpaceX merged with xAI, Tesla’s xAI equity stake was automatically converted into SpaceX Class A shares based on the merger consideration.

The company’s charter also includes a specific corporate opportunity waiver: SpaceX waives certain business opportunities that may be presented to Musk or certain directors, and these individuals have no obligation to offer those opportunities to SpaceX first. If a business opportunity arises simultaneously for both Musk and SpaceX, according to the charter,Musk may legally take that opportunity directly to another company he controls, and SpaceX has no statutory right to be informed of the opportunity first.。

Together, these provisions mean that there is no traditional notion of independence between SpaceX and Musk’s other companies—they form an interconnected network through which capital and business opportunities flow internally.

This interconnectedness introduces significant nuance into valuation. When valuing a typical public company, investors usually start by identifying external, market-based reference points (such as recent M&A offers from peers, per-unit pricing in third-party customer contracts, or discounts in market-driven share placements). However, among the few concrete valuation references disclosed in SpaceX’s prospectus,only one truly qualifies as a 'market price anchor.'。

In September 2025, SpaceX signed a spectrum acquisition agreement with U.S. satellite communications company EchoStar to secure additional spectrum resources for Starlink. The total consideration for this deal was $19.6 billion, of which $11.1 billion was paid in SpaceX’s own Class A shares, priced at $42.40 per share (post-split). Based on the pre-IPO total share count, this implies an implied enterprise valuation slightly above $500 billion—significantly higher than the previously reported private-market estimate of 'close to $400 billion.'

Thus, at this stage, there are roughly three feasible approaches to genuinely valuing SpaceX.

First, directly anchor to EchoStar—the only available reference point. The price of $42.40 per share implies a total valuation of approximately $500 billion, serving as a relatively firm benchmark for the IPO’s initial pricing, even though this figure stems from SpaceX’s private negotiation with EchoStar rather than a public market auction.

Second, apply a sum-of-the-parts (SOTP) approach by valuing each business segment separately. Starlink is now mature and can be valued using multiples typical of consumer internet or telecom service providers; launch services can be benchmarked against traditional aerospace contractors; and the AI business will likely tie back to xAI’s prior private valuation. However, significant internal transactions exist among these segments—such as Falcon 9 launching Starlink satellites and AI operations leasing GPUs through affiliated entities—so summing individual valuations may not yield a more accurate result than valuing SpaceX as a single integrated entity.

Third, abandon the framework used for valuing standalone companies altogether. Instead, view SpaceX as the central node in Elon Musk’s commercial ecosystem—valuing it much like Tesla:What’s being valued is largely Musk’s own execution capability, the capital-raising prowess of his business network, and whether the grand vision of 'Mars colonization plus orbital computing power' can ultimately be realized.。

For now, the market will most likely adopt the third approach as the dominant valuation methodology.

03Conclusion

From PayPal’s sale to eBay, Tesla’s rise from the brink of bankruptcy to becoming the world’s most valuable automaker, SpaceX slashing the cost of human spaceflight by an order of magnitude, to Starlink achieving global coverage in just a few years,this string of achievements—turning science fiction into reality—has given the market a rational basis for betting on Musk.。

Valuing Musk is fundamentally different from valuing an independent company. Even the most challenging corporate valuations still anchor to relatively predictable cash flows and business logic; valuing an individual essentially means assessing Musk’s execution capacity over the next decade, how he allocates his attention, political risks, his health, and even distant, uncertain promises like whether a Mars colony will actually be built.

This is precisely what makes SpaceX’s IPO unique: it brings the task of valuing 'Musk’s commercial network' out of private markets and fully into the public arena for the first time. Going forward, valuing SpaceX will resemble valuing Musk himself. That said, public markets may not be as patient as private investors. If the pace of delivery falls short of expectations, valuation corrections could be far more severe than adjustments based purely on financial performance.

Thus, this IPO is also a new test for Musk himself. $Tesla (TSLA.US)$
