SpaceX is preparing for its initial public offering with a staggering valuation of $1.75 trillion. The planned $75 billion capital raise would set a new global record for an IPO.
Retail investors are lining up, institutions are scrambling for allocations, and ETFs are poised for inclusion. Everyone is eager to buy in, with Wall Street seemingly caught in a collective "mission to Mars" euphoria.
However, a critical question remains largely unaddressed: Where exactly will this $75 billion be spent?
After a thorough review of SpaceX's IPO prospectus, it becomes clear the document contains several significant, interconnected risks. While none may be fatal in isolation, their combined effect could significantly shake the $1.75 trillion valuation.
Here is a breakdown of the six primary concerns identified within the filing.
The First Risk: A $20 Billion "Debt Cleanse"
A notable disclosure in the prospectus reveals that approximately 27% of the IPO proceeds—roughly $20 billion—will be used to repay bridge loans associated with the consolidation of xAI and X (formerly known as Twitter).
This represents over a quarter of the total funds raised. In essence, for every share of SpaceX purchased, a quarter of the capital directly addresses the personal debts of its founder.
This move is less about corporate financing and more akin to a bailout. The funds from the 2022 acquisition of Twitter and the subsequent launch of xAI created substantial liabilities. With X's advertising revenue declining and xAI requiring massive GPU cluster investments, both entities face negative cash flow.
The solution appears to be packaging these debts into the SpaceX IPO, effectively using global investor capital to address challenges within other parts of the founder's business empire. While the prospectus terms this a "strategic financial integration," it could be viewed as a form of related-party transaction, where investors in a space company see their capital flow to social media and AI ventures.
The Second Risk: A Stepped Unlock Schedule for Early Investors
While the founder has pledged not to sell shares for 366 days, the prospectus outlines a different set of rules for nearly 50% of the shares held by early venture capital investors. These shares are subject to a unique "stepped performance-based unlock" mechanism.
This means 20% of these shares become eligible for sale after the first quarterly earnings report (around four months post-IPO). An additional 10% can be unlocked early if the stock price rises 30% above the offering price.
In effect, early investors could potentially sell 30% of their holdings within six months, provided the company's performance holds. Given that these early investors likely have a cost basis around $20 per share, compared to an expected IPO price above $500, they are sitting on potential gains of 25-fold.
This structure, more lenient than typical tech IPOs, essentially provides early backers with a "withdrawal card," allowing them to realize profits sooner if the stock performs well.
The Third Risk: Starlink's Declining User Revenue
Starlink is the cash flow engine for SpaceX, contributing over 60% of the company's revenue. However, a key metric is showing signs of strain: the Average Revenue Per User (ARPU).
From $99 in early 2023, Starlink's ARPU has fallen to $66 by the third quarter of 2024—a one-third drop in a year and a half. This decline is driven by market expansion. As growth in high-paying markets like North America and Europe slows, Starlink is expanding into lower-income regions like India and Africa, where user growth is faster but monthly fees are significantly lower.
The result is rising user numbers but falling revenue per user. Concurrently, gross margins have compressed from 45% in 2023 to 38% in 2024. This trend directly challenges the valuation assumptions for Starlink, which is estimated at around $650 billion within SpaceX's sum-of-the-parts model. That valuation hinges on sustained growth in connected households, a premise weakened if ARPU continues to fall.
The Fourth Risk: A Portfolio of 18,712 Bitcoin
SpaceX's balance sheet holds 18,712 Bitcoin, a detail that could introduce significant volatility into its financial statements.
Under accounting rules, digital assets are measured at fair value, with price fluctuations flowing directly into the profit and loss statement. Given Bitcoin's volatility—ranging between approximately $42,000 and $95,000 in 2024—the value of this holding could swing by nearly $10 billion in a single quarter.
With SpaceX's projected annual net profit for 2024 estimated between $3 and $4 billion, Bitcoin's price movements could potentially erase a quarter of its earnings. This creates an unusual situation where the financial performance of a space company becomes partially dependent on cryptocurrency market trends, adding noise to any valuation model.
The Fifth Risk: Environmental Liabilities of the Falcon 9
SpaceX's workhorse rocket, the Falcon 9, is the world's most frequently launched vehicle. However, environmental data in the prospectus notes that each Falcon 9 launch emits approximately 5 tons of black carbon (soot) directly into the stratosphere.
Research from the U.S. National Oceanic and Atmospheric Administration (NOAA) indicates black carbon in the stratosphere has a warming effect up to 540 times greater than at ground level. NOAA is currently studying the impact of commercial rocket launches on ozone layer depletion.
Should this research conclude that launches cause material damage, regulatory costs could rise sharply. While SpaceX's next-generation Starship vehicle, which uses a cleaner methane-based propellant, is a strategic hedge, it remains in testing. For the next 2-3 years, the Falcon 9 will remain the primary vehicle, with launch frequency increasing. Nearly 100 annual launches could inject 500 tons of black carbon into the stratosphere, potentially inviting restrictive regulations that could impact Starlink deployment and defense contracts.
The Sixth Risk: SpaceX as a Financial Conduit
The final, overarching risk ties the previous five together. SpaceX, X, and xAI are forming a deeply interconnected financial loop.
SpaceX's IPO funds may repay debts at X and xAI. X's advertising revenue could subsidize xAI's computing costs. xAI's technological outputs may bolster the AI narrative for SpaceX. While framed as synergy, it resembles using capital from one entity to support an entire business empire.
Compounding this is the founder's controlling stakes: 82.4% voting power in SpaceX, absolute control in xAI, and majority ownership in X. This concentration of power means no external force can check decisions that might prioritize the empire's health over SpaceX's independent interests.
Investing in SpaceX, therefore, may be less an investment in a pure-play space company and more an investment in a key node of a larger, financially intertwined ecosystem whose overall health is currently under pressure.
The $1.75 trillion valuation is not a monolithic certainty. It represents a composite of these six significant risks, each embedded within the prospectus, awaiting scrutiny from investors.
