The SpaceX IPO

SpaceX recently filed paperwork to go public on the Nasdaq, targeting a valuation between $1.75 trillion and $2.0 trillion. After reading the initial sections of the filing and comparing it to independent analysis by NYU Stern professor Aswath Damodaran, I have concluded that SpaceX is best understood as three distinct businesses operating under a single corporate structure. These are the Starlink connectivity division, the space launch and Starship development division, and the artificial intelligence division formed by the merger with xAI. Each division has fundamentally different financial characteristics, and understanding them is essential to evaluating the IPO.

Starlink is currently the only profitable segment. The company reports over 10 million subscribers across more than 160 countries, with annual revenue exceeding $11 billion and operating income in the billions. The division’s profit margins are remarkably high. In contrast, the space launch division generates significant revenue but posts operating losses due to heavy research and development spending on the Starship program. The artificial intelligence division, which was absorbed through an all‑stock merger, has incurred billions in losses and its capital expenditures routinely exceed those of the other two divisions combined. Consequently, while SpaceX was profitable in the recent past, it recorded substantial net losses after the merger. Starlink serves as the financial engine; the other divisions are deliberate loss‑makers designed to fund long‑term bets on space transportation and AI infrastructure.

The valuation gap between Damodaran’s independent discounted cash flow analysis and the IPO target is significant. Damodaran values SpaceX at approximately $1.22 trillion, with Starlink accounting for the majority of that value, followed by the launch business, the AI division, and expansion options such as space travel. He projects revenue growing from roughly $15 billion currently to hundreds of billions a decade from now, with operating margins approaching 50 percent. At the IPO target of $1.75 trillion, however, he has stated that he would not buy. He would consider entry closer to $1 trillion to provide a margin of safety. The roughly $500 billion premium that the market is being asked to pay represents a bet on what the filing describes as orbital AI computing, the idea that SpaceX will deploy AI data center satellites in the near future and build a vertically integrated platform spanning launch, connectivity, and AI infrastructure.

What makes SpaceX structurally unique is its control of the entire value chain. The company manufactures the vast majority of its rocket components in‑house. Engine costs have fallen dramatically, and launch costs per mission have dropped from hundreds of millions to roughly $30 million. SpaceX produces thousands of Starlink satellites each year and launches them on its own rockets at near‑zero marginal launch cost. Competitors such as Amazon’s Kuiper project have committed tens of billions of dollars but rely on third‑party launch providers, which introduces costs that SpaceX has eliminated. This structural advantage is not merely a first‑mover advantage; it is a coordination advantage that competitors cannot easily replicate without first solving the same manufacturing, launch, and operational challenges.

The filing also makes an ambitious claim about total addressable market, placing the figure at nearly $30 trillion, which is roughly the size of the entire United States economy. The vast majority of this claimed market comes from artificial intelligence applications and infrastructure, while the businesses that currently generate revenue, connectivity and space launch, represent a small fraction of the total. While such market estimates in IPO filings are typically optimistic, this particular projection is clearly aspirational. It signals that the company is asking investors to pay for a future that does not yet exist in its financial statements.

Finally, there is a mechanical factor that will affect many ordinary investors through their retirement accounts. The Nasdaq recently approved new rules that allow a large IPO to be added to the Nasdaq 100 index as little as 15 trading days after listing. If SpaceX lists in June as planned, it could enter the index by early July. When this happens, every index fund that tracks the Nasdaq 100 must purchase shares to maintain correct weighting. Estimates of forced buying range from billions to tens of billions of dollars when including derivatives and actively managed funds benchmarked to the index. This is not a discretionary investment decision; it is a mechanical requirement. The risk is that lock‑up periods for insiders typically expire several months after the IPO, at which point large shareholders holding the majority of shares may sell into the inflated passive demand. Inclusion in the S&P 500 would follow later and could absorb even more of the public float.

In conclusion, SpaceX is three companies combined into one: Starlink, the profitable cash engine; the space division, the strategic reinvestment vehicle; and xAI, the capital‑intensive option on AI infrastructure. At a $1.75 trillion valuation, investors are not paying for the company’s current financial performance. They are paying for a future in which launch, connectivity, and AI converge under a single owner that controls the critical bottleneck. Whether that future arrives is uncertain. What is certain is that passive index flows may force many investors to buy the story before it has been tested in public markets.
