We finally have the numbers.
After 24 years operating in the shadows of private markets, SpaceX filed its IPO prospectus this week. The S-1 document offers the most detailed financial picture of Elon Musk’s rocket company to date. And the picture is complicated.
The company seeks to raise $80 billion at a $1.7 trillion valuation. That’s more than triple the previous IPO record held by Saudi Aramco, which raised $26 billion in 2019.
But here’s what the filing actually shows: rapid revenue growth paired with mounting losses.
The Revenue Story Hides the Profit Problem
SpaceX generated $18.674 billion in revenue for 2025, up more than 30% from the prior year. For the three months ended March 31, 2026, revenue hit $4.694 billion on a consolidated basis.
The growth looks impressive until you examine the bottom line.
The company recorded a $2.589 billion loss from operations in 2025. In the first quarter of 2026, that loss reached $1.943 billion. Since 2023, SpaceX has accumulated $13 billion in losses.
The filing shows adjusted EBITDA of $6.584 billion for 2025 and $1.127 billion for Q1 2026. But adjusted EBITDA tells a different story than operating losses, and investors will need to understand what sits between those two numbers.
Starlink Carries the Financial Load
One business unit stands out in the filing: Starlink accounts for more than two-thirds of total revenue.
The satellite internet service earned $1.2 billion in profit in the most recent quarter. As of March 31, 2026, Starlink operated approximately 9,600 satellites across low-Earth orbit, serving 10.3 million subscribers in 164 countries and territories.
SpaceX has launched more than 80% of all mass to orbit globally each year since 2023. That’s roughly 7,400 metric tons, with a mission success rate above 99% across its Falcon rockets.
Without Starlink’s profitability, the consolidated losses would look far worse. The rocket business itself appears to be burning cash while Starlink generates it.
The Valuation Defies Market Comparables
At $1.75 trillion against estimated 2025 revenue of $18.5 billion, SpaceX would trade at approximately 95x trailing revenue at the IPO price.
No established public market comparable exists for a company at this scale trading at that multiple.
The enterprise value to EBITDA multiple tells a similar story. At $1.25 trillion valuation against 2025 adjusted EBITDA, SpaceX trades at 156x EBITDA. Compare that to aerospace and defense companies at 13.81x EBITDA, internet services at 14.56x, and the broader tech sector at 21.42x.
You’re either buying into a vision that transcends traditional valuation metrics, or you’re paying a premium that assumes flawless execution for decades.
The xAI Burden Weighs Heavy
Buried in the filing is a financial reality that many investors may overlook: xAI’s losses deepened to $6.4 billion in 2025.
While Starlink more than doubled its profit to $4.4 billion, xAI pulled the consolidated results into negative territory. The company swung to a $4.9 billion loss last year as xAI’s expenses accelerated.
SpaceX plans to begin deploying data centers in space as early as 2028. The company is seeking regulatory approval from the Federal Communications Commission to launch up to 1 million satellites that would function as a data center network supporting AI projects.
The filing treats xAI as part of the consolidated entity, which means investors are buying into both the rocket business and an AI infrastructure play with unclear economics.
Musk’s Control Structure Leaves No Room for Influence
Elon Musk owns 93.6% of SpaceX’s Class B stock. Each Class B share carries 10 votes. That gives Musk 85.1% of voting power.
The filing includes an unusual provision: a grant to Musk in January of 1 billion performance-based Class B shares. One stipulation for those shares to vest requires SpaceX to establish a permanent human colony on Mars with at least one million inhabitants.
Public shareholders will have virtually no say in company direction. You’re investing in Musk’s vision with no ability to influence strategy, capital allocation, or governance.
What This Filing Actually Means
This marks the most important private-to-public disclosure in years. After operating in secrecy since 2002, SpaceX is opening its books to regulatory scrutiny and public analysis.
The filing will face immediate examination on three fronts: Starlink’s margin structure, the financial treatment of xAI integration, and retail allocation mechanics.
We’re watching a company transition from the opacity of private markets to the transparency requirements of public ownership. The price of admission to public markets used to include increased accountability to a dispersed shareholder base.
But this filing suggests a different model: public capital without public influence.
The numbers are now visible. What investors do with them will determine whether this $1.7 trillion valuation represents visionary pricing or speculative excess.
