SpaceX IPO: SpaceX filed its S-1 registration statement with SEC on May 20. The stock is set to begin trading on the Nasdaq under the ticker SPCX on June 12, 2026. After more than two decades as a private company, Elon Musk’s rocket and satellite business is finally opening its books to the public. Here is what the filing actually reveals.
Size of the deal
SpaceX is targeting a valuation of roughly $2 trillion on listing day. At that number, it would rank behind only Apple and Nvidia among all publicly traded companies. The IPO is expected to raise around $75 billion, which would eclipse Saudi Aramco’s $29 billion raise in 2019 and become the largest public offering in history.
Twenty-one banks are underwriting the deal, with Goldman Sachs in the lead position. One notable feature: retail investors are allocated 30% of the float. That is three times the standard allocation for a mega-cap IPO. Whether that reflects genuine democratization or a marketing decision to build public hype is worth questioning.

The valuation has moved sharply in a short time. In July 2025, secondary shares traded at $212 each implying a $400 billion valuation. By December 2025, price had risen to around $421 per share, pushing the implied valuation to roughly $800 billion. The current $2 trillion target more than doubles that figure within six months. Investors should ask what has fundamentally changed to justify that acceleration, beyond market excitement.
Revenue: The real story is Starlink
SpaceX reported total revenue of $18.7 billion for 2025 up 33% from $14.1 billion in 2024. In first quarter of 2026, revenue came in at $4.69 billion though growth slowed to 15% year-over-year. The deceleration is notable and is not prominently featured in company’s marketing narrative.
The business breaks into three segments: Connectivity (Starlink), Space (rocket launches), AI (the recently acquired xAI business).
Starlink is carrying the company. The segment generated $11.4 billion in revenue for 2025 representing 61% of total revenue and growing 50% year-over-year. Operating income from Connectivity reached $4.4 billion for 2025 with adjusted EBITDA of $7.2 billion. In Q1 2026, Starlink added $3.26 billion revenue. $1.19 billion was operating income. As of March 31, 2026, the service had 10.3 million subscribers and over 9,600 satellites deployed in low Earth orbit, making it the largest active satellite constellation ever operated.
The rocket launch business, the original core of SpaceX, is a money-loser. Space segment generated $4.1 billion in revenue in 2025. But it posted operating loss of $657 million. In Q1 2026, it lost another $662 million on just $619 million in revenue. Starship development is expensive. And launches are not yet generating enough revenue to cover those costs.
The xAI acquisition: Expensive and unproven
In February 2026, SpaceX completed its acquisition of xAI. It is Elon Musk’s artificial intelligence company. The deal folded Grok and the Colossus data centers into SpaceX, creating a new AI segment now branded SpaceXAI.
The numbers here are stark. AI segment lost $6.36 billion in 2025. In Q1 2026, it posted $818 million in revenue against a $2.47 billion operating loss. Research and development costs within segment rose more than 300% in 2025 driven largely by GPU depreciation and cloud infrastructure costs. The company has $25.45 billion in contractual commitments related to cloud capacity, with 95% of that falling due in 2026 and 2027.
One headline contract: Anthropic agreed to pay $1.25 billion per month for access to SpaceX-linked data center capacity through May 2029. If that deal holds, it could materially accelerate AI segment revenue in the second half of 2026. But a single client accounting for the bulk of a segment’s revenue is a concentration risk, not a strength.
The broader question is whether the xAI merger serves SpaceX shareholders or Musk’s broader portfolio of interests. Shareholders are buying into the combined entity with no practical ability to separate the two businesses.
Losses and the GAAP reality
SpaceX’s adjusted EBITDA for 2025 was $6.6 billion, a figure the company has highlighted. But on a GAAP basis, the company reported a net loss of $4.94 billion for 2025. The gap is explained by stock-based compensation, satellite constellation depreciation, AI infrastructure capital expenditure. These are real costs regardless of how they are classified.
Operating loss widened to $1.94 billion in Q1 2026 driven heavily by $10.1 billion in capital expenditure during that quarter alone primarily on Starship and AI data centers. Losses are growing faster than revenue in the near term. The accumulated deficit on the balance sheet stands at $41.3 billion.
Investors are being asked to value a company at $2 trillion that has never reported a GAAP profit, is in an aggressive spending phase, and has operating losses widening each quarter. That is not unusual for high-growth technology companies. But the valuation multiple leaves almost no room for execution risk.
Governance: You are not getting a vote
The S-1 confirms a dual-class share structure. Class A shares, which are the shares being sold to the public, carry one vote each. Class B shares, held by Musk, carry ten votes each. After IPO, Musk will retain approximately 42% of equity. But he will control around 85% of voting power.
This structure means that public shareholders have no practical ability to influence board composition, executive compensation, strategic direction, related-party transactions. Antonio Gracias, CEO of Valor Equity Partners and SpaceX board member, owned 503.4 million Class A shares heading into IPO. Valor has extensive business relationships with SpaceX subsidiaries, including equipment leases tied to xAI valued at over $20 billion.
Buying SPCX is a bet on Musk’s judgment and priorities. It is not participation in corporate governance. Investors who are uncomfortable with that arrangement should be clear-eyed about it before they purchase shares.
What justifies the valuation
SpaceX claims in its S-1 that its total addressable market is $28.5 trillion. That figure includes global internet access, satellite communications, AI compute, space logistics, and eventual planetary colonization. Some of those markets are real. Others are decades away from generating meaningful revenue.
The credible bull case rests on Starlink. It is a genuinely dominant business in satellite internet, with 50% revenue growth, expanding margins, and a global subscriber base that is still early in its penetration curve. The Falcon 9 rocket has established launch cadence and customer relationships that competitors have not matched.
Starship, if it achieves full reusability at scale, would dramatically lower the cost of orbital access and create a platform for the company’s broader ambitions. SpaceX says the IPO proceeds will fund an “insane flight rate” for Starship, AI data centers in space, and a lunar base. The company plans to begin deploying orbital AI compute satellites as early as 2028.
The bear case is straightforward. The company arrives at a $2 trillion valuation with widening GAAP losses, an expensive and unproven AI bet, founder governance that gives public investors no real recourse, and a thin float relative to total market cap. Starlink’s growth will eventually plateau. Starship’s development timeline has slipped before. And the public market is being asked to price in decades of optionality at a premium that leaves little cushion.
