Two days before trading begins, the filings and roadshow paint a clearer picture of the largest public offering in history — and what investors are actually buying.
On Friday, June 12, Space Exploration Technologies Corp. is scheduled to begin trading on Nasdaq under the ticker SPCX. The company plans to raise $75 billion at $135 per share, valuing it at roughly $1.77 trillion.
Saudi Aramco's 2019 listing — until now the largest IPO on record — brought in $29.4 billion. SpaceX would more than double that figure. For an industry built on government contracts and patient private capital, the number is staggering. The more practical question is simpler: what sits inside the prospectus?
The Timeline: From Confidential Filing to Nasdaq
SpaceX filed confidentially with the Securities and Exchange Commission on April 1. The public S-1 followed on May 20 — the first audited financial disclosure in the company's 24-year history, including 36 pages of risk factors.
The roadshow opened June 4. Pricing is set for June 11; first trade June 12.
The calendar moved faster than many expected. Listing had been discussed for late June. Reuters cited sources who attributed the acceleration to a quicker SEC review. Whether that reflects a one-off or a new normal for mega-offerings remains to be seen. What is settled: a 21-bank syndicate led by Morgan Stanley, Goldman Sachs, JPMorgan, Bank of America, and Citigroup did not wait.
On June 3, SpaceX filed an updated prospectus with the share count and price — details absent from the original S-1. That document confirmed 555,555,555 Class A shares at $135, all primary issuance, with underwriters holding a 15% overallotment option worth up to $11.25 billion more.
Three Businesses, One Prospectus
The S-1 splits SpaceX into three segments. The valuation only makes sense once you read them separately.
Connectivity (Starlink) is the profit engine. In 2025 it generated $11.4 billion in revenue, $4.4 billion in operating income, and $7.2 billion in segment-adjusted EBITDA. Subscribers passed 10 million during the roadshow. Starlink is not a side project funding rockets. It is the balance sheet.
Space (launch) posted $4.1 billion in revenue and a $657 million operating loss. Starship alone consumed $3 billion in R&D in 2025. The vehicle completed its 12th test flight in May — the first V3 configuration — but commercial payload revenue remains thin. Payload delivery is expected to ramp in the second half of 2026, with Starlink deployment as the near-term workload.
AI (xAI) is the newest and costliest piece. SpaceX acquired Musk's AI company in an all-stock deal in February 2026, retrospectively recasting prior financials. The segment reported $3.2 billion in revenue and a $6.4 billion operating loss in 2025. Roughly 60% of 2025 capital spending went to AI infrastructure — the Colossus data center, Grok model development, and related compute. The merger also brought X onto the balance sheet and an estimated $530 million in legal exposure the filing flags directly.
Consolidated: $18.7 billion in 2025 revenue and a $4.9 billion net loss. That reverses 2024, when SpaceX alone was reportedly profitable. The xAI merger imported the red ink.
Q1 2026 showed the pattern continuing — $4.7 billion in revenue and a $4.3 billion net loss, with $7.7 billion of $10.1 billion in quarterly capex directed to AI.
The Valuation Debate
At $135 a share and roughly 13.1 billion shares outstanding, SpaceX prices near 95 times trailing revenue and about 27 times adjusted EBITDA. Palantir — often cited as the S&P 500's most expensive name — trades around 62 times sales.
Morningstar's Nicolas Owens has put fair value near $780 billion, implying substantial downside from the IPO price. Other analysts treating the filing as a stress test rather than a celebration have landed in a $1.0–1.2 trillion range once xAI burn rates and Starship timelines are discounted.
The bull case runs differently: Starlink scaling toward $14 billion in 2026 EBITDA at telecom-like multiples, Starship unlocking lower cost-per-kilogram economics, and xAI capturing frontier-model value that private markets already price in the hundreds of billions. Musk's roadshow deck frames AI as a $27 trillion opportunity. Public investors are being asked to underwrite that thesis on day one.
Structure matters too. The IPO sells less than 5% float — all new shares, no insider selling. Scarcity can inflate opening prices independent of fundamentals. Index providers have shortened inclusion timelines; Nasdaq-100 eligibility could arrive as early as mid-July. Passive funds tracking major indexes would then become forced buyers on a schedule that does not wait for quarterly earnings to confirm the multiple.
Governance: A Controlled Company in Orbit
Musk will hold roughly 40% of economic interest but 82.4% of voting power through Class B shares carrying 10 votes each. SpaceX qualifies as a controlled company under Nasdaq rules and does not need a majority-independent board.
"As a result, Mr. Musk will be able to control the outcome of matters requiring shareholder approval," the prospectus states plainly.
He has agreed not to sell his stake for 366 days after listing. Other insiders face a more granular unlock schedule tied to earnings announcements and share-price milestones — some windows opening as early as August if the stock trades 30% above the IPO price.
For investors used to proxy fights and activist pressure, the structure is familiar from other Musk-led entities. It also means minority shareholders have limited leverage if capital allocation favors Mars infrastructure or orbital data centers over near-term returns.
Use of Proceeds
The prospectus offers categories, not line-item budgets:
- Expansion of AI compute infrastructure
- Launch infrastructure and vehicle development
- Satellite constellation scale-up
- General corporate purposes
Net proceeds are estimated at $74.4 billion after expenses, or $85.7 billion if underwriters exercise their full overallotment.
The allocation in practice is already visible. Q1 2026 put $7.7 billion toward AI and $930 million toward Starship in a single quarter. AI first, connectivity second, launch third — even though launch is what built the brand.
The filing also describes ambitions that stretch well beyond quarterly metrics: up to one million orbital data center spacecraft, space-based solar, and the long-standing Mars objective. Public-market discipline will be tested against those goals from the first earnings call onward.
SpaceX entered the process with about $30 billion in debt and $16 billion in cash — a $20 billion bridge loan tied to AI infrastructure matures roughly 15 months after the IPO. The offering improves liquidity. It does not remove the refinancing question.
What to Watch After June 12
The IPO answers one question: how badly investors want access.
The quarters afterward answer the rest:
- Starlink margins — Can subscriber growth continue without eroding the EBITDA that supports the valuation?
- Starship economics — Reusability claims need to become per-launch cost data, not test-flight headlines.
- xAI burn rate — Revenue grew roughly 22% in 2025, well below frontier peers. The gap must narrow or the segment stays a permanent drag.
- Insider lock-up releases — Secondary supply from early employees and investors could pressure the stock regardless of operations.
- Index inclusion — Forced buying from passive funds may decouple the share price from fundamentals for weeks after debut.
Options on SPCX are expected to begin trading June 16.
The Bottom Line
SpaceX's IPO is not really about rockets. Starlink pays the bills. xAI and Starship define the story Musk is selling to public markets.
At $1.77 trillion, investors are paying upfront for outcomes that may take a decade to prove — orbital data centers, Mars logistics, a vertically integrated AI stack operating from Earth and orbit.
The listing will almost certainly succeed as a capital-raising event. Whether it succeeds as an investment depends on whether Starlink's terrestrial cash engine can outrun the burn rate of everything else inside the prospectus.
