SpaceX is preparing to go public at a valuation that dwarfs anything Wall Street has ever seen. The rocket and satellite company founded by Elon Musk has confidentially submitted a draft IPO registration statement to the U.S. Securities and Exchange Commission, Bloomberg reported in April, citing people familiar with the matter. The company is targeting a June 2026 listing at a valuation of roughly $1.75 trillion, and its public prospectus is expected to land as soon as next week. When it does, it will crack open SpaceX’s books for the first time in the company’s 24-year history.
The scale is almost difficult to process. The largest U.S. IPO by company valuation was Meta Platforms, which went public at about $104 billion in 2012. Saudi Aramco’s 2019 listing in Riyadh reached approximately $1.7 trillion in market capitalization, but that deal floated only about 1.5% of shares on the Saudi stock exchange and raised roughly $25.6 billion in proceeds, making it the largest IPO ever by capital raised. SpaceX’s anticipated $1.75 trillion valuation at listing would surpass even Aramco’s debut market cap, but the two figures measure different things: valuation at listing reflects the implied worth of the entire company, while offering size refers to the capital actually raised by selling new or existing shares. No American company has ever approached the public markets at anything resembling the valuation SpaceX is now reportedly pursuing. At $1.75 trillion, SpaceX would debut larger than all but a handful of companies currently trading on any exchange worldwide, placing it in the neighborhood of Amazon and Alphabet.
How the confidential filing process works
SpaceX is using a legal pathway that has become routine for companies heading toward a public listing. Since 2017, the SEC has allowed all companies to submit draft registration statements confidentially, giving issuers a chance to receive staff feedback, revise disclosures, and resolve comment letters before the market sees anything. Hundreds of companies have taken this route. What makes SpaceX’s filing extraordinary is not the process but the sheer magnitude of what is moving through it.
The key deadline to understand: under SEC rules, an issuer must publicly file its registration statement, including all prior confidential drafts and amendments, at least 15 days before beginning a road show with institutional investors. If SpaceX plans to start meeting fund managers by late May or early June 2026, a public filing in the coming days fits that window. That arithmetic is why market participants expect SpaceX’s S-1 to appear on the SEC’s EDGAR database within the week.
What remains unconfirmed
No public EDGAR record of SpaceX’s submission exists yet, and that is by design. Confidential filings do not surface until the company elects to make them public or is required to do so ahead of a road show. The only confirmation comes from Bloomberg’s unnamed sources. SpaceX has not commented, and the SEC does not discuss confidential submissions.
The $1.75 trillion valuation is similarly unanchored to any disclosed financial data. SpaceX has never published audited revenue, operating margins, or cash flow statements. Private secondary-market transactions have traced a steep upward curve: the company was valued at roughly $100 billion in early 2021, around $180 billion by mid-2024, and reportedly north of $350 billion by late that year, according to tender offer data tracked by platforms like Forge Global and reported by PitchBook. But the leap from $350 billion to $1.75 trillion is a fivefold jump in roughly 18 months, and prospective investors will have no way to evaluate whether it is justified until the S-1, with its required audited financials, becomes available.
The June 2026 target is also a projection, not a locked date. IPO timelines shift based on SEC review cycles, market conditions, and issuer readiness. If the public prospectus has not appeared by mid-May, a June road show becomes arithmetically difficult under the 15-day rule.
The business SpaceX is actually selling
SpaceX’s valuation rests on two major business lines with no close public-market equivalent operating at the same scale.
The first is its launch division, anchored by the Falcon 9 rocket, which has become the dominant vehicle in the global commercial launch market. SpaceX conducted more than 130 orbital launches in 2025, far outpacing any government agency or private competitor, according to publicly tracked mission manifests. Its next-generation Starship, the largest and most powerful rocket ever built, is in active flight testing and central to NASA’s Artemis lunar landing program as well as the company’s long-stated Mars ambitions.
The second, and increasingly important, revenue driver is Starlink, SpaceX’s satellite internet constellation. By early 2026, Starlink had surpassed 5 million subscribers across more than 100 countries, a figure Musk shared on his social media platform X but that has not been independently audited. Starlink’s recurring subscription revenue and expanding enterprise and government contracts have led some Wall Street analysts to estimate the division alone could be worth well north of $100 billion. The S-1 will reveal, for the first time, how much of SpaceX’s total revenue comes from Starlink versus launch services and what the margin profile of each segment looks like.
Then there are the questions the prospectus will need to address that go beyond revenue lines. SpaceX holds billions of dollars in contracts with NASA and the U.S. Department of Defense, making government exposure a significant risk factor. Musk’s simultaneous roles as CEO of Tesla, chairman of xAI, and owner of X raise governance questions about management bandwidth and potential conflicts of interest. His prominent advisory role in the current presidential administration adds another layer of complexity: investors will want to understand how SpaceX’s federal contracting relationships intersect with Musk’s political proximity to the White House. Previous reports have suggested SpaceX considered spinning Starlink off as a separate public company; the S-1 should clarify whether that option remains on the table or has been folded into a unified listing.
What a $1.75 trillion debut would do to the market
A SpaceX IPO at anything close to that figure would absorb enormous institutional capital and reset valuation benchmarks across the space-technology and defense sectors. For competitors planning their own capital raises or public listings in 2026, the timing is critical. A mega-offering of this size could crowd out investor attention and wallet share, forcing smaller issuers to delay or accept lower valuations. On the other hand, a successful SpaceX debut could serve as a catalyst that reopens an IPO window largely shut since 2021 for large venture-backed companies.
Regulators and exchange operators will be watching just as closely. A listing of this magnitude will test the capacity of underwriters to allocate shares fairly, the resilience of exchange trading systems on opening day, and the adequacy of current disclosure rules for a company that has operated in near-total financial secrecy for over two decades. Bloomberg and other outlets have reported that Goldman Sachs and Morgan Stanley are expected to lead the offering, though the underwriter lineup has not been formally confirmed. Any post-IPO volatility or price dislocations could feed into ongoing debates in Washington over whether the confidential filing process, originally designed for smaller issuers, needs additional guardrails when used by companies of this size.
The one document that changes everything
The single most important near-term event is the appearance of SpaceX’s S-1 registration statement on the SEC’s EDGAR system. That document will contain audited financial statements, a breakdown of revenue by segment, details on capital expenditure plans, a description of the share structure (including any dual-class voting arrangement that could entrench founder control), and the specific terms of the offering: how many shares will be sold and at what price range.
Until that filing goes live, Bloomberg’s reporting stands as a high-confidence signal from credible sourcing, but deal-specific details remain unconfirmed. The regulatory framework governing the process is settled and publicly documented. The company’s actual finances, its precise valuation, and its timeline are not. As of late May 2026, the most anticipated IPO in a generation has not yet crossed into the public record. But across Wall Street trading desks, Pentagon procurement offices, and retail brokerage apps, the planning has already begun.
