SpaceX has filed confidential paperwork with the Securities and Exchange Commission to go public at a valuation that would shatter every record in IPO history. Sources familiar with the filing told Bloomberg and the Associated Press that the company is targeting a roughly $1.75 trillion valuation, with a listing expected as soon as June 2026. If that number holds, SpaceX would debut as one of the ten most valuable public companies on Earth, larger at the opening bell than all but a handful of firms in the S&P 500.
The scale is difficult to overstate. The current record for an IPO belongs to Saudi Aramco, which raised about $25.6 billion when it listed in December 2019. SpaceX, at a $1.75 trillion valuation, is expected to offer stock on a major U.S. exchange with far broader access for institutional and retail investors than Aramco provided on the Saudi exchange. The “10x” comparison refers to the capital raised in the offering itself: if SpaceX sells enough shares at that valuation, the dollars flowing into the deal could exceed Aramco’s $25.6 billion record by roughly an order of magnitude. (Aramco’s total market capitalization at debut was near $1.7 trillion, comparable to SpaceX’s target, but only a tiny sliver of Aramco’s shares actually traded publicly, limiting the size of that IPO as a capital-raising event.)
For the tens of millions of Americans whose retirement savings track the S&P 500, this matters directly. However, a critical caveat: S&P 500 inclusion is not guaranteed. S&P Dow Jones Indices applies specific criteria including cumulative profitability, adequate public float, and sufficient trading history, and the index committee retains full discretion over timing. If SpaceX does eventually meet those criteria and is added to the index, passive funds that mirror the S&P 500 would be required to purchase shares to stay aligned with the benchmark. That would mean SpaceX stock flowing into 401(k) accounts, target-date funds, and IRAs across the country without those account holders ever placing a buy order. But that outcome depends on decisions that have not yet been made.
What the reporting confirms
Two independent reporting chains back the core development. Bloomberg reported in early April 2026 that SpaceX submitted a confidential draft registration statement to the SEC, with sources anticipating a June listing. The Associated Press separately confirmed that SpaceX filed preliminary paperwork to sell shares to the public, a step AP noted is likely to make Elon Musk a trillionaire based on his ownership stake. Neither outlet’s reporting has been independently verified by SpaceX or the SEC, and the linked articles reflect those outlets’ sourcing as of their publication dates.
The confidential route SpaceX is using is well-established. Under the SEC’s expanded nonpublic review procedures, any company can submit draft registration statements for staff review before going public. The trade-off is a hard deadline: SpaceX must publicly file the registration statement, along with all previously submitted drafts, at least 15 days before any investor roadshow begins. That 15-day window is when the rest of the world will see SpaceX’s audited financials, revenue breakdown, and risk disclosures for the first time.
If the June timeline holds, the public S-1 filing and roadshow could arrive as early as late May 2026, compressing the window for analysts to build models and for index committees to begin eligibility reviews.
Why SpaceX, and why now
SpaceX has operated as a private company since its founding in 2002, raising capital through private rounds at progressively higher valuations. The push toward a public listing appears driven by several converging factors.
Starlink, the company’s satellite broadband division, reportedly reached profitability in late 2024, according to reporting from The Wall Street Journal. With more than 4 million subscribers across dozens of countries, Starlink gives SpaceX a recurring revenue story that public-market investors can model, distinct from the lumpier economics of launch contracts. A public listing also provides liquidity for early employees and investors who have held illiquid shares for years, some since the company’s earliest funding rounds.
Then there is the question of Musk himself. His role leading the Department of Government Efficiency (DOGE) under the Trump administration and his deep involvement in political spending have drawn intense public scrutiny. A public SpaceX would subject the company’s government contracts, particularly its billions in NASA and Department of Defense work, to the kind of quarterly disclosure that private status has shielded it from. Whether that transparency helps or hurts the stock is something the market will have to price in.
SpaceX would also be entering a crowded IPO window. Several large private technology companies, including Stripe and Databricks, have been widely expected to go public in 2026. SpaceX’s sheer scale could absorb significant investor capital and attention, potentially reshaping the sequencing and pricing of other high-profile listings.
What remains uncertain
No public copy of the draft registration statement exists yet. The $1.75 trillion valuation and the June target date both come from sources familiar with the filing, not from SpaceX, Musk, or the underwriting banks on the record. Until a finalized S-1 appears on the SEC’s public database, the exact share price, number of shares offered, lock-up terms, and lead underwriters remain unknown. Major Wall Street banks typically compete to lead offerings of this size, but no underwriter has been publicly named in connection with the SpaceX deal. SpaceX has not issued any statement confirming the timeline or the valuation.
The path from confidential filing to trading day is rarely a straight line. SEC staff may request amendments or additional disclosures during the nonpublic review, which can stretch the timeline by weeks or months. Market conditions could shift. SpaceX retains the option to delay or withdraw the filing entirely before it becomes public. The company’s revenue mix between Starlink subscriptions, government launch contracts, and the capital-intensive Starship development program will face intense scrutiny once the S-1 drops, and surprises in those numbers could move final pricing well above or below the reported $1.75 trillion range.
The trillionaire question also carries a significant asterisk. Whether Musk crosses that threshold depends on his exact ownership percentage after any dilution from the IPO itself, from shares set aside for employee stock plans, and from the terms of any secondary offerings. AP’s reporting frames the milestone as likely based on his current stake, but the S-1 will be the first document to reveal how much of the company Musk will actually own once public shares are outstanding. A large enough dilution, or a final valuation below the $1.75 trillion target, could push that milestone further out.
S&P 500 inclusion, while widely expected for a company of this size, is not automatic. S&P Dow Jones Indices applies specific criteria including cumulative profitability, adequate public float, and sufficient trading history. SpaceX is known to favor governance structures that concentrate control with Musk, and if the IPO features a dual-class share setup with limited voting rights for public shareholders, index providers could delay or restrict inclusion. S&P Global announced in 2023 that it would no longer exclude multi-class companies from the S&P 500, reversing a prior ban, but the index committee still retains discretion over timing. That would affect how quickly the stock filters into retirement portfolios.
What investors should actually watch for
When the S-1 goes public, it will contain audited financials, detailed risk factors, the specifics of any dual-class share structure, and the mechanics of insider lock-up periods. Those lock-ups matter: when they expire, typically 90 to 180 days after the IPO, insiders and early investors can sell. In a company with as many long-tenured employees as SpaceX, that selling pressure can be substantial.
Investors should also watch for the competitive landscape disclosures. Blue Origin, backed by Jeff Bezos, has ramped up its own launch cadence and satellite ambitions. United Launch Alliance, a joint venture of Boeing and Lockheed Martin, continues to compete for national security launch contracts. And in the satellite broadband market specifically, Amazon’s Project Kuiper is preparing to deploy thousands of its own internet satellites, creating a direct rival to Starlink’s core growth business.
The SEC’s own investor education resources stress reading the full prospectus before buying into any IPO, understanding lock-up mechanics, and recognizing that early trading in high-profile offerings is often volatile. That advice applies with extra force here. The scale of the SpaceX deal and the expectation of eventual index-fund buying may create a sense of inevitability around the stock. But the underlying risks, from launch failures to regulatory shifts in satellite spectrum allocation to the political entanglements of its founder, will belong to whoever owns the shares.
The confidential filing is real, but the S-1 has not dropped yet
SpaceX has taken a concrete step toward the public markets. The confidential filing is corroborated by multiple credible outlets and consistent with the SEC’s established review framework. But the company has not yet committed to a public S-1, a share price, or a date. The gap between filing confidentially and actually ringing the opening bell is where most of the important information will emerge. Until then, the only document that matters is the one SpaceX has not yet released.
