SpaceX Files for the Largest IPO in History — and the Conflicts of Interest Are Staggering

On April 1, 2026, SpaceX submitted a confidential draft registration to the U.S. Securities and Exchange Commission for an initial public offering targeting a $1.75 trillion valuation [1][2]. The company aims to raise approximately $75 billion, which would eclipse Saudi Aramco's $29.4 billion listing in 2019 by a factor of roughly 2.5x [3]. If the offering proceeds as planned, SpaceX would debut on public markets sometime in June 2026 as one of the ten most valuable companies on Earth — more valuable than Walmart, ExxonMobil, or Meta [1].

The scale of the ambition is matched by the scale of the questions it raises. SpaceX is not just a rocket company anymore. Following a February 2026 all-stock merger that absorbed Elon Musk's artificial intelligence venture xAI — valued at $250 billion — into SpaceX's corporate structure, the entity preparing to go public is a conglomerate spanning orbital launch, satellite internet, artificial intelligence, social media, and defense contracting, all controlled by a single individual who also runs Tesla and until recently led a federal cost-cutting body with authority to cancel government contracts [4][5].

The Financial Case: $15 Billion in Revenue, $8 Billion in Profit

SpaceX generated approximately $15 billion in revenue and $8 billion in EBITDA profit in 2025, according to Reuters and The Information [6][7]. That represents roughly a 53% EBITDA margin — a figure that would be exceptional in any industry but is almost unheard of in aerospace.

Starlink, SpaceX's satellite internet constellation, is the dominant revenue engine. Payload Research estimates Starlink subscriptions and hardware sales accounted for $10.4 billion of SpaceX's 2025 revenue, with launch services contributing approximately $3.5 billion [8]. The company completed 165 Falcon 9 missions in 2025, a launch roughly every other day [9].

But the valuation math is demanding. At $1.75 trillion, SpaceX would trade at roughly 117x its 2025 revenue and 219x its EBITDA. For comparison, Boeing trades at approximately 1.5x revenue with a market cap of $192 billion. Lockheed Martin, the largest U.S. defense contractor with a $179 billion backlog, is valued at roughly $150 billion [10]. SpaceX's target valuation would exceed the combined market caps of Boeing, Lockheed Martin, RTX Corp, and Northrop Grumman by more than threefold.

The implied thesis is that SpaceX is not an aerospace company at all but rather a technology platform — and that its growth trajectory will resemble Amazon or Alphabet more than Lockheed or Boeing.

The Starlink Question: How High Can the Revenue Ceiling Go?

The $1.75 trillion valuation is only defensible if Starlink's growth continues at a steep trajectory. As of late 2025, Starlink had surpassed 9 million active subscribers globally [11]. Analysts project that figure could reach 18.4 million by the end of 2026 [12].

Average revenue per user varies significantly by market. Payload Research estimates global ARPU at roughly $70 per month, though residential customers in the U.S. pay considerably more [8]. At 9 million subscribers and ~$70 monthly ARPU, that implies roughly $7.5 billion in annualized subscription revenue, broadly consistent with the reported $10.4 billion figure when hardware sales and enterprise contracts are included.

The bull case sees Starlink reaching 30-50 million subscribers within three to four years, with enterprise, aviation, and maritime segments driving higher ARPU. Analysts estimate Starlink's gross margins reached approximately 25% by 2026, with free cash flow potentially hitting $2 billion in 2025 [12].

The bear case focuses on spectrum constraints. In January 2026, the FCC approved only 7,500 of SpaceX's requested 30,000 second-generation satellites, issuing a partial approval with milestones rather than blanket authorization [13]. More critically, the FCC granted SpaceX only a "time-limited waiver" to exceed spectrum-sharing power limits, contingent on the outcome of a rulemaking process initiated in April 2025 [14]. Competitors including traditional geostationary satellite operators have been actively challenging Starlink's spectrum access, and the waiver contains what analysts describe as a "kill switch" clause requiring cessation of operations if harmful interference is proven [14].

Internationally, the spectrum environment is even more contested. In late December 2025, Chinese entities filed ITU submissions covering more than 200,000 satellites, establishing coordination claims over the orbital and spectrum resources that Starlink depends on [15].

Government Dependency: $22 Billion in Federal Contracts

SpaceX has received approximately $22 billion in cumulative federal contracts, with NASA accounting for roughly $13 billion and the Department of Defense approximately $5 billion [16]. Defense contracts doubled from $856 million in 2023 to $1.8 billion in 2024 [16]. The Pentagon is reportedly preparing a $2 billion contract for a 600-satellite missile-tracking constellation [5].

This government dependency creates disclosure complications for a public company. SpaceX serves as NASA's primary crew launch provider for the International Space Station and holds over $4 billion in Artemis lunar program contracts [5]. The company has become, in effect, critical national security infrastructure — which means an S-1 filing will need to navigate the tension between investor transparency and classified program sensitivities.

The conflict-of-interest dimension compounds the problem. Musk was the largest individual donor to President Trump's 2024 campaign and subsequently led the Department of Government Efficiency (DOGE), a temporary body that cancelled more than 10,000 federal contracts [5][17]. Ethics observers noted that none of those cancellations affected Musk's own companies [5]. Donald Trump Jr. holds SpaceX shares through 1789 Capital, a venture fund that invested approximately $50 million in SpaceX and xAI and has backed at least four companies that subsequently received government contracts during the current administration [5].

These entanglements will appear in SpaceX's risk factors and related-party disclosures. Whether the current SEC — which has reportedly been in settlement talks with Musk over prior securities law disputes — will scrutinize them aggressively is an open question [17].

Governance: One Man, 79% of the Vote

SpaceX is considering a dual-class share structure for the IPO that would grant Musk super-voting rights of 10-20 votes per share, similar to structures at Alphabet and Meta [18][19]. Musk currently holds approximately 42-43% of SpaceX's equity but controls roughly 78-79% of voting power through the existing private dual-class structure [20].

This is not unusual among founder-led tech companies. Mark Zuckerberg controls approximately 58% of Meta's voting power with roughly 13% economic ownership. Larry Page and Sergey Brin retain majority voting control of Alphabet. But those companies faced sustained shareholder backlash over governance — Meta shareholders have repeatedly proposed eliminating the dual-class structure, and proxy advisory firms routinely flag these arrangements as governance risks [18].

The SpaceX case is arguably more acute because of the breadth of Musk's obligations. He simultaneously serves as CEO of Tesla (a $900+ billion public company), controls xAI (now folded into SpaceX), owns X (the social media platform), and until recently held a formal advisory role in the federal government. Tesla shareholders are currently suing Musk over Tesla's $2 billion investment in xAI, arguing he directed public shareholder capital into his own private venture [5][17].

SpaceX plans to allocate up to 30% of shares to retail investors — roughly three times the typical IPO allocation [1][4]. Critics view this as a strategy to build a base of loyal individual shareholders less likely to challenge management through proxy votes or governance proposals [5].

The xAI Merger: Bailout or Strategic Masterstroke?

The February 2026 merger between SpaceX and xAI looms over the IPO filing. The all-stock deal valued SpaceX at $1 trillion and xAI at $250 billion, creating a combined entity worth $1.25 trillion [1]. All 11 original xAI co-founders have since departed the combined company [5].

Critics characterize the merger as a financial bailout. xAI was reportedly burning approximately $1 billion per month at the time of the deal, and folding it into SpaceX's cash-generating Starlink division provided a lifeline [5]. Musk controlled both buyer and seller, raising self-dealing concerns that mirror the Tesla-SolarCity acquisition litigation that took years to resolve.

Supporters counter that integrating AI capabilities directly into SpaceX's operations — from autonomous rocket landing to satellite constellation management to defense applications — creates genuine strategic value. The combined entity, they argue, is better positioned to compete for the growing market in AI-powered defense and intelligence contracts.

The SEC will need to determine whether the merger's terms were fair to shareholders on both sides, and the prospectus will need to disclose the basis for the valuations assigned to each entity.

Who Benefits: Private Gains vs. Public Risk

SpaceX's valuation trajectory illustrates a broader trend in capital markets: the migration of value creation from public to private markets. The company was valued at $46 billion in August 2020. By December 2024, that had risen to $350 billion through a secondary share sale. A July 2025 tender offer valued it at $400 billion. By December 2025, it had reached $800 billion [21][22].

SpaceX conducts biannual tender offers that allow employees and existing shareholders to sell stock, but these are typically restricted to accredited or institutional investors through platforms like Forge Global and Nasdaq Private Market [21]. Retail investors have been almost entirely locked out of SpaceX's private growth phase.

Research from MVP Ventures analyzing unicorn IPOs between 2019 and 2025 found that companies showed median annual appreciation of 65.7% between reaching $1 billion valuation and their IPO date [23]. Investors who bought at the IPO offer price realized median returns of 39.8%, but those who bought at the first-day opening price saw returns of just 1.6%, and those who purchased at the first-day close experienced median returns of -1.4% [23].

The pattern is clear: the further from the private phase an investor enters, the worse the expected returns. For SpaceX, this suggests that the $1.75 trillion IPO pricing — representing a 38x increase from the 2020 valuation — may leave limited upside for public market participants.

As Fortune columnist Jeffrey Stewart argued, "Much of the benefit that once accrued to public investors is now captured in private markets." He noted that Amazon went public in 1997 at approximately $438 million, allowing public investors to participate in virtually the entire value creation arc. SpaceX's public investors will be entering at a point where the company is already one of the most valuable private entities in history [24].

The Case Against Going Public

The strongest argument against a SpaceX IPO comes not from financial skeptics but from space industry advocates who worry about what public market pressures will do to the company's long-duration bets.

SpaceX's identity is built on missions that have no clear near-term financial return: colonizing Mars, making humanity multi-planetary, building a fully reusable super-heavy-lift launch system in Starship. These are projects measured in decades, not quarters.

"If SpaceX does go public then that completely kills all Starship development for the Mars dream," electronics engineer and commentator Dave Jones wrote on X. "No shareholder is going to vote to continue that" [25].

Analysts at SpaceNews observed that the IPO pricing "becomes a bet on Elon Musk's team's ability to deliver new products and services that either don't exist or might not be foreseeable," noting the valuation is "unusually dependent on unproven opportunities even given SpaceX's strong track record" [26].

The counter-argument is that Musk's dual-class share structure exists precisely to insulate these long-term bets from short-term shareholder pressure — that public investors are buying into Musk's vision, not buying the right to redirect it. But this creates a paradox: investors are being asked to pay a $1.75 trillion price for a vision they'll have no power to shape.

Regulatory Gauntlet

Even if investor demand materializes, SpaceX faces a regulatory gauntlet. The SEC must review the S-1 for completeness and accuracy, and the related-party disclosures alone — covering the xAI merger, Musk's cross-company roles, government contracts, and political connections — will be extensive [17].

Musk's history of public statements that skirt securities law adds another complication. The SEC is reportedly preparing to settle a dispute over Musk's alleged 2022 securities law violations, and regulators have previously expressed concern about his social media posts affecting market prices [17]. During the "quiet period" between filing and listing, Musk will be constrained in what he can say publicly — a restriction that sits uneasily with his prolific posting habits.

S&P Global and Nasdaq have recently updated their index inclusion rules in ways that could fast-track SpaceX for major index membership despite its dual-class structure [27]. If SpaceX enters the S&P 500 or Nasdaq-100 shortly after listing, index funds would be forced buyers — creating a significant demand floor but also raising questions about whether passive investors are being compelled to own a company with governance arrangements many institutions would otherwise reject.

What Happens Next

SpaceX's confidential filing starts a clock. The company will work with the SEC to revise the S-1, and the public filing — which will contain the first official look at SpaceX's finances — could appear weeks before the targeted June listing. Underwriters have not been officially named, but reports suggest Goldman Sachs, Morgan Stanley, and Bank of America are competing for lead roles [1].

The outcome will set precedents that extend well beyond SpaceX. If a company can go public at $1.75 trillion with a single individual controlling nearly 80% of votes, dependent on government contracts managed by political allies, having just merged with a money-losing AI company controlled by the same person — and the market embraces it — that will tell us something fundamental about the state of American capital markets, regulatory oversight, and the concentration of corporate power in 2026.
