The largest IPO in history values SpaceX at roughly 94 times its 2025 revenue. An economic look at what the company actually does, how it got here, and whether the price tag rests on fundamentals or future stories.

On June 12, 2026, SpaceX sold 555.56 million Class A shares at USD 135 each, raising USD 75 billion in its Nasdaq debut under the ticker SPCX. The pricing valued the company at USD 1.77 trillion at the open. After underwriters exercised the greenshoe, total proceeds rose to roughly USD 86 billion (The Motley Fool, 2026). Shares closed the first day at USD 160.95, up 19.2 percent, lifting the market capitalization above USD 2.1 trillion and surpassing the previous IPO record of USD 29.4 billion set by Saudi Aramco in 2019 (The Eastern Herald, 2026).

The IPO is the largest in stock-market history by both gross proceeds and post-listing market capitalization. It also makes founder Elon Musk the first individual whose paper net worth crossed USD 1 trillion (The New York Times, 2026).

The headline numbers are settled. The harder question is whether the price tag rests on what SpaceX has built or on what investors believe it will build. The S-1 prospectus filed on May 20, 2026, gives the first audited public window into the company’s finances and provides the data needed to assess both sides of that question (CGTN, 2026).

What SpaceX actually does

The post-IPO SpaceX operates three reporting segments that share infrastructure but serve very different markets.

Connectivity (Starlink) is the satellite-internet business. It served 10.3 million subscribers across 164 countries as of March 31, 2026, a 105 percent year-over-year increase. The constellation contains roughly 9,600 active satellites. The segment generated USD 11.39 billion in 2025 revenue, up about 50 percent year over year, and USD 4.42 billion in operating income at a 38.6 percent operating margin (CNBC, 2026; SpaceX Chart, 2026).

Space covers the Falcon 9, Falcon Heavy, and Starship rocket programs. The segment generated USD 4.09 billion in 2025 revenue. SpaceX flew 170 launches in 2025, of which 165 were Falcon-family missions and 5 were Starship development flights. About 122 of those launches deployed Starlink satellites, meaning roughly 74 percent of the launch business by mission count served internal customers rather than external paying ones (Belleville News-Democrat, 2026). Despite that scale, the Space segment posted an operating loss of USD 657 million in 2025, largely because Starship development consumed roughly USD 3 billion (TheStreet, 2026).

SpaceXAI is the artificial intelligence segment created when SpaceX absorbed Musk’s xAI and the X social platform in February 2026. It generated USD 3.20 billion in 2025 revenue while posting a USD 6.36 billion operating loss. Capital expenditures for the AI segment reached USD 12.73 billion in 2025, which exceeded the combined capital spending of the launch business (USD 3.83 billion) and Starlink (USD 4.18 billion). In the first quarter of 2026 alone, AI capex totaled USD 7.72 billion (TechFlow, 2026).

Consolidated 2025 revenue was USD 18.67 billion, up from USD 14.0 billion in 2024 and USD 10.4 billion in 2023, a three-year compound growth rate of roughly 34 percent (ZAR Market Trends, 2026). The full-year 2025 operating loss was USD 2.59 billion, and the net loss was USD 4.94 billion. The accumulated deficit at the end of March 2026 stood at USD 41.3 billion, and long-term debt was USD 29.1 billion (FX Leaders, 2026).

The meteoric rise

SpaceX was founded in 2002 and reached profitability for the first time in 2024, posting a USD 791 million net profit on USD 14.0 billion in revenue. The following year, after absorbing xAI and ramping Starship and AI infrastructure spending, the company swung to a USD 4.9 billion net loss on USD 18.7 billion in revenue (Business Standard, 2026).

Three operational milestones explain how a company that has flown rockets since 2008 became the world’s largest IPO in 2026.

First, launch dominance. SpaceX flew 165 Falcon launches in 2025, more than every other launch provider on the planet combined by a margin of 34 percent (Intellectia AI, 2026). Falcon 9 alone has flown more than 620 missions since 2010 with a success rate above 99 percent. The most-flown booster has completed 34 successful missions, an unprecedented level of reusability in orbital launch (MEXC, 2026).

Second, Starlink scale. Subscribers grew from 2.3 million at the end of 2023 to 4.4 million in 2024, 8.9 million in 2025, and 10.3 million by the end of the first quarter of 2026, a 4.5 times increase in roughly two years. Connectivity revenue grew from USD 2.73 billion in 2023 to USD 11.4 billion in 2025 (StockMKTNewz citing SpaceX S-1, 2026).

Third, the AI pivot. By folding xAI into SpaceX, Musk reframed the company as space, connectivity, and AI infrastructure rather than as a launch business alone. The most concrete piece of that pivot is disclosed in the S-1. Anthropic agreed to pay SpaceX USD 1.25 billion per month for compute capacity at the Colossus 1 and Colossus 2 data centers in Memphis, Tennessee. The contract runs through May 2029, for a total value of approximately USD 45 billion (HotHardware, 2026).

The case for the valuation

At USD 1.77 trillion against USD 18.7 billion in 2025 revenue, SpaceX trades at a price-to-sales ratio of roughly 94. Bulls argue that ratio compares the wrong companies. The bull case rests on five points that the S-1 supports.

Near-monopoly economics in launch. SpaceX accounted for roughly 87 percent of all United States orbital launches in 2025 and approximately 83 percent of global orbital payload mass (36Kr, 2026). Falcon 9 captured about 90 percent of global commercial orbital launches the same year (MEXC, 2026). Reusable boosters give the company a structural cost advantage that competitors have not matched at scale, and the moat compounds with every launch cadence improvement.

Starlink as a high-margin subscription business. The connectivity segment carries a 38.6 percent operating margin and a 63 percent adjusted EBITDA margin, generating roughly USD 7.17 billion in segment EBITDA on USD 11.4 billion of revenue (Sacra, 2026). Independent analyst firm Payload forecasts Starlink revenue will grow about 80 percent in 2026 to USD 18.7 billion, which alone would equal the entire company’s 2025 revenue (TechFlow, 2026).

Anchored AI revenue. The Anthropic compute contract delivers approximately USD 15 billion per year in disclosed enterprise AI revenue, enough by itself to nearly double SpaceX’s 2025 standalone revenue. Combined with growing Starlink subscriptions, that contract adds a layer of contracted backlog that did not exist a year ago (Benzinga, 2026).

A scarce-asset premium. SpaceX is the only public-market vehicle that combines orbital launch, satellite broadband, and AI compute infrastructure under one corporate roof. There is no direct comparable, which forces investors who want exposure to space or to private AI infrastructure to buy SPCX directly. That scarcity arguably justifies some premium over multi-product technology peers (Investing.com, 2026).

Optionality on Starship and global mobile broadband. Starship, once operational at design payload, is intended to deploy the larger V3 Starlink satellites that Falcon 9 cannot carry at their planned size. That would unlock the Direct-to-Cell business and meaningfully expand the addressable subscriber base. Bulls argue that even partial execution on Starship and V3 satellites would compress today’s revenue multiple within a few years (CNBC, 2026).

The case against

The bear case is equally documented in the same S-1.

The valuation multiple is unprecedented. At 94 times trailing revenue, SpaceX trades at roughly 4 times the multiple of Nvidia (about 22 times), 6.5 times Tesla (about 14 times), and 25 times Amazon (about 4 times) (The Wall Street Journal, 2026; New Market Pitch, 2026). The valuation also exceeds the multiples of pure-play space companies Rocket Lab and Planet Labs, which trade at lower multiples despite faster percentage revenue growth (Yahoo Finance, 2026).

Losses are widening, not narrowing. The company swung from a USD 791 million profit in 2024 to a USD 4.94 billion net loss in 2025, then posted a USD 4.28 billion net loss in the first quarter of 2026 alone. At that pace, full-year 2026 losses could exceed all of 2025 in a single year (CleanTechnica, 2026). The accumulated deficit stood at USD 41.3 billion at the end of March 2026.

Starlink ARPU is falling. Average monthly revenue per user dropped from USD 99 in 2023 to USD 81 in 2025 to USD 66 in the first quarter of 2026 as Starlink expanded into lower-income markets and offered cheaper service tiers. Subscriber growth remains strong, but unit economics are weakening at the same time. If the trend continues, future Starlink revenue per net new subscriber will be materially lower than the cohorts already onboard (Broadband Breakfast, 2026).

The Anthropic contract has a 90-day termination clause. The S-1 discloses that either party can cancel the USD 45 billion compute agreement on 90 days’ notice. Pricing that revenue at the same multiple as a long-tenor consumer subscription assumes durability the contract does not provide. Anthropic, which Bloomberg reported was raising a USD 30 billion round at a USD 900 billion valuation in May 2026, has parallel multi-billion dollar commitments to Amazon Web Services and Google, so concentration risk runs in both directions (Cort via LinkedIn, 2026).

Governance constrains shareholders. Musk holds approximately 85 percent of voting power post-IPO through a dual-class share structure. That exceeds Mark Zuckerberg’s 61 percent at Meta and Warren Buffett’s 35 percent at Berkshire Hathaway (Mashinii, 2026). New York City Comptroller Brad Lander, New York State Comptroller Thomas DiNapoli, and CalPERS jointly raised concerns in a June 11, 2026 letter that the board separately approved performance grants that could deliver Musk up to 260 million additional super-voting shares tied to USD 7.5 trillion valuation milestones and a million-person Mars colony. The letter argued these compensation structures create conflicts with Musk’s parallel Tesla performance package and reduce minority shareholder leverage (NYC Comptroller, 2026).

The total addressable market story rests on AI. SpaceX cites a USD 28.5 trillion TAM, of which approximately USD 26.5 trillion, or 93 percent, is artificial intelligence. The Starlink TAM is USD 1.6 trillion and the broader space-enabled solutions TAM is USD 370 billion. Investors are largely paying for the AI portion (The Philadelphia Inquirer, 2026). New Constructs CEO David Trainer, citing the math required to justify the valuation, calculated that SpaceX would need to reach roughly USD 1.1 trillion in annual revenue and USD 248 billion in net profit to deliver an ordinary return on a USD 1.75 trillion entry price. For comparison, Amazon’s trailing revenue is approximately USD 743 billion and Alphabet’s trailing profit is approximately USD 160 billion (Fortune, 2026).

A historical comparison

Large IPOs have a mixed record once the listing-day enthusiasm fades. Saudi Aramco priced its 2019 IPO at the equivalent of roughly USD 8.53 per share and traded near USD 7.49 as of mid-June 2026, modestly below its initial price after seven years (Investing.com, 2026). Alibaba, the previous IPO size leader before Aramco, raised USD 25 billion in 2014 and traded above its IPO price for years before underperforming during the 2021 to 2024 period. Facebook, now Meta, traded below its IPO price for more than a year after its 2012 debut before becoming one of the better-performing post-IPO stocks of the decade.

The pattern is that listing-day performance is a weak predictor of long-term return. SpaceX’s first-day pop of 19.2 percent is not unusual for a high-profile listing. What matters more is whether the company can deliver the revenue growth and margin expansion implied by a 94 times sales multiple over a multi-year horizon.

The relevant precedent is closer to high-multiple growth stories than to industrial IPOs. Most of these resolved one of two ways. Either revenue and earnings caught up to the multiple within five to seven years, or the multiple compressed sharply as investors reset expectations. Both outcomes can produce attractive long-term returns, but they require very different time horizons.

Two cyclical pieces of context

SpaceX listed into a market that is itself testing valuation tolerance. The Federal Reserve held the federal funds rate at 3.50 percent to 3.75 percent on June 17, 2026, with median projections now indicating at least one rate hike before year-end. May 2026 headline consumer price inflation was 4.2 percent, the highest reading since April 2023 (CNBC, 2026). Higher discount rates compress the present value of long-duration cash flows, which is exactly the category SpaceX’s valuation depends on.

The IPO market is also concentrated. Goldman Sachs has forecast that 2026 IPO proceeds could reach USD 160 billion, driven by a pipeline that includes both OpenAI and Anthropic alongside SpaceX (The Straits Times, 2026). If those subsequent listings come at similar multiples, the market is telling investors that scarcity premiums for AI-adjacent platforms are sustainable. If they price more conservatively, SpaceX’s listing-day multiple may be a peak rather than a baseline.

The market took less than 20 minutes on June 12 to push SpaceX past a USD 2 trillion valuation. The harder market test will be whether the underlying revenue arrives quickly enough to make that number look reasonable in retrospect.
