The document Wall Street has been waiting years to read finally landed on May 20, 2026. As Elon Musk's SpaceX races toward what could be the largest IPO in history, its filing delivers a rare mix of hard financial data and bold ambitions of exploring the frontiers of space. The IPO is expected to raise a record $75–$80 billion at a valuation of roughly $1.75 trillion, placing SpaceX among a handful of the world's elite companies and sending ripples across nearly every corner of the equity markets, with listing targeted as early as June 12 on the Nasdaq. Here is everything you need to know — the vision, the revenues, the losses, and the risks — before this historic offering prices.
The Three-Business Empire Inside One Filing
The SpaceX that filed its S-1 is not the rocket company most people picture. It is three distinct businesses bundled into one offering. First, the classic SpaceX launch and space business. Second, Starlink — the satellite internet platform that is the company's true financial engine. Third, xAI — Musk's artificial intelligence company, folded into SpaceX in February 2026 and now the single biggest driver of both spending and losses.
The Starlink business is SpaceX's primary financial engine, accounting for more than two-thirds of revenue and earning $1.2 billion in operating profit in the most recent quarter. The filing details that Starlink generated more than $11 billion in revenue last year. But Starlink's profits are being overwhelmed by the xAI drag. While Starlink generated an operating profit of $1.19 billion in Q1, it wasn't enough to prevent SpaceX from booking a total operating loss of $1.94 billion in the first quarter on $4.69 billion in revenue. The AI segment generated $818 million in revenue but lost $2.5 billion on operations, while spending $7.7 billion on capital expenditures — mostly Nvidia GPUs leased from a company with a SpaceX board member. That related-party dynamic is already raising eyebrows.
The $41.3 Billion Accumulated Deficit
The headline financial figure that every prospective investor must confront is stark. As of March 31, 2026, SpaceX has racked up an accumulated deficit of $41.3 billion, with a $4.27 billion net loss in Q1 of this year alone, compared to $528 million in the year-ago quarter. The filing shows SpaceX directed around 60% of its capital spending in 2025 to its AI division, or around $20 billion — and yet that division lost billions last year and only grew revenue by about 22%, far below the growth rates at frontier AI competitors.
The company recorded spending $3 billion on Starship development in 2025 and $930 million in Q1 2026 alone — a programme that has yet to generate a single dollar of commercial revenue. The filing is frank about the scale of investment required before Starship becomes a commercial product. SpaceX said it expects Starship to begin payload delivery to orbit in the second half of 2026, leaving little room for error — and promising to begin deploying next-generation Starlink V2 satellites via Starship in 2027. For investors who want to read the complete S-1 filing directly from the source, the SEC's EDGAR filing database provides the full registration document in its original form.
Asteroid Mining, Moon Energy, and the $28.5 Trillion TAM
The S-1's vision section reads like science fiction — deliberately so. SpaceX laid out future growth strategies including the lunar economy, manufacturing and energy production on the moon, growing Starlink Mobile, consumer AI platform monetisation, and deploying orbital AI compute at scale. The company identified asteroid mining, in-orbit manufacturing, and energy production on the Moon and Mars as potential future opportunities. SpaceX has a massive estimation of its total addressable market, valuing it at $28.5 trillion — described as "the largest actionable total addressable market in human history" — encompassing $370 billion in space, $1.6 trillion in connectivity, and $26.5 trillion in AI.
These figures are aspirational, not financial projections. The "future markets" section — which mentions in-orbit manufacturing, space tourism, and asteroid mining — describes industries that are currently more works of science fiction than real opportunities, with no obvious timeline for commercial feasibility. But they are relevant to how the company is positioning its valuation narrative for public investors.
The Musk Compensation Package That Requires a Mars Colony
Perhaps the most extraordinary disclosure in the entire filing concerns Elon Musk's new compensation. Among the unusual items in the filing is a grant to Musk in January 2026 of 1 billion performance-based Class B shares. One of the stipulations for the shares to vest is that SpaceX establish a permanent human colony on Mars with at least one million inhabitants. He stands to reap even more shares if the company can create space-based data centres capable of delivering "100 terawatts of compute per year." The new shares, potentially worth an additional $600 billion or more at IPO valuation, only vest if SpaceX hits a market cap milestone of $7.5 trillion — more than four times the current proposed IPO valuation. The compensation structure ties public investor wealth directly to outcomes that have never been achieved in human history.
The Anthropic Contract, the Cursor Option, and Hidden Revenue
The S-1 contains two revenue agreements that received relatively little pre-filing attention but are material. Through its AI infrastructure platform, SpaceX inked a deal for Anthropic to pay it $1.25 billion a month to use compute capacity from its Colossus and Colossus II data centre clusters in Memphis, Tennessee, through May 2029. That single contract — $15 billion per year in locked-in AI revenue — is a powerful argument for the bulls and suggests SpaceX's AI infrastructure play has genuine commercial legs beyond the Grok chatbot. SpaceX has also entered into a deal with Cursor, an AI code-writing programme, that gives it the option to acquire the company for $60 billion or pay a $10 billion termination fee — a strategic position in the AI developer tools market that received no prior public disclosure.
Five Things Every Investor Must Watch
Before committing capital to what is likely to be an intensely hyped offering, investors should focus on five critical variables the S-1 raises but does not fully resolve. First, the xAI drag: can Starlink's margins sustainably subsidise xAI's billions in quarterly losses, or will public shareholders be funding an AI operation with a deteriorating competitive position? Second, Starship's commercial timeline: a second-half 2026 orbital payload delivery schedule has no margin for engineering setbacks. Third, governance: the company is growth-focused and risk is heavily concentrated around Elon Musk, with Class B super-voting shares preserving his control regardless of public shareholder votes. Fourth, the float: Musk has suggested up to 30% of shares could go to retail investors, but the small initial float and large lockup overhang could create significant volatility post-listing. Fifth, the company's total long-term debt at the end of March 2026 was $29.1 billion — a substantial fixed-cost burden in a rising-rate environment. The SpaceX IPO is genuinely historic. Whether it is also a great investment at $1.75 trillion is a question the S-1 raises without fully answering.
