Elon Musk's space company is about to make history on Wall Street, and the numbers are staggering even by the standards of the current AI boom. SpaceX has set the terms for what is shaping up to be the largest initial public offering ever recorded, and the deal carries an unmistakable artificial-intelligence subplot that has Wall Street arguing about whether the price tag makes any sense at all.
What Happened
According to an amended registration statement filed with the U.S. Securities and Exchange Commission, SpaceX plans to sell 555.6 million Class A shares at a fixed price of $135 each. That single figure does most of the talking: the offering would raise roughly $75 billion and value the company at approximately $1.77 trillion once outstanding shares are folded in. No company has ever raised that much money in a public debut. The stock is expected to begin trading on the Nasdaq under the ticker SPCX, with the listing targeted for the middle of June.

The scale is easier to grasp through comparison. At $1.77 trillion, SpaceX would arrive as roughly the seventh-largest company in the United States, leapfrogging Berkshire Hathaway and edging past Musk's own carmaker, Tesla, which currently trades near a $1.6 trillion market capitalization. The company is also breaking with convention by pricing at a fixed level rather than letting bankers build a range during the roadshow, an unusual move that puts a hard stake in the ground before institutional investors have weighed in.
What is going public, however, is no longer a pure rocket maker. In February 2026, SpaceX absorbed Musk's artificial-intelligence venture xAI in an all-stock transaction, transforming the business into a hybrid of satellite-internet operator and AI conglomerate. The prospectus is candid about where the money is meant to go in the long run: Musk frames the entire enterprise around establishing a self-sustaining city on Mars, with the rockets serving as transport and the AI serving as the system that would organize such a colony. The near-term reality is more grounded, and considerably more complicated.
Why It Matters
The headline valuation rests on two very different engines bolted together. Starlink, the satellite-internet network, is the profitable half: it generated about $11.39 billion in revenue in 2025 and throws off healthy operating margins. xAI, the home of the Grok chatbot, is the cash-burning half. The structure of the deal essentially asks public investors to let Starlink's profits subsidize an AI buildout whose returns remain unproven.

That tension matters because it mirrors the central question hanging over the entire AI industry in 2026. Investors have poured record sums into frontier-model companies on the promise of eventual dominance, and the SpaceX listing forces that bet into the open in a way private rounds never did. Public markets demand disclosure, and the S-1 lays bare just how expensive the AI ambition has become. The filing shows that more than three-quarters of the proceeds are already committed elsewhere, pledged to repay debt held by Valor Equity Partners, X Corp, and former xAI investors, and to pay EchoStar for a spectrum acquisition. By some estimates that leaves under $18 billion of fresh capital actually available for the AI compute expansion the company is selling.
There is also a governance dimension that sophisticated buyers are watching closely. Musk would hold roughly 82.4% of the voting power after the offering, enough to seat or remove a majority of the board on his own and to classify SpaceX as a "controlled company" exempt from certain Nasdaq governance requirements. With only about 4% of the company floating to the public, index funds tracking the Nasdaq 100 would be forced to buy shares mechanically once the stock qualifies for inclusion, a dynamic that hands early backers a guaranteed exit while leaving new shareholders with little influence.
The Reaction
Wall Street's response has been notably skeptical for a deal of this magnitude. The research firm Morningstar pegged SpaceX's fair value at roughly $780 billion, less than half the asking price, and wrote bluntly that the company "has been significantly overvalued." Analysts there argued that patient investors would likely find better entry points after the initial trading frenzy fades.

The math behind the caution is hard to dismiss. At the targeted valuation, SpaceX would trade at roughly 94 times its 2025 revenue of about $18.67 billion, a multiple that, in Morningstar's framing, requires essentially flawless execution from a business that is currently posting net losses. The AI unit is the main drag. In 2025, xAI lost about $6.36 billion on $3.20 billion of revenue, and the bleeding accelerated into 2026: SpaceX reported an operating loss of $1.9 billion in the first quarter, with xAI alone responsible for roughly $2.5 billion of red ink in the same period. Analysts project the AI venture could burn through about $10 billion across 2026.
One Morningstar analyst went further, warning that xAI represents a "material threat of value destruction" and describing its competitive moat against rivals such as OpenAI and Anthropic as "indeterminate." Adding to the unease, all eleven of xAI's original co-founders departed between mid-2024 and early 2026, and Musk himself has publicly acknowledged that the venture was not built correctly the first time and is being rebuilt from its foundations. For a company asking investors to fund an AI moonshot, the talent exodus is an awkward footnote.
What's Next
The SpaceX filing also functions as a starting gun for what bankers are calling a once-in-a-generation IPO summer. Anthropic confidentially filed its own prospectus on June 1, and OpenAI is widely rumored to be preparing a listing of its own. Together these debuts could test whether public markets have the appetite to absorb a wave of trillion-dollar AI-adjacent offerings in quick succession.
Nasdaq has already moved to accommodate the megacap arrivals. The exchange rewrote its rules to let the largest IPOs enter the prestigious Nasdaq 100 index after just 15 trading days rather than waiting months for the usual reconstitution, and it scrapped a longstanding 10% minimum float requirement in the process. SpaceX's unusual lockup terms reinforce the engineered scarcity: instead of a standard 180-day cliff, insiders can begin selling portions of their holdings after the company's first quarterly earnings report, with Musk himself barred from selling for a full 366 days.
For the AI industry specifically, the listing will serve as a live experiment in public-market patience. If SPCX trades well despite xAI's losses, it validates the thesis that investors will tolerate years of spending in pursuit of frontier-model leadership. If it stumbles, it could cool sentiment ahead of the Anthropic and OpenAI debuts and force a broader repricing of AI valuations that have been set almost entirely in private markets until now.
Closing Thoughts
The SpaceX IPO is fascinating precisely because it refuses to be one clean story. It is a rocket company with a genuinely profitable satellite business, wrapped around an AI venture that is losing billions, priced at a level that even bullish observers struggle to justify on current fundamentals. The deal asks investors to underwrite a vision that stretches from low Earth orbit to Mars while accepting a governance structure that concentrates nearly all real control in one person.
However it trades, the listing marks a milestone for how the AI era is being financed. For years the largest model-builders have grown on private capital, shielded from quarterly scrutiny. SpaceX is the first of the trillion-dollar cohort to step into the daylight of public markets, and the verdict that traders deliver in the coming weeks will echo well beyond a single ticker. Whether that verdict reads as conviction or caution, it will tell us something real about how much the market is willing to pay for a future that has not arrived yet.
한글 요약
일론 머스크의 우주기업 스페이스X가 사상 최대 규모의 기업공개(IPO)를 추진합니다. 클래스 A 주식 5억 5,560만 주를 주당 135달러 고정가에 매각해 약 750억 달러를 조달하며, 기업가치는 약 1조 7,700억 달러로 평가됩니다. 나스닥에 'SPCX'로 상장되며 6월 중순 거래 시작이 예상됩니다. 이는 미국 7위권 기업 규모로, 버크셔 해서웨이와 테슬라를 앞지르는 수준입니다.
핵심 쟁점은 인공지능입니다. 스페이스X는 2026년 2월 머스크의 AI 기업 xAI를 전량 주식교환 방식으로 흡수하며 위성인터넷·AI 복합기업으로 변모했습니다. 흑자 사업인 스타링크(2025년 매출 약 113.9억 달러)가 적자 사업인 xAI를 떠받치는 구조입니다. xAI는 2025년 32억 달러 매출에 63.6억 달러 손실을 냈고, 2026년에는 약 100억 달러를 소진할 것으로 전망됩니다. 모닝스타는 적정가치를 약 7,800억 달러로 제시하며 "상당히 고평가됐다"고 지적했습니다.
이번 상장은 'IPO 여름'의 신호탄이기도 합니다. 앤트로픽이 6월 1일 비공개 상장 서류를 제출했고, 오픈AI도 상장 준비설이 돕니다. 나스닥은 대형 IPO를 15거래일 만에 나스닥100 지수에 편입할 수 있도록 규정을 개정했습니다. 스페이스X 주가가 xAI의 손실에도 견조하게 거래된다면 AI 산업에 대한 시장의 인내심이 확인되겠지만, 부진하다면 이후 상장들과 AI 밸류에이션 전반에 영향을 줄 수 있습니다.
