SpaceX IPO: The AI Infrastructure Play Behind SPCX (2026)

SpaceX began trading on Nasdaq today, June 12, 2026, under the ticker SPCX after pricing the largest IPO in history — a roughly $75 billion raise at $135 per share. But the most important story for the tech world isn't the rocket business. It's that the company going public is, on paper, one of the world's largest AI infrastructure providers.

TL;DR

• SpaceX priced its IPO at a fixed $135 per share on June 11, selling about 555.6 million Class A shares to raise roughly $75 billion at a valuation of approximately $1.77 trillion — trading opened on Nasdaq today under SPCX.¹²
• It is the largest IPO in history by proceeds, more than 2.5 times Saudi Aramco's record (its 2019 listing reached $29.4 billion after the greenshoe was exercised in January 2020) and about triple Alibaba's $25 billion (its post-greenshoe total), the biggest U.S. IPO until now.¹³⁴
• SpaceX absorbed xAI on February 2, 2026 in an all-stock deal valuing the combined company at $1.25 trillion — bringing Grok, X, and the Colossus data center complex in Memphis under the SpaceX umbrella.⁵
• The S-1 revealed two blockbuster AI compute deals: Anthropic pays $1.25 billion per month through May 2029 for the entire output of Colossus 1, and Google will pay $920 million per month for 32 months starting October 2026.⁶⁷
• The catch: Elon Musk retains 85.1% of voting power through a dual-class share structure, making SPCX one of the most founder-controlled mega-caps ever listed.⁸

The Largest IPO in History: SpaceX by the Numbers

The SpaceX IPO is the largest initial public offering ever by proceeds. The company sold approximately 555.6 million Class A shares at a fixed price of $135 each, raising roughly $75 billion, with underwriters holding an option to purchase about 83.33 million additional shares that could add roughly $11.2 billion more.¹² CNBC reported the offering valued the company at approximately $1.77 trillion.²

For context: SpaceX raised more in one offering than Saudi Aramco and Alibaba raised combined — and it did so while reporting a net loss. That only makes sense if investors are pricing in something beyond rockets and satellites.

How the SpaceX xAI Merger Created an AI Infrastructure Giant

The SpaceX xAI merger closed on February 2, 2026. It was an all-stock transaction that made xAI a wholly owned subsidiary of SpaceX, valuing the combined company at $1.25 trillion, according to Bloomberg's reporting at the time.⁵ The deal folded in Grok (xAI's family of language models), the social network X (which xAI had acquired in March 2025), and the Colossus supercomputer complex in Memphis, Tennessee.

Musk's stated rationale was orbital computing: AI demand for electricity, he argued, "simply cannot be met with terrestrial solutions" without imposing hardship on communities and the environment.⁵ The merger also solved a more earthbound problem — Bloomberg reported xAI was burning around $1 billion per month, while SpaceX had a profitable launch and Starlink business to absorb it.⁵ Tesla and SpaceX had each already invested $2 billion in xAI in January 2026.⁵

Four months later, the IPO priced the combined company at roughly $1.77 trillion — about 42% above the merger's $1.25 trillion mark.²⁵

Inside the S-1: What SpaceX Actually Earns

SpaceX's S-1, made public on May 20, 2026, gave the first comprehensive look at the company's financials.¹⁰ For 2025, SpaceX reported $18.7 billion in revenue, a $2.6 billion operating loss, and a $4.9 billion net loss, with adjusted EBITDA of $6.6 billion.¹⁰

Starlink is the engine: subscribers grew from 2.3 million in 2023 to 4.4 million in 2024 and 8.9 million in 2025, reaching 10.3 million by the end of March 2026 — though average revenue per user fell from $99 per month in 2023 to $66 by March 2026.¹⁰ The AI segment is the smallest by trailing revenue but, as the next section shows, it holds the largest contracted growth.

Colossus Data Center and the AI Compute Deals

The Colossus data center complex in Memphis is the heart of SpaceX's AI business. Industry infrastructure trackers estimate the Memphis complex houses roughly 555,000 Nvidia GPUs across H100, H200, and GB200 generations, with Musk announcing in January 2026 an expansion toward 2 gigawatts of total capacity.¹¹ That headline capacity deserves skepticism: satellite-imagery analysis reported by Tom's Hardware suggested the Colossus 2 site had only around 350 megawatts of cooling capacity as of that reporting — far short of the claimed figures.¹²

What is not in dispute is who's paying for the compute. The S-1 disclosed two anchor contracts:

Anthropic announced its SpaceX partnership in early May, and the financial terms emerged in the S-1; the company says the capacity will directly serve its paid Claude subscribers, and it has expressed interest in jointly developing gigawatts of compute in space.⁶¹⁴ Google's deal — striking, given Gemini competes directly with Grok — covers roughly 110,000 GPUs housed in SpaceX data centers.⁷ Musk has said SpaceX is actively seeking more AI compute customers.¹⁵

Once both deals are running, these two contracts alone represent nearly $2.2 billion per month in contracted compute revenue — over $26 billion annualized, dwarfing the AI segment's $3.2 billion in 2025 revenue. That contracted backlog, more than the rockets, is what the IPO price is built on. For a sense of how these rental prices compare to the broader market, see our GPU cloud comparison.

Orbital Data Centers: The Million-Satellite Bet

Orbital data centers are SpaceX's proposed network of computing satellites that would run AI workloads in space using near-constant solar power. In a filing submitted to the FCC on January 30, 2026, SpaceX proposed a constellation of up to one million satellites operating between 500 and 2,000 kilometers in low Earth orbit; the FCC's Space Bureau accepted the filing for review on February 4.¹⁶

The design relies on optical intersatellite links to move data between the constellation and Starlink spacecraft, which relay it to the ground. Satellites in sun-synchronous orbits — in sunlight more than 99% of the time — would handle constant workloads, while lower-inclination satellites would absorb demand peaks.¹⁶ SpaceX asked the FCC to waive standard deployment milestones, which normally require half a constellation within six years.¹⁶ The prospectus says IPO proceeds will fund AI compute infrastructure, launch vehicles, and satellite constellations — making the public market the financing vehicle for this bet.

It is worth being clear about the stage this is at: a regulatory filing is not a deployed system, and the technology for large-scale orbital compute remains unproven.

The Catch: Musk's 85.1% Voting Control

SPCX stock comes with one of the most concentrated governance structures of any mega-cap listing. The dual-class structure gives Class A shares (what the public bought) one vote each, while Class B shares carry ten votes. Musk owns 12.3% of Class A shares and 93.6% of Class B shares — a combination giving him 85.1% of total voting power.⁸

SpaceX will claim controlled-company status, exempting it from exchange rules requiring a majority-independent board. Musk will simultaneously hold the CEO, CTO, and board chairman roles, and removing him would require votes he himself controls.⁸ Institutional investors, including the New York City and New York State comptrollers and CalPERS, publicly raised governance concerns ahead of the listing.⁸ Public shareholders are along for the ride — they are not steering.

The AI IPO Wave: Anthropic and OpenAI Are Next

The SpaceX listing is the opening act of an extraordinary quarter for AI public offerings. Anthropic confidentially filed a draft S-1 with the SEC on June 1, 2026, days after closing a $65 billion Series H round on May 28 at a $965 billion post-money valuation.¹⁷¹⁸ OpenAI confirmed its own confidential S-1 submission on June 8, 2026; its most recent funding round, closed in March, valued it at $852 billion.¹⁹

If all three complete their listings, U.S. markets could absorb three of the largest offerings ever within roughly one year — each one, at its core, a bet on AI infrastructure economics. We covered the mechanics of OpenAI's path in our breakdown of the OpenAI IPO confidential filing and its record $122 billion funding round.

The Bottom Line

The SpaceX IPO is being reported as a space story, but the S-1 reads like an AI infrastructure prospectus: a contracted compute backlog from Anthropic and Google worth nearly $2.2 billion per month, the Colossus data center complex, and a million-satellite orbital compute filing at the FCC. Starlink pays the bills today; the valuation is a bet on AI compute — terrestrial first, orbital later. The risks are equally clear: a $4.9 billion net loss in 2025, unproven orbital technology, and a governance structure that gives public shareholders essentially no say. With Anthropic and OpenAI S-1s already in the SEC's queue, today's SPCX debut is the first real test of whether public markets will pay private-market prices for AI infrastructure.
