The SpaceX IPO has been the most anticipated stock market event in years — and on May 20, the S-1 finally dropped.
For the first time, the public got a real look at the books behind Elon Musk’s rocket company: the revenue, the losses, the AI bets, and a governance structure that keeps Musk firmly in control regardless of how many shares anyone else buys.
Here’s a plain-language breakdown of what the filing actually says — and what it means.
The SpaceX IPO Filing at a Glance
SpaceX submitted its S-1 registration statement to the SEC on May 20, 2026, setting the stage for a Nasdaq debut under the ticker SPCX. The company is targeting a listing as early as June 12, with an investor roadshow beginning around June 8.
The offering could raise between $50 billion and $75 billion, which would make it the largest IPO in history — surpassing Saudi Aramco’s $29.4 billion offering in 2019. At its target valuation of $1.75 trillion, SpaceX would enter the public markets as one of the most valuable companies on the planet.
Starlink Is Carrying the Entire Business
The most important number in the S-1 is this: Starlink, SpaceX’s satellite internet division, generated roughly $11 billion in revenue in 2025 — and in Q1 2026, the Connectivity segment (which is essentially Starlink) accounted for 69% of total company revenue, pulling in $3.26 billion out of $4.69 billion for the quarter.
It’s also the only profitable segment. Q1 2026 operating income from Connectivity was $1.19 billion. Meanwhile, the Space segment posted a $662 million operating loss, and the AI segment — home to Grok — lost $2.5 billion in the same quarter.
The only segment making money
Q1 2026: $3.26B revenue, $1.19B operating profit. Subscriber count grew from 2.3M in 2023 to 8.9M in 2025. Analysts project 2026 Starlink revenue could reach $15–24 billion.
Still burning cash
Q1 2026 operating loss: $662M. SpaceX spent $3B on Starship R&D in 2025 alone and expects Starship to begin orbital payload deliveries in H2 2026. Big bet, still years from payoff.
The biggest drag on profits
Q1 2026 operating loss: $2.5B. SpaceX directed roughly $20B — 60% of capex — toward AI in 2025. The AI division grew only 22% despite that investment, below competitor rates.
Profitable ISP subsidizing ambitious bets
The simplest way to read this S-1: Starlink is a profitable, fast-growing satellite internet business. Everything else — rockets, AI, orbital data centers — is funded by Starlink margins and investor capital.
The Governance Structure: Musk Keeps Control
This is the part of the filing that matters most to anyone actually thinking about buying shares.
SpaceX uses a dual-class share structure. Class B shares carry 10 votes each, compared to 1 vote for Class A shares. Musk holds 93.6% of Class B shares and 12.3% of Class A shares — which translates to 85.1% of combined voting power.
That means public shareholders, regardless of how many shares they accumulate, cannot outvote Musk on any company decision. SpaceX also qualifies as a “controlled company” under Nasdaq rules and opts out of independent board requirements. Musk will serve simultaneously as CEO, CTO, and Chairman after the IPO.
Buying SPCX shares gives you economic exposure to SpaceX’s revenue and growth — but essentially zero governance influence. If you disagree with a strategic decision Musk makes (pouring more billions into xAI, signing the Anthropic compute deal, redirecting cash to Mars missions), you can sell your shares. You cannot change the outcome. This is the deal on offer.
The Anthropic Deal and AI Ambitions
One of the more surprising disclosures in the S-1: SpaceX signed a Cloud Services Agreement with Anthropic in May 2026 for access to the COLOSSUS and COLOSSUS II compute infrastructure — at $1.25 billion per month through May 2029. That’s roughly $15 billion per year, and up to $45 billion over the full contract term.
The filing also reveals a $60 billion option to acquire Cursor, the AI coding tool, which has become one of the most widely used developer products in the industry.
$1.25B/month compute contract
SpaceX is paying Anthropic $1.25 billion per month for access to its COLOSSUS supercomputing clusters. The deal runs through May 2029 — a total commitment of up to $45 billion. This is infrastructure for Grok and future AI products.
$60B option to acquire
SpaceX holds an option to acquire Cursor, the AI-powered code editor that has rapidly become a developer favorite. At $60B, it would be one of the largest software acquisitions in history if exercised.
117M monthly active users
Grok, xAI’s chatbot, counts 117 million monthly active users as of March 31, 2026, out of roughly 550 million total MAUs across integrated platforms. Still well behind ChatGPT’s scale, but growing.
The long-term AI bet
SpaceX wants to deploy AI data centers in orbit, using Starship as the delivery vehicle. The pitch: lower operating costs, global coverage, no terrestrial zoning battles. Still speculative, but it’s in the S-1.
What Investors Should Actually Think About
The honest version of the SpaceX IPO pitch looks like this: you are buying a world-class satellite internet company trading at a very high multiple, and the premium above that is a bet on Starship, orbital data centers, and Grok — all inside a company where Musk holds ten votes to your one.
Starlink is just getting started
Subscribers grew from 2.3M in 2023 to 8.9M in 2025. Analysts project revenues could hit $24B in 2026. If Starship reduces launch costs dramatically, margins expand further. The TAM SpaceX claims: $28.5 trillion.
AI is burning the profits
In 2025, SpaceX swung from a $791M profit to a $4.9B loss. The AI segment lost $2.5B in just Q1 2026. If Grok can’t close the gap with ChatGPT, those losses continue indefinitely — funded by Starlink subscribers.
Musk decides everything
85.1% voting power. CEO, CTO, and Chairman simultaneously. Controlled company exemptions. If Musk decides to deploy capital to Mars missions or double the Anthropic contract, public shareholders have no recourse.
Index inclusion could drive buying
Nasdaq recently changed rules to allow SpaceX to join the Nasdaq 100 within 15 days of listing. That would trigger billions in automatic buying from index funds that have to match the index composition.
⚠️ One detail worth noting: SpaceX is offering equal IPO pricing to retail investors through Charles Schwab, Fidelity, Robinhood, SoFi, and E*Trade — at the same price as institutional buyers. The filing explicitly states retail purchases “will be at the same IPO price, and at the same time, as any other purchases in this offering.” That’s unusual and worth acknowledging.

Starlink is the real business. $11B in 2025 revenue, 69% of Q1 2026 sales, and the only profitable segment. Everything else runs at a loss.
AI spending flipped the company to a loss. $20B in AI capex in 2025 turned a $791M profit into a $4.9B loss. The Anthropic deal alone costs $1.25B per month.
Musk controls 85.1% of voting power. Dual-class shares, controlled company exemptions, and all three top roles. Public shareholders get economic exposure, not governance influence.
Target listing: June 12 on Nasdaq as SPCX. Roadshow starts June 8. If it happens, it would be the largest IPO in history — dwarfing Saudi Aramco’s 2019 record.
