The S-1 Is Out. Here's What's Actually In It.

SpaceX filed its full public prospectus with the SEC on Wednesday, May 21. The roadshow is still set to kick off June 8, targeting a Nasdaq listing under ticker SPCX. Goldman Sachs leads the underwriting, followed by Morgan Stanley, Bank of America, Citigroup, and JPMorgan Chase, according to CNBC.

Our previous coverage flagged the $75 billion raise target and the $28.5 trillion addressable market claim. The actual S-1 is now public. The numbers are real. So are the red flags.

Musk's Control Is Not 'Strong.' It's Absolute.

Musk will hold 93.6% of the Class B super-voting shares post-IPO. Those shares carry 10 votes each. Public investors get Class A shares — 1 vote each. Musk retains more than 50% of total voting power even after the largest IPO in history.

He will simultaneously serve as CEO, CTO, and chairman of the board. He can appoint directors as he sees fit. He essentially cannot be fired. SpaceX states in the filing: "This will limit or preclude your ability to influence corporate matters and the election of our directors."

Ann Lipton, professor of law at the University of Colorado, noted that Musk is effectively eliminating the three main levers shareholders normally use to pressure executives — voting, legal challenges, and board oversight. SpaceX incorporated in Texas, where Musk helped shape a more permissive regulatory environment, and the filing limits how shareholders can file legal challenges.

Compare that to Tesla, where Musk holds only around 20% voting control and has faced years of shareholder pressure. At SpaceX, that fight doesn't exist. Public investors are passengers.

The Mars Bonus Is Real — and Absurd

Buried in the filing: Musk is eligible for up to 1 billion additional Class B shares contingent on 1 million people living on Mars in a SpaceX colony. He can already vote those shares now.

At a $1.7 trillion post-IPO valuation, 1 billion shares represents a staggering figure. The condition is science fiction. The mechanism is not.

The Business: Starlink Carries Everything

Starlink is the only part of SpaceX that makes money.

SpaceX's connectivity unit — primarily Starlink — generated $11.39 billion in revenue in 2025, accounting for 61% of total sales, according to CNBC. That figure jumped to 69% in Q1 2026. Operating income from Starlink: $4.42 billion.

Everything else lost money. The rocket launch division — NASA contracts, Defense Department work, the Falcon 9 program — posted an operating loss of $657 million. The AI division, which includes xAI, lost $6.35 billion.

SpaceX has spent more than $15 billion on the Starship program to date. Starship V3 launched its 12th test flight the same day the S-1 dropped — from a new pad at Starbase, Texas. SpaceX called Starship "key" to accelerating the Starlink constellation build-out. It's also central to every Mars and orbital ambitions Musk has publicly made.

Starlink's user base more than doubled to 10.3 million subscribers in Q1 2026 from a year earlier. SpaceX also filed with the FCC to eventually launch up to 1 million satellites into low Earth orbit.

The Insiders Who Win Big

TechCrunch and Business Insider identified the top shareholders who stand to cash out at historic levels.

Elon Musk holds just over 6.42 billion shares total — a combination of Class A and nearly 5.6 billion Class B super-voting shares.

Antonio Gracias, founder of Valor Equity Partners and a SpaceX board member since 2010, owns more than 503 million shares — roughly 7.3% of Class A stock before the IPO. At a conservative $1.5 trillion valuation, Business Insider calculates that stake is worth approximately $91.6 billion. Gracias is a longtime Musk confidant who backed SpaceX, Tesla, Neuralink, and The Boring Company, and participated in the failed $97 billion hostile takeover bid for OpenAI earlier this year.

Luke Nosek, co-founder of Gigafund and a PayPal Mafia member, holds nearly 33 million shares. He led Founders Fund's original SpaceX investment.

Gwynne Shotwell, SpaceX's COO, holds nearly 12 million shares.

Subsidiaries tied to xAI entered into nearly $20 billion in equipment lease agreements in the S-1. Musk's companies are doing business with each other — with public SpaceX shareholders eventually on the hook.

The AI Valuation Mania Is Getting Dangerous

Prediction market traders on Polymarket put a 56% chance that SpaceX closes its first trading day above $2.2 trillion. SpaceX generated $18.67 billion in total revenue in 2025. Berkshire Hathaway generated over $350 billion and trades at $1.03 trillion.

Kalshi traders now put 92% odds that OpenAI files for an IPO in 2026. Anthropic: 69% odds.

The market is pricing these companies on the assumption that AI transforms everything. SpaceX is a satellite internet company with a money-losing rocket program and a money-losing AI division. That's the business. The rest is projection.

What This Means for Regular People

If you buy SPCX at IPO, you're betting on Starlink's continued dominance, Starship eventually working at scale, and Musk not doing something unpredictable with his absolute voting control. You have NO meaningful say in how the company is run.

Plenty of investors bought Google and Meta under similar dual-class structures and made money. Those companies had diversified revenue. SpaceX's entire profit engine is one product: satellite internet.

Buy in with your eyes open.
