SpaceX files amended S-1 for $28.5 trillion TAM IPO

SpaceX filed an amended S-1 Monday ahead of its June 12 Nasdaq debut, revealing $18.7 billion in 2025 revenue alongside a $2.6 billion operating loss and a dual-class structure that cements Elon Musk's control.

"The filing confirms SpaceX is three businesses in one — a profitable Starlink, a money-losing launch business, and an AI segment burning $6.4 billion a year," said Tom Brennan, IPO and M&A analyst at Edgen.

Starlink generated $11.4 billion in revenue and $4.4 billion in operating income last year, while the space segment posted $4.1 billion in revenue with a $657 million operating loss. The AI division — encompassing xAI and X — brought in $3.2 billion but lost $6.4 billion. The company claims a total addressable market of $28.5 trillion, with $26.5 trillion tied to AI and just $2 trillion to space launch and Starlink.

The IPO is the most anticipated listing in market history, but the valuation debate hinges on whether investors will price the company on its profitable connectivity business or on speculative AI and Mars-colony ambitions that the S-1 itself acknowledges rely on "technologies that do not exist."

SpaceX will list on the Nasdaq under the ticker SPCX with a dual-class share structure giving Class B shares — held by Musk and other insiders — 10 votes each versus one vote for Class A shares sold to the public. The company designated itself a "controlled company" under Nasdaq rules, allowing it to skip requirements for a majority-independent board and independent compensation and nominating committees. Musk's shares are subject to a one-year lock-up agreement with lead underwriter Goldman Sachs Group Inc.

The amended filing also revealed that over 1 billion Class B shares would vest subject to market capitalization milestones and the "establishment of a permanent human colony on Mars with at least one million inhabitants," contingent on Musk's continued employment through the certification date. Investor Gary Black of The Future Fund LLC said the filing language around issuing "significant amount of equity in connection with future transactions" could signal a possible merger with Tesla Inc., a view echoed by Wedbush analyst Dan Ives, who predicted a merger in 2027.

SpaceX listed American Airlines Group Inc. as a Starlink customer under an agreement to provide onboard Wi-Fi. The company also disclosed a deal with Anthropic to supply compute capacity backed by approximately 325,000 Nvidia Corp. GPUs.

The $28.5 trillion TAM figure has drawn skepticism given that more than 90 percent of it depends on AI — the segment currently losing the most money. The last time a company went public with a TAM-to-revenue ratio of this magnitude was during the 2021 SPAC boom, and most of those companies trade below their IPO prices. For SpaceX, the path to profitability requires Starlink's growth to offset AI cash burn while the launch business moves toward breakeven — a timeline the S-1 says "may be difficult or impossible to determine."
