SpaceX IPO Prospectus Reveals Starlink's Role: Profit Cornerstone but Not the Growth Engine
N.R. Finch
SpaceX is targeting a roughly $2 trillion valuation for its IPO, but the prospectus makes clear that AI — not Starlink — anchors the growth narrative; Starlink accounts for under 6% of the company's stated $28.5 trillion addressable market.
A $2 trillion valuation — what story supports it?
SpaceX aims to raise over $75 billion through the IPO, citing a total addressable market of $28.5 trillion.
AI alone accounts for $26.5 trillion of that figure. Starlink broadband plus mobile totals roughly $1.6 trillion.
This means → in the prospectus narrative, AI is the ceiling; Starlink is positioned as "the part that already makes money."
How much is Starlink actually earning?
In 2025, Starlink's "connectivity" segment generated $11.4 billion in revenue — the highest of SpaceX's three divisions and the only one turning a profit.
Launch services brought in $4.1 billion; the AI division, $3.2 billion. Neither is profitable.
In plain terms = Starlink is the only SpaceX business that pays for itself right now. Rockets and AI are both still burning cash.
The $26.5 trillion AI market — what's inside?
The prospectus breaks AI's addressable market into four segments: infrastructure at $2.4 trillion, consumer subscriptions at $760 billion, digital advertising at $600 billion, and enterprise applications at $22.7 trillion.
Enterprise applications alone make up over 85% of the AI total — the single largest line item in the entire valuation story.
This means → SpaceX is betting its future on serving enterprise-grade AI demand through space infrastructure. Whether that logic holds is the central question behind the valuation.
Where will the IPO capital go first?
Analyst Ryan Vanzo believes investors may assume AI will get the lion's share of resources, but he expects Starlink won't be starved of capital.
His reasoning: Starlink is already profitable; continued investment reduces the need for future equity dilution. Its broadband expansion and mobile growth opportunities are clearer and more near-term.
The prospectus itself states: "Starlink Mobile will be a significant new source of growth for the connectivity business."
Is mobile the next chapter for Starlink?
Starlink's mobile business is partnering with terrestrial carriers to eliminate coverage dead zones, with the potential to evolve into a standalone cellular service.
Broadband is already scaling; mobile is in the early stages of partnership deployment.
This reflects a two-step growth path: broadband secures the base, mobile opens new territory.
I would be surprised if Starlink is not one of the company's top priorities.

How intense is the AI arms-race backdrop?
Alphabet recently announced an $80 billion stock sale specifically to fund AI infrastructure expansion.
Vanzo expects SpaceX will likewise direct significant new capital toward AI.
In plain terms = the entire industry is racing to pour money into AI infrastructure, and SpaceX can't sit that race out — but Starlink, as "the leg that already makes money," is precisely what gives it a safety cushion in a cash-burning competition.
