The largest IPO in stock market history isn’t coming from a social media platform, a pharmaceutical giant, or a cloud software company. It’s coming from a rocket company and what makes it genuinely extraordinary is that it’s pricing itself as all of those things at once.
On June 12, SpaceX officially goes public on the Nasdaq under the ticker SPCX, targeting a baseline valuation of $1.75 trillion. To put that in perspective: Alibaba’s record-breaking 2014 debut raised $21.8 billion at a $168 billion valuation. Saudi Aramco shattered that record in 2019 at $1.7 trillion. SpaceX is aiming to top both while simultaneously raising up to $80 billion in fresh capital, more than triple what Aramco pulled in.
The numbers are historic. But the question serious investors are asking is simpler than you’d expect: is this actually worth it?
Three Companies Inside One Ticker
Wall Street isn’t just pricing a rocket company or a satellite internet provider. Underwriters are pitching three distinct business pillars rolled into a single offering.
The first two are straightforward: Starlink’s satellite internet business (now at 10.3 million subscribers) and the unmatched launch economics of the Falcon 9 and Starship rockets, which operate at a cost structure no competitor can currently replicate. The third pillar is where the valuation gets genuinely speculative.
Following SpaceX’s merger with Elon Musk’s AI venture xAI, the IPO prospectus frames the combined entity not as a telecom or aerospace company, but as an emerging orbital AI infrastructure giant. Investors buying SPCX shares aren’t just betting on satellites and rockets. They’re betting on a future where xAI’s computing infrastructure including its Grok models is deeply integrated with Starlink’s global satellite network to create something closer to a space-based AI backbone for the global economy.
That framing is what’s driving the $1.75 trillion sticker price. And it’s exactly where the skepticism starts.
Why “10.3 Million Subscribers” Doesn’t Explain a Trillion-Dollar Valuation
If you evaluate Starlink purely as an internet service provider, the math breaks down immediately. Consider Comcast: it has roughly 32 million broadband subscribers, three times Starlink’s base and trades at a market cap of around $150 billion. By that logic, a fair valuation for Starlink as a traditional ISP would land somewhere between $45 billion and $50 billion.
Even accounting for Starlink’s estimated $8 to $10 billion in annual revenue, the IPO is pricing the company at over 70 times revenue, a multiple that makes even Nvidia’s most aggressive trading periods look conservative. Morningstar has openly called this out, initiating coverage with a fair value estimate of $780 billion, roughly half the IPO target.
So what’s justifying the gap?
Four Reasons the Bulls Aren’t Blinking
High-value contracts that aren’t in the headline subscriber count
Standard residential Starlink plans run about $90 to $120 a month. But the real margin lives elsewhere. Major cruise lines like Royal Caribbean and global airlines pay tens of thousands of dollars per month per vessel for maritime and aviation connectivity. More significantly, SpaceX’s Starshield division holds classified defense contracts with the US government and allied nations providing secure, unjammable satellite communications that no competitor currently offers at the same scale. Governments pay a substantial premium for that kind of strategic monopoly.
The launch cost advantage nobody else can replicate
Here’s the structural edge that separates SpaceX from every other satellite internet company: they own the rockets. Amazon’s Project Kuiper needs to buy third-party launch capacity. SpaceX launches Starlink satellites essentially at cost. That vertically integrated margin advantage is enormous and it grows wider every time a competitor’s launch bill comes due.
The xAI merger and the orbital data center vision
The most ambitious and most contested part of the pitch is what SpaceX calls “orbital edge computing.” Instead of transmitting raw global data down to terrestrial data centers, processing it, and beaming it back, the long-term vision involves Starlink satellites acting as distributed, floating micro-data centers, reducing latency and solving data transmission bottlenecks that ground-based AI infrastructure struggles with.
SpaceX’s S-1 prospectus claims a Total Addressable Market of $28.5 trillion. Critics immediately seized on a specific detail: $26.5 trillion of that estimate comes from AI, not rockets or internet subscribers. The company is essentially arguing that xAI’s Grok models will be the brain, and Starlink will be the nervous system of everything.
Pure speculative premium on an unbuilt future
The fourth factor is the most honest to name: it’s a bet, not a current valuation. Analysts at Morningstar have calculated that the probability of the orbital AI infrastructure plan being shelved or heavily delayed sits at around 43%, compared to just a 7% chance of it hitting its most bullish growth targets by 2030. The trillion-dollar gap between fundamental value and IPO price is, in large part, the market pricing in a long-odds outcome that Elon Musk has a historically unusual track record of occasionally making real.
The Numbers Underneath the Vision
The combined 2025 financials from SpaceX’s SEC prospectus don’t make the bull case easier:
Combined revenue (2025)
$18.67B
Net loss (2025)
-$4.93B
AI segment operating loss
-$6.35B
The AI segment alone burned through $6.35 billion in operating losses in 2025 meaning the xAI integration, the very thing justifying the trillion-dollar premium, is currently the biggest drain on the company’s finances. SpaceX is asking public markets to pay a historically high price for a company that is deeply unprofitable, largely because of the bet it’s making on a technology that doesn’t yet exist at the scale being promised.
What You’re Actually Buying and What You’re Not
Two structural details buried in the prospectus matter as much as any revenue figure.
The dual-class share problem: Public investors receive Class A shares. Elon Musk and insiders hold Class B shares with significantly higher voting power. The practical outcome: Musk retains absolute voting control over the company regardless of how many shares he sells. Buying SPCX does not give you meaningful say in how the company is run.
The lockup cliff: Early institutional investors and employees are subject to a strict lockup period that prevents them from selling shares after the IPO. When those restrictions expire in late 2026, a wave of insider selling could hit the open market creating severe price volatility for retail investors who bought in on day one at peak enthusiasm.
A Trillion-Dollar Bet on Space-Based AI
If SpaceX’s orbital AI infrastructure vision works if xAI’s Grok models genuinely integrate with Starlink’s satellite network to create something the world’s militaries, enterprises, and AI companies can’t live without then the $1.75 trillion valuation is the entry price for the most consequential infrastructure company of the next two decades.
If it doesn’t, if the space-based AI bet gets shelved, delayed, or simply doesn’t perform at scale investors are buying a $780 billion rocket and internet company at a $1.75 trillion price tag, with a CEO who controls all the votes and insiders sitting on shares they’ll eventually sell.
Both outcomes are genuinely possible. That’s what makes this the most interesting, and most dangerous, IPO in market history.
