SpaceX is set to go public in 2026. Analysts believe the company is targeting a valuation between $1 trillion and $1.75 trillion, with plans to raise as much as $50 billion in fresh capital.
That would make it the second-largest IPO in history by valuation, trailing only Saudi Aramco’s $1.7 trillion debut. And it could raise more capital than any IPO ever.
But here’s what makes this different from typical IPO stories: Musk just laid out exactly what he plans to do with that money, and it’s ambitious even by his standards.
The Terafab Plan
Speaking at an event in Texas last week, Musk outlined plans for a new semiconductor facility in Austin called “Terafab.” The facility would be jointly operated by Tesla and SpaceX, starting as an advanced technology fab capable of producing and testing chips before potentially scaling up.
Musk framed this as a supply chain necessity. He sees a gap between surging AI compute demand and the pace of industry supply. Without building chips internally, Tesla and SpaceX risk not securing enough capacity for robotics, autonomous driving, and broader AI initiatives.
The facility would produce two categories of chips: edge and inference processors for Tesla vehicles, robotaxis, and Optimus humanoid robots, plus higher-powered chips designed for space applications tied to SpaceX and xAI (Musk’s AI company, now a wholly owned subsidiary).
The ambition is to eventually target advanced 2-nanometer nodes and support massive compute output—100 to 200 gigawatts annually on Earth, with additional capacity tied to space-based systems.
The Execution Challenge
Semiconductor fabs take years to build and cost tens of billions of dollars. Musk acknowledged the effort would start at a smaller scale before expanding, but there’s no defined timeline yet.
Tesla currently relies on Taiwan Semiconductor Manufacturing, Micron Technology, and Samsung (which has a facility near Austin). Musk indicated those partnerships may not fully meet future demand, which is why internal production matters.
But building a competitive fab from scratch is extraordinarily difficult. Even with SpaceX IPO proceeds, this is a long-term bet with significant execution risk.
SpaceX’s Growth Playbook
The IPO money won’t just fund Terafab. SpaceX has multiple capital-intensive projects that could absorb $50 billion quickly.
Starlink scaling is the most obvious use of cash. Each satellite launch costs billions, and Starlink is already a huge money maker for SpaceX. The company generated $8 billion in profit on $15-16 billion in revenue last year—impressive margins for a capital-intensive business early in its growth phase.
Starlink will be crucial for SpaceX’s direct-to-cell ambitions: super-fast, consumer-priced cellphone service anywhere in the world via satellite network. That’s a massive addressable market if they can execute.
Starship development is next. If successful, Starship would be the largest rocket ever sent to space. That extra volume would help SpaceX scale Starlink faster, but it also enables more speculative projects.
Space-based AI data centers are part of Musk’s vision. Data centers burn electricity cooling GPUs. The vacuum of space poses design challenges, but frigid temperatures in low Earth orbit could dramatically lower cooling costs.
Musk outlined plans for AI data center satellites, starting with a 100-kilowatt prototype and scaling to megawatt-level systems. If anyone could pull this off, it’s SpaceX with leading rocket designs and a pile of IPO cash.
Project Moon rounds out the list—establishing a permanent lunar base. This is highly speculative without a clear revenue pathway, but it’s the kind of moonshot (literally) that captures attention.
The Valuation Debate
Wall Street is split on whether SpaceX can justify a $1.5-1.75 trillion valuation. PitchBook’s recent analysis pegged fair value anywhere between $1.1 trillion and $1.7 trillion.
Their conclusion: “The valuation becomes progressively easier to justify over a 5-7 year horizon as Starship commercializes and the direct-to-cell business scales, with returns driven by milestone execution rather than near-term earnings growth.”
Translation: you’re betting on what SpaceX will become, not what it is today.
At $8 billion in profit on $15-16 billion in revenue, SpaceX is already profitable and growing. But a $1.5 trillion valuation implies significant future growth that hasn’t materialized yet. You’re paying for Starship commercialization, Starlink scaling, direct-to-cell rollout, and the optionality of space-based data centers.
Why This IPO Matters
Extended bull markets mean more companies go public, and we’re still in the midst of a multi-year rally despite recent volatility. Companies that IPO during bull markets typically achieve higher valuations while selling smaller stakes.
SpaceX fits that pattern, but the scale is unprecedented. At $1.5 trillion, this would be the second-largest IPO ever. At $50 billion raised, it could be the largest capital raise in IPO history.
The Terafab announcement adds another layer. Musk isn’t just taking SpaceX public to cash out or provide liquidity. He’s funding a vertically integrated strategy across chips, AI, space infrastructure, and telecommunications.
Tesla and SpaceX would control more of their supply chain. xAI would have dedicated compute infrastructure. Starlink would scale faster. And space-based data centers could unlock entirely new markets.
The Risk
Semiconductor fabs are hard. Space-based data centers are unproven. Starship is still in development. Direct-to-cell service faces regulatory and technical hurdles. Project Moon is a decade away at minimum.
Any one of these could fail or take longer than expected. And at a $1.5 trillion valuation, there’s not much room for error. If execution slips or markets turn, the stock could get crushed.
But that’s the bet. You’re not buying SpaceX for what it is today—you’re buying what Musk thinks it can become with $50 billion and no constraints.
Whether that’s visionary or overvalued depends on your view of Musk’s execution track record and the timeline for these projects to deliver returns.
One thing is certain: this will be one of the most closely watched IPOs in market history.
