For years, the question of when SpaceX would go public was treated as one of the great unknowns of the technology world. Elon Musk resisted. The company didn’t need the money. The public markets couldn’t handle the valuation. The moment never seemed right.
That moment has now arrived — and it has arrived at a scale that makes every previous technology IPO look like a warm-up act.
SpaceX has filed confidentially with the Securities and Exchange Commission for a public offering targeting a valuation north of $1.75 trillion. If achieved, it would be the largest initial public offering ever recorded in history — not just in technology, not just in America, but anywhere, ever.
The Numbers That Rewrite the Record Books The figures attached to this filing are difficult to contextualise because nothing quite like them has existed before.
The capital raise is targeting between $50 billion and $75 billion — a range that, at its midpoint, more than doubles the previous record held by Saudi Aramco, which raised $29 billion in its 2019 listing on the Riyadh stock exchange. That offering was considered extraordinary at the time. SpaceX is prepared to raise more than twice that amount in a single transaction.
The timeline is equally striking. A confidential SEC filing puts the offering on track for a June listing — meaning SpaceX is positioned to beat both OpenAI and Anthropic to public markets. For an industry that has spent years anticipating which AI company would go public first, the answer has arrived from an unexpected direction: not a pure AI lab, but a rocket company that absorbed one.
The xAI Absorption: The Strategic Move Nobody Saw Coming Before filing, Musk absorbed xAI — his artificial intelligence venture — directly into SpaceX. The move was bold, strategically elegant, and changes the nature of what investors are actually buying.
xAI currently generates under $1 billion in revenue, set against the rocket and launch business’s approximately $20 billion. On pure revenue metrics, xAI is a small fraction of the whole. But that framing misses the point entirely.
What Musk has created with this absorption is a company that can make a pitch no other organisation on earth can currently replicate: rockets, artificial intelligence, robotics, and data infrastructure under a single public listing. SpaceX launches satellites. Starlink provides global internet connectivity. xAI develops large language models. The Optimus robotics programme sits at the frontier of physical AI.
Each of these businesses, separately, would be among the most talked-about technology investments of the decade. Together, under one ticker, they represent something genuinely unprecedented.
“For all the talk of AI mega-IPOs centring on OpenAI and Anthropic, it is xAI via SpaceX that will be the first US AI lab to hit public markets.”
Retail Access — With a Catch Around 30% of shares will be made available to everyday retail investors — a deliberately inclusive allocation that signals Musk’s awareness of the political and reputational value of broad public ownership.
But the structure comes with a significant caveat. A two-tier voting structure ensures that Musk retains full operational control of the company regardless of how many shares change hands in the public markets. Retail investors will own a piece of SpaceX. They will not have a meaningful voice in how it is run.
This is not unusual for technology IPOs — Meta, Alphabet, and Snap all went public with similar structures. But in the context of a company of this scale, with this diversity of strategic interests, the voting structure is worth noting. Investors in the SpaceX IPO are making a bet on Musk’s judgment, vision, and execution — not on their own ability to influence the company’s direction.
The Race to Public Markets The SpaceX filing fundamentally reorders the narrative around AI IPOs that has dominated technology investment discussions for the past two years.
OpenAI and Anthropic have both been the subject of intense speculation about public offerings. Both have raised enormous private capital at valuations that imply eventual public listings. Both have been positioned, in most analyst frameworks, as the likely first movers in bringing large-scale AI to public markets.
SpaceX, by absorbing xAI and filing now, has cut in front of both. The first US AI lab to trade publicly will not be a company built from the ground up around language models. It will be a rocket company — the most valuable private company in American history — that decided to bring AI along for the ride.
What This Means for Investors and Markets A $1.75 trillion valuation listing in June would arrive into markets already navigating significant uncertainty — the Iran war, elevated oil prices, inflationary pressure, and a Federal Reserve caught between competing priorities.
The timing is either courageous or calculated, and with Musk it is almost certainly both.
For investors, the SpaceX IPO represents an opportunity that is genuinely without precedent: exposure to orbital launch capability, global satellite internet, frontier AI research, and physical robotics — all in a single instrument, all under the management of the most prolific technology entrepreneur of the current era.
The risks are proportional to the ambition. The voting structure concentrates control. The xAI revenue base is nascent. The valuation assumes an extraordinary future. And public markets, unlike private ones, will price these risks daily and visibly.
But for those who believe the next decade will be defined by the convergence of space, AI, and robotics — and that Elon Musk is the person most likely to sit at that convergence — the SpaceX IPO may be the defining investment event of the decade.
No other company can make this pitch. No other founder has built these pieces. And no other IPO in history has carried this valuation to the public markets.
