The Largest IPO Filing in History

On April 1, 2026, SpaceX filed a confidential S-1 with the Securities and Exchange Commission, setting the stage for what would be the largest initial public offering ever attempted. The company is targeting a valuation of $1.75 trillion and aims to raise roughly $75 billion, dwarfing Saudi Aramco's 2019 record of $29.4 billion, according to Techi. If successful, SpaceX would debut as one of the most valuable public companies on Earth — ahead of Meta Platforms and Berkshire Hathaway.

The filing comes just two months after SpaceX completed the largest merger in corporate history, absorbing Elon Musk's artificial intelligence venture xAI in a deal that valued the combined entity at $1.25 trillion. That transaction, combined with Starlink's accelerating subscriber growth and an ambitious vision for space-based AI computing, has created a company unlike anything the public markets have seen. But the valuation also raises hard questions about whether investors are paying for reality or for a narrative.

The xAI Merger: From Three Companies to One

The path to this IPO runs through a series of rapid consolidations. In March 2025, Musk merged the social platform X (formerly Twitter) with xAI, with Sullivan & Cromwell valuing X at $33 billion and xAI at $80 billion. Then on January 30, 2026, xAI and SpaceX completed their own merger, creating a combined entity valued at $1.25 trillion — $1 trillion for SpaceX and $250 billion for xAI, according to Yahoo Finance.

The strategic logic centers on what Musk has called "orbital data centers" — the idea that integrating Starlink's global satellite mesh with xAI's large language models could move massive compute workloads into space, leveraging near-constant solar energy and natural radiative cooling. In late January 2026, SpaceX filed with the Federal Communications Commission for a constellation of up to one million satellites that would serve as orbital AI compute infrastructure, operating at altitudes between 500 and 2,000 kilometers.

But the merger also bundled significant liabilities. According to Yahoo Finance, xAI generated roughly $250 million in revenue over six months, against $2.5 billion in losses during the same period — an annual burn rate approaching $5 billion. All original xAI co-founders have departed, according to TechFundingNews, and Musk himself has publicly acknowledged that the AI division requires rebuilding. Investors buying SpaceX stock at IPO are buying xAI's losses alongside Starlink's profits.

Starlink: The Revenue Engine

If the IPO's valuation rests on a narrative about orbital AI, its financial foundation is Starlink. The satellite internet service has become one of the fastest-growing telecommunications businesses in history.

On February 17, 2026, SpaceX announced that Starlink had crossed 10 million active subscribers globally, adding the most recent million in just 53 days, according to Broadband Breakfast. CEO Gwynne Shotwell marked the occasion: "Crossed the 10M active customers mark. So happy to connect so many around the world!" The service now operates in more than 155 countries.

The growth trajectory has been striking. Starlink had fewer than half its current subscriber count at the end of 2024, then more than doubled that figure in just over a year. Quilty Space, a satellite industry research firm, forecasts that SpaceX's Starlink will reach 16.8 million subscribers by year-end 2026, with total SpaceX revenue tracking to $20 billion, per Techi.

TechFundingNews reports that SpaceX generated approximately $16 billion in total revenue and roughly $7.5 billion in EBITDA in 2025. These are strong margins for a capital-intensive satellite business, and they give SpaceX something most pre-IPO tech darlings lack: genuine, growing profitability.

But Starlink alone doesn't justify a $1.75 trillion price tag. Even at $20 billion in projected 2026 revenue, the IPO valuation implies a multiple of roughly 87 times sales — a figure that Techi notes is well beyond what any comparable business commands.

Orbital Data Centers: The Trillion-Dollar Bet

The gap between Starlink's fundamentals and the IPO's asking price is filled by the orbital data center vision. This is where SpaceX's story becomes genuinely unprecedented — and genuinely speculative.

SpaceX's FCC filing from January 30, 2026, proposes deploying up to one million small satellites in low Earth orbit, each equipped with AI processors and solar arrays. The satellites would operate in 30-degree and sun-synchronous inclinations to maximize time in sunlight. Musk has shown illustrations of an "AI Sat Mini" concept, with each unit providing 100 kilowatts of power for onboard computation.

The theoretical advantages are real. Terrestrial data centers face escalating challenges: power grid constraints, water scarcity for cooling, permitting battles with local communities, and surging electricity costs driven by AI demand. An orbital approach would sidestep all of these by tapping near-constant solar energy and using the vacuum of space as a natural coolant.

But the engineering challenges are formidable. Analyst firm MoffettNathanson has estimated that achieving Musk's orbital data center vision would require roughly 3,000 Starship launches per year — approximately eight per day. Starship, SpaceX's next-generation mega-rocket, is central to this plan because only it can carry payloads large enough for the V3 satellite constellation. Yet Starship remains in the suborbital test phase with a mixed record of test flights that have included multiple explosive failures.

As one analyst told the Motley Fool, the valuation is "only justifiable if Starlink continues to grow rapidly and if the space-based data centers move from theoretical to practical" — goals that remain years away from validation.

The IPO Mechanics: Project Apex

The offering itself is as ambitious as the company behind it. Internally codenamed "Project Apex," SpaceX has assembled a syndicate of 21 banks — one of the largest underwriting groups in recent IPO history. Morgan Stanley, Bank of America, Citigroup, JPMorgan Chase, and Goldman Sachs are serving as lead bookrunners, with 16 additional banks handling institutional, retail, and international channels.

One unusual feature stands out: SpaceX plans to allocate up to 30% of IPO shares to retail investors, according to Techi — roughly three times the typical allocation for large offerings. The company reportedly plans to host 1,500 retail investors at a dedicated event following the roadshow in June. If the full $75 billion raise proceeds, the retail tranche alone would represent roughly $22.5 billion in shares — more than many entire IPOs.

The public S-1 is expected in late April or May, with the roadshow launching in early June and the Nasdaq listing targeted for later that month. Demand is expected to be overwhelming: multiple reports suggest the offering could be 10 to 20 times oversubscribed.

Musk currently holds approximately 42% voting control and a roughly 54% economic stake. A dual-class share structure is widely expected, which would preserve Musk's control over corporate decisions regardless of public shareholder sentiment.

The Valuation Question: Vision vs. Fundamentals

The core tension of this IPO is the gap between what SpaceX earns today and what it's asking investors to pay for tomorrow.

Yahoo Finance's analysis frames the disconnect starkly: at a $1.5 trillion valuation scenario, the combined entity would trade at roughly 94 times trailing sales and approximately 500 times trailing earnings, which the outlet describes as "a bit extreme." For comparison, the Motley Fool notes that Meta Platforms generates $200 billion in annual revenue at a $1.45 trillion valuation — meaning SpaceX would command a similar market capitalization on roughly a tenth of the revenue.

The valuation trajectory itself tells a story about narrative power. According to TechFundingNews, SpaceX was valued at roughly $800 billion just three months before the filing. The $950 billion jump to $1.75 trillion was driven primarily by the AI narrative attached to the xAI merger and orbital data center plans — not by a proportional increase in revenue or profit.

Counterarguments exist. SpaceX commands more than 60% of the global commercial launch market, a dominance that shows no sign of eroding. Starlink is growing at a pace that few telecommunications businesses have ever matched. The $22 billion backlog of government contracts with NASA, the Department of Defense, and the Space Force provides revenue visibility that pure consumer businesses lack. And if orbital data centers prove viable, the addressable market could be enormous.

But history offers cautionary precedents. Both Saudi Aramco and Meta Platforms — the two largest IPOs before this one — experienced extended post-debut struggles. Investors who bought at the offering price waited years to see sustained returns.

The Musk Variable

No discussion of SpaceX's IPO is complete without addressing Elon Musk's role as both the company's greatest asset and its most significant risk factor.

Musk's engineering ambition built SpaceX from a startup that couldn't reach orbit into the dominant force in commercial spaceflight. His willingness to absorb failures — literal explosions — and iterate has produced the world's only reusable orbital-class rockets. That track record is precisely why investors are willing to pay 87 times revenue.

But Musk now operates across SpaceX, Tesla, xAI, X, Neuralink, and The Boring Company. The Motley Fool's Sean Williams observes that "many of Musk's promises have failed to come to fruition," citing Tesla's Level 5 autonomy claims that have remained "one year away" for over a decade while Full Self-Driving remains at Level 2. When Musk's attention has shifted away from Tesla, its sales growth has stalled.

At SpaceX, the key-person risk cuts both ways. Musk is the visionary who conceived Starlink, drove reusable rocketry, and now champions orbital data centers. He is also the executive whose divided attention could slow execution on any of these ambitious programs. The dual-class share structure means public shareholders will have limited ability to influence the company's direction regardless of how Musk allocates his time.

What This IPO Means Beyond SpaceX

The SpaceX IPO is not just a corporate event — it's a market-defining moment that will shape how investors value frontier technology companies for years to come.

If the offering succeeds at a $1.75 trillion valuation, it establishes a pricing benchmark that other AI-adjacent companies will reference. TechFundingNews reports that the SpaceX IPO could influence pricing for anticipated offerings from OpenAI and Anthropic later in the year. A successful SpaceX debut at triple-digit revenue multiples would give those companies and their investors permission to aim higher.

Conversely, if the market rejects the valuation — or if the stock follows Aramco's and Meta's pattern of post-IPO decline — it could cool the broader enthusiasm for AI-narrative IPOs and reset expectations for the entire cohort.

The offering also tests a structural question: whether a company can successfully go public while still in the early stages of its most ambitious business line. Starlink is proven. Launch services are profitable. But orbital data centers remain a PowerPoint presentation backed by an FCC filing. Investors are being asked to fund the transition from what SpaceX is to what it might become.

Key Takeaways

• Record scale: SpaceX's $75 billion raise at a $1.75 trillion valuation would be more than 2.5 times the size of Saudi Aramco's 2019 record, making it the largest IPO in history.
• Starlink drives the fundamentals: With more than 10 million subscribers, approximately $16 billion in 2025 revenue, and roughly $7.5 billion in EBITDA, Starlink provides the profitability foundation — but alone cannot justify the asking price.
• Orbital data centers fill the valuation gap: The vision for space-based AI computing is compelling but unproven, requiring a Starship program that remains in suborbital testing and a launch cadence far beyond current capabilities.
• Governance favors Musk: A dual-class structure preserving 42% voting control means public shareholders will have limited influence over strategic direction, including how xAI's significant ongoing losses are managed.
• Broader market implications: The IPO's success or failure will set the pricing tone for subsequent AI company offerings, including potential listings from OpenAI and Anthropic.
