SpaceX Files for Largest IPO in History, Targets $1.75 Trillion Valuation

SpaceX’s confidential IPO filing could reshape how everyday investors access the space economy, with a record retail allocation and a valuation that dwarfs every public offering in history.

On April 1, SpaceX submitted a confidential draft registration statement — known as an S-1 — to the Securities and Exchange Commission, officially setting the stage for what analysts are calling the most consequential initial public offering in capital markets history. The combined SpaceX-xAI entity, formed after a $1.25 trillion merger completed in February 2026, is now targeting a public valuation north of $1.75 trillion and a fundraise of up to $75 billion.

To put that in perspective, the current record holder for the largest IPO is Saudi Aramco, which raised $29 billion in its 2019 debut. The largest U.S. IPO remains Alibaba’s $22 billion listing in 2014. SpaceX’s target would be more than three times larger than either.

What a Confidential Filing Means

A confidential S-1 filing — sometimes called a “draft registration statement” — allows a company to begin the SEC review process without making its financial details public. This is a common strategy for high-profile IPOs because it lets the company address SEC feedback and refine its disclosures privately before the market sees the numbers. SpaceX’s public S-1, which will contain detailed revenue figures, profit margins, and risk factors, is expected in late May — at least 15 days before the roadshow begins.

The roadshow, where company executives pitch the offering to institutional investors, is planned for the week of June 8. About 125 financial analysts from the 21 banks managing the deal are scheduled to meet with the company beforehand. The offering is internally codenamed “Project Apex” and is expected to list on the Nasdaq.

A Record Retail Investor Push

Perhaps the most unusual element of this IPO is its emphasis on everyday investors. Elon Musk is considering setting aside as much as 30% of shares for retail investors — a dramatic departure from the standard 5-10% allocation in most IPOs. Chief Financial Officer Bret Johnsen told a virtual meeting of the underwriting banks that “retail is going to be a critical part of this and a bigger part than any IPO in history.”

Johnsen explained the reasoning: “Those are folks that have been incredibly supportive of us and of Elon for a long time, and we want to make sure that we recognize that.” On June 11, SpaceX plans to host 1,500 retail investors at a major investor event. Beyond the United States, everyday investors in the UK, EU, Australia, Canada, Japan, and South Korea will also have the opportunity to participate — another rarity for an IPO of this scale.

The Numbers Behind the Valuation

SpaceX’s valuation rests heavily on Starlink, its satellite internet service, which has crossed 10 million active subscribers as of February 2026 and is adding more than 20,000 new users per day. Industry research firm Quilty Space forecasts Starlink will reach 16.8 million subscribers by year-end, with total SpaceX revenue tracking toward $20 billion in 2026. The firm projects $14 billion in EBITDA and $8.1 billion in free cash flow — numbers that would make SpaceX one of the most profitable private-to-public transitions ever.

The February 2026 merger with xAI, Musk’s artificial intelligence venture, added another dimension. That deal valued SpaceX at $1 trillion and xAI at $250 billion, creating what Musk described as “the most ambitious, vertically-integrated innovation engine on and off Earth.” The combined entity now spans rocket launches, satellite internet, AI infrastructure, and the social media platform X.

Governance Questions and Investor Risks

Not everyone is enthusiastic. SpaceX plans to adopt a dual-class share structure — a setup where public investors receive Class A shares with one vote per share, while insiders like Musk hold Class B shares carrying 10 to 20 votes each. This would guarantee Musk at least 25% voting control, ensuring he can steer major corporate decisions without shareholder approval. Dual-class structures are common in tech (Google, Meta, and Snap all use them), but critics argue they shield executives from accountability.

Valuation is another concern. At $1.75 trillion, SpaceX would trade at roughly 87 times its projected 2026 revenue — a multiple with no public market comparable at this scale. Some analysts have justified the figure by projecting revenue 10 to 15 years into the future, which introduces significant uncertainty. The integration of xAI also carries risk: despite SpaceX’s strong financial performance, xAI’s significant cash burn could alter investor perception of the combined entity.

Musk’s divided attention is a factor investors will weigh carefully. He currently oversees Tesla, SpaceX, xAI, X, Neuralink, and The Boring Company, and he served as a senior adviser in the federal government earlier this year. Whether one person can effectively lead a $1.75 trillion public company while managing this portfolio of ventures is a question the S-1 will likely need to address.

What the IPO Means for the Space Industry

Beyond SpaceX itself, analysts say the listing could transform how Wall Street views the entire space economy. Chad Anderson, CEO of Space Capital, called it “a Netscape moment for the space economy,” referencing the 1995 IPO that helped legitimize the internet as an investment category. “A lot of capital flooded to the area after that. I think the same thing is happening here with SpaceX,” he said.

Public space companies are already benefiting from the announcement. Rocket Lab surged roughly 10%, Planet Labs jumped more than 10%, and AST SpaceMobile climbed even higher. Glen Anderson, CEO of Rainmaker Securities, said the IPO “has the potential to be a true inflection point for the space economy” and could prompt “a broad re-rating” of sector valuations. “For years, investors have treated space as a niche, high-risk frontier — but a public listing at this scale reframes it as critical infrastructure,” he added.

What to Watch

Public S-1 Filing: The confidential filing must become public at least 15 days before the roadshow. Watch for the full S-1 in late May — it will reveal SpaceX’s detailed financials, risk factors, and how the xAI integration is performing for the first time.

Retail Allocation Details: Musk’s proposed 30% retail allocation would be unprecedented. Watch for the final allocation percentage and which brokerage platforms will offer access — this will determine whether everyday investors can actually participate or if demand overwhelms supply.

Space Sector Ripple Effects: If SpaceX prices at or above $1.75 trillion, expect a wave of institutional capital flowing into publicly traded space companies like Rocket Lab, Planet Labs, and AST SpaceMobile. This could also accelerate IPO timelines for other private space ventures.
