SpaceX opens its books on the road to a public offering

SpaceX has filed an S-1 registration statement with the U.S. Securities and Exchange Commission, formally launching the process for what could become one of the most closely watched IPOs in years. The filing, submitted after markets closed on May 20, does not yet specify share count or pricing, but it does something the privately held company has largely avoided until now: it provides a broad look at the scale of the business behind launch, broadband, and its newly defined AI segment.

According to the source material, SpaceX is seeking to raise up to $80 billion at a valuation of around $2 trillion, although those figures are attributed to outside reports rather than the filing itself. What the filing does establish directly is that SpaceX has become a very large operating company with multiple revenue streams and sharply different margin profiles across its business lines.

For 2025, the company reported revenue of $18.7 billion and adjusted EBITDA of $6.6 billion. In the first quarter of 2026, it recorded $4.7 billion in revenue and adjusted EBITDA of $1.1 billion. Those figures alone would make the offering consequential, but the segment breakdown is where the filing becomes especially revealing.

Starlink is carrying the business

The connectivity segment, which includes Starlink, generated the majority of SpaceX’s revenue and earnings. The filing says that segment produced $11.4 billion in revenue in 2025 and $3.3 billion in the first quarter of 2026. Adjusted EBITDA for connectivity reached $7.2 billion in 2025 and $2.1 billion in the first quarter of 2026.

Those numbers suggest that Starlink is not simply an adjacent bet supporting launch economics. It is the company’s main financial engine. The filing also says SpaceX had 10.3 million Starlink subscribers at the end of the first quarter of 2026, up from 5.0 million a year earlier. That pace of growth helps explain why public-market investors are likely to focus at least as much on broadband economics as on rockets.

The strategic result is clear in the numbers. Launch may remain the company’s defining brand, but connectivity is the business unit funding scale, supporting margins, and likely shaping investor interest. Public investors looking at SpaceX will be buying into a hybrid company, one part launch provider and one part global communications platform.

Launch remains central, but Starship is expensive

The filing’s space segment includes launch and related activities such as Dragon. It brought in $4.1 billion in revenue in 2025 and $619 million in the first quarter of 2026. Adjusted EBITDA for that segment was positive at $653 million in 2025, but turned adjusted negative at $351 million in the first quarter of 2026.

The document points directly to a major reason for that pressure: Starship. SpaceX says it spent $3 billion on Starship development in 2025 and another $930 million in the first quarter of 2026. Those figures underline the scale of the company’s willingness to spend against a long-term transportation system that is not yet contributing comparable commercial returns.

That does not make the investment irrational. It clarifies the company’s operating model. SpaceX is using mature or maturing businesses to finance a capital-intensive vehicle program that it believes will define its next phase. The filing says Starship is scheduled to perform its 12th suborbital test flight as soon as May 21 and that the company expects it to begin launching satellites in the second half of the year.

If that schedule holds, investors will be weighing a familiar high-growth tradeoff: a profitable scale business in Starlink against a cash-hungry strategic platform in Starship. The market will not just be judging revenue growth. It will be pricing faith in execution.

A new AI segment adds another layer

The filing also states that SpaceX now reports an AI segment created from its acquisition of xAI in February. That segment provided $3.2 billion in revenue in 2025, according to the source text. Even without a fuller operational breakdown in the supplied material, the existence of a separate AI reporting category changes how the company can be presented to investors.

Instead of arriving on the market as a pure-play aerospace company, SpaceX is showing up as a three-part enterprise: space, connectivity, and AI. That makes comparison harder, but it also potentially broadens investor appetite. Some buyers may see a launch and satellite company. Others may see a broadband giant with space infrastructure. Others may focus on the AI angle and the optionality that comes with it.

The complexity cuts both ways. A multi-segment story can support a higher ambition, but it also forces more scrutiny on capital allocation, reporting clarity, and whether each unit’s economics stand on their own.

Why this IPO matters beyond one company

This filing is important not only because of SpaceX’s scale but because it puts hard numbers behind a company that has shaped entire markets while operating with limited public disclosure. Launch pricing, satellite broadband, reusable rockets, and now orbital transport have all been influenced by SpaceX’s posture. With an IPO filing, the discussion shifts from reputation and market impact to formal financial evidence.

The early disclosure points to a company that is already massive, profitable in important areas, and still willing to spend aggressively on programs that may define its future. That combination is likely to appeal to investors, but it also makes the offering unusually exposed to execution risk. Starship timelines matter. Subscriber growth matters. Segment transparency matters.

What the filing makes clear is that SpaceX is no longer just a private aerospace standout that occasionally releases milestones. It is preparing to be judged like a public industrial and technology company, quarter by quarter, with its launch business, broadband network, and AI ambitions all under the same market lens.
