SpaceX's IPO and what it reveals about Musk in 2026

SpaceX's S-1 has been circulating among analysts for weeks and concrete figures are now on the table. According to TechCrunch, the registration document includes 36 pages dedicated exclusively to risk factors, a number that in itself says a great deal about the complexity of the business. The target valuation sits at 1.75 trillion dollars, which would make SpaceX the largest IPO in the history of U.S. markets.

The number itself is striking, but what surrounds the number is what deserves attention. The total addressable market cited in the S-1 itself amounts to 28 trillion dollars, an estimate that includes satellite launches, global connectivity via Starlink, and, according to the document, activity related to the eventual colonization of Mars. Elon Musk's compensation package is explicitly tied to that last milestone.

What the S-1 says beyond the headlines

An SEC registration document is not a press release: it is drafted by lawyers, subject to regulatory review, and contains the figures the company is willing to defend publicly. That gives it different weight than any post on X or statement in a podcast.

The points that have circulated most among investors and analysts this week are three:

• Target valuation of 1.75 trillion dollars. It surpasses Saudi Aramco's 2019 IPO (1.7 trillion) and nearly doubles the current market capitalization of many major tech companies. If it materializes, it redefines the reference ranges for exits to market in the private sector.
• TAM of 28 trillion dollars. Total addressable market is the figure companies use to justify aggressive valuations. A TAM of that size requires SpaceX to gain market share in sectors that today either don't exist or are marginal: interplanetary transport, orbital infrastructure, long-range telecommunications. Skeptical analysts have already noted that mixing real and measurable Starlink revenues with Martian projections in the same TAM is, at minimum, an act of faith.
• Compensation tied to Mars. The S-1 links part of Musk's compensation package to the milestone of establishing a colony on Mars. It's the first time a regulatory document of this caliber has included such a condition. From a corporate governance perspective, it's unusual; from a narrative perspective, it's consistent with SpaceX's public story for years.

Why it matters beyond the space sector

SpaceX is not a conventional technology company, but its IPO will affect the broader ecosystem of hardware, deeptech, defense, and satellite telecommunications startups. A successful IPO at that valuation would open the door for other companies in the sector that have been waiting for favorable market conditions for years. A failed IPO, or a sharp post-listing correction, would have the opposite effect.

There's also a regulatory dimension. SpaceX operates with top-tier government contracts (NASA, Department of Defense) and will now trade on public markets. Exposure to the scrutiny of shareholders, analysts, and financial media changes the dynamics of how the company is managed, regardless of who holds voting control.

For European institutional investors and sovereign wealth funds that have historically been excluded from SpaceX's private rounds, the IPO represents the first real point of access. That's not a minor detail at a time when competition between private actors and government agencies in space is accelerating.

Who should follow this closely

Those working in satellite communications infrastructure, defense technology, or venture capital funds with deeptech exposure have direct reasons to follow the registration process. Those operating in the AI ecosystem, including those who read ClaudeWave regularly, have an indirect interest: Starlink is the connectivity infrastructure in areas without fixed coverage that makes it possible to deploy AI agents and services in remote or emergency contexts.

For now, the S-1 is a document, not a confirmed launch date. The regulatory process could stretch on for months. But the numbers are already on the table and they're not going anywhere.

Editorial view: SpaceX's S-1 is a document of maximum ambition written with maximum legal precision. The valuation could make sense if Starlink keeps growing and government contracts hold steady; the Martian part of the TAM is another matter. It's worth reading the 36 pages of risks before the executive summary.
