SpaceX’s S-1 shows Mars pay, compute deals

SpaceX’s S-1 – SpaceX filed the S-1 ahead of its IPO, but what stands out isn’t the valuation. The filing lays out an unusual compensation trigger tied to a “permanent human colony” on Mars, details about Musk’s voting control, and a massive compute arrangement with Anthropi

On Wednesday. SpaceX took the first step toward Wall Street by filing the S-1 paperwork required for its hotly anticipated IPO. The document didn’t answer the question investors are still waiting to see in plain numbers—SpaceX’s estimated stock value and the anticipated public share price remain undisclosed.

What it did provide was a close-up look at how the company—and Elon Musk—plan to turn rockets and artificial intelligence into something investors can measure, down to share counts, milestones, voting power, and long-term compute contracts.

A compensation package built around a “human colony”

The most striking thread in the filing is the way SpaceX ties Musk’s potential payday to a future that reads more like science fiction than standard corporate performance goals.

The filing shows that, among market-cap milestones, SpaceX would need to establish a “permanent human colony on Mars with at least one million inhabitants” for Musk to access a compensation package. Musk would also still have to be employed by SpaceX at the time the milestone is achieved.

Even in a world where IPOs come with complex executive terms, this is unusual: the shares tied to that trigger would be split into 15 tranches.

From there, the numbers implied by the filing get enormous fast.

Musk’s package could reach $737 billion if fully vested

Based on the implied share count in the filing, Musk’s two performance awards could be worth roughly $737 billion if fully vested.

That total includes about $583 billion from a one-billion share award that would vest if SpaceX reaches a $7.5 trillion market cap and establishes a permanent Mars colony.

The filing also points to a second award: about $154 billion from a separate award of about 302 million shares tied to orbital data centers. Those data centers would need to deliver 100 terawatts of compute a year, paired with an additional SpaceX market-cap milestone of about $6.6 trillion.

Anthropic’s compute bill is already running through 2029

SpaceX’s AI strategy is not just a narrative in the S-1—it comes with a contract figure large enough to matter to any forecast.

The filing states that Anthropic is paying SpaceX $1.25 billion a month through May 2029 for access to the rocket company’s compute capacity. In total, the filing pegs that arrangement at about $15 billion in revenue coming from Anthropic.

The compute capacity is connected to SpaceX’s Colossus and Colossus II—massive supercomputers and data centers designed for training AI.

The agreement for cloud and compute services is scheduled to begin in May 2026.

Spending numbers show where the company’s money is going

The S-1 also breaks out capital expenditures by segment—an additional signal of how aggressively SpaceX is backing different parts of its business.

For the three months ended March 31, 2026, capital expenditures for Space segment was $1,052 million, for Connectivity segment was $1,332 million, and for AI segment was $7,723 million. In other words, AI spending dwarfed the other categories during that period.

The contrast is sharper when looking at 2025: the Space segment spending was $3,832 million, while the AI segment spending was $12,727 million.

For a company preparing for public scrutiny, those figures are hard to ignore. They also frame the question many investors will have as they wait for the missing valuation details: if AI is already consuming capital at that scale. how much of that spending converts into returns that can be understood in public market terms?.

Musk’s voting power remains overwhelmingly concentrated

The filing also spells out who truly controls the company’s decisions as it moves toward an IPO.

Voting rights mean each share owned gives the shareholder one vote on eligible matters. The S-1 reveals that Musk—serving as the company’s chief executive. Chief Technical Officer. and Chairman of the board—holds 85.1% of the combined voting power on company matters. based on his 5. 569. 053. 075 shares.

That level of control sits at the center of how SpaceX’s future will be shaped, long before any public share price is priced in.

Groking the company’s direction and the bargain it’s striking

Taken together, the S-1 makes a single storyline hard to miss: SpaceX is preparing to raise visibility in public markets, but the filing’s most concrete disclosures revolve around private-style incentives, long-term compute cash flows, and spending that tilts heavily toward AI.

It’s not the valuation investors are chasing yet. It’s the blueprint for how rewards, resources, and control are arranged—down to milestones that require building a permanent human colony on Mars and data centers delivering 100 terawatts of compute a year.

And as Wall Street waits for the stock details the S-1 didn’t provide, the document leaves investors with a clear sense of what SpaceX wants to bet on—and who will steer the ship as it heads into the public eye.
