Elon Musk’s 250-plus-page SpaceX IPO filing lays out staggering valuations, losses, spending and control—along with compensation tied to market caps in the trillions. If the offering priced next month proceeds as planned, the deal would rank as the largest eve
On a page-count so high it feels like a novel. Elon Musk’s SpaceX IPO filing spells out a world where the smallest details still point back to the biggest numbers: trillions in valuation. billions in losses and spending. and a compensation plan that only completes at market-cap heights most companies never reach.
The document. running more than 250 pages. is the prospectus for the rocket maker’s stock debut and lays out what SpaceX says it needs to keep building toward Musk’s long-term aim of making humans an interplanetary species. Money raised in the initial public offering is reportedly about $75 billion and is expected to help finance those plans.
If the IPO “goes off without a hitch,” it would be the largest ever. It could also make Musk—the major SpaceX owner who is already described as the world’s richest man—the first trillionaire.
The filing, in part, reads like a pitch for a future that starts with escape velocity and ends with permanence. Musk describes using his rockets to save the human race from extinction by making it an interplanetary species. First, he will send men to the moon, then, maybe, Mars. On Mars, he hopes to build a permanent one-million-person colony.
The numbers tell the story of how ambitious that timetable is—and how tightly Musk’s incentives are tied to financial performance.
SpaceX’s expected valuation after its public offering is in the range of $1.75 trillion to $2 trillion. For scale, Nvidia is cited as the world’s most valuable public company at around $5.4 trillion. Nvidia went public in January 1999 and first closed with a market value above $2 trillion in March 2024.
But even as SpaceX is moving toward a public market, the filing also points to strain in the present. SpaceX’s loss for the full year 2025 is listed at $4.9 billion. The filing notes that Tesla, Musk’s electric-vehicle company, went public in 2010 but didn’t earn an annual profit until 2020.
Musk’s personal stakes are laid out with numbers that make his involvement feel less like a hobby and more like a high-wire bet. His net worth is listed as $839 billion as of May 20, according to Forbes. Musk is described as a major stockholder in SpaceX. and he also stands to reap hundreds of billions of dollars from a compensation package awarded to him at Tesla. assuming he hits certain ambitious financial and business metrics.
Control matters, too—especially once shares enter the public market. The filing says Musk controls 85.1% of SpaceX voting power by virtue of owning more than 90% of the company’s Class B shares. which give the holder 10 votes for every share held. It also says he owns a 12% stake in the Class A shares, which carry one vote.
There’s a hard reality built into the compensation math: it reaches for Mars long before Mars can reliably hold that kind of population. The filing says at least 1 million inhabitants would need to live in a colony on Mars for Musk to receive a part of his SpaceX compensation package. It also points out there are no current capabilities of transporting one human to Mars, let alone 1 million.
The top line of that same compensation structure is even starker. The filing lists $7.5 trillion as the top market capitalization SpaceX would have to reach for Musk to receive his full compensation. It also compares that figure to a separate political benchmark: Trump’s proposed defense budget for fiscal year 2027 is cited at $1.5 trillion.
SpaceX’s reach doesn’t live only in rockets and speeches. The filing gives a picture of the scale of its satellite business as well. It lists 9,600 Starlink satellites in orbit. It provides comparisons meant to show how vast that number is relative to other transportation and infrastructure footprints: UPS says it has 135. 000 delivery vehicles. including motorcycles. in its fleet. while Delta Air Lines has a fleet of more than 1. 200 when regional airline partners are included.
Even the timing of how and when insiders can sell is quantified. Musk is required to hold on to his SpaceX stock for 366 days before he’s able to sell or transfer it. according to the filing. The document describes this as a lock-up period designed to prevent insiders from dumping their shares or cashing out immediately. It notes other top SpaceX investors have to wait 180 days.
The document also includes what SpaceX spent to keep its business running—across rockets, satellites and artificial intelligence technology. It says SpaceX spent $20.7 billion in 2025 for all its units. Of that total, the bulk—just under $11.4 billion—came from its connectivity unit that includes its Starlink satellites.
There’s an example of the cross-company ecosystem, too. The filing says SpaceX spent $131 million in 2025 on Cybertrucks from Musk’s other public company, Tesla. It pairs that figure with Tesla’s pricing: the base model of a Cybertruck costs $69. 990. meaning the $131 million would purchase 1. 871 vehicles.
The prospectus’ numbers. placed side by side. create a portrait of a company that is already spending at a planetary scale—while asking public investors to help finance the leap to the next stage. The filing also makes one thing clear: for Musk, the payout is not just about going public. It’s about hitting milestones that reach far beyond launch pads—toward moon missions. a potential Mars colony. and market caps in the trillions.
