The SpaceX IPO — A Log of what I know

The Numbers, First

On June 12, 2026, SpaceX lists on Nasdaq under the ticker SPCX. The price is $135 per share, a fixed number with no auction, no price range, no negotiation still 4x oversubscribed. This alone is unusual. Goldman Sachs, leading a 21-bank syndicate, is selling 555.5 million shares to raise $75 billion. With the underwriter greenshoe option (an option to sell an additional 83.3 million shares if demand exceeds supply) exercised, that becomes $86.7 billion. At $135 a share, SpaceX is valued at $1.75 trillion, making it the seventh-largest company in the United States on day one, right above Tesla's current market cap of around $1.6 trillion.

Elon Musk will own 42% of the equity and retain more than 82% of the voting control. He is locked up for 366 days before he can sell a single share. His stake on paper: roughly $866 billion.

But here is the part that makes you pause. SpaceX is only selling about 4.2% of the company. The other 95.8% is not going anywhere on listing day. As NC State put it, SpaceX is "selling roughly 4.2% of the company to establish a price for the other 95.8%". That is standard IPO structure, but at this scale it means a $1.75 trillion enterprise is being priced on an exceptionally thin float. Thin floats move fast, in both directions.

The Index Funds Are Already Coming

Here is something that rarely gets mentioned in the same breath as the IPO itself. Within 15 trading days of listing, SpaceX is expected to be included in the Nasdaq 100 and FTSE Russell indexes. Nasdaq literally changed its rules in 2026 to allow "fast entry" for mega-cap IPOs and SpaceX was the obvious catalyst for that change.

What that means in practice: every index fund and ETF that tracks those benchmarks will be forced to buy SpaceX shares automatically, whether or not a fund manager personally believes in the valuation. BNP Paribas estimates that Nasdaq 100 inclusion alone will generate around $8 billion in passive buying in the first month. Roughly 30% of SpaceX's entire free float could be absorbed by passive funds within 15 trading days, according to index forecasting firms.

This creates a mechanical buying wave immediately after listing, which inflates the stock price, which increases SpaceX's weight in the index, which forces funds to buy even more to stay properly allocated. That cycle runs upward until insiders start selling.

Simpler:

When SpaceX gets added to an index, many big funds are forced to buy the stock automatically, which pushes the price up. As the price rises, the stock becomes a bigger part of the index, so funds buy even more, until early investors/company insiders start selling and slow the rise.

What SpaceX Actually Makes

SpaceX filed its first-ever public financials in May 2026. The numbers are real, and they are worth reading carefully.

Full year 2025:

The business has three segments. Starlink, the satellite internet service, generated $11.4 billion in revenue in 2025 (61% of the company) and produced $4.4 billion in operating profit (money the segment made after its own costs, before company-wide expenses). It is the only segment that makes money. Subscribers grew from 4.6 million at end-2024 to 8.9 million at end-2025, and to 10.3 million by Q1 2026. That is a real, growing, subscription business.

The Space segment, meaning rocket launches, payload delivery, NASA crew missions, generated $4.1 billion in revenue but operated at a $657 million operating loss (costs exceeded what it brought in). SpaceX spent close to $3 billion in that segment on Starship R&D alone.

The AI segment, which houses xAI, the Grok chatbot, and X (formerly Twitter), generated $3.2 billion in revenue but posted a $6.4 billion operating loss.

Before SpaceX absorbed xAI in February 2026, the company was actually profitable. It had reported a $791 million net profit in 2025. The xAI merger flipped that entirely.

The valuation of $1.75 trillion against $18.67 billion in annual revenue is a price-to-sales ratio of roughly 94x. Think of it this way: you are paying $94 for every $1 the company currently earns. Goldman Sachs is pitching this with a single number: that SpaceX's AI division revenue will grow from $3.2 billion today to $322 billion by 2030, a 100x increase in five years.

The Comparison That Should Give You Pause

When Google went public in August 2004, it priced at $85 per share for a valuation of $23 billion. Its trailing twelve-month revenue was $3.2 billion and it was profitable. Its price-to-sales multiple at IPO was around 7x. Investors called that expensive. Those investors were wrong, because Google was already dominant in search and compounding at 100% revenue growth per year.

Amazon IPO'd in May 1997 at $18 per share for a market cap of roughly $438 million. Revenue was around $16 million. It had no profits. Its entire bull case rested on the idea that physical retail could be replaced by e-commerce, an idea that was genuinely radical in 1997, and one that took fifteen years to fully arrive.

SpaceX comes to market at a 94x price-to-sales on revenue that includes a deeply loss-making AI unit it acquired four months ago. The bull case requires believing that an AI division losing $2.5 billion per quarter will generate more revenue in 2030 than Nvidia's entire fiscal 2024 revenue of $61 billion.

Goldman Sachs, it is worth noting, is also the lead underwriter on this deal, which means it gets paid when the IPO succeeds. The projection and the incentive structure are not independent.

Why Are People Still Buying This

Starlink has 10 million paying subscribers, zero real orbital competitors, and posted $4.4 billion in operating profit last year. Falcon 9 controls over 60% of the global commercial launch market and is the most reliable orbital rocket ever built. Starship, if it reaches design goals, makes every competitor's cost structure obsolete overnight. These are not projections. These are facts on the ground today. The people writing the largest checks into this IPO are not naive, they are betting that Starlink alone, priced as a standalone subscription business, is worth more than $1 trillion, and the rockets and AI are essentially free upside. That is a reasonable argument.

The Musk Shell Game — And Why It Should Affect Your View of the IPO

To understand why xAI ended up inside SpaceX four months before this IPO, you have to follow the sequence of events. And this is where the story gets a little Wolf of Wall Street.

Musk bought Twitter for $44 billion in October 2022. The platform shed advertisers rapidly. Revenue dropped. The brand became politically polarizing, which accelerated that advertiser retreat. By early 2025, X was a money-losing platform carrying roughly $12 billion in debt.

Here is the part worth paying attention to. When xAI acquired X in March 2025 in an all-stock deal, it valued Twitter at $33 billion, roughly $11 billion less than Musk originally paid for it. That lower valuation was not an admission of failure. In a deal between two Musk-controlled private companies, both represented by the same bank (Morgan Stanley), the valuation is whatever Musk decides it is, as long as investors do not revolt. Critics noted at the time that xAI's own valuation jumped from roughly $50 billion to $80 billion in the transaction, with no new money involved. The math was flexible in a way that only works when one person controls both sides of the negotiation. (Musk said my chocolates are worth 10$ and sold it to Musk)

Then in February 2026, SpaceX acquired xAI entirely in an all-stock deal, creating the combined $1.25 trillion entity that is now going public. This brought X (Twitter), Grok, and all of xAI's losses onto SpaceX's balance sheet.

So, what you are investing in is not a rocket and satellite company, it is a rocket-plus-AI-plus-social-media company.

Meanwhile in another story, Tesla, the public company whose shareholders had no meaningful say in any of this, invested $2 billion in xAI in January 2026 as part of a $20 billion funding round. So, Tesla shareholders watching Tesla go down in stock price, revenue and vehicle sales saw Musk write a $2 billion check into his AI startup.

The pattern across these transactions is consistent. Musk moved a cash-burning, debt-laden social media platform from his personal balance sheet through xAI, then into SpaceX, where it became part of a company going public. Each step was legal. Each step also passed losses from entities where accountability was limited (private companies, Musk personally) to entities where accountability is distributed (public shareholders and now retail investors). The accumulated deficit on SpaceX's books currently stands at $41.3 billion.

Now the important lockup question. In a typical IPO, all early investors are locked out of selling for 180 days. SpaceX is doing something structurally different. Existing investors (venture funds, early backers who have held for years, including xAI and X investors who just had their stakes converted into SpaceX shares) can begin selling 20% of their holdings as early as two days after SpaceX reports its first quarterly earnings as a public company, likely in August. Further tranches unlock at 70, 90, 105, 120, and 135 days post-IPO, at 7% each time. Musk himself is locked for a full 366 days.

So the timeline looks like this: index funds mechanically buy the stock in the first 15 days, pushing the price up. That creates a window where Musk's early backers, some of whom have been holding since SpaceX was worth a fraction of today's valuation and Twitter investors who watched their stake lose value for three years, are now all sitting on SpaceX shares. The IPO, and the index fund buying wave it triggers, gives them a clean, liquid, high-priced exit.

The Bottom Line

SpaceX is one of the most genuinely impressive companies ever built. Starlink is profitable, growing and has no real orbital competitor. Falcon 9 controls 60% of the global launch market. Starship, if it works at scale, changes the economics of space access entirely (reusable rockets, space-based infrastructure, interplanetary access and many more..).

But the SpaceX IPO is not just a rocket company going public. It is a company that absorbed a cash-burning AI startup, which itself had absorbed a cash-burning social media platform, four months before its listing date. The losses of those acquisitions are now on the balance sheet of a company asking public investors to pay 94 times annual sales based on projections that require 100x growth in five years from an AI division that currently operates at a $2.5 billion quarterly loss.

The index funds will buy automatically. The insiders can start selling in August. The retail investors holding at $135 are in between those two forces.

If you buy SPCX at $135, you are not buying Starlink. You are buying Goldman Sachs's forecast for a $322 billion AI business that does not yet exist, at a price that assumes it will.

That is either the greatest bet of the decade, or the most expensive lesson the retail market has ever been invited to learn.

The choice is yours. It always is.
