SpaceX Just Had the Largest IPO in History. Was the $1.77 Trillion Valuation Justified?

What Just Happened

Space Exploration Technologies Corporation went public on June 12 2026. The SPCX ticker Nasdaq was trading at $135 per share. That price valued the company at about $1.77 trillion and the deal itself raised $75 billion more than tripling Alibaba's 2014 record to become the largest initial public offering ever completed. Goldman Sachs led the underwriting. MorganStanley Bank of America Citigroup and JPMorgan Chase completed the syndicate. First-day volume was close to 500 million shares in the same range as Facebook's debut in 2012. Unlike Facebook SpaceX did not stumble. The stock closed its first session at $161 an increase of 19 percent pushing the market capitalization above $2 trillion. It then continued to rise. Over the next four trading daysSPCX hit an intraday high of $225.64 before the wind faded. By late June the stock had settled near $165 about 27 percent off that high but still 22 percent above its price. I want to sit with that move for a second because a stock that can drop 27 percent in a matter of days and still be up on the IPO is not a stock the market has agreed upon.a price yet. Two other numbers from the filings matter first and foremost. Alphabet announced a stake of about 4.9 percent which at the time of the IPO valuation was worth about $105 billion. Tesla owns 18.99 million shares of SpaceX. And Elon Musk maintained more than 82 percent of the voting power through a dual class share structure the mechanism where some shares have many votes and others have few or none. Public shareholders bought economic exposure to SpaceX. They did not buy a say in how it is managed

What SpaceX Actually Is

If you remove the symbol SpaceX is three separate businesses that share a balance sheet

The first is launch. Falcon 9 Falcon Heavy and the Starship program sell rocket launches to NASA commercial satellite operators and the Department of Defense. SpaceX conducts about 60 percent of the global orbital launch volume a genuinely dominant position based on reusing landing and returning boosters rather than discarding them with each flight

The second and the one that really moves the stock price is Starlink. Starlink is the satellite broadband constellation and is where the profits lie. In 2025 it generated approximately $11.4 billion in revenue 61 percent of the company's total revenue approximately 50 percent more than the previous year's $7.6 billion. By March 2026 it had surpassed 10.3 million active subscribers in160 countries more than double the 4.6 million it had at the end of 2024. The model consists of recurring subscription revenue. Residential plans cost around $120 a month and customer lifetime value is higher specifically in places where terrestrial broadband is poor or non-existent. That detail matters more than it seems. That's why people pay $120 a month for Internet which they could otherwise get for $60

The third company barely existed at the beginning of this year. SpaceX acquired xAI Musk's artificial intelligence company in February 2026 in a deal that valued the combined entity at $1.25 trillion. xAI builds AI infrastructure through its Colossus data centers and deploys AI models under the Grok name which essentially has nothing to do with rockets or satellites as a business.SpaceX in the first quarter of 2026 reached $10.1 billion up from $4.1 billion in the same quarter the previous year and the investment in xAI is a real part of that jump

The xAI Wildcard

I want to spend more time specifically on xAI because I think it's the part of this valuation that receives the least scrutiny relative to the uncertainty it actually adds

Here's a number worth sitting down with. In February 2026 the deal that merged xAI with SpaceX valued the combined company at $1.25 trillion. In the June IPO four months later the market valued the same combined entity plus any operational progress that occurred in between at $1.77 trillion. Divide 1.77 by 1.25 and you get about 1.42 about a 42 percent increase in aboutFour months. Some of that is real progress. Some of it is simply IPO pricing dynamics first-day offerings and a hot market for the deal of the year. I can't clearly separate the two from public information and I'm not sure anyone outside the company can either

What I can say is that xAI is not disclosed as a separate segment which means that an outside investor cannot compare its revenue its margin or its growth rate to the price paid for it as you can actually do with Starlink. All that can be observed is that the capital expenditure line increases sharply indicating that SpaceX is spending real money on building AI infrastructure not that the spending is getting an adequate return yet. And the deal that created this segment was one in theThat Musk sat on both sides of the table as a majority shareholder of SpaceX and founder of xAI. That doesn't mean the price paid is wrong. What it does mean is that the normal control of a related-party transaction an independent board that puts pressure on the price is weaker here than in a company where the CEO doesn't also control 82 percent of the votes

The Bull Case

To defend SpaceX you don't actually need to believe that rocket launches are a big standalone business. You need to believe that Starlink becomes one of the largest Internet service providers on the planet. Full stop

Musk posted on June 15 that SpaceX could reach roughly $1 trillion in revenue by 2030 up from $18.7 billion in 2025. Do the arithmetic before you do anything else with it. It implies roughly a 53-fold increase over five years. I don't think that's a reasonable base case and I doubt most people repeating it think so either. But even at 10 to 15percent of that figure between $100 and $150 billion in revenue by 2030 SpaceX would already be one of the largest revenue-generating companies on the planet. Musk's figure does not need to be correct for the bullish case to remain huge

NewStreet Research initiated coverage with a $165 price target and described SpaceX as in its words at least a 20- to 25-year equity story. There's also a structural tailwind behind all of this that has nothing to do with fundamentals. A change in Nasdaq rules allowing fast-track entry for major IPOs means SpaceX will soon appear inside index funds and 401k plans. That's some buying pressure showing up.regardless of whether anyone making the purchase has an opinion on the economics of Starlink subscribers

The Bear Case

CFRA initiated coverage with a sell rating and a $115 price target citing what they called an extremely ambitious growth strategy lofty valuation expectations and significant capital intensity. Morningstar dropped further valuing the stock at $63 per share and calling it overvalued

analyst	Target price	call
CFRA	$115	Sell
morning star	$63	Overrated
NewStreet investigation	$165	History of 20 to 25 years.

The bear case boils down to three things. First the losses are real not accounting noise: $5 billion in GAAP net losses in 2025 with capital expenditures accelerating rather than stabilizing. Second the governance structure means that public shareholders essentially have no standing to challenge management decisions including the xAI merger that Musk negotiated on both sides. Third and this is the one I find most compelling at current prices they pay about170 dollars per subscriber in annual recurring revenueThat premium only works if subscriber growth continues to increase at double-digit rates for years. If that growth slows even a little the stock will appreciate strongly because much of the value here lies in the growth rate itself and not in current cash flow

SpaceX is a genuinely extraordinary company. Whether this is an extraordinary investment at $165 per share depends entirely on whether Starlink's growth curve holds up long enough to justify a valuation north of $2 trillion for a company that lost $5 billion last year

A Worked Example: Reverse Engineering the 1.77 Trillion Number

Let me try to answer the main question directly with numbers instead of adjectives

The cleanest way I know to sanity check a valuation is to work backwards from it. What does the price imply that it already has to be true and how does that compare to what we can actually observe today?

Start with the multiple the market is paying right now. SpaceX is priced at $1.77 trillion versus $18.7 billion in revenue in 2025. Divide one by the other: 1.77 trillion divided by 18.7 billion is about 94.7 call it about 95 times trailing revenue. A typical low-growth telecom or infrastructure company typically trades at 2 to 4 timesits revenue. SpaceX is priced at more than 20 times that. That gap is not automatically wrong. Fast-growing high-margin companies regularly earn high multiples. But this indicates that the market has already priced in years of growth that have not yet occurred

Let's assume then for the sake of illustration that a mature version of this business once growth slows and the story is proven rather than promised deserves a multiple of about 15 times revenue. That's still rich well above what a telco gets but in the range in which high-margin platform and subscription companies have traded when the market believed growth was durable. Divide 1.77 trillion by 15 andYou get $118 billion. That's the revenue SpaceX would need to generate at that multiple to make the current price fair instead of betting on an even higher multiple in the future

That number is worth dwelling on because it's not random. It falls almost exactly within the $100 to $150 billion range that the bull case is already pointing to 10 to 15 percent of Musk's own $1 trillion 2030 target that analysts consider plausible. In other words the current price does not support Musk's stated ambition.with a 15x earnings multiple almost coincidentally

Now it translates $118 billion into something concrete: subscribers. Starlink's residential plans cost about $120 a month or $1,440 a year. Divide $118 billion by 1,440 and you get roughly 82 million subscribers. Starlink had 10.3 million active subscribers in March 2026. Going from 10.3 million to 82 million is almost eight times the subscriber base for a productwhose main attraction at the moment is to reach places that terrestrial broadband cannot which is a real but naturally limited market

I want to check the same valuation from a second angle because an earnings multiple alone can hide a lot. Let's assume instead that the market is implicitly paying for future earnings using something like a 30 times earnings multiple generous but not unheard of for a company that is believed to have both growth and a durable moat. 1.77 trillion divided by 30 is $59 billion of net income that the company would eventually need to realize. Even with a marginIllustrative net of 25 percent well above the negative margin SpaceX actually posted in 2025 that's $59 billion divided by 0.25 or $236 billion in revenue. That's exactly double what the multiple revenue lens implied and about 12.6 times what SpaceX actually generated in 2025

Focus	Illustrative scenario	Implicit income needed
Multiple income	15x income	118 billion
Multiple wins	30x profit 25% margin	236 billion

Both lenses land in the same place directionally. The current price calls for SpaceX across all three businesses combined to become one of the biggest revenue generators on the planet in the coming years. Starlink can't get there on its current growth curve alone without a significant currently undisclosed contribution from launch and xAI. That's the real bet under the symbol regardless of whether those who bought it at $165 a share could express it exactly in those terms

Case Study: Iridium and the Cost of Being Early

If you want an idea of how badly valuing a satellite infrastructure can go wrong look back to Iridium in the 1990s. It's not a perfect match for Starlink but the mechanism is the same one that bulls and bears argue about today

Motorola and a group of partners spent about $5 billion building a constellation of 66 low-Earth orbit satellites to offer global satellite phone service. The engineering worked. Iridium phones could actually make a call from almost anywhere on the planet's surface a true technical achievement in 1998. What broke the company was not the satellites. It was the gap between the infrastructure that had already been built and paid for and the number of people who actually wanted to pay for it.Iridium filed for bankruptcy in 1999 less than a year after launching the commercial service having spent billions to build something that worked exactly as designed and still couldn't support its own capital structure

The assets were subsequently purchased out of bankruptcy for a small fraction of the original construction cost and the constellation continued to fly under new owners becoming years later a real profitable business under a very different set of expectations

I don't think Starlink is Iridium. Starlink already has over 10 million paid subscribers real revenue and a growth curve that Iridium never came close to. But the mechanism that Iridium illustrates is exactly what the bear case points to. You can build a perfectly functioning satellite network and still lose because the valuation or in the case of Iridium the capital structure behind it assumed a subscriber curve that the real market would not support on the actual available schedule. ThatWhether infrastructure is real and whether infrastructure is adequately monetized are two different questions and the market has a long history of answering the first for years before finishing answering the second

Where the Bull Case Breaks

Let's take the bear case seriously for a minute because I think two of its weaknesses are structural not just sentimental

Start with launch. SpaceX has about 60 percent of the world's orbital launch volume today and that share is doing real work in the bull market case both as revenue and as a delivery mechanism for its own Starlink satellites. But launch is a competitive capital-intensive business not a moat unto itself. Blue Origin's New Glenn is flying. Rocket Lab is growing. China's state-backed launch programs don't stop and the rocket economyReusable rockets the innovation that gave SpaceX its cost advantage in the first place are no longer unique to SpaceX. A 60 percent stake earned when you were the only credible reusable rocket company is a different asset than a 60 percent stake defended against three or four credible competitors at a time

Then there's the part of Starlink's economics that gets less attention: the satellites don't last forever. Starlink satellites operate in low-Earth orbit and low-Earth orbit satellites have a limited lifespan reportedly running on the order of five years before they need to be replaced. That means Starlink isn't a one-time build business like a fiber network or a toll road. It's closer to a treadmill. Every satellite that currently generates revenue is also a liability with acountdown and the company has to keep launching indefinitely just to keep the constellation at its current size before spending a dollar to grow it even more. That replacement capital expenditure is built into the business permanently in a way that a one-time infrastructure build is not

Finally think carefully about who Starlink's best customers really are. The $120-a-month subscriber who gladly pays is almost by definition someone who doesn't have a good terrestrial alternative which usually means someone who lives in a rural or remote area. Those customers have a high willingness to pay and a high margin per subscriber but they are dispersed over a huge geography and each additional one adds relatively little to what a single satellite pass can do. If Starlink wants to continueBy growing subscribers at a similar pace as recently it will eventually have to reach further into suburban and urban markets where it competes directly with fiber cable and 5G fixed wireless all of which are typically cheaper. Growth in that segment is likely accompanied by lower average revenue per user not the same $120 which is a very different growth story than what is considered today

Pile the bearish case governance point on top of all this. Musk controls more than 82 percent of the votes. He was on both sides of the deal that merged xAI with SpaceX at a valuation of $1.25 trillion four months before the IPO priced the combined company at $1.77 trillion. If launch competition compresses margins or replacement capital spending eats into Starlink's cash generation or subscriber mix shifts towardIn lower ARPU markets public shareholders essentially have no mechanism to reject how management responds. They are underwriting operational risk and capital allocation risk at the same time without any vote that matters

How I'd Actually Read This Stock

This is how I would really think about SPCX and I want to be clear that this is my reading not a recommendation to buy or sell anything

I wouldn't treat it as a single stock. I would treat it as three separate subscription questions stapled onto a single ticker because that's what it is. In fact I can model Starlink imperfectly with subscriber counts ARPU and a growth curve that I can look at quarter by quarter which is exactly what I did in the example above. I would treat the launch more as a question of market share and margin than as a question of growth since revenue is not broken out separately and the fieldCompetitive is getting busier not less

The one data point I would watch more closely going forward is Starlink's subscriber growth relative to the previous quarter along with any signs of how ARPU moves as the subscriber base grows into denser markets. That's the number that decides whether the 82 million subscriber figure from my worked example is a ten-year story or a twenty-five-year story and the gap between those two timelines is most of what separates the bull case from the bear case here

I also pay attention to how wide the analysts' price targets are because dispersion is information. Morningstar at $63 and NewStreet at $165 are more than 2.6 times apart in the same company using the same public filings. It's not a matter of analysts disagreeing over a few margin points. That is professionals analyzing the same numbers and coming to really different conclusions about which of SpaceX's three businesses defines the multiple. When I see adifference so wide my honest reaction is to not split the difference and assume the truth lies in the middle. It's to admit that the range of outcomes is still that wide open and that anyone who tells you they know exactly where this lies is telling you more about their beliefs than about the company

If I were building a mental model instead of a position I would spend my time on Starlink's unit economics first and foremost because it's the only one of the three businesses where I can actually verify my work

The Bottom Line

SpaceX is priced at $1.77 trillion on $18.7 billion of revenue a multiple that only makes sense if you believe the company is on track to be one of the world's largest revenue generators not the single-segment midsize company its current financials describe. The worked example above turns that belief into something concrete. On a reasonable illustrative revenue multiple SpaceX needs something close to $118 billion of eventual revenue to justify the price.Starlink has already more than doubled its subscriber base in about fifteen months. But it's also not priced in as a sure thing which is exactly why CFRA sees $115 Morningstar sees $63 and NewStreet sees165 for the same company in the same day's filings. Iridium is the reminder that running infrastructure and properly monetizing infrastructure on the timeline the market sets are two different issues and the market has a long history of confusing the former with the latter. Launch faces real and growing competition. Starlink is a replacement capital investment treadmill wrapped in a subscription business and its best customers are the hardest to scale. Voting control of 82 percent ofMusk means that none of this will get a shareholder vote if it goes sideways. My honest answer to the headline's question is that $1.77 trillion is not obviously wrong but it is a price that requires several very big things to get right at once and right now the only one of those things I can verify with real numbers is Starlink
