Houston, We Have a Valuation Problem: Why SpaceX's IPO Price Doesn't Add Up

Houston, We Have a Valuation Problem: Why SpaceX's IPO Price Doesn't Add Up

SpaceX is preparing to go public, and the excitement is running hot. Reusable rockets, a fast-growing satellite internet business, and big ambitions in AI have created a powerful story. The proposed IPO price of $135 per share would value the company at roughly $1.8 trillion.

That number looks impressive on a slide. Whether it makes sense is a different question.

Valuation expert Aswath Damodaran revisited his analysis after the company released its full prospectus in May 2026. His conclusion is clear: the equity value sits closer to $1.3 trillion, or roughly $100 per share. That is still a very large number. It is also well below where the IPO is being priced.

The gap between the proposed price and a more disciplined valuation is not small. It raises a simple but important question for anyone thinking about buying the stock: are you paying for what the company has already achieved, or are you paying for a very optimistic version of what it might achieve years from now?

The Business Has Real Parts

SpaceX operates in three areas, and they are not equally mature or equally certain.

The launch business is the most proven part of the company. Reusable rockets have created a real and measurable cost advantage over traditional expendable rockets. This segment generates solid gross margins and has consistent demand from governments, defense agencies, and commercial satellite operators. It is the foundation that made everything else possible. However, growth here is steadier rather than explosive, and competition is gradually increasing as other players improve their own technology.

Starlink is currently the main growth driver. Subscriber numbers have grown quickly over the past year, and unit economics are improving as the satellite constellation becomes denser and more efficient. For many users in remote or underserved regions, Starlink represents the first reliable internet connection they have ever had. This part of the business is doing real work today and is already contributing meaningful revenue. At the same time, average revenue per user has come under some pressure as the service expands into more price-sensitive markets. The long-term success of Starlink will depend on whether the company can maintain healthy margins while continuing to grow the subscriber base against increasing competition.

The AI and compute infrastructure bets are the newest and least certain part of the story. There is clear demand for specialized high-performance computing capacity, especially from companies building large AI models. SpaceX is positioning itself in this area through its own infrastructure and related ventures. This segment carries the highest upside potential, but it also carries the highest execution risk. Competition is intense, capital requirements are very large, and margins in this business are far from guaranteed. Many assumptions about future market share and pricing power in this segment remain unproven.

All three areas can succeed in different ways. That is not the main debate. The real debate is what price makes sense while waiting to see which parts deliver and which ones fall short.

The Gap Between Story and Price

Damodaran’s updated valuation puts the equity value at approximately $1.3 trillion, or about $100 per share. The proposed IPO price of $135 per share implies a valuation of $1.8 trillion.

That is a meaningful difference.

The higher price assumes several things at once. It assumes strong revenue growth across multiple segments for many years. It assumes that margins in both Starlink and the newer AI-related businesses will remain high even as competition increases. It assumes that the company can continue to invest heavily in new rockets, satellites, and compute infrastructure without creating too much dilution or financial strain. And it assumes that execution across these complex programs will remain relatively smooth.

These are optimistic assumptions. They may turn out to be correct. But they are not free. When you pay a very high price for future success, you are effectively betting that almost nothing will go wrong along the way. History shows that ambitious technology companies rarely follow a perfectly smooth path for long periods of time.

The lower valuation reflects a more cautious view. It gives the company credit for its real achievements in launch and Starlink while applying more conservative assumptions about how quickly the newer businesses can scale and how profitable they will ultimately be. It also takes into account the significant ongoing capital needs of the business. This approach does not dismiss the potential of SpaceX. It simply refuses to assume that everything will work out exactly as hoped.

Governance Is Part of the Price

One factor that receives less attention than it should is governance and control.

Elon Musk holds more than 85% of the voting power through a special share structure. This structure has allowed fast decisions and ambitious projects that might have moved more slowly under more traditional governance. It has also created a situation where outside shareholders have limited influence if priorities shift or if capital allocation decisions favor other ventures in which Musk is involved.

For a company that still needs to invest heavily across several fronts at the same time, concentrated control is not a minor detail. It affects how risk is managed and how capital is allocated over time. Investors who buy at a high valuation are effectively accepting this governance structure as part of the deal. If things go well, the structure may not matter much. If things become more difficult, the lack of checks and balances could become more relevant than many buyers currently assume.

This does not make SpaceX a bad business. It does mean that the margin of safety is thinner than it would be in a company with more balanced governance.

What Actually Matters for Investors

SpaceX has delivered tangible progress. Lower launch costs and a growing global network are real achievements that deserve recognition. The question for new investors is not whether the company has potential. The question is whether that potential is already fully priced in at the proposed IPO level.

At $135 per share, the margin of safety is thin. If growth slows in any major segment, if margins come under more pressure than expected, or if execution across multiple complex programs proves more difficult than hoped, there is not much room for disappointment. Investors would be relying almost entirely on continued strong execution and favorable market conditions for many years.

This is not an argument against owning the business in principle. It is an argument against paying a price that leaves almost no room for normal business outcomes. Good investing is not only about finding companies with strong prospects. It is also about paying a price that gives you some protection when things do not go exactly according to plan.

What Regular Investors Should Do

Most people have two reasonable options when it comes to this IPO.

The first is to wait and observe. Watch how the stock trades once it becomes public. See what the actual quarterly results look like without the IPO marketing and roadshow enthusiasm. See how the market reacts when the story meets real financial numbers over time. Many companies look different after the initial excitement fades.

The second option is to wait for a better price. If the stock declines after the IPO, which has happened with many highly anticipated offerings in the past, and it moves closer to levels supported by more conservative assumptions, then it becomes worth serious consideration. Not because the underlying business has changed, but because the price finally offers some protection against normal business risks.

Buying at the peak of excitement simply because the story feels inevitable is not a disciplined investment approach. It is participating in a narrative. Narratives can be powerful, but they do not protect capital when reality turns out to be more complicated than expected.

For most ordinary investors, patience is likely to be the better strategy in this case. There is no requirement to participate in every large IPO. The companies that create the most long-term value for shareholders are not always the ones that launch at the highest valuations.

The Bottom Line

 

SpaceX has real technology and real momentum in important areas. That part of the story is not in dispute. The company has achieved things that many people once thought were impossible or decades away.

What is in dispute is whether $1.8 trillion is the right price to pay for that momentum today. Careful, numbers-based analysis suggests it is not. The gap between the proposed IPO price and more grounded valuations is large enough that it deserves serious attention from anyone thinking about buying the stock.

For my part, I would wait. On a calculated fair value of around $100 per share, I would want to see a clear margin of safety before considering a position. That would put my personal buy zone closer to $50 per share or lower. At the proposed IPO price of $135, that margin of safety simply does not exist.

Sometimes the best move an investor can make is to let the rocket launch without being on board at the asking price. The business may still succeed over time. The question is whether new investors at the current proposed valuation will be properly compensated for the risks they are taking.

Good investing often comes down to one simple discipline: refusing to pay prices that assume almost everything will go right. In the case of this IPO, that discipline points toward patience rather than participation at the current price.

This is not financial advice. It is one investor’s view based on the information available today. Every person should do their own analysis and make decisions that fit their own risk tolerance and time horizon.
