Can SpaceX grow fast enough to justify its $1.84 trillion valuation?

SpaceX’s record IPO priced in enormous growth

SpaceX’s June IPO raised $75 billion and valued the company at approximately $1.77 trillion, making it the largest public offering in history.

The stock surged during its first week of trading, briefly pushing SpaceX’s market capitalization to around $2.5 trillion and placing it alongside Amazon as one of the five largest listed companies in the world.

The excitement has since cooled, but SpaceX remains valued at roughly $1.84 trillion.

That valuation is striking because the company reported only $18.7 billion in revenue in 2025 and posted a net loss of nearly $5 billion. Investors are therefore placing relatively little weight on present-day earnings. The stock is being priced on expectations for exceptional future growth.

The challenge is determining just how exceptional that growth must be.

Amazon offers a useful comparison

Amazon is often used to justify paying high valuations for businesses capable of reshaping large industries.

The company went public in May 1997 at $18 per share, with a market value of only $438 million. Annual revenue at the time was $148 million, meaning the stock traded at roughly three times sales.

That valuation was expensive for a loss-making online bookseller. It became easier to justify because Amazon was doubling its revenue annually and had the potential to expand far beyond books.

Amazon reached approximately $19.2 billion in annual revenue by 2008, only 11 years after its IPO. By 2025, sales had climbed to $716 billion, putting it alongside Walmart as one of the highest-revenue companies in the US.

From the IPO through 2025, Amazon’s revenue increased almost 5,000-fold. Early investors who held through the dot-com collapse and years of weak earnings were rewarded with returns of roughly 3,300 times their original investment, equivalent to around 32% annually over nearly three decades.

The comparison shows why investors are willing to back ambitious companies. It also highlights how demanding SpaceX’s current valuation already is.

SpaceX is priced far above Amazon at the same revenue level

The differences become clearer when SpaceX is compared with Amazon at a similar level of revenue.

Amazon generated approximately $19.2 billion in revenue in 2008, nearly matching SpaceX’s $18.7 billion in 2025 sales. Amazon’s market capitalization at the time was slightly below $40 billion, placing its price-to-sales ratio just above two.

SpaceX, by comparison, is valued at around $1.84 trillion on almost identical annual revenue.

That gives SpaceX a price-to-sales multiple approaching 100, or roughly 50 times the valuation investors gave Amazon when it reached the same sales level.

SpaceX may deserve a premium because it has unique businesses and major technological advantages. However, a valuation gap of this size requires growth on a scale that few companies have ever achieved.

Starlink provides the strongest current foundation

Starlink is one of the clearest arguments supporting the SpaceX valuation.

The satellite internet business reportedly generates around $4.4 billion in operating income, while revenue has been compounding at approximately 50%.

Starlink gives SpaceX a recurring-revenue business with a growing global customer base. It also has strategic value in remote communications, defense, aviation, maritime connectivity and direct-to-device services.

However, there are early signs that the growth profile is becoming less straightforward. Revenue growth is slowing as the business becomes larger, while average revenue per customer is declining.

Falling customer revenue may be manageable if subscriber growth remains strong and launch costs continue to decline. But it means Starlink will need greater scale to maintain the same overall growth rate.

Launch dominance remains a major advantage

SpaceX also controls more than half of global orbital rocket launches.

Its reusable rocket technology gives the company a cost and frequency advantage that competitors have struggled to match. That dominance supports Starlink deployment and creates revenue from commercial, government and defense customers.

Starship could extend that advantage by allowing SpaceX to place much larger payloads into orbit at a lower cost.

But competition is increasing. Blue Origin and other well-funded rivals are investing heavily in reusable launch systems and broader space infrastructure.

SpaceX may remain the market leader, but the current valuation assumes that its launch advantage persists for many years and produces substantial pricing power.

xAI adds potential and uncertainty

The merger with xAI added artificial intelligence to the SpaceX growth story.

In the most optimistic scenario, SpaceX could combine launch capacity, satellites, communications infrastructure, computing resources and AI models into a vertically integrated technology platform.

That could create opportunities in data centers, defense systems, robotics, autonomous operations and orbital computing.

However, xAI remains behind major competitors in several areas. OpenAI, Anthropic and Google’s Gemini have established positions in advanced AI models, while new open-source systems continue to improve quickly.

The AI business therefore expands SpaceX’s potential market, but it also adds spending, competition and execution risk.

What a 20% annual return would require

One way to assess the valuation is to work backward from the return investors may expect.

Assume SpaceX shareholders demand an annual return of 20% over the next decade. That is ambitious, but still below the roughly 32% annual return Amazon generated following its IPO.

At 20% annual compounding, SpaceX’s market capitalization would need to rise from $1.84 trillion to around $11.4 trillion by mid-2036.

Assuming no additional share issuance, that would imply a stock price near $860.

The amount of revenue SpaceX would need in 2036 depends on the price-to-sales multiple investors are willing to pay at that point.

Scenario one: SpaceX matures like Amazon

Amazon currently trades at approximately 3.7 times trailing sales.

If SpaceX eventually receives the same mature valuation, an $11.4 trillion market capitalization would require annual revenue of about $3.1 trillion in 2036.

That is comparable to the entire economic output of France and equal to roughly one-tenth of current US GDP.

To grow from $18.7 billion to $3.1 trillion in ten years, SpaceX revenue would need to compound at approximately 67% annually.

Sustaining that pace from an already large revenue base would be almost without precedent.

Scenario two: SpaceX keeps a premium valuation

A more generous scenario assumes investors continue valuing SpaceX at 20 times annual sales in 2036.

At that multiple, the company would need approximately $570 billion in annual revenue to support an $11.4 trillion market capitalization.

That is about three-quarters of Amazon’s 2025 revenue. Amazon required almost three decades to reach its current scale.

For SpaceX to reach $570 billion within ten years, revenue would need to grow by approximately 41% annually.

That target is lower than the first scenario, but still extremely demanding.

A 20-times-sales multiple would remain exceptional

A mature company trading at 20 times sales would still carry one of the highest valuations in the market.

Among the 20 largest US companies, Broadcom and Nvidia are among the few trading above that level, with price-to-sales ratios around 29.2 and 24.9 respectively. Both businesses generate large profits and have delivered rapid growth.

A high sales multiple is difficult to sustain because revenue is not profit. Companies must still pay operating expenses, salaries, taxes, research costs and capital expenditure.

For SpaceX to retain a 20-times-sales valuation in 2036, investors would need to believe its growth, market position and margins remained extraordinary even after the company had become one of the largest businesses in history.

Amazon’s fastest growth started from a much smaller base

Amazon’s strongest ten-year period of revenue expansion came between 1997 and 2007, when sales grew at an annual rate of roughly 59%.

But Amazon began that period with only $148 million in revenue.

SpaceX starts with $18.7 billion, a base approximately 126 times larger. Maintaining a high growth rate becomes progressively more difficult as revenue expands because each percentage point requires a much larger dollar increase.

A 50% rise from $148 million requires less than $75 million in additional sales. A 50% rise from $18.7 billion requires more than $9 billion.

This scale problem is why only a small number of companies have sustained annual growth above 40% for a full decade.

Musk’s $1 trillion target raises the bar further

Elon Musk has suggested SpaceX could generate approximately $1 trillion in annual revenue by 2030.

Moving from $18.7 billion in 2025 to $1 trillion five years later would represent an increase of more than 53 times. It would require annual revenue growth of roughly 122%.

That pace would be more than double Amazon’s strongest ten-year growth rate, beginning from a base thousands of times larger than Amazon’s IPO revenue.

Even if SpaceX achieves the $1 trillion target, the investor return would still depend heavily on its valuation multiple.

At Amazon’s current 3.7-times-sales multiple, $1 trillion in revenue would support a market value near $3.7 trillion. That would produce an annualized return of around 17% from SpaceX’s current valuation.

At 20 times sales, the same revenue would imply a $20 trillion valuation and annual returns approaching 70%.

The wide range shows how sensitive the investment case is to assumptions that cannot be known today.

Wall Street’s forecasts are far below Musk’s

Even the more optimistic forecasts from SpaceX’s IPO banks remain well below Musk’s target.

Morgan Stanley expects SpaceX to generate roughly $330 billion in revenue by 2030, while Goldman Sachs projects around $470 billion.

Both forecasts imply dramatic growth from 2025 levels, but remain well below the $1 trillion suggested by Musk.

Analyst price targets also reveal the uncertainty. Published estimates range from a cautious fair value of $63 to a bullish target of $401. New Street Research set a target of $165 while noting that investors may need a 20- to 25-year horizon for the valuation to work.

Such a wide range reflects the difficulty of valuing a company whose future depends on several businesses with very different risk profiles.

SpaceX can succeed without rewarding shareholders equally

SpaceX can become a highly successful company and still deliver disappointing stock-market returns.

The distinction matters because the quality of a business and the attractiveness of its share price are not always the same.

Amazon generated exceptional shareholder wealth partly because it began with a valuation of only $438 million. SpaceX is attempting to compound from $1.84 trillion, making each additional doubling far more difficult.

To justify the current price and deliver strong long-term returns, SpaceX must sustain historically unusual growth across Starlink, launch services and AI while protecting its competitive advantages and eventually producing substantial profits.
