Synopsis : SpaceX’s upcoming IPO has attracted enormous investor interest, but not everyone is convinced. Steve Eisman, the investor famous for predicting the 2008 housing crash, believes the company’s future is increasingly dependent on artificial intelligence rather than its traditional space and satellite businesses.
SpaceX IPO Faces Skepticism From Steve Eisman
As SpaceX prepares for what could become the largest IPO in history, veteran investor Steve Eisman has emerged as one of its most notable critics.
The company is expected to raise between $75 billion and $80 billion at a valuation of roughly $1.75 trillion, drawing massive global attention. However, Eisman says he is staying on the sidelines and has serious concerns about the company’s financial profile and long-term investment case.
Capital Spending Has Exploded
One of Eisman’s biggest concerns is the rapid rise in SpaceX’s capital expenditure.
According to his analysis of the IPO filing, capital expenditure represented around 42% of revenue in fiscal 2023. In the most recent quarter, that figure reportedly surged to more than 200% of revenue.
This sharp increase suggests the company is spending heavily on infrastructure, expansion, and future growth initiatives, raising questions about profitability and capital efficiency.
AI Is Becoming The Core Story
Eisman argues that investors may believe they are buying into a space exploration company, but the investment narrative is increasingly centered around artificial intelligence.
According to him, SpaceX is evolving beyond rockets, satellite launches, and Starlink internet services. Instead, a growing portion of its future growth expectations is tied to AI infrastructure, data centers, and advanced computing capabilities.
This shift, he believes, significantly changes the risk profile of the business.
Grok Fails To Impress
A major part of SpaceX’s AI ambitions comes through xAI and its chatbot Grok.
However, Eisman remains unconvinced about the platform’s competitive position.
He believes Grok is not currently viewed as a leading-edge AI product compared to other major players in the industry. As a result, he questions whether the enormous investments being made today can generate sufficient long-term returns.
AI Industry Becoming Increasingly Competitive
Beyond SpaceX specifically, Eisman also expressed broader concerns about the AI sector.
According to him, technology companies are collectively spending hundreds of billions of dollars on AI infrastructure and data centers. However, many AI products are beginning to look increasingly similar, reducing differentiation and competitive advantages.
He argues that the sector risks becoming commoditized, where enormous investments may not necessarily translate into sustainable profits.
Prospectus Reads Like Science Fiction
Eisman also highlighted some of SpaceX’s ambitious long-term goals.
The IPO filing discusses future opportunities such as asteroid mining, large-scale space infrastructure, and humanity’s expansion beyond Earth.
While these ambitions capture investor imagination, Eisman believes they add another layer of uncertainty to an already complex investment story.
AI Division Continues To Generate Losses
According to reported figures, SpaceX’s AI-related operations generated approximately $3.2 billion in revenue during 2025 but recorded operating losses of around $6.4 billion.
Despite securing major computing agreements and enterprise partnerships, the AI business remains deeply loss-making and requires significant ongoing investment.
This raises questions about when, or if, these operations can become meaningfully profitable.
Investors May Be Betting On AI, Not Space
Eisman believes the market increasingly values SpaceX based on future AI opportunities rather than its traditional businesses.
While Starlink and launch services remain important revenue contributors, the company’s long-term projections suggest that artificial intelligence represents the largest growth opportunity within its overall addressable market.
In his view, investors need to recognize that they are effectively making a long-term bet on AI execution rather than solely on space exploration.
Valuation Remains A Key Concern
The proposed valuation of approximately $1.75 trillion is another major sticking point.
Eisman argues that the valuation implies exceptionally high expectations for future growth. Compared to many established technology companies, the pricing leaves little room for operational disappointments or slower-than-expected execution.
As a result, he believes investor enthusiasm may be running ahead of underlying financial fundamentals.
Conclusion
While SpaceX remains one of the world's most innovative companies, Steve Eisman believes investors should carefully evaluate the risks behind the excitement. Rising capital expenditure, ongoing AI losses, intense competition, governance concerns, and a premium valuation all contribute to his cautious stance.
As the company prepares for its historic market debut, the debate continues over whether investors are buying into the future of space exploration—or the future of artificial intelligence.
