SpaceX's stock collapse is sending a stark message to the tech industry: investors are no longer willing to take AI ambitions on faith. The company's shares have plummeted nearly 50% from their June peak of $201.80, closing Friday at $115.07, and Morgan Stanley analysts warn that a further slide to $100 would mean the market is assigning zero or even negative value to SpaceX's entire artificial intelligence business, including its Grok chatbot and stake in coding tool Cursor.

The reversal is staggering in scale. SpaceX raised a record $86 billion through its June initial public offering at $135 per share, pushing the company's market capitalization to roughly $3 trillion at its peak. Since then, the stock has lost approximately $1 trillion in market value, erasing nearly all of the early euphoria that surrounded the debut.

Why Is SpaceX's AI Business Being Valued at Nothing?

Morgan Stanley analyst Adam Jonas laid out the math directly in his analysis. He noted that most investors significantly discount Grok and Cursor, with many assigning zero or even negative value to the AI segment given the high capital expenditure requirements relative to SpaceX's core space and connectivity businesses, combined with uncertain economics and the substantial management time devoted to AI development.

The disconnect is particularly striking because SpaceX made an ambitious claim in its regulatory filing: the company stated it believed it was "the only company with a commercially viable path to building orbital AI compute at scale." SpaceX estimated its total addressable market at roughly $41.5 trillion, with AI products and services accounting for approximately $38.6 trillion of that figure.

Yet despite these projections, public market investors are increasingly skeptical. The gap between SpaceX's internal valuation of its AI opportunity and what the market is willing to pay reveals a fundamental problem: investors want proof that AI investment translates into measurable value, not just impressive technology or ambitious market size estimates.

What Broader Market Trends Are Driving This Selloff?

SpaceX's decline is not happening in isolation. It reflects a wider rotation among investors away from technology firms that have committed hundreds of billions of dollars to AI infrastructure spending. This pattern extends across the sector, affecting companies like Tesla and Alphabet, which have also experienced earnings-related selloffs this week.

Several factors are compounding the pressure on SpaceX specifically:

• Macroeconomic Headwinds: A shaky macroeconomic backdrop combined with elevated tensions between the U.S. and Iran have pushed oil prices higher, fueling inflation concerns and souring risk appetite broadly across markets.
• Massive Share Lockup Expiration: Only about 5% of SpaceX shares became available for public trading at the initial public offering, but up to 911.5 million additional shares could become eligible for sale once lockup restrictions begin lifting around August 6, creating an expected supply increase that many investors believe will continue pushing the stock downward.
• Investor Skepticism on AI Returns: The market is increasingly demanding clear evidence that AI spending converts to actual financial returns, rather than accepting ambitious projections or technological breakthroughs as sufficient justification for valuations.

"Most investors we speak with significantly discount Grok and Cursor. Many ascribe zero or even negative value for AI given the high capex requirements relative to Space and Connectivity, largely uncertain economics, and the high degree of management time devoted to the business," noted Adam Jonas, analyst at Morgan Stanley.

How Should Companies Evaluate Their Own AI Investments?

SpaceX's stock decline offers a real-time lesson for businesses evaluating their own artificial intelligence strategies. The market's skepticism toward SpaceX, despite Elon Musk's track record and the company's genuine technical credibility, suggests that investors are applying stricter standards to AI spending across the board.

• Demand Clear Economic Justification: Companies should articulate how AI investments will generate measurable returns within a defined timeframe, rather than relying on market size projections or technological capabilities alone to justify spending.
• Separate Core Business from AI Bets: Investors appear to be valuing AI segments independently from core business operations. Companies should be prepared to explain how AI contributes to profitability and competitive advantage distinct from their primary revenue streams.
• Prepare for Increased Scrutiny: If public markets are increasingly discounting AI ambitions that lack clear near-term economic justification, expect that same scrutiny to filter down to private company valuations and vendor selection criteria in enterprise software and services.

Morgan Stanley analyst Jonas holds a $300 price target on SpaceX stock, with more than half of that target attributed specifically to the AI segment. Even at that level, the valuation reflects significant skepticism compared to the company's original public offering price and peak valuation.

The broader implication is clear: the era of AI spending justified primarily by technological ambition or massive addressable market estimates may be ending. Companies across the technology sector will face increasing pressure to demonstrate that their artificial intelligence investments are generating tangible business value, not just impressive capabilities or future potential.
