The Cost of Doubt: Why Shorting SpaceX Is Prohibitively Expensive

Michael Burry, the investor immortalized for foreseeing the 2008 financial collapse, recently made a revealing admission. On his Substack, he stated he holds neither a long nor a short position in SpaceX. Surprisingly, this stance isn't primarily a fundamental critique of the company, but a pragmatic reaction to a harsh market truth: the cost of betting against Elon Musk's aerospace venture has skyrocketed to prohibitive levels.

Deconstructing the SpaceX Empire

Burry offered a fragmented view of SpaceX's business model. He describes it not as a unified aerospace leader, but as a composite of four distinct entities: a modest-scale space exploration firm, a niche telecommunications operator, a struggling social media platform (referring to X), and a computing power service provider—a model he compares to, but sees as lesser than, AI infrastructure firm CoreWeave.

"The central issue is the staggering numerical disconnect," Burry noted. "A company generating under $20 billion in annual revenue commands a market valuation approaching $3 trillion. Historically, such a vast gap often signals speculative excess."

Market Frenzy vs. Skeptical Reality

These comments emerge as SpaceX's stock continues its meteoric rise post-IPO. Shares soared 20% on the first trading day and climbed over 25% in the following week, propelling its market capitalization to dizzying heights.

  • Its valuation has now surpassed Warren Buffett's Berkshire Hathaway.
  • It entered the top five most valuable companies globally, trailing only Nvidia, Google, Apple, and Microsoft.
  • This investor euphoria has inflated prices to unprecedented levels.

This frenzy has driven the price of put options—instruments for betting on a price decline—to extreme premiums, creating a formidable financial barrier for would-be short sellers. Burry's reluctance underscores a critical market paradox: even the most convinced skeptics can be sidelined by sheer transaction cost. The debate thus shifts from SpaceX's intrinsic worth to how market mechanics can amplify or suppress dissent during periods of intense speculation.
