The Big Short 2.0: Michael Burry Targets Caterpillar in a High-Stakes Bet Against the AI Infrastructure Boom

By Financial Correspondent

In the volatile landscape of modern finance, few names carry as much weight—or spark as much controversy—as Michael Burry. The hedge fund manager, immortalized in Michael Lewis’s The Big Short for his clairvoyant and highly profitable bet against the 2008 subprime mortgage crisis, has revealed his latest target. This time, however, he isn’t betting against the housing market; he is taking a massive short position against Caterpillar Inc., the century-old industrial titan that has recently found itself rebranded as a darling of the Artificial Intelligence (AI) revolution.

Burry’s move signals a profound skepticism regarding the sustainability of the current market rally. While the broader indices have been propelled to record highs by the promise of generative AI, Burry views the meteoric rise of companies like Caterpillar not as a sign of fundamental industrial strength, but as a symptom of a speculative bubble reminiscent of the 1999-2000 dot-com era.

Main Facts: The Short Position and Market Reaction

Michael Burry, through his investment vehicle, has initiated a significant short position against Caterpillar (NYSE: CAT). The trade was disclosed following a period of unprecedented growth for the heavy-machinery giant. Historically known for its iconic yellow excavators and bulldozers, Caterpillar’s stock has surged by more than 100% over the past year, recently eclipsing the $1,000-per-share mark—a valuation previously unthinkable for a traditional industrial manufacturer.

Burry disclosed that he shorted the stock at an entry price of $1,060.98 per share on a Tuesday in late June. The market’s reaction was swift. By Wednesday’s close, Caterpillar shares had retreated nearly 7%. The downward momentum continued into Thursday, with shares falling an additional 4% to reach approximately $949. This represented the stock’s lowest point since mid-June, momentarily vindicating Burry’s bearish stance.

The core of Burry’s argument rests on valuation metrics. He points to the company’s price-to-sales (P/S) ratio, which has reached its highest level in three decades. For a cyclical company like Caterpillar, such a premium suggests that investors are pricing in a level of perpetual, high-margin growth that may not be supported by the realities of the global construction and mining sectors.

Chronology: The Making of an "AI Darling"

To understand why Burry is betting against Caterpillar, one must look at the timeline of the stock’s transformation.

• 2023 – Early 2024: Caterpillar benefits from a post-pandemic infrastructure surge, fueled by the U.S. Infrastructure Investment and Jobs Act. The stock maintains steady growth as traditional construction demand remains resilient.
• February 2024: Market sentiment shifts. Analysts begin to link Caterpillar’s "Energy & Transportation" segment to the burgeoning AI sector. Specifically, the demand for large-scale data centers—the "brains" of AI—requires massive amounts of reliable, on-site backup power.
• May 2024: Burry begins issuing public warnings. On social media and through his Substack, he suggests that the current market euphoria "feels like the last months of the 1999-2000 bubble." He begins refreshing shorts against semiconductor ETFs (SOXX) and high-flying tech names like Tesla and Nvidia.
• June 2024: Caterpillar’s stock price hits an all-time high, surpassing $1,000. The rally is driven by reports that AI "hyperscalers" (Google, Microsoft, Amazon) are ordering diesel and natural gas generators in record numbers to secure their power grids.
• Late June 2026 (Current Reporting Period): Burry officially enters his Caterpillar short at $1,060.98, citing extreme overvaluation and a belief that the AI-driven "pick and shovel" play has gone too far.

Supporting Data: The Fundamentals vs. The Hype

The data surrounding Caterpillar presents a tale of two companies. On one hand, the financial performance is objectively strong. In the first quarter of the year, Caterpillar reported sales of $17.4 billion, a 22% increase year-over-year. This performance comfortably beat Wall Street expectations and highlighted the company’s ability to maintain pricing power despite inflationary pressures.

However, Burry’s concern lies in the source of this growth and the multiple the market is willing to pay for it.

1. The Price-to-Sales Anomaly: Caterpillar’s P/S ratio is currently at a 30-year peak. Historically, industrial stocks trade at 1x to 1.5x sales. The current valuation suggests the market is treating Caterpillar like a high-growth SaaS (Software as a Service) company rather than a capital-intensive manufacturer.
2. Sector Overextension: The surge in Caterpillar’s stock (up 172% over 12 months) mirrors the "secondary AI play" trend. Other beneficiaries include GE Vernova (up 60% YTD) and Vertiv Holdings (up 70% YTD). Burry argues that these companies are being swept up in a "rising tide" that ignores the cyclical risks inherent in hardware and infrastructure.
3. Inventory Levels: While dealer inventories have improved, any slowdown in global construction or a pivot in AI capital expenditure (CapEx) could lead to a rapid buildup of unsold machinery, squeezing margins.

Official Responses: The Bull Case from the Analysts

Not all market participants share Burry’s grim outlook. Sergey Glinyanov, a senior analyst at Freedom Broker, provides a robust counter-narrative. According to Glinyanov, Burry may be misinterpreting the "AI hype" as a temporary fad rather than a permanent structural shift in global infrastructure.

"A structural theme is emerging," Glinyanov told Fortune. He argues that the electrical grid in the United States and Europe is aging and increasingly incapable of handling the "soaring energy needs" of modern AI campuses. "As developers build bigger and bigger AI campuses, they are increasingly seeking out the diesel and natural-gas generator power systems that Caterpillar sells to secure reliable power."

From Glinyanov’s perspective, Caterpillar is not just selling tractors; it is selling "energy security." This positioning allows the company to capture a larger share of the massive CapEx budgets of tech giants. Furthermore, Glinyanov notes that Caterpillar’s traditional business—selling mining and construction equipment—remains healthy, providing a "margin of safety" that tech-only companies lack.

However, even the bulls are cautious. Freedom Broker has set a price target of $910 for Caterpillar, which actually implies a near-term pullback from the $1,000+ highs. This suggests that while they believe in the long-term story, they acknowledge that the stock may have moved "too far, too fast."

Implications: A Litmus Test for the AI Revolution

Michael Burry’s short of Caterpillar is more than just a single trade; it is a litmus test for the entire "AI infrastructure" investment thesis. The implications of this battle between Burry and the market bulls are significant:

1. The "Hyperscaler" Dependency

Caterpillar’s current valuation is tethered to the spending habits of a handful of tech giants. If companies like Microsoft or Meta decide to scale back their data center investments due to diminishing returns on AI software, the demand for Caterpillar’s power systems could evaporate. As Glinyanov warned, "Should we observe deterioration in hyperscalers’ fundamentals—particularly cash flow generation or debt burden—multiples could face a meaningful pullback."

2. The Return of Value Investing

For years, value investors have been sidelined by the growth-at-any-price mantra of the Silicon Valley era. Burry’s move is a high-profile attempt to reassert the importance of valuation metrics. If his short succeeds, it could trigger a broader rotation out of "AI-adjacent" industrial stocks and back into undervalued sectors, or simply into cash.

3. The Validity of the "Grid Collapse" Narrative

The bull case for Caterpillar relies on the assumption that the public electrical grid will remain inadequate, forcing private companies to rely on Caterpillar’s generators. If government-led grid modernization efforts accelerate, or if new energy storage technologies (like large-scale batteries) become more cost-effective than diesel generators, Caterpillar’s "AI advantage" could be neutralized.

4. Burry’s Reputation

Michael Burry has a history of being "early" to his calls. In the mid-2000s, he sat on his housing shorts for years while facing immense pressure from his own investors. In the current market, his reputation as a "perma-bear" means that many investors discount his warnings. However, if Caterpillar continues its recent slide, it will cement Burry’s status as one of the few managers capable of identifying systemic rot beneath a surface of record-breaking growth.

Conclusion

As of late June 2026, the battle lines are clearly drawn. On one side stands the momentum of the AI revolution and the undeniable need for power infrastructure—a trend that has made Caterpillar a surprise winner in the tech race. On the other side stands Michael Burry, armed with 30-year valuation charts and the memory of the 2000 and 2008 crashes.

Whether Caterpillar is a "bubble" waiting to burst or a "structural winner" in a new era of energy demand remains to be seen. For now, the "Big Short" investor has made his move, betting that even the strongest steel can bend under the weight of an unsustainable valuation. Investors across the globe will be watching the "yellow giant" closely, as its performance may well signal whether the AI boom is a lasting industrial shift or a speculative fever dream.
