Investor Michael Burry shorted Caterpillar Inc. (NYSE: CAT) at $1,060.98 per share on Tuesday, citing overvaluation following a 172% stock rally over the past 12 months. Burry, known for predicting the 2008 housing crash, contends the surge reflects an AI-driven market bubble, while analysts argue the growth stems from fundamental infrastructure shifts.
The bet places Burry in direct opposition to a broader market trend where industrial giants are being reclassified as “AI plays.” While Caterpillar (NYSE: CAT) produces heavy machinery, its recent valuation leap is tied to the energy demands of massive data centers. If Burry is correct, the stock is a bubble waiting to burst; if the analysts are right, the company is simply evolving into a critical utility provider for the AI era.
The Bottom Line
- The Trade: Michael Burry entered a short position at $1,060.98, coinciding with a price-to-sales ratio at a 30-year high.
- The Bull Case: Demand for on-site diesel and natural-gas power systems is surging as AI data centers outpace the aging electrical grid.
- The Macro Risk: The valuation remains tethered to the aggressive capital expenditure (CapEx) of hyperscalers; any pullback in data center spending could trigger a correction.
Why is Michael Burry betting against Caterpillar’s AI rally?
Burry’s decision to short Caterpillar (NYSE: CAT) is not an isolated trade but part of a systemic bet against the current AI trajectory. In a Substack post this week, Burry noted that the stock “jumped out” at him, marking a departure from his historical preference for the company on the long side. He argues that the 172% climb over the last year has pushed the stock’s price-to-sales ratio to its highest level in three decades.
This move aligns with Burry’s broader warning in May that the current market environment mirrors the final months of the 1999-2000 dot-com bubble. Beyond Caterpillar (NYSE: CAT), Burry has refreshed short positions against the iShares Semiconductor ETF (NASDAQ: SOXX), as well as Tesla (NASDAQ: TSLA) and Nvidia (NASDAQ: NVDA).
But the balance sheet tells a different story for some. According to Caterpillar (NYSE: CAT)‘s first-quarter results, sales grew 22% year-over-year to $17.4 billion, beating Wall Street expectations. This fundamental growth is what critics of Burry’s trade point to as a shield against a crash.
Does the “AI Power Play” justify the valuation?
Sergey Glinyanov, a senior analyst at Freedom Broker, told Fortune that Burry is misidentifying the catalyst. According to Glinyanov, the rally isn’t based on “AI hype” but on a structural shift in how power is delivered to infrastructure. As AI campuses expand, they require reliable, on-site power systems to bypass an aging electrical grid that cannot keep pace with energy needs.

Caterpillar’s diesel and natural-gas generator systems have become essential for these hyperscalers. This trend has created a new class of “AI-adjacent” winners. For example, GE Vernova (NYSE: GEV), specializing in power generation, has seen shares rise more than 60% year-to-date. Similarly, Vertiv Holdings (NYSE: VRT), which provides cooling systems for data centers, has climbed 70% in the same period.
Here is the math on the recent volatility following Burry’s disclosure:
| Metric/Event | Value/Change | Context |
|---|---|---|
| Burry Short Entry Price | $1,060.98 | Tuesday Entry |
| Wednesday Close | ~7% Decline | Immediate Market Reaction |
| Thursday Low | ~$949.00 | Lowest point since mid-June |
| 12-Month Rally | 172% | Pre-short growth |
| YTD Growth | >77% | Pre-short growth |
What happens if the hyperscalers cut spending?
While Glinyanov maintains that Caterpillar (NYSE: CAT)‘s traditional heavy machinery business remains healthy—citing improving dealer inventories and steady retail demand—he acknowledges a critical vulnerability. The premium valuation is entirely dependent on the continued aggressive spending of the world’s largest AI companies.
Glinyanov warned Fortune that if there is a “deterioration in hyperscalers’ fundamentals,” specifically regarding debt burdens or cash flow generation, the stock’s multiples could face a “meaningful pullback.” His firm currently holds a price target of $910, suggesting that even the bulls anticipate a near-term correction.
This dynamic creates a precarious bridge between the industrial economy and the digital one. If the SEC filings of major tech firms show a pivot away from infrastructure build-outs, the “structural theme” Glinyanov describes could evaporate, validating Burry’s bubble thesis.
The broader market implication for industrial stocks
The clash between Burry and Glinyanov highlights a growing divide in market sentiment: whether industrial companies are fundamentally transforming or are simply being swept up in a speculative mania. If Caterpillar (NYSE: CAT) corrects sharply, it could trigger a sympathy sell-off in other power-infrastructure stocks like Vertiv (NYSE: VRT) and GE Vernova (NYSE: GEV).

The market is currently pricing these companies not as machinery manufacturers, but as essential conduits for AI growth. For institutional investors, the risk is no longer about whether Caterpillar (NYSE: CAT) can sell a tractor, but whether the global energy grid remains the primary bottleneck for AI scaling. If the bottleneck is solved—or if the demand for AI compute peaks—the premium valuation of these industrial giants will likely collapse.
