Article Text

Michael Burry revealed on Tuesday that he has opened a short position against Caterpillar, arguing that the company has emerged as one of the most overvalued beneficiaries of the surge in AI-related investing. Burry said he shorted Caterpillar at $1,060.98 and simultaneously initiated bearish positions in several other high-profile names, including Nvidia, Applied Materials, Tesla and the iShares Semiconductor ETF (SOXX). These moves reflect his view that the recent rally in AI-linked stocks has become overstretched.

Burry noted that Caterpillar's stock has posted extraordinary gains, finishing the first half of 2026 up about 86%. That performance places the construction-equipment maker among the top performers in the S&P 500 this year, as investors increasingly treat it as a proxy for spending on global AI infrastructure. He pointed to valuation metrics that he considers striking: a chart Burry shared shows Caterpillar's price-to-sales ratio rising to its highest level in at least thirty years, coinciding with record-high share prices.

Drawing on his reputation from correctly anticipating the 2008 subprime crisis, Burry reiterated broader concerns about semiconductor valuations. He highlighted that the Philadelphia Semiconductor Index is trading roughly 65% above its 200-day moving average, a deviation he says has historically appeared only during extreme market episodes like the dot-com bubble in 2000. For Burry, such departures from long-term trends are warning signs of a rally's fragility.

Burry attributed the proximate trigger for the recent rally to large spending announcements from Korea, but he characterized that development as potentially the beginning of the end for the current upswing. He warned that while the spending news has driven enthusiasm, it may also mark a peak in investor optimism that precedes a correction. He sees the market as increasingly vulnerable and a reversal as only a matter of time.

His short on Caterpillar is notable given his history with the stock: Burry said he had never shorted Caterpillar before and that it had previously been a reliable long position for him. The new stance underscores how dramatically his view of the company has shifted amid the AI-driven narrative. By also shorting semiconductor-related assets and other high-flying names, Burry signaled a broader skepticism about the sustainability of gains across sectors tied to AI investment themes.

Investors and market observers will likely weigh Burry's call alongside other indicators, including corporate fundamentals, macroeconomic conditions and continued announcements of capital spending by tech and infrastructure players. While Burry's previous prescient bets lend weight to his warning, market reactions can be variable and influenced by many factors beyond valuation ratios. His commentary adds to a growing debate over whether the AI-led rally is grounded in durable earnings prospects or inflated expectations.

Ultimately, Burry's actions illustrate a cautious, contrarian stance: taking tangible bearish positions in response to what he interprets as extreme valuation signals. Whether his timing proves prescient will depend on how corporate investment, supply chains and broader market sentiment evolve in the months ahead.
