Investor Michael Burry disclosed expanded bearish positions targeting AI-related stocks and semiconductor companies on June 30, 2026, via his Substack platform [1, 2]. He is betting against names including Tesla, Nvidia, Applied Materials, Caterpillar, and the SOXX semiconductor ETF, which tracks US chipmakers such as Micron Technology and AMD [1, 2].

Burry pointed to South Korean chipmakers Samsung and SK Hynix’s combined semiconductor investment plan exceeding $500 billion to build new chip parks. He views this massive capital expenditure as a sign the AI and semiconductor boom cycle may be peaking. He described it as “the beginning of the end,” saying, “When a whole industry starts competing by expanding capacity with astronomical investment scales, it often means markets have entered an overly optimistic phase” [1].

The Philadelphia Semiconductor Index trades about 65% above its 200-day moving average, underscoring elevated valuations in the chip space [2]. Burry holds put options on SOXX forecasting a sharp price drop by March 2027 and sees risks from high capital spending failing to translate into sustainable profits [1, 3, 2].

Tesla is another key target, with Burry shorting shares aiming for a $416.22 price point. He criticized Tesla’s valuation related to its autonomous driving and AI ambitions [1, 2]. Caterpillar was added recently due to valuation concerns amid the AI investment surge. The heavy-equipment maker’s stock surged 86% in the first half of 2026, catching Burry’s attention. He said Caterpillar “popped right in front of me,” noting he had never shorted the stock before and had previously made returns going long on it [2].

Burry has been warning about excessive valuations in AI concept stocks for months and highlighted emerging risks including US government intervention and rising costs of AI application development [1]. His prior predictions included long-term downtrends for Nvidia and Palantir Technologies. Nvidia’s shares fell about 5% after his 2025 short disclosure, while Palantir dropped about 40% [1].

Burry’s public disclosure on June 30, 2026 marks the latest step in his bearish stance on the AI and semiconductor sectors and sets focus on price levels and risk events through early 2027 [1, 2].
