Michael Burry Bets Against AI Chip Stocks: Should You Worry?
💡 Key Takeaway
Michael Burry's short position on the iShares Semiconductor ETF signals a potential overvaluation in AI chip stocks, but investors should weigh the risks of betting against strong momentum.
What Happened: Burry Goes Short on Semiconductors
Michael Burry, the investor famous for betting against the housing market before the 2008 crisis, has revealed a new short position. As of June 30, he is short the iShares Semiconductor ETF (SOXX), which holds top AI chip stocks like Nvidia, AMD, Micron, and Broadcom.
Burry has been vocal on social media about his skepticism regarding the AI spending boom. He believes the semiconductor industry is overvalued, with the ETF trading at a price-to-earnings ratio of 74.3—more than double the Nasdaq-100's P/E.
His short bet means he profits if the ETF's value declines. The ETF has a concentrated portfolio, with over 36% in its top five holdings: Micron (8.16%), AMD (8.15%), Nvidia (7.50%), Broadcom (6.56%), and Intel (6.17%).
Burry's move comes despite these companies reporting explosive growth. Micron's revenue surged 345% year-over-year, and Nvidia's revenue has grown sevenfold in three years. However, Burry questions the sustainability of this growth, citing a UBS survey that found 60% of businesses are curbing AI spending.
Why It Matters: A Warning for AI Stock Investors
Burry's short position is significant because it targets the entire semiconductor sector, not just one company. If he is right, it could signal a broad correction in AI-related stocks, which have driven much of the market's recent gains.
The key risk Burry highlights is the disconnect between chipmakers' soaring revenues and their customers' profitability. Companies like Nvidia and AMD are selling billions in chips, but their customers—AI startups and cloud providers—are struggling to turn AI into profits. This could lead to a pullback in hardware spending.
For investors, this raises questions about valuation. The iShares ETF has returned 54% annually over the past three years, far outpacing the S&P 500. Such momentum can be fragile if sentiment shifts. Burry's track record adds weight to his caution, but timing the market is notoriously difficult.
Even if Burry is wrong in the short term, his thesis highlights a fundamental risk: AI spending may not be as sustainable as current prices suggest. Investors should monitor earnings from both chipmakers and their customers for signs of slowdown.

Investors should reduce exposure to semiconductor ETFs and AI chip stocks given overvaluation and spending risks.
Burry's short position is backed by valid concerns: high P/E ratios, slowing AI spending, and a disconnect between chipmakers and their customers. While momentum could continue, the risk-reward is unfavorable for new buyers. A correction of 20-30% in SOXX is plausible if sentiment shifts.
