Steve Eisman, the investor famous for betting against subprime mortgages before the 2008 crisis, has sold his long-held Google position and is now sitting on cash. He says the entire market has become a single AI trade — and that concentration is dangerous for stocks, bonds, and even crypto.
Why Eisman sold
Eisman told CNBC he dumped Alphabet to reduce his AI exposure. He's not buying defensive stocks either. He's just holding cash. His reasoning: investors either want AI or they want nothing. That leaves the market with no real diversification.
Alphabet peaked at $408.61 on May 18 and closed at $319.74 on July 24 — a drop of roughly 20% in about two months. The stock fell 7.1% on July 23 after Q2 earnings and a raised 2026 capital spending guidance to $195-205 billion. Eisman sees that kind of spending as a bet that could backfire.
The numbers behind the AI trade
Eisman argues that even a classic 60/40 stock/bond portfolio isn't diversified. Over 50% of stocks are tech or AI-related, he says, and most new bond issuance is AI-related. The actual numbers are more nuanced but still striking.
Information Technology and Communication Services combined make up 46.5% of the S&P 500. Add Amazon and Tesla and you get 51.5%. On the bond side, High Technology made up 14.2% of US corporate bond issuance in Q2 — not 'most' as Eisman claimed, but AI hyperscalers accounted for over 15% of this year's issuance by early May. In non-refinancing US high-yield issuance, AI hyperscalers took 41%, despite having just a 1% index weight.
Amazon priced $37 billion of notes on March 10. Meta raised $30 billion in October and another $25 billion in April, with proceeds for general corporate purposes. That's a lot of debt tied to AI ambitions.
Crypto caught in the crossfire
Bitcoin trades near $64,980, down about 45% over the past year. A Big Tech selloff in June dragged Bitcoin lower. Retail flows have favored semiconductor ETFs over crypto funds this year. Chinese hedge funds have started trimming AI winners.
If Eisman is right and AI spending doesn't deliver, a correction could hit risk assets broadly. The Bank for International Settlements warned that fixed income is vulnerable if hyperscalers slow capital spending. Crypto, already under pressure, would likely feel the pain.
What Eisman sees next
Eisman isn't shorting the market. He expects AI technology to succeed — but not all companies will. The question is which ones. For now, he's on the sidelines, watching a market that looks like one giant bet on AI.
The next concrete test: whether Alphabet and other hyperscalers maintain their spending pace through 2027. If they cut, the bond market could wobble. If they keep spending and revenue doesn't follow, stocks could tumble. Either way, Eisman isn't buying.
