Legendary value investor Seth Klarman has drawn a clear line in the sand, challenging the market's prevailing AI enthusiasm.
In a recent interview, Klarman expressed significant caution about the AI sector, highlighting what he sees as "bubble-like features." His main concern centers on a potential 'reflexive bubble', where massive capital spending by tech giants fuels revenue growth for AI companies like Nvidia, which in turn boosts their valuations and encourages even more spending. With hyperscalers raising over $250 billion year-to-date and Nvidia posting record revenues, this cycle of investment feeding valuation looks increasingly risky to a value-focused investor like him. This is why he is avoiding direct investment in capital-intensive LLM platforms such as OpenAI and Anthropic, which constantly require vast sums of money to operate and grow.
So, where is he looking instead? Klarman is turning his attention to a deeply out-of-favor sector: commercial real estate (CRE). While office vacancies are at record highs and delinquency rates for commercial mortgages have been elevated, he sees opportunity in the distress. Recent data suggests a selective stabilization, with special servicing rates for mortgages beginning to dip. This creates a fertile ground for investors who can sift through the wreckage to find mispriced, high-quality assets—a classic value investing playbook.
This entire thesis is framed by a challenging macroeconomic backdrop. With headline inflation re-accelerating to 4.2% and U.S. public debt reaching nearly 100% of GDP, Klarman's caution is amplified. A higher-for-longer interest rate environment makes risky growth bets less attractive while increasing the strain on the CRE sector, potentially creating more bargains. The high national debt also limits the government's ability to respond to future economic shocks, reinforcing the need for a disciplined, risk-averse investment strategy.
Interestingly, Klarman did admit to one regret: missing an early investment in Palantir. The company's impressive 85% year-over-year revenue growth and strong margins show that profitable, high-growth businesses do exist in the tech world. However, this doesn't contradict his current stance. Palantir's success highlights the value of strong business fundamentals and operating leverage, a stark contrast to the cash-burning models of many LLM platforms he now avoids.
- Commercial Real Estate (CRE): Property used exclusively for business-related purposes or to provide a workspace rather than a living space. Examples include office buildings, industrial properties, and retail spaces.
- Commercial Mortgage-Backed Securities (CMBS): A type of investment product that is backed by mortgages on commercial properties rather than residential real estate.
- Reflexivity: A theory that investors' perceptions can influence market fundamentals, creating a feedback loop where rising prices attract more buyers, further driving up prices, which can lead to a bubble.
