Warren Buffett Warns of Gambling Mood in Overvalued Market

Retired Berkshire Hathaway CEO Warren Buffett warned that current stock market valuations are dangerously high, comparing the current climate to the dot-com bubble of the late 1990s. In interviews with CNBC and during the company's annual shareholder meeting, Buffett characterized the prevalence of short-term risky investments as "gambling" and described the market as "a church with a casino attached."

Buffett noted that an unprecedented "gambling mood" makes it difficult to find value in the current environment. This perspective is supported by several financial metrics: the Buffett indicator—the ratio of total U.S. stock value to GDP—has reached a record high of over 232%, and the S&P 500 Shiller CAPE Ratio is at 41, its second-highest point in history. Additionally, U.S. investor margin balances have soared to a record $1.5 trillion since 2025.

Driven by optimism surrounding the artificial intelligence industry, where spending is projected to exceed $5 trillion by 2030, many stocks have become detached from business fundamentals. In response to these conditions, Berkshire Hathaway, under the leadership of CEO Greg Abel, has accumulated a record cash reserve of $397 billion.
