Warren Buffett Warned Investors About This Number 27 Years Ago. It's Never Been Higher. Should AI Investors Worry?
In 1999, Buffett said corporate profits couldn't stay much above 6% of the economy for long. They're now more than double that, and the AI spending boom is a big reason why.
In 1999, Warren Buffett cautioned investors about the growing share of corporate profits in the economy, which had reached a peak of 6% of GDP. However, by 2026, those profits had soared to 13%, the highest level ever recorded since 1929.
Buffett argued that as profits take an ever-growing slice of the economy, someone else, typically workers, must settle for a smaller portion. This concept could be particularly relevant for AI investors today, as tech companies have driven much of this year's earnings growth.
Some analysts estimate that more than 80% of AI-related revenue still comes from within the AI industry itself, rather than from outside customers. If spending slows down, those paper earnings may disappear. Factors such as rising labor costs and higher interest rates could put additional pressure on AI stocks.
Berkshire Hathaway, led by CEO Greg Abel, has been buying back shares aggressively, highlighting the potential of companies with durable competitive advantages. While AI stocks show promise, investors should focus on businesses with strong fundamentals and sustainable competitive edges.
