# Bank of England: AI valuations have pushed the valuation multiples of some U.S. stock indices to levels seen at the peak of the internet bubble

> The Bank of England pointed out in an article that the valuations of AI-related assets have pushed the valuation multiples of some U.S. stock indices to levels seen at the peak of the internet bubble. Although AI may bring economic transformation, various factors have increased the uncertainty of future profit growth expectations. Additionally, tens of trillions of dollars in investment will be needed for the infrastructure supporting AI models over the next five years, primarily relying on debt financing. The article discusses the potential impact of falling AI asset prices on financial stability

The Bank of England published an article titled "All in Chips! Will the Collapse of AI-Related Asset Valuations Trigger Financial Stability Consequences?"

The article states that the share of "artificial intelligence (AI) stocks" in the market capitalization of U.S. stock indices is increasing.

The valuation multiples of these companies often imply high expectations for future profit growth.

These two facts have pushed the valuation multiples of some U.S. stock indices to levels seen at the peak of the internet bubble.

While artificial intelligence may have transformative economic impacts, which could justify these valuations, various factors make this outcome uncertain.

Additionally, the physical infrastructure needed to support AI model training and inference is expected to require trillions of dollars in investment over the next five years, a significant portion of which will be funded by debt.

The article discusses the potential impact of declining asset prices influenced by artificial intelligence on financial stability, as well as how these impacts may grow in the future
