AI Stocks Now Represent 41% of U.S. Market, Matching 2000 Dot-Com Peak
The 10 largest artificial intelligence stocks now account for 41% of the U.S. stock market, according to data cited by Coin Bureau from Bank of America, a level comparable with the peak concentration reached during the dot-com bubble in 2000.
Coin Bureau said the comparison comes as U.S. Treasury yields have risen sharply since February. Citing Bank of America, the account pointed to three historical stock market bubbles in which rising bond yields accompanied the end of the boom.
AI Stocks Reach Dot-Com-Era Concentration
According to the data shared by Coin Bureau, the 10 largest AI stocks represent 41% of the U.S. stock market. Coin Bureau noted that the figure is at the same level where the dot-com bubble peaked in 2000.
The comparison focuses on market concentration rather than claiming that current market conditions are identical to those of 2000. The figures instead place the current weight of major AI-related companies within the broader U.S. equity market alongside a historical period of elevated concentration.
Bank of America’s analysis, as cited by Coin Bureau, also examined the role of bond yields in three previous market bubbles: the Nifty Fifty in 1973, Japan’s market in 1989 and the dot-com bubble in 2000.
Historical Bubbles and Rising Bond Yields
Coin Bureau highlighted Bank of America’s observation that each of those three episodes ended after bond yields increased by at least 2 percentage points.
During the Nifty Fifty period in 1973, U.S. yields rose by 2 percentage points. In Japan in 1989, Japanese yields increased by 2.3 percentage points. During the dot-com bubble in 2000, U.S. yields climbed by 2.6 percentage points.
The historical figures cited by Bank of America therefore identify a 2-percentage-point increase in yields as a common feature across the three episodes.
The comparison does not establish that a similar outcome will occur in the current market. The historical periods involved different economic and monetary conditions, and the data cited in the post is focused specifically on the relationship between markets bubbles and bond yields.
U.S. 10-Year Yield Has Risen Since February
Coin Bureau also highlighted the recent movement in the U.S. 10-year Treasury yield. According to the figures cited in the post, the benchmark yield has increased by 1.27 percentage points since February.
That move remains below the 2-percentage-point threshold identified in Bank of America’s historical comparison of the three previous bubbles.
Bank of America summarized its assessment with the statement: “Quickest way to end US boom is surge in bond yields.”
The observation places the current rise in Treasury yields alongside the elevated concentration of AI stocks in the U.S. market, while leaving open the question of whether yields would need to rise substantially further before resembling the historical episodes cited by the bank.
