ECB Warns Big Tech Accounts for 31.1% of S&P 500 Market Cap but 20.8% of Earnings
The European Central Bank warned on November 26, 2025, that Big Tech companies represent 31.1% of the S&P 500's market capitalization while generating only 20.8% of index earnings, according to its Financial Stability Review. The bank identified this valuation gap as a financial stability risk, noting elevated asset prices and market concentration could trigger sharp corrections if AI adoption disappoints or economic growth weakens. ECB Vice President Luis de Guindos distinguished current conditions from the dot-com bubble, citing established revenues and business models, but acknowledged valuation concerns.
