US Stock Market Hits Highs Amid Record Low Consumer Sentiment

The U.S. stock market is experiencing a significant disconnect as the S&P 500, Nasdaq Composite, and Dow Jones Industrial Average remain near all-time highs while consumer confidence collapses. The University of Michigan Consumer Sentiment Index fell just under 48 in September 2026, marking one of its lowest readings on record, surpassed only by the Great Recession and the 2022 inflation crisis.

Market growth is primarily driven by massive investments in artificial intelligence infrastructure. In the first half of 2026, Microsoft, Meta Platforms, Amazon, and Alphabet spent a combined $303 billion on data centers. This concentrated spending has sustained index levels despite the prevailing pessimism among the general public.

Financial analysts have expressed concern over the sustainability of this growth. Bank of America reports that approximately 45% of fund managers now identify an AI bubble as the primary tail risk facing the market.
