S&P 500 Falls As AI Tech Stocks Get Reality Checked
The S&P 500 (Index: SPX) fell 1.6% from its previous week's close as investors developed higher anxiety over the future of firms betting big on Artificial Intelligence (AI) systems. The index ended the first trading week of November 2025 at 6,728.80.
The state of AI-tech stocks provided the biggest market-moving story of the week that was. High-flying AI stocks got their first major reality check since April 2025. Many stocks were pulled lower as investors weighing recent earnings reports found the firms' capital spending to be higher than expected, lowering both their free cash flow and future earnings expectations.
For the S&P 500, that pulled the entire index lower because of the outsize share of just a handful of tech firms among the component stocks that make up the index.
The shift of investor focus toward future earnings can be seen in the latest update to the alternative futures chart. The trajectory of the S&P 500 moved in a new Lévy flight event, as investors shifted their attention from the near term future of 2025-Q4 toward the more distant investment horizon of 2026-Q2.
That shift occurred despite the continuation of mixed messages from Federal Reserve officials, which had dominated investor attention in the preceding two weeks. The week's market moving headlines capture that noise and also the investor anxiety arising over the big AI-technology related bets being placed by the market's biggest companies.

The CME Group's FedWatch Tool indicates a 72% probability of one more quarter point cut to the Federal Funds Rate in 2025, coming on 10 December (2025-Q4). In 2026, the FedWatch tool anticipates better than 50% probabilities for quarter point rate cuts on 18 March (2026-Q1) and 29 July (2026-Q3), which is earlier than last week. The potential timing of these rate cuts remains very fluid at this time.
The Atlanta Fed's GDPNow tool projection of real GDP growth in the U.S. during the recently ended 2025-Q3 ticked up to +4.0% from +3.9%, even though many economic data reports remain on hold because of the Senate Democrats' ongoing refusal to fund government operations. The BEA's official estimates of GDP in 2025-Q3 remain on hold as well.
