Market Volatility Rises Amid AI Investment Concerns and Shifting Rate Expectations
November 2, 2026
U.S. financial markets ended the week of Oct. 30 on a volatile note, as concerns over elevated technology valuations, substantial artificial intelligence (AI)-related capital expenditures and disappointing results from several high-profile technology companies weighed on investor sentiment. Major equity indexes declined, with technology shares coming under particular pressure.1 The sharpest losses occurred late in the week, as earnings reports from major technology companies, including Alphabet and Amazon, renewed questions about whether massive AI investments will generate sufficient returns.2 Geopolitical tensions involving Iran and concerns about Middle Eastern energy supplies also contributed to market volatility, pushing oil prices higher.3
Meanwhile, the Federal Reserve (Fed) held interest rates steady at 3.75%–4.00% at its October meeting despite ongoing inflation concerns.4 Strong third-quarter gross domestic product (GDP) growth of 3.4% (annualized) provided further evidence of economic resilience, although underlying price pressures remained elevated.5 The combination of resilient growth, inflationary concerns, geopolitical uncertainty and questions regarding the returns on AI investments continued to weigh on investor sentiment. Overall, the week highlighted the delicate balance between a resilient U.S. economy and mounting concerns about inflation, interest rates and stretched corporate valuations.
Tomorrow’s U.S. midterm elections and Friday’s October employment report will be the primary events to watch this week.6 The election results could have meaningful implications for the policy and regulatory outlook, while the employment report will provide another important indication of economic momentum and inflationary pressures. Although the Fed held rates steady last week, markets continue to anticipate the possibility of another rate increase at the Dec. 8–9 meeting, with the probability of a hike estimated at approximately 75%.7 Fed Chair Kevin Warsh declined to signal the Fed’s next move, emphasizing the importance of evaluating incoming economic data.8 A stronger-than-expected employment report, particularly if accompanied by continued wage pressures, could reinforce expectations of further monetary tightening.
