October highlighted the resilience of the U.S. economy amid persistent inflation, rising interest rates, and growing uncertainty surrounding artificial intelligence investment. Third-quarter GDP expanded at a 3.4% annualized pace, supported by consumer spending and a 9.4% increase in business investment, largely reflecting the substantial AI infrastructure buildout. However, inflation remained stubborn, with September CPI rising 3.7% year-over-year and producer prices accelerating to 6.3%, marking the largest annual increase since December 2022 and reinforcing concerns that higher energy costs could prolong inflationary pressures.
