Third-quarter U.S. GDP increases a better-than-expected 3.4% as September inflation accelerates

5 sources →

The U.S. economy grew at a seasonally adjusted annual rate of 3.4% in the third quarter of 2026, exceeding economist forecasts. This growth represents an acceleration from the 2.2% rate recorded in the second quarter. Key drivers included resilient consumer spending and significant business investment, particularly in the artificial intelligence sector. However, accompanying inflation data for September showed the Personal Consumption Expenditures (PCE) price index rose at an annual rate of 3.6%, remaining above the Federal Reserve's 2% target. Core inflation, which excludes volatile food and energy costs, stood at 3.1%. The reports come just days before the midterm elections, amid ongoing concerns about high prices.
