U.S. economy grows at fastest pace in more than two years, third-quarter GDP shows

The U.S. economy expanded at its fastest pace in more than two years in the third quarter, according to the latest GDP report. The acceleration was attributed to two forces: a boom in artificial intelligence and strong spending by wealthier households. Together, these drivers helped push overall growth to a pace not seen in over two years.

For markets, the reading matters because GDP is one of the broadest gauges of economic momentum. Stronger growth can support corporate earnings expectations, but it also shapes how investors think about inflation, interest rates, and the path of monetary policy. The report's composition is as important as its headline: growth concentrated in AI-related investment and upper-income consumption may look different from a broad-based expansion.

What to watch next: whether this pace proves durable or reflects a narrow set of drivers, how the AI investment cycle evolves, and whether spending holds up across income groups. Subsequent data on inflation, employment, and consumer demand will help clarify the picture.
